Hello All,
The below problem occurs during config.buildSessionFactory() on my Linux and OSX boxes, but not on my Windows XP machine. I haven't disounted a difference in configuration, but I definitely can't find any. It worked on the two broken boxes till I did some changes to the relationships (can't recall which ones may have broken it). As you can see, it gets most of the way through the startup as evidenced by the debug logs. But the Configuration looks to be invalid in some strange way that is applicable only to the two unix machines, and not my windows machine. The mapping files were built with Ant 1.6.2 & XDoclet (same version) in all cases.
The debug logs tell which entities are referenced, but not which entity it is currently parsing in the Second Pass logic, so my hands are tied there.
I'm totally stumped here. Any help would be appreciated, even pointing me to some general area I can look at.
Thanks,
Chris
