Welcome to VA Smalltalk Version 8.5.1

VA Smalltalk enables software developers to create highly portable, scaleable, multi-tier business applications using object-oriented technology. VA Smalltalk allows for incremental and rapid development of new Smalltalk applications. Developers can build and deploy enterprise Web service solutions for dynamic e-business using VA Smalltalk.


What's New in V8.5

What's New in V8.5.1


Late-breaking news, technical tips, and product updates

Please refer to the Instantiations Smalltalk home page for technical information including tips and product updates made after this product release. The web page includes information about what's included in the release, and how to contact us as well as hints and tips for using and deploying VA Smalltalk.

You can download the latest product updates, as well as product add-ons, from the Instantiations Smalltalk download page.


Version 8.5.1 files and installation

Distribution files

Each supported VA Smalltalk platform has three downloadable components:

Client
The Client component contains the VA Smalltalk development IDE. You will need to install a client on each machine on which you wish to develop VA Smalltalk applications. You must download and install the correct client package for your workstation operating system.
Manager
The Manager component contains the VA Smalltalk source code repository ('manager') file and the EMSRV code used to access the repository file in a team environment. The manager is used in conjunction with the workstation client IDE. One code repository can support many clients concurrently. Therefore you will only need to install the manager one time on a suitable server machine. You must download and install the correct manager package for your server machine's operating system. It does not have to match the client operating system. A Linux manager install, for example, can concurrently service Windows, AIX, Solaris and Linux clients. The same is true for all of the other manager installs.
Server Runtime
This is the runtime support needed for deploying Smalltalk applications developed using VA Smalltalk. There is no formal install program for Server Runtime. You simply use unzip to unpack the runtime files and add your packaged Smalltalk application into the resulting directory structure. You must download and unpack the correct Server Runtime package for your workstation operating system. The files needed to include at runtime are listed in Redistributable Runtime Files.

If you do not already have a suitable unzip program, then you can download a no-charge unzip program such as Info-ZIP.

Note: The gunzip program will not work with the VA *.zip files. The VA *.zip files are multi-file archives; gunzip is only designed to handle single compressed files.

You must unzip the client and manager zips on the same kind of machine that you intend to install them on. Do not, for example, unzip a Solaris client install onto a Windows machine.


Installing VA Smalltalk

Complete install instructions, such as how to set up EMSRV, can be found in the Installation Guide. The Installation Guide is in the doc directory of the unzipped client or manager install directory tree (it is the same document in both zip files):

Note: There are special steps for installing on UNIX and Windows Vista or Windows 7 which are documented in the Installation Guide.

The Installation Guide is also available online.

To install VA Smalltalk, follow the instructions for your specific platform.

We recommend you install the manager before you install the client.

If you are new to Smalltalk, we recommend you install the client with the on-line documentation. Once you have installed the manager and the client, refer to the Installation Guide for further instructions on how to configure your environment before you launch VA Smalltalk.


VA Smalltalk Migration Guide

If you have a version of VisualAge Smalltalk or VA Smalltalk already installed, please refer to the Migration Guide for important information before using VA Smalltalk V8.5.1. The Migration Guide can be read online at Migration Guide  or it can be installed with the VA Smalltalk Client by selecting the "VA Smalltalk Documentation" feature.

Components and Features

The following sections list some important information about some of the components and features. For the latest product information, please refer to Instantiations Smalltalk web page.


Application Builder

On AIX, turn NumLock off when dropping parts

Be sure that your numlock key is turned off if you are using the composition editor. The numlock will prevent parts from being dropped on the Composition Editor.

On UNIX, "X Error: BadWindow" message appears for Slider part

Each time the Slider part is repainted the "X Error: BadWindow (invalid Window parameter)" message is printed in the xterm window where VA Smalltalk was launched.

The Slider part still functions normally.


Base

(8.5) Limitations to CwRebar

The rebar control consists of one or more bands, each of which may contain a child widget control. Neither the color of the rebar control nor the colors of the individual bands is settable. Rebars with fixed-width bands should be placed in a fixed size window.

