Hi all,
I have an application deployed into JBoss 4.0, everytime when i redeploy the application, it will crashed. But when i restart my JBoss, the application will be working again.

The exception thrown out when i re-deploy the application :
11:05:55,440 WARN [MapperListener] Error registering Context jboss.web:J2EEApplication=none,J2EEServer=none,j2eeType=WebModule,name=//localhost/finet
ReflectionException: Cannot find method findMappingObject with this signature Cause: java.lang.NoSuchMethodException: org.apache.commons.modeler.BaseModelMBean.findMappingObject()
at org.apache.commons.modeler.BaseModelMBean.invoke(BaseModelMBean.java:490)

Fyi, the application is working properly until I include jbpm as the Business Process Workflow Engine.

Can anyone give me some hints what's wrong here?

thanks.
