EJB 3.0 RC3 Gives me messageName errrors

[dornus]

I have just upgraded my 4.0.2 to use EJB3RC3.

In doing so, I now get the following errors with my code.

 @Resource(name = "Blah" )
 QueueConnectionFactory factory;

You did not specify a
@Resource.mappedName() on 'myClass' and there is no binding for that enc name in XML

so, the logical thing to do would be this.

 @Resource(name = "Blah" mappedName="blah2" )
 QueueConnectionFactory factory;

However, this gives me a syntax error. I don't know how to put 2 properties (name,mappedName) within the resource tag.

so I did this

 @Resource(mappedName="blah2" )
 QueueConnectionFactory factory;

and obviously it gave me jndi lookup errors.

I cannot find any documentation on what mappedName is and how to use it. Is it a name I give it, or is it some specific name like javax.Queue?

Can anyone post an example of what it is and how to properly use it?

[instinct]

have you tried seperating the two parameters with a comma ?

@Resource(name = "Blah", mappedName="blah2" )

don't know if this makes sense but it would be syntactically right

[dornus]

Yep, I tried a couple of different variations.

queues and topics are under:

queue/MyQueue
topic/MyTopic

@Resource(mappedName="queue/MyQueue")

sorry for the confusion.

[dornus]

I'm still confused. Does it work like this:

@Resource(mappedName="queue/MyQueue")
QueueConnectionFactory factory;

or like this

 @Resource(name="ConnectionFactory" )
 QueueConnectionFactory factory;

 @Resource(mappedName="queue/MyQueue")
 Queue queue;

[dornus]

Now when I compile it looks like I am also missing a value for @Management

What should that be?

@Management
public interface MyClass{
...
}

[dornus]

Could you please convert this example to work under EJBRC3?

 @Resource(name = "ConnectionFactory" )
 QueueConnectionFactory factory;

 private void someMethod(){
 QueueConnection cnn = null;
 QueueSession sess = null;
 QueueSender sender = null;

 try {
 InitialContext ctx = new InitialContext();
 Queue queue = (Queue) ctx.lookup("queue/MyQueue");
 ...
 }

 }

[bill.burke]

@Resource(mappedName="ConnectionFactory")
QueueConnectionFactory factory;

@Resource(mappedName="queue/MyQueue")
Queue queue;

[dornus]

Excellent that works!

I think where I got confused was a few posts up where it said that all mappedName="" had to start with queue or topic. But for QueueConnectionFactory it is not the case.


Thanks!