On MVS, INIs are optional for packaged applications. All other platforms, INIs are required for packaged applications

On MVS, an .ini file is optional. On all other platforms, an .ini file is required. The .ini file may have the same name and be in the same directory as your executable (on Unix, the executable is es or esnx). The .ini file can also have the same name and be in the same directory as your .icx or .ic file.

In addition, you can specify your .ini file as a command line parameter. For example, you can launch your program by typing the following:

   abt -imyapp.icx -ini:c:\any.ini

(8.5.1) VerifyMemorySpaces, VerifyVMSlots, VerifyImage

VerifyMemorySpaces, VerifyVMSlots, VerifyImage can be used to identify Smalltalk memory corruption. Since these primitives write to the TTY Transcript, the image to be verified must be started with the '-l' commandline option in order to collect the verification information.


Communications

No additional information at this time.


Database

Get schema function on Stored Procedure Specification Settings

When using stored procedures with the new Oracle 8 database connection, the Get schema function on the Stored Procedure Specification Settings view only works for procedures that are not contained in packages. Users must manually define host variables for procedures that are contained in packages.

On Unix, running Database Features

On Unix, if you are using database features and experience a core dump when exiting VA Smalltalk, comment out the PlatformLibrary>>shutDown method. An alternative solution for your packaged application is to execute the following code when exiting:

   System primitiveExit

Oracle initialization mode can be changed without subclassing AbtOracle8DatabaseManager

Prior to this fix, the only provided method for changing the Oracle initialization mode was to create a subclass of AbtOracle8DatabaseManager in order to override the #userDefinedInitializeMode method. While this method is still available, it is now possible to change the default initialization mode by setting a class variable. The provided method for doing this is AbtOracle8DatabaseManager class>>#defaultInitializeMode:. The shipped default value is OCI_DEFAULT, which is unchanged from previous VA Smalltalk version. See the comment in AbtOracle8DatabaseManager class>>#defaultInitializeMode: for other possible values.

Prerequisite AbtRecordStructureApp in Database Applications

Some database applications will need to add a prerequisite for the AbtRecordStructureApp application. Applications that use Database Parts will not need to add this prerequisite because the parts will include the AbtRecordStructureApp application. If an application manipulates instances of any of the subclasses of AbtRow, they will probably need to add this prerequisite.

If you package your application and get the error The attribute Pub <Attr name> does not exist at runtime, you need to include the AbtRecordStructureApp application.


DBCS

Display Resolution for DBCS machines

To ensure all information is displayed on your computer, we encourage you to use the highest resolution offered by your display terminal.


Documentation and Helps

Identifying browser and newsreader on Unix

If you get no response from Smalltalk when requesting Help (from the Help menu or F1), the most likely cause is that the browser and/or the newsreader installed on the system cannot be found.  To correct this problem, edit the .ini file (for example, abt.ini) and add links to the installed browser and/or newsreader in the [Help] stanza -- you will see examples of specifying Firefox and Thunderbird. You can specify either a complete path to the browser and/or newsreader (not usually necessary) or a relative path.

Starting online help on Unix

Enter one of the following URLs into your browser:


Domino Connection

Using an English version of Lotus Notes

The NLS versions of Lotus Notes must be installed on the native Operating System (OS) platforms, in order for Notes to work. If a US-English version of Lotus Notes is installed on the native OS, then the user will not be able to input either SBCS or DBCS characters correctly. This is a restriction with Lotus Notes.

Error detaching documents using Domino Connection

When detaching a file attachment using the Domino connection, the detached file is corrupted. The problem only shows up if the attachment is BASE64 encoded.  Detaching the same attachment using the Notes Client works fine. Detaching via Domino connection also works fine if the file has been attached manually using the Notes Client.


EMSRV

EMSRV support for Windows NT/2000 on SMP hardware

There are no known current issues with multiprocessor boxes under any recent version of Windows.  Under much older versions of Windows, such as Windows NT, repository corruption was observed on multiprocessor machines. It was never reproducible or diagnosed, but speculation at the time was that the problem was a file sharing bug in Windows itself (that has likely been long since corrected). As far as we know, no fix is necessary under any recent version of Windows.
 
