OOJNI Add-in .NET for VC7.1 - Object-Oriented JNI Advanced Add-In is a tool developed for MS Visual Studio. It generates C++ code (OOJNI classes) and managed code (OOJNI for .NET classes) in MCPP, C#, J#, VB for java byte code selected and includes it into the active project. It also makes JNI implementation of Java class native methods. At the same time OOJNI Add-In makes all project setting for using, compiling and running the code generated.

Developer uses OOJNI classes as regular C++/MCPP/C#/J#/VB classes. Each OOJNI class wraps low-level JNI code to accesses to Java Class fields and methods. All data type conversions are hidden from Developer. Each java object reference encapsulated into special OOJNI class – Java Reference Wrapper, which makes a shallow copy of the java object reference in different OOJNI classes. This approach makes possible to reduce a number of java references used in JNI code.
