Java Demos

If you installed the java_dev.sw.demos subsystem, then you have two demo applets. Follow these links to see them if you are running a web browser with Java support:

In order to view these in the appletviewer, you can do the following:

There are also two simple examples of how to use JNI, Sun's new Java Native Interface. They illustrate how to code native functions to use JNI, as well as how to 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.
