It seems to me that you have not compiled your source code - you wrote it
directly to the class file.
The first thing you should do is
a) Write your source code to a file named "com/mycompany/HelloWorld.java"
b) Remove syntactic errors from the source code (it should start with
"public class HelloWorld" instead of "public HelloWorld"
c) Compile your source code to a class file using "javac
com/mycompany/HellowWorld.java"
d) Pack your class file into a jar file (don't foreget to include the
complete relative path com/mycompany/HelloWorld.class)
e) Install the jar file into correctly configured postgresql server

Tip: Try to run your HelloWorld examples without pljava first, using simple
java runtime. When you understand how it works, try to integrate it with
postgres.
