[yogesharora]

Hi,

I have written a standalone java client to access the HelloWorld Sample example of JBPEL 1.1 GA.

Environment Details
=============
JDK - version 1.5
JBPM - version 3.1.4
JBPEL - version 1.1GA
JBoss - version 4.2.2 GA

I am getting the following error:

Please help in finding the solution.

Thanks in advance.