As long as you use the -mp switch, you should not have any problem using EMSRV under any recent version of Windows.  We have had no reports of manager corruption in the past 5 years or more. Many customers are successfully running EMSRV with the -mp override.
 
In any case you should always make sure to have a current backup available in case there is any  sort of problem.
 
If you are still concerned about this issue, you can run EMSRV on a single processor box or use a single-processor VMWare image.
 
Note: Without the override results in a warning
 
    WARNING:  Running EMSRV for Windows NT/2000 on multiprocessor hardware is not supported due to
    suspected operating system bugs that may result in repository corruptions.  Install and run EMSRV
    on a machine with a single processor or start EMSRV with the -mp option to bypass this check.
   
Note: When starting with the -mp command line option, EMSRV will still report a warning to the console (or to the Application Log if EMSRV is running as a service):
 
    WARNING:  Running EMSRV for Windows NT/2000 on multiprocessor hardware is not supported due to
    suspected operating system bugs that may result in repository corruptions.  You have chosen to
    start EMSRV with the -mp option to bypass a check that normally restricts EMSRV from running on
    multiprocessor hardware.  This may cause repositories to become corrupted.

(7.5.2) Native password validation on Linux

EMSRV native password validation on Linux uses Pluggable Authentication Modules (PAM). The sample PAM file shipped with VA Smalltalk is correct for older Linux distributions, but does not work for newer distributions.


OLE

Copying from Windows Explorer into an OLE Client part

Use copy and paste to share OLE objects between the Windows Explorer and an OLE Client part. Dropping an OLE object that was dragged from the Windows Explorer onto an OLE Client part does not work.


Packaging

No additional information at this time.


Server

(7.5.1) HTTP server access log

An SST HTTP server can write an "access" log containing an entry for each request received by the server. Entries in the log are formatted according to the default format used by the Apache HTTP server in order to enable tooling for Apache logs to be used for SST logs as well.

The access log is initialized in SstHttpServer>>startUp.  If an access log is desired, it can be specified in 2 ways:

  1. The application can send SstHttpServer>>accessLogFormatPolicy: AND SstHttpServer>>accessLog: prior to sending SstHttpServer>>startUp.
  2. The application can be started with the following command line switch: -sstaccesslog.  This will cause a log file named httpd.log to be written in the current directory.

(8.5) Performance improvement in writing walkback log

By default, when an error occurs, the walkback information is written to TranscriptTTY. This causes the walkback information to be written to the console or to a log file identified by the -l command line option. Since TranscriptTTY output is written unbuffered character-at-a-time, it can be very time consuming to write a large volume of walkback information.

An alternative output mechanism is avasilable. When it is enabled, this mechanism writes the walkback information to a file stream. This is a buffered operation which can be more than an order of magnitude faster than writing to TranscriptTTY.

To enable writing the walkback information to a file stream, you must provide the name of the walkback log in the .INI file:

  [Kernel]
  walkbackFilename=myWalkback.log

(6.0) SST IIOP Support is Obsolete

CORBA IIOP facilities provided by SST in previous releases are obsolete as of this release. The implementation provided in previous releases continues to be shipped with this release, but all methods have been recategorized as 'OBSOLETE'. There will be no further development or enhancement of these facilities, and they may be removed from the product in a future release.

Customer applications which made use of these facilities in a previous release will continue to be supported as they are migrated to this current release.

Customers are advised to make use of Web Services technologies, such as XML and WSDL, for future interoperability strategies.

(8.0.2) Support for JDK 1.3 through JDK 1.6 using RMI

The RMI in Server Smalltalk has been tested with JDK 1.3 through JDK1.5, using the same techniques that were required for JDK 1.2.

Using XD Interactive Debugger over TCP/IP with no nameserver

When trying to use the interactive debugger, if you are getting the error EHOSTNOTFOUND or EADDRNOTAVAIL on the runtime side, the problem may be that your runtime machine cannot resolve the dotted TCP/IP address of your development machine. You can work around this problem by adding an entry to the hosts file on the runtime machine for your development machine.


