Hi All.
Can anybody help me with the next issue I have?
I try to do next:
1. I need to intercept exception inside ESB service, analyze exception, add some
parameter to message body (e.g. my own error code, error description)
2. I need to have access for that parameters in the BPM, after current node forward me to
another, for the reason exception transition.
The main problem is. It seems after exception BPM doesn't copy main body and
parameters from esb to bpm's variables.... and maybe completely forget about output
message.
This is some chunks of my esb and bpm descriptions files:
-------------------------bpm---------------------------------
<node name="Save">
<action
class="org.jboss.soa.esb.services.jbpm.actionhandlers.EsbActionHandler">
<esbCategoryName>
SampleCategory
</esbCategoryName>
<esbServiceName>
SaveData
</esbServiceName>
<bpmToEsbVars>
<mapping bpm="domainData" esb="domainData"/>
</bpmToEsbVars>
<esbToBpmVars>
<mapping esb="ERROR" bpm="ERROR_DESC"/>
<mapping esb="ERROR_CODE" bpm="ERROR_CODE"/>
</esbToBpmVars>
<exceptionTransition>exception</exceptionTransition>
</action>
<transition name="ok" to="Done"/>
<transition name="exception" to="Error"/>
</node>
<node name="Error">
<event type="node-enter">
<script>
<expression>
java.lang.System.err.println(" ERROR ");
</expression>
</script>
<action
class="org.jboss.soa.esb.services.jbpm.actionhandlers.EsbActionHandler">
<esbCategoryName>SampleCategory</esbCategoryName>
<esbServiceName>CheckErrorDetails</esbServiceName>
<bpmToEsbVars>
<mapping bpm="ERROR_DESC" esb="ERROR"/>
<mapping bpm="ERROR_CODE" esb="ERROR_CODE"/>
</bpmToEsbVars>
</action>
</event>
<transition name="to Error Save" to="ErrorSave"/>
</node>
-------------------------bpm----------------------------------------------------------esb---------------------------------
<service category="SampleCategory" name="SaveData">
<actions>
<action name="interceptor1"
class="edu.ggu.integration.actions.ExceptionHandlingAction">
<property name="exceptionMethod"
value="catchesException" />
<property name="code" value="101" />
<property name="message" value="message3"
/>
</action>
<action class="edu.ggu.integration.actions.SaveData"
name="saveContact">
<property name="variables">
.........
</property>
</action>
<action name="interceptor2"
class="edu.ggu.integration.actions.ExceptionHandlingAction">
<property name="exceptionMethod"
value="catchesException" />
<property name="code" value="102" />
<property name="message" value="message3"
/>
</action>
<action name="soapui-client-action"
class="org.jboss.soa.esb.actions.soap.SOAPClient">
<property name="wsdl"
value="..........................." />
<property name="responseAsOgnlMap" value="true"
/>
<property name="SOAPAction" value="Action"/>
<property name="LoggingMessages" value="true"
/>
</action>
</actions>
</service>
Each of "interceptor<N>" actions handle possible exception, add ERROR and
ERRO_CODE to the message.
PBM show me error:
[org.jbpm.graph.def.GraphElement] (JbpmJobExector:127.0.1.1:1) action threw exception:
unable to resolve property: ERROR
if there was an error in the "Save" node. And really, when, I try to see output
message (without mapping in the "ERROR" node) I cannot see my parameters in the
message.
BTW.The main idea is: I need to know what happened, and get access for stacktrace inside
another BPM node and another ESB service after exception.
P.S. Thanks in advance for help
