Thanks for the immediate reply, I tried the following:
Code:
JbpmTemplate template = (JbpmTemplate) ctx.getBean("jbpmTemplate");
ProcessDefinition def = template.getJbpmConfiguration().createJbpmContext().getGraphSession().findLatestProcessDefinition("process1");
template.setProcessDefinition(def);
template.execute(new JbpmCallback() {
public Object doInJbpm(JbpmContext context) {
ProcessInstance inst = context.newProcessInstanceForUpdate("process1");
inst.signal();
context.save(inst);
// dummy return
return null;
}
})
which gives me the following exception:
Code:

here is my spring config
Code:
<bean id="jbpmConfig" class="org.blah.blah.jbpm.CustomLocalJbpmConfigurationFactoryBean">
<!-- pass in existing sessionFactory -->
<property name="sessionFactory" ref="jbpmSessionFactory"/>
<property name="configuration" value="org/blah/blah/jbpm/jbpm.cfg.xml"/>
</bean>
<bean id="jbpmTemplate" class="org.springmodules.workflow.jbpm31.JbpmTemplate">
<constructor-arg index="0" ref="jbpmConfig"/>
</bean>
however, this works like a charm for me:
Code:
JbpmConfiguration config = (JbpmConfiguration) ctx.getBean("jbpmConfig");
JbpmContext context = config.createJbpmContext();
ProcessDefinition def = context.getGraphSession().findLatestProcessDefinition("process1");
ProcessInstance in = def.createProcessInstance();
ContextInstance cn = in.getContextInstance();
List l = new ArrayList();
l.add("batman");
l.add("joker");
cn.setVariable("list", l);
in.signal();
context.save(in);
context.close();
I am bypassing the jbpm template altogether, I can use the above solution for now, although would love to get the jbpm template working.
Thanks,
meeru
Redeploy issue!
