NonStop Server for Java Programmer's Reference (NSJ 4.2+)

type the following command at the OSS prompt set the JREHOME shell variable:

$export JREHOME=/test_dir/java/jre

3. Set the PATH Environment Variable.

Add the directory where the NonStop Server for Java 4 executable file is installed to your

PATH environment variable.

For the standard installation, type the following command at the OSS prompt:

$export PATH=/usr/tandem/java/bin:$PATH

If the NonStop Server for Java 4 is installed in a nonstandard location, /test_dir, type:

$export PATH=/test_dir/java/bin:$PATH

4. Check Your Path Settings.

Optionally, you can check whether your path is set correctly by using the whence command.

Type:

$whence -v java

This command should display the fully qualified name of the java executable found in your

path. If no Java executable is found, the command displays the message, "java not found".

5. Compile the Java Source Code by Using the javac Tool.

Ensure you have performed step 3 so that javac is in your current path.a.

At the OSS prompt, change the directory (cd command) to where your Java source file is

stored.

Compile the Java source code by using the Java compiler, javac, which is part of the

installed NonStop Server for Java 4 product. Type the following command at the OSS

prompt:

$javac HelloWorld.java

If compilation is successful, the compiler produces a Java class file called

HelloWorld.class. Once you have the class file, your program is ready to run.

Check to see that the HelloWorld.class file has been created by typing:

$ls -l HelloWorld.class

If the file is not present or if you received an error message, check for typographical

errors in your source code. Fix them, and perform sub-steps c and d again until you have

a class file.
