This evening I attended a webcast about web service interopearability. It was done by Michele Leroux Bustamante of IDesign. The subject was .NET and Bea Weblogic interop and was really interesting. I would like to see now the way to do the same development using Eclipse and deploying the Web service in Weblogic. One of the link to remember about this webcast is: Interop Warriors (such a nice name ;).
