Re: [xfire-user] Parsing SOAP from a JMS Queue

[Franz Garsombke]

I was actually thinking of blogging on this whole experience but adding it to the website would be even better. All of 2 people probably read my 'once every 6 months blog' :).

Thank you for the excellent suggestion of writing my own transport. I think I made it much harder than I had to. Basically I had one pass through service which had a custom invoker. In the custom invoker constructor I would pass the Object graph and then just use this as the return value for the invoke method. XFire would create the correct SOAP request with one 'extra' document wrapper. I would then remove that and have a SOAP request with the correct SOAP body. Kludgy? Yes. Does it work? Yes.

I will create a custom transport and let you know how that goes. I should be able to add my results (code, explanation, etc.) on the website in the next day or two. We are using this solution on a very large integration project with WebLogic as our application server and Tibco EMS as our message bus. Our preferred messaging wrapper is SOAP.

How is the website edited?

Take care.

Heres what I would probably do:

1. Create a service interface for my outbound request:

public interface Sender {
public void send(MyDataType data);
}

2. Create a client
Service service = new XmlBeansServiceFactory().create(Sender.class)
XFireProxyFactory xpf = new XFireProxyFactory();
Sender sender = (Sender) xpf.create(service, "jms://Queue")

3. Send the data:
sender.send(myData);

Now, if you don't use want to use the XFire JMS transport you can
quickly write your own. Really its probably as simple as extending
AbstractTransport and creating your send method. (Also don't forget to
do SoapTransportHelper.createSoapTransport(this) in the constructor. It
adds helper handlers for SOAP to the transport).

You can tell your client about the transport:
Sender sender = (Sender) xpf.create(service, new MyJMSTransport(),
"jms://Queue")

That help?

Also, if you were motivated enough to write up your experiences on how
to do this, I'm sure there are many around who would appreciate it! The
website can be easily edited and this would make a really cool addition
to the user manual IMO.
