Problem with methods returning an attachment

[Bernhard Pauler]

I have posted this question already in the JBossWS forum at jboss.com but haven't got any reply ... ( http://www.jboss.com/index.html?module=bb&op=viewtopic&t=119030 )

Some methods of my web service should return an attachment.

I start with a handwritten WSDL file and generate the necessary artifacts and descriptors using JAX-RPC tools.

There are no warning or error messages at deploy time.

An error occurs after invoking the method:

16:27:34,485 ERROR [SOAPFaultHelperJAXRPC] SOAP request exception org.jboss.ws.WSException: Operation does not have a return value: {http://myservice.mycompany.com/myservice}getTemplate

I can't figure out why JBoss behaves that way - can somebody help me with this?

Thanks,

Bernhard
