JAX-RS Client Connection Timeout Handling in Interceptor - cxf

Question

I have added the below config in my client application context xml:
<bean id="customTimeoutConfigInterceptor" class="com.hs18.inventory.client.interceptor.CustomTimeoutConfigInterceptor" />
<jaxrs:client id="inventoryServiceEndPoint"
address="http://$INVENTORY_CLIENT{inventory.api.host}:$INVENTORY_CLIENT{inventory.api.port}/api/1"
serviceClass="com.inventory.common.InventoryService"
inheritHeaders="true">
<jaxrs:providers>
<ref bean="hs18ResponseExceptionMapper" />
</jaxrs:providers>
<jaxrs:inFaultInterceptors>
<ref bean="customTimeoutConfigInterceptor" />
</jaxrs:inFaultInterceptors>
</jaxrs:client>
when the client times out i want to put the request in a message queue, I am trying this through CustomTimeoutConfigInterceptor class. But the handleMessage method is never invoked. Below is the code.
public class CustomTimeoutConfigInterceptor extends AbstractPhaseInterceptor<Message> {
#Resource
InventoryServiceAsync inventoryServiceAsync;
public CustomTimeoutConfigInterceptor() {
super(Phase.PREPARE_SEND_ENDING);
}
#Override
public void handleMessage(Message message) throws Fault {
Exception exception = message.getContent(Exception.class);
if(exception.getMessage().equals("Connection Refused")){
if(message.getContent(List.class) != null && !message.getContent(List.class).isEmpty()){
Object request = message.getContent(List.class).get(0);
if(request.getClass().getAnnotation(Command.class) != null){
inventoryServiceAsync.sendCommand((ICommand)request);
}
}
}
}
}

Is this for a JAX-RS client reaching out to some external endpoint? If so, I can tell a couple of things:
The connection timeout or client timeout happen on the "out" part of the communications stack, so you may want to set it on the outFaultInterceptors instead
From the previous point follows that the phase set on your interceptor constructor also needs to be updated, I have tried setting it to Phase.POST_STREAM and seems to be working.
