ContentBasedRouter does not work!

[viniciuscarvalho]

JBoss ESB version: 4.2.1.GA
Hello there! I was trying to get the CBR to work, and after many failures I decided to look at the code... :(

Well, It's no surprise my rules do not find any destination. It depends on a property named object-path. Here's the stack call for the CBR :

 public Message process(Message message) throws ActionProcessingException
 {
 try {
 List<Service> outgoingDestinations = executeRules(message);

Ok, so it tries to get the outgoingDestinations at this point. No problem so far...

 protected List<Service> executeRules(Message message)
 throws MessageRouterException
 {
 List<Service> outgoingDestinations = new ArrayList<Service>();
 try {
 List<Object> objectList = _mapper.createObjectList(message,
 _messagePathList);

Now the above code is the source of the problems, as the property _messagePathList, is initialized with an empty arrayList (dunno why does CBR needs that, isnt that something for the BusinessRuleService???)

So the next piece of code shows that with an empty _messageList, I get an empty destinations, so, nothing can be found.

 public List<Object> createObjectList (Message message,List<String> messageObjectPathList)
 throws ObjectMappingException
 {
 List<Object> objectList = new ArrayList<Object>();
 if (messageObjectPathList!=null) {
 for (String messageObjectPath: messageObjectPathList)
 {
 Object value = getObjectFromMessage(message, messageObjectPath);
 if (value==null) {
 logger.warn("The value of " + messageObjectPath + " is null");
 } else {
 if (value instanceof Collection) {
 Collection valuesList = (Collection) value;
 for (Object object : valuesList) {
 objectList.add(object);
 }
 } else if (value instanceof Map) {
 Map valuesMap = (Map) value;
 for (Object object : valuesMap.entrySet()) {
 objectList.add(object);
 }
 } else {
 objectList.add(value);
 }
 }
 }
 }
 return objectList;
 }

I was kinda confused where to post (here or developer forum). Just would like to know if I need to add the objec-path, and if so, the docs should be modified. CBR is a crucial piece of software in our project :)

Can you check out i.e. the quickstarts fun_cbr or simple_cbr? The destinations are mapped with

<property name="destinations">
 <route-to destination-name="blue" service-category="BlueTeam" service-name="GoBlue" />
 <route-to destination-name="red" service-category="RedTeam" service-name="GoRed" />
 <route-to destination-name="green" service-category="GreenTeam" service-name="GoGreen" />
 </property>

Object-paths are used to transfer objects from the message to the rules
engine.

Hope this helps,

Yes Kurt you are right! It was my mistake sorry. What I'm doing is creating a webservice that will put inside the JBossMessage the contents of its message payload (not the soap envelope, Im using @WebServiceProvider with Payload type). Inside the DSLHelper it looks for the payload of the body, and that is only an empty envelope. I just need to figure how to set the payload not he body.
Im using message.getBody().add(byteArrayFromInputSource);