VA Assist

Uninstalling VA Assist

Uninstalling VA Assist is a bit involved. To uninstall the feature,

  1. Start with an image named the generic name: abt.icx.
  2. Launch the image.
  3. Disable VA Assist (From the Transcript choose Tools -> VA Assist Pro -> Disable.)
  4. Save (using the Transcript -> File -> Save Image) and restart the image.
  5. Uninstall the feature. There are two ways to do this:
    1. From the Transcript choose Tools -> Load/Unload Features...
      Select VA: VA Assist Pro from the right pane and move it with the << button to the left pane. Dismiss the dialog with an OK.
    2. From the Transcript choose Tools -> VA Assist Pro ->Uninstall.
  6. Save the image using the Transcript -> File -> Save Image.
  7. If you renamed your image, restore its former name.

Web Connection

Web Connection does not support DBCS char for Cookies

DBCS cookies are not supported using the Servlet Interface. This is a limitation of the HTTP Server.


WebServices

(8.0) Deserialization of a SOAP Envelope failed when the defining schema contained an element using a ref attribute referring to an imported schema

  Consider the following excerpt from the schema and mapping specs:

  Schema 1:

  <?xml version="1.0" encoding="UTF-8"?>
  <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
        xmlns="http://exampleSchemas.com/thisSchema"
        xmlns:ais="http://exampleSchemas.com/StatusSchema"
        targetNamespace="http://exampleSchemas.com/thisSchema"
        elementFormDefault="qualified"
        attributeFormDefault="unqualified">
      <xs:import namespace="http://exampleSchemas.com/StatusSchema"   schemaLocation="StatusSchema.xsd"/>
      <xs:element name="SessionRequest" type="StartSessionRequestType"/>
      <xs:element name="SessionResponse" type="StartSessionResponseType"/>
      <xs:complexType name="SessionRequestType"/>
      <xs:complexType name="SessionResponseType">
            <xs:sequence>
                  <xs:element ref="ais:Status" minOccurs="0" maxOccurs="unbounded"/>
                  <xs:element name="SessID" type="xs:string" minOccurs="0"/>
          </xs:sequence>
      </xs:complexType>
  </xs:schema>


  Mapping Spec for SessionRequest:

  <?xml version="1.0"?>
  <!DOCTYPE XmlMappingSpec SYSTEM "abtxmap.dtd">
  <!-- NameSpaceURI must match with the namespace on the Schema                       -->
  <XmlMappingSpec Name="StartSession.map" NameSpaceURI="http://exampleSchemas.com/thisSchema" >    
    <ClassTypeMapping TypeName="SessionRequest" ClassName="ExStartSessionRequest"/>
    <ClassTypeMapping TypeName="SessionResponse" ClassName="ExStartSessionResponse">
            <AttributeMapping ClassAttribute="status" NameSpaceURI="http://exampleSchemas.com/StatusSchema">
                  <SubElement>Status</SubElement>
            </AttributeMapping>
            <AttributeMapping ClassAttribute="sessionId">
                <SubElement>SessID</SubElement>
            </AttributeMapping>
    </ClassTypeMapping>


  Mapping Spec for Status:

  </XmlMappingSpec>
  <?xml version="1.0"?>
  <!DOCTYPE XmlMappingSpec SYSTEM "abtxmap.dtd">
  <!-- NameSpaceURI must match with the namespace on the Schema                       -->
  <XmlMappingSpec Name="TransactionStatus.map" NameSpaceURI="http://exampleSchemas.com/StatusSchema">

    <ClassTypeMapping TypeName="Status" ClassName="ExStatus">
            <AttributeMapping ClassAttribute="returnCode">
                  <SubElement>Code</SubElement>
            </AttributeMapping>
            <AttributeMapping ClassAttribute="returnCodeDescription">
                <SubElement>Description</SubElement>
            </AttributeMapping>
    </ClassTypeMapping>
  </XmlMappingSpec>


  After deploying the web service and sending a request,  the web services framework did not 
  deserialize this response:

