Problem with MTOM example

[emiedes]

Hi,
I tried to run the mtom example (from Spring-WS 1.5.7, with JBoss 5.0.1 and Sun's JDK 1.6.0_10) and I am getting an exception in both the client and the server sides.

In the client side I get an org.springframework.ws.client.WebServiceTransportE xception that points out an "internal server error" (500).

In the JBoss log I get this:

I used Wireshark to see the messages sent back and forth:

The request is something like this (I find it correct, isn't it?):

The response I see with Wireshark is something like this:

First of all I thought the problem is due to the difference between the CID used in the SOAP request:
cid:6af0843d-fd6b-4c4d-90be-e1ed283cab41%40www.springframework.org
and the one used in the attachment:
<6af0843d-fd6b-4c4d-90be-e1ed283cab41@www.springframework.org>
but, according to some RFC (http://www.ietf.org/rfc/rfc2111.txt) that is ok.

I've been wandering around in the forum (and some Google) and I haven't found anything like this.
Moreover, I found that XOPContext class in several places in the JBoss installation:
server/default/deployers/jbossws.deployer/jbossws-native-core.jar
server/all/deployers/jbossws.deployer/jbossws-native-core.jar
server/standard/deployers/jbossws.deployer/jbossws-native-core.jar
client/jbossws-native-core.jar

I can also say that I algo got the exception in that XOPContext.getAttachmentByCID in another example I tried before (something I did using the MTOM example as a basis). First, I thought I was doing something wrong but now I don't know what to think of this.

Any idea?

Thanks!
