RE: jde-usages and Java 1.5 Generics Syntax

Thanks Suraj.
 
The latest jde-usages and ecb in cvs completely solved the problem.
 
One minor thing I found was that the jde-usages integration with ecb does
not work.  After loading the ecb integration from the jde-usages menu,
selecting a usages item on an ecb menu results in a void symbol error for
tree-node-get-data.  I fixed this by modifying jde-usages-ecb.el and
changed all occurences of "tree-node-get-data" to "tree-node->data".  I'm
no lisp programmer and don't know what the "->" operator is.  (Is it some
sort of associative operator?)  I just followed an example in the ecb
documentation and got lucky.
 
Thanks again.

This is fixed in jde-usages CVS. (Yes, I know I should push out a new
release soon.)

I think the following defun should be enough to fix the problem, the old
function is based on regexps. We can use semantic instead now. 

(defun jde-parse-get-class-at-point ()
 (mapconcat 'semantic-tag-name (semantic-find-tags-by-class 'type
(semantic-find-tag-by-overlay (point))) "."))

JDE and jde-usages are both great packages.  Thanks Paul, Suraj, et al,
for all your hard work on these.

jde-usages seems to work with a great deal of the Java 1.5 generics
syntax.  For example, if the cursor is on the word "get" in the following
program, I can use "JDEpi->jde-usages->Usages/Callers for->Method or field
definition at point" to successfully display the caller tree for that 
method.

    package test;

    import java.util.Vector;

    public class Test {

        private Vector<Integer> get() { return new Vector<Integer>(); }

        private void run() { Vector<Integer> foo = get(); } 

        public static void main(String[] args) {
            Test test = new Test();
            test.run();
        }
    }

However, if I add a type to the class definition so that line reads:

    public class Test<Integer> {

I cannot display the caller tree for the get method.  Instead, I get the
message:

    Wrong type argument: stringp, nil

The contents of the *Backtrace* buffer are included below. 

Is there anything I can do to persuade jde-usages (or semantic, or
whatever) to work with this syntax?

Thanks in advance for any info.
