Hello, Has anyone tried to have a web service with mtom *and* ws security activated? I did some tests with a web service as an ejb3 stateless bean and a Java standalone client (using the client parts of JbossWS): mtom only works, ws-security only works. But when I enable both, I get an exception: javax.xml.ws.soap.SOAPFaultException: Endpoint {http://foo.org/mtom}ServiceImpl does not contain operation meta data for: {http://www.w3.org/2001/04/xmlenc#}EncryptedData If I inspect the network communication, the client seems to use ws-security and put all the data as an encrypted envelope. There is no binary attachment anymore. On the server side, it seems that ws-security cannot be enabled with mtom, as the exception suggests. Maybe the two standards are not compatible to work together. I didn't found any information that says: no, no, no don't use mtom with ws-security. Thanks in advance for any enlightenment, Let me know if my description is not clear enough, best regards, :oD.
