[jboss-user] [JBossWS] - Problem with SOAP Attachments using EJB 2.1 Web Service Endp
We are trying to build an interoperable web service implemented using an EJB 2.1 service
endpoint. We are starting from WSDL using Sun's tools (wscompile) to generate ties,
etc. The deployment consists only of an ejb-jar file with the appropriate deployment
descriptors. The web service should run on any J2EE 1.4 appserver but I'm having
trouble with JBOSS.
The web service allows for download of arbitrary files; therefore the mime-type of the
response is not known ahead of time.
For maximum interoperability the attachments are sent via document/literal WSDL using
SwaRef/xsd:anyURI according to Sun's example:
https://jax-rpc.dev.java.net/whitepaper/1.1.2/attachments-howto.html
As such, my business method generates and returns a java.net.URI (the Content-ID of the
attachment). Using properties on the EJB MessageContext and SAAJ I am attempting to
create/add the attachment to the SOAP response using a custom handler declared in
webservices.xml
By using SOAPMessage.writeTo( System.out ) the logs appear to show the correct SOAP
message:

However, using a TCP Monitor program it appears that the SOAPMessage isn't getting
onto the wire properly.

Somehow JBOSS is not saving my attachment or it is reverting to the SOAP message as it
existed before the handler got invoked...?
I am disappointed to find very little information regarding this and EJB endpoints on the
Web. I have created a sample ANT script and test case and can provide it for evaluation.
If anyone has implemented something like this please let me know what I'm doing
wrong.
Thanks,
