J# applications are not companionable with the Java Virtual Machine (JVM) or the Java 2 platform. J# is referred to as Visual J#.

Visual J# is a set of programming tools that permit developers to make use of the Java programming language to write applications that will run on Microsoft’s. Net runtime platform.

Visual J# also supports the functionality of Visual J++ and Microsoft extensions. For Visual J++ users, Microsoft is say that Visual J# presents a familiar interface and both development systems and project files can be used on the same machine.

The redistributable package is act as the application middleware allows J# programs to run on any computer with the 1.1 .NET Framework already installed.

Applications that require the J# redistributable package are only those that are written in Visual J#. Additional information on J# requirements should be obtained from Microsoft’s Visual J# website earlier than deploying the package to production systems. Considerations should also be recognized for deciding whether to develop in Visual J# versus another .NET language.

The J# redistributable package cannot run programs produced with other Java development tools, such as programs written in the Eclipse or Net Beans IDEs.

For Visual J++ users, Microsoft says that Visual J# presents a recognizable interface and both development systems and project files can be used on the same machine.
