Hi Werner, I am using Axis 1.1 and the sample programs coming with Axis are working fine for me. In fact, I am able to send and receive attachements in case of anonymous and simple authentication (username and password).
I got stuck only when I try to sign the attachments. I have both axis.jar and activation.jar in my classpath. Please do suggest me any possible solution.

You need to build Axis in the proper way to support attachements (activation.jar, mail.ja must be available). Also note that it is quite tricky to sign Axis message that has attachements because Axis modifes the content of the request just before it puts it on the wire. pls refer to the WSS4J project at Sourceforge, there we solved that problem already.