  <?xml version="1.0" encoding="UTF-8" standalone="yes"?>
  <env:Envelope xmlns:env="http://schemas.xmlsoap.org/soap/envelope/"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/"
         xmlns:xsd="http://www.w3.org/2001/XMLSchema">
       <env:Body>
        <SessionResponse xmlns="http://exampleSchemas.com/thisSchema"        
       <Status xmlns="http://exampleSchemas.com/StatusSchema">        
             <Code>0</Code>
            <Description>ok</Description>
              </Status>
              <SessionID>ABCDEF</SessionID>
        </StartSessionResponse>
    </env:Body>
  </env:Envelope>

  It reported the error: 

  "XML mapping error ##ObjectInitializationError: ''Unable to process element ''''TransactionStatus'''''''   ".
 
  The problem occurred because the code considered the Status  element to be in the 
  "http://exampleSchemas.com/thisSchema" namespace, not in the namespace of the imported schema. 
  The framework was  modified to take into account the namespace of the prefix on an element with a ref
  attribute.  

(8.0) WSDL deployment fails when a schema attempts to import a schema which is already being imported

The schema parser in VA Smalltalk is recursive. Whenever a schema import is encountered, a new parser is created which begins to parse that schema. The new parser is added to a stack. This process continues until there are no more schemas to be imported; then the final schema import is completed. The previous import is then completed until the stack is unwoundd. If an imported schema imports a schema which has already been imported by a previous schema, an infinite loop results and an out of memory condition is encountered. For example:

  WSDL A imports Schema A.

  Schema A imports Schema B.

  Schema B imports Schema A.

Modifications were made to track schemas which have currently begun to be imported and to skip duplicate imports.

(8.0) WSDL and imported schemas using the document/literal or document/literal wrapped style are not deployed/serialized properly

  Deployment Problem

  The typical error message in this situation occurs during deployment with the message:

  'The type an AbtXmlQName(requestheader:WachoviaRequestHeader) for WSDL part ''SomeWSDLPart'' could not be determined'

  The problem occurred when the "document/literal wrapped" style of wsdl was used and the element
  was defined in an imported namespace, e.g.,

  <wsdl:definitions

    ...

    xmlns:importedNamespace="myNamespace2"

  <wsdl:types>

    <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">

      <xs:import namespace="myNamespace2" schemaLocation="C:\aSchemaLocation"/>

    </xs:schema>

  </wsdl:types>

  <wsdl:message name="RequestMessage">

      <wsdl:part element="importedNamespace:Request" name="Request"/>

  </wsdl:message>
 
  An instance of the SstWsdlDefinitions class contains the parsed artifacts of the web service including
  the schemas defined or imported in the types section.  WsdlDefinitions has an instance variable "types"
  which contains an instance of the SstWsdlTypes class.   namespacemappings instance variable.  During parsing
  of the types section, schema namepsaces were added  to a dictionary assigned to this variable.  The schemas
  themselves were placed into the schemas instance variable. Only namespaces of schemas defined wtihin the section
  and schemas directly imported within the types section are included.  However, these imported schemas often
  import other schemas.  The imported schema's namespaces and prefixes are not assigned to the schemas dictionary;
  they appear in the WsdlDefinitons types instance variable in its imports dictionary.  Since this dictionary is
  not searched during the deserailziation/serialization process, nor during the wsdl message parsing process, web
  services with this type of schema importation could not be deployed or serialized/deserialized.  

  Code was added to cache all namespaces contained in  imported schemas during parsing; when all schemas were
  imported, iterate through the cache and:

   1. place all namespaces into the SsdWsdlDefinitions namespaceMappings Dictionary

   2. place all schemas in the SstWsdlTypes schemas dictionary


  Serialization Problem

  All necessary namespaces were not included in the Soap request envelope if imported namespaces and
  schemas were needed to fully define the request.

  Code was added to examine all schema elements included in the request and to add their namespaces to
  the Soap envelope.

  Important!

