I used jboss-4.2.1.GA (which includes jbossws-1.2.1.GA) only tweaked for .NET Webservices (restrictedUserAgents="^.*MS Web Services Client Protocol .*$" n jboss-web.deployer/server.xml). Everything works lik charm here. Then i installed jbossws-2.0.0.GA. The log file showed no problems, but i couldn't authenticate to the webservice any longer. A SLSB webservice without authenticaton works without a problem. The client is a simple C# .NET 2.0 program.
