HI,

I am using jbpm 4.3 in my web application. Whenever I try to run the method deploy, that is actually using repository service to deploy the resource, it gives the following exception :

javax.servlet.ServletException: Servlet.init() for servlet MainServlet threw exception
 org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:117)

This has something to do with the jars i am using but I have searched java forums for this exception and could not find anything. SO finally I posted this question here so if any one who came across could help.
