[jboss-user] [JBoss jBPM] - Error when calling a process from a java class

Hi, I am calling a JBPM process from a java class using the following code: JbpmConfiguration jbpmConfiguration = JbpmConfiguration.parseResource("jbpm.cfg.xml"); //ProcessDefinition processDefinition=ProcessDefinition.parseParResource("D:\jbpm/src/process.examples/simple.par/processdefinition.xml"); ProcessDefinition processDefinition=ProcessDefinition.parseParResource("simple.war/processdefinition.xml"); JbpmContext jbpmContext = jbpmConfiguration.createJbpmContext(); ProcessInstance processInstance=new ProcessInstance(); jbpmContext.deployProcessDefinition(processDefinition); Token token=processInstance.getRootToken(); assertSame(processDefinition.getStartState(), token.getNode()); token.signal(); assertSame(processDefinition.getNode("first"), token.getNode()); token.signal(); assertSame(processDefinition.getNode("end"), token.getNode()); On deploying the WR file I am getting this error in the above java class. description The server encountered an internal error () that prevented it from fulfilling this request. exception org.apache.jasper.JasperException: in is null org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:370) org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:314) org.apache.jasper.servlet.JspServlet.service(JspServlet.java:264) javax.servlet.http.HttpServlet.service(HttpServlet.java:810) org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:81) root cause java.lang.NullPointerException: in is null java.util.zip.ZipInputStream.(ZipInputStream.java:55) org.jbpm.graph.def.ProcessDefinition.parseParResource(ProcessDefinition.java:201) simple.CallProcess.testCallProcess(CallProcess.java:17) org.apache.jsp.CallMethod_jsp._jspService(org.apache.jsp.CallMethod_jsp:58) org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:97) javax.servlet.http.HttpServlet.service(HttpServlet.java:810) org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:322) org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:314) org.apache.jasper.servlet.JspServlet.service(JspServlet.java:264) javax.servlet.http.HttpServlet.service(HttpServlet.java:810) org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:81) Please help me how can i solve this problem? thanks in anticipation.
