I've tried a lot to interop between .Net (C#) Client using WSE 3.0 and Jboss 4.2.0 Webservices secured with WSSecurity (Signing and encrypting the webservices). But still it doesn't work... So if anybody has solved this problem, or knows where I can find documentation/help please let me know... WSE 3.0 is no requirement, so any (proprietary) solution is ok as well View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4058208#...
