I have the following codes to parse xml using xerces and I think when I
have line #2
and line #3 I got ExceptionInInitializerError as shown bellow. The
error message
is not very helpful, could anyone give me some ideas why I got this
error?

I also notice when includes all the xerces files in my jar file I had
no error, but if
I let JBuilder's deployment wizard to include only files that are
necessary, I got
the error but the error message does not give me any ideas which files
I am missing.

       else {
         System.out.println("XML Document is valid");
