I have a simple workflow that am trying to trigger a spring bean for action.

<node name="node2">
<event type="node-enter">
<action name="test" class="org.springmodules.workflow.jbpm31.JbpmHandl erProxy" config-type="bean">
<targetBean>
notifyMessage
</targetBean>
</action>
</event>
<transition to="Assign Draft User"></transition>
</node>

notifyMessage is a class that implements ActionHandler that has a execute method-> for now just prints a message.


I'm unable to understand what am I doing wrong here. Currently on springmodules 0.9 and spring 2.3 jbpm 3.2.8 and using flex for frontend via spring remoting.

If i do not use JbpmHandlerProxy and call the class directly it works fine. I've tried different factory keys

Left factory key blank. Still same error.

My application context bean org.springframework.context.support.ClassPathXmlAp plicationContext is called main-context. I tried this as my factory key.

My jbpm config bean is org.springmodules.workflow.jbpm31.LocalJbpmConfigu rationFactoryBean
is called jbpmConfig. I tried to pass this as my factory key.

Need help.

Still keeps throwing below errors.
