I am not familiar with JBoss, but many app servers specify the Java home in
their own config files and completely disregard $JAVA_HOME.

Vector of vectors?? What is the base type of the "inner" vector?

The "new" type has to have compatible genericity with the variable type. You
did not provide a base type in the "new" expression.

The variable type says that each Vector element is itself a Vector, but says
nothing about the base type of that element's Vector. Are you trying to do
something similar to:
  Vector <Vector <BaseType>> tmpv1 ...?

You might have to modify a JBoss configuration file.

That done, you should fix line 2 anyway:

Vector <BaseType> tmpv1 = new Vector <BaseType> ();

("BaseType" itself can be a generic class, e.g., another layer of
"Collection<T>".)

Bear in mind that Vector methods are synchronized. If this is overkill for
you, consider using java.util.ArrayList instead.

In most cases, the variable type should be the interface supertype of the
actual type.

List <BaseType> var = new ArrayList <BaseType> ();
  or
List <BaseType> var = new Vector <BaseType> ();

Now you can change the implementation without breaking the code that depends
on "var".

List <BaseType> var = new TreeList <BaseType> ();

Homework: What drives the choice of one implementation over another?
Hint: Read the API Javadocs for each implementation.

I would avoid using scriptlets at all, if possible. I'd look into using
some sort of MVC architecture where your controller is in Java code,
and your view is jsp. The problem could very well be that JBoss uses a
language level < 1.5 to compile JSP's.

JBoss (usually) uses Tomcat as web container.

Newer versions of Tomcat uses Eclipse Java compiler
not the SUN Java compiler from the JDK.

The Eclipse Java compiler in Tomcat 5.5 does not
support Java 1.5 generics.

My guess is that this is what is bothering you.
