[jboss-dev-forums] [Design of JBoss jBPM] - Problem in deploying the processDefinition.xml

[anu123suya]

I am a newbie to JBPM 3.1.2 and need to deploy a simple processdefinition to the Jboss app server and hsql db.

Took the jbpm.sar and the db script from the starter kit.

I tried the following deployment ways

1. When tried to deploy the process definition from eclipse, I got a succes msg. but the Database tables for this process is not updated.

2. When I tried to deploy it programmaticaly with the following code,

JbpmConfiguration jbpmConfig = JbpmConfiguration.getInstance();
JbpmContext jbpmContext = jbpmConfig.createJbpmContext(); 
ProcessDefinition processDefinition = ProcessDefinition.parseXmlResource("META-INF/processdefinition.xml"); 
jbpmContext.deployProcessDefinition(processDefinition); 


getting the following exception. 

Can anyone suggest me the steps to deploy the processdefinition.xml and invocation of the process.

Thanks
