I'm just on my way to Munich. I'm giving a talk about Web Service policies and interoperability at OOP 2006 together with Klaus Alfert. It's gonna be fun. We're giving a high level overview on WS-* standards and drilling down into some interop scenarios between .NET 2.0/WSE3, BEA WebLogic Workshop 8.1.5 and Suns JWSDP 1.6.
Preparing this talk and one of the security demos, we both learnt lots about getting, storing and using X.509 test certificates and about the different tools managing them. It's a kind of nightmare, if you try to get the same certificate working on different server platforms. I'll post some more details on my experiences in this area in the next week...
