[jboss-dev-forums] [Design of JBoss ESB] - Re: Problems with transmitting content from ESB to jBPM via

[andreskusa]

Hi Bernd,

thanks, that helped!

For all who are interested, here are some details of the solution:

The esbToBpmVars are read by jBPM like this

 String esbToBpmXml = toEpr.getAddr().getExtensionValue(Constants.ESB_TO_BPM_VARS_TAG);

So, this variable needs to be set into the EPR of the Call-Object of the header.

And it should contain the XML code of the mappings that I put before into the properties of the jbpmCallback-Action, i.e.:


  | <property name="esbToBpmVars">
  |   <mapping esb="messageContent"	bpm="bpmMessageContent" />
  |   <mapping esb="settingsESB"	bpm="bpmSettingsESB" />
  | </property>	 
  | 

So, the setting of this variable looks finally like that:


  | String esbToBpmVars = "<property name=\"esbToBpmVars\"> ";
  | esbToBpmVars = esbToBpmVars + "<mapping esb=\"messageContent\" bpm=\"bpmMessageContent\" /> ";
  | esbToBpmVars = esbToBpmVars + "<mapping esb=\"settingsESB\"	bpm=\"bpmSettingsESB\" /> ";
  | esbToBpmVars = esbToBpmVars + "</property>	";
  | 
  | PortReference portReference = replyTo.getAddr();
  | portReference.addExtension(Constants.ESB_TO_BPM_VARS_TAG, esbToBpmVars);
  | message.getHeader().getCall().setTo(replyTo);
  |