  In order to retain backward compatibility, the new processing has been made optional on a container--wide
  basis.  To use it, create a container using:

    SstWSContainer>>createContainerUsingDocLiteralWrappedNamed: aString

(8.0) An Element with a ref attribute referring to another namespace was serialized incorrectly in the SOAP Envelope

  A schema element which contained a ref attribute to a type in another namespace was not serialized with
  the correct prefix in the Soap request envelope.

  Consider the following excerpt from a schema: 

  ...

  <xs:schema  xmlns:thisNamespace ="http://thisnnamespace.net/"
            xmlns:cust ="http://customer.net/"
            targetNamespace="http://thisnnamespace.net/" >
  <xs:import namespace="http://customer.net/" schemaLocation="C:\theSchemaLocationl"/>
      <xs:element name="StatementRequest">
            <xs:complexType>
                  <xs:sequence>
                        <xs:element ref="cust:Customer"/>
                  </xs:sequence>
            </xs:complexType>
      </xs:element>


....


   Prior to V8.0, the SOAP serialization would produce the following in a request envelope:

   <SOAP-ENV:Envelope
       xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"
       xmlns:thisNamespace ="http://thisnnamespace.net/"
      xmlns:cust ="http://customer.net/"
       xmlns:xsd="http://www.w3.org/2001/XMLSchema"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
      <SOAP-ENV:Body>
            <thisNamespace:StatementRequest>
                  <thisNamespace:Customer>
                        <cust:Name>Bob Smith</cust:Name>
                        <cust:acctNumber>02789</cust:acctNumber>
                                     </thisNamespace:Customer>
            </thisNamespace:StatementRequest>
      </SOAP-ENV:Body>
   </SOAP-ENV:Envelope>


  The code has been modified to result in the request envelope:

  <SOAP-ENV:Envelope
       xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"
       xmlns:thisNamespace ="http://thisnnamespace.net/"
      xmlns:cust ="http://customer.net/"
       xmlns:xsd="http://www.w3.org/2001/XMLSchema"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
      <SOAP-ENV:Body>
            <thisNamespace:StatementRequest>
                  <cust:Customer>
                        <cust:Name>Bob Smith</cust:Name>
                        <cust:acctNumber>02789</cust:acctNumber>
                                     </cust:Customer>
            </thisNamespace:StatementRequest>
      </SOAP-ENV:Body>
  </SOAP-ENV:Envelope>
 
  Since the Customer complex type is imported from the "http://customer.net/" namespace, the prefix for cust:
  should  be used to qualify it.

(8.0.1) web services XML directory

The default resource qualifier is <varoot>/xml where <varoot> is the installation directory. A problem occurs on Unix if a web service attempts to write into this directory since normally this directory can only be written into by the root user. The solution is to change permission on the /xml directory and its content files to 766.

The same problem ocurs on Windows 7 and Vista with UAC active.


Seaside

(8.5.1) Level of code

Seaside 3.0.6+ / Grease 1.0.6 level of function is delivered in this release (see the Notes section of each Configuration Map for the exact package versions). This includes the following:

The 

(8.0.1) Seaside Support Documentation

Seaside support is documented in Dynamic Web development with Seaside.

(8.0.1) Limitations:


XML

XML code page conversion (unsupported encodings)

The XML parser automatically performs code page conversion before attempting to parse an XML stream. Many code pages are handled seamlessly using the default code page conversion routine of the runtime operating system. However, there are some character encodings that cannot be converted. Unsupported code page conversions cause walkbacks at execution time.

The following code pages are not supported:

The VA Smalltalk XML support attempts to map XML character set encodings to valid code pages. The default mappings can be overridden using the API shown in the following example:

 
    AbtXmlStreamConverter mapEncoding: 'UTF-8' toCodePage:  65001.

VA Smalltalk uses the code page conversion support APIs that are built in to each of the supported platforms. Therefore, code page mappings may be different for different operating systems. If you encounter a debugger with the following message it is likely that you have encountered an unmapped or mismapped encoding.

 
    Abt.Nls.160.e: Conversion from code page <sourceCodePage> to code page <targetCodePage> is not
    supported.
