• J-Integra® for .NET fully supports the following platforms and JDKs. For a complete list of supported platforms and JDKs, please see this KB article.
  • Windows Vista
    Note: If installing J-Integra® on Windows Vista, please refer to the following KB article regarding Windows Vista's User Account Control (UAC).
  • Sun Microsystems JDK 6
• Updated Windows Installer to be compatible with Windows Vista.
• Updated Windows Installer to update PATH and CLASSPATH settings as required for J-Integra for .NET usage.
• Fixed bug where GenService 1.1 and 2.0 were not always able to start properly after being installed side-by-side.

Version 2.3 of J-Integra for .NET includes:

• GenService 1.1 and GenService 2.0 are installed side-by-side allowing for true multiple .NET framework support. See the individual tools below for the full details.
• Upgrades to the GenJava and GenNet tools to utilize the side-by-side GenService deployment.
• Small bug fix of passing custom exceptions under.NET Framework 2.0.

Version 2.2 of J-Integra for .NET includes:

• Support for .NET Assembles via Genservice

• Genservice for .NET 2.0 will be installed if .NET Framework 2.0 is present

• J-Integra for .NET runtime updated to reflect latest version of .NET Framework 2.0

Version 2.1 of J-Integra for .NET includes:

• New plug-ins for the Eclipse and Visual Studio IDEs. These provide seamless integration of J-Integra® for .NET functionality with the Eclipse Platform and Visual Studio .NET Integrated Development Environments. The Eclipse plug-in can also be used with IBM's WebSphere® Studio Application Developer IDE.

• Enhancements to the GenJava and GenNet proxy generation tools to provide better auto-detection of the GenService Windows service running locally and auto-selection of the GenService instance. These tools now always have the option for the user to "Enter host Manually" in case GenService cannot be auto-detected.

• Enhancements to the Janetor Configuration Tool to support drag-n-drop. Drop janet.xml files onto Janetor for auto-loading. Adding Local Object or Remote Object classes now gives the option to initialize the new class by copying the settings from the "default" class. Janetor now also displays the version number of the product as part of the "about" information and the runtime checks that the version of the installed license matches the version number of the product.  

• Enhanced formatting of generated XML files (such as the janet.xml configuration file) to add indentation.

• Various enhancements to the GenNet proxy generation tool. These include by default filtering out all java.* & javax.* referenced classes. Also, if a function references a filtered out class it now defaults back to the base Object class and still generates the function instead of removing it from the generated proxies.

• Enhancements to the JanetConfig API (for programmatic creation/modification of janet.xml configuration files) to include the generation of Web Application Archive (WAR) files and license installation / removal.

• Enhancement to the runtime exception reporting to include the inner exception message if an exception is caused by an InnerException.

• Enhancement to allow user configurable URI's for remote .NET objects.

• Support for SOAP message format has been stopped.

• API provided via JanetConfig class to allow programmatic creation/modification of janet.xml configuration files.
• API provided via ILogger interface to enable plug-in of custom logger.
• The GenService installer has been integrated into the main installer. Only one installer now!

Version 1.5 of J-Integra® for .NET includes:

• New caching mechanism provides a huge performance boost, especially noticeable when passing large objects by value. The old mechanism has been retained in case of any compatibility issues. To invoke the old mechanism, include -DJANET_CLASSLOADER_SAFE as a VM parameter.
• Overall update to documentation and examples. J-Integra® for .NET has been made just that much easier to learn and use!
