How To Use Third-Party Packages from Visual J++ 6.0

This article illustrates how to access third-party packages from within Visual J++ 6.0.

NOTE: The Microsoft virtual machine (Microsoft VM), does not support JDK versions later than JDK 1.1.4. Packages must be found within or be compatible with the JDK version 1.1.4.

The following steps illustrate how to access a third-party package:

1. If you have a Java Archived Redistribution format (JAR) file that compression is one or less proceed to step two. Otherwise, uncompress the third-party JAR file and re-zip it without compression, creating a file such as Mypackage.zip.
2. Place the JAR file or new zip file in the following directory:

   C:\%windir%\java\classes
   					

3. Modify the CLASSPATH in the registry. Run RegEdit.exe and locate the following key:

   HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Java VM
   						

   and modify the CLASSPATH string to include the JAR file or new zipped file. For example:

   C:\%windir%\java\classes\mypackage.zip
   						

   needs to be added to the end of the string, and don't forget the semi-colon separating each entry in the string. Also note the "." at the end of the CLASSPATH string.

You should now be able to access and use the third-party classes from within Visual J++ 6.0.

The following is a list Packages that have been known to be accessed with Visual J++ area:

• BEA Jolt 1.1
• JClass
• JGL
• JFC/Swing

Currently the Microsoft Virtual Machine only supports up to JDK 1.1.4 versions.
