Java Demos

If you installed the java2v131_02_dev.sw.demos subsystem, then you have some simple examples of how to use JNI, Sun's new Java Native Interface. They illustrate how to code native functions using JNI and create JNI-specific header files using javah. They are under /usr/demos/java in the following directories:

JNI-simple-test

an illustration of "Hello World" using JNI

JNI-big-test

shows how to pass arguments and return values to and from the native world

JNI-invocation-test

shows how to use the Invocation API

Each of these demos comes with a Makefile; typing make will build and run the example program.

These demo directories are owned by the user demos, so you should either login as user demos or copy them to a directory where you have write permission if you want to be able to make changes, recompile, etc.
