hey again peter, and thanks! we decided to go with the 4.2.2 for now and migrate when the 5 is more stable and documented, thanks for reassuring us. we still dont know which version of EJB we want to use, but we'll probably go with the EJB3. the "we" that i use every once and a while refers to 2 people (me and my partner) and since the server which runs the XP is for development purposes i really don't think that we'll exceed to 10 connections limit... the only reason we are using XP is that it already came with the computer we're using for a server... if and when we'll need more connections we'll probably have more money to invent in this whole thing so we'll upgrade everything... and we'll probably wont stay with a microsoft os since we dont intend to use any microsoft product for the server... thanks.
