Camel does not stop if I design the route like this (add a try/catch block
in the finally) :
<camel:route errorHandlerRef="txErrorHandler">
<camel:from ref="directRequestEndpoint" />
<camel:transacted ref="PROPAGATION_REQUIRED" />
<camel:doTry>
<!-- Call the requestService to save the request -->
<camel:bean ref="serviceHelper" method="createRequest" />
<!-- <camel:bean ref="serviceHelper" method="generateError"
/> -->
<camel:to ref="queueRequestEndpoint" />
<camel:doCatch>
<camel:exception>com.xpectis.x3s.exception.X3SException</camel:exception>
<camel:bean ref="serviceHelper"
method="processException" />
<camel:to ref="queueReportingEndpoint" />
</camel:doCatch>
</camel:doTry>
<camel:doFinally>
<camel:doTry>
<camel:bean ref="serviceHelper" method="generateError"
/>
</camel:doTry>
<camel:doCatch>
<camel:exception>com.xpectis.x3s.exception.X3SException</camel:exception>
<camel:to
uri="log:x3slog?level=DEBUG&multiline=true" />
<camel:rollback message="Exception occur" />
</camel:doCatch>
</camel:doFinally>
</camel:route>
