No, you don't need to jar them. Have you read the IDL manual about how to access
Java objects? Some of the examples there access individual class files.

The problem you have there is that you have not named your class file correctly.
The classloader does not want your java source file. Further, the classloader
locates classes by package name, and '.' is the separator for packages within
the package hierarchy. What the classloader will be looking for in your example
is a file called 'HelloWorld\java.class'.

If your java class in not part of a package then you should include the
directory in which HelloWorld.class resides in the CLASSPATH and specify the
class 'HelloWorld' in the obj_new.

If your class is part of package then you need to include the base directory of
package hierarchy in the CLASSPATH and specify the fully qualified class name
in obj_new.
