Hello,everyone

Im a JBPM newbie, I want to set up a project struts2+springmodule jbpm+hibernate+oracle and run a jbpm helloworld. my configuration is as below:

I get error as below when app startup :

org.jbpm.JbpmException: couldn't find process definition 'helloworld'
	at org.jbpm.db.GraphSession.findLatestProcessDefinition(GraphSession.java:158)
	at org.jbpm.db.GraphSession.deployProcessDefinition(GraphSession.java:67)
	at org.jbpm.JbpmContext.deployProcessDefinition(JbpmContext.java:173)

why does it queries the database for the latest version of a process definition with the given name? why not use xml file?  thanks a lot!
