[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:


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:

11:33:23,890 ERROR [STDERR] Jul 18, 2006 11:33:23 AM com.rtn.ejb.AttachmentHandler handleResponse
INFO: Message content:
Content-Type: text/xml; charset=UTF-8

Content-Transfer-Encoding: binary
Content-Id: <result=realData.xml at rtn.com>

<?xml version="1.0" encoding="UTF-8"?>
<!-- test example of an XML attachment -->
hello, world!


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.
