A Simple VME Application

Follow the steps below to create, compile, and run a simple Java program to read and write a VME register.

Create the Java Source file

Using your favorite editor, create the file VMETest.java or just save the link using a browser. This program will write then read address offset 0 of a module specified on the command line.

Compile the Source File

First, set up the Java Development Kit and the FISION VME library. On the B0 unix cluster, issue the commands:

    setup jdk 1.1.1
    setup fision

Then, compile the program:

    javac VMETest.java

When compilation is complete, the file VMETest.class will appear in the current directory.

Run the Program

To run the program, issue the command:

    java VMETest b0ts01 18

(Substitute a valid MVME-162 node name and occupied VME slot for the last two parameters).
