Well I had to admit defeat with my web services problem. I tried a few more things this morning which occcurred to me overnight but no luck. So instead I am going to do the work in a JBoss application. What's especially galling is that it took a grand total of ten minutes to build and deploy a test client for the web services using MyEclipse and JBoss. It's pretty much unforgivable that Domino can't do this stuff out of the box. I am guessing it will work in ND8 but unfortunately that's just too late for me.
