[jira] [Updated] (SYNAPSE-1108) ProxyServiceMessageReceiver
mediates message without default fault sequence
[ https://issues.apache.org/jira/browse/SYNAPSE-1108?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Joseph Caristi updated SYNAPSE-1108:
------------------------------------
Description:
With Synapse deployed as a war, we have defined the "main" and "fault" sequences in synapse.xml. The main sequence uses the xquery mediator to format a response. If we introduce an error in the xquery definition, the xquery mediator fails, but the default "fault" sequence is not called. This is because when the following code from ProxyServiceMessageReceiver executes, the Synapse MessageContext fault stack is empty:
{code:java}
} else if (proxy.getTargetInLineInSequence() != null) {
traceOrDebug(traceOn, "Using the anonymous " +
"in-sequence of the proxy service for mediation");
inSequenceResult = proxy.getTargetInLineInSequence().mediate(synCtx);
}{code}
If we change the code to the following, it works:
{code:java}
} else if (proxy.getTargetInLineInSequence() != null) {
traceOrDebug(traceOn, "Using the anonymous " +
"in-sequence of the proxy service for mediation");
if (synCtx.getFaultStack().isEmpty()) {
// set default fault handler
synCtx.pushFaultHandler(new MediatorFaultHandler(synCtx.getFaultSequence()));
}
inSequenceResult = proxy.getTargetInLineInSequence().mediate(synCtx);
}{code}
