Hi Anurag, You probably don't actually need the extends="..." on the <mapping> in this case. It seems like a lot of people use this unnecessarily, and that sometimes creates problems. It's only really needed when you're doing the equivalent of schema substitution groups, to implement polymorphism. So try taking off the extends and see if that helps.
It's still a nasty bug in the binding compiler that this can occur at all, though. Can you try this using the current JiBX 1.2 beta 1 test release (in the "test" package on the download page https://sourceforge.net/project/showfiles.php?group_id=69358)? I think I'd encountered this issue and fixed it during the development of the 1.2 code, but I'll add in another check for the condition which could cause this for the upcoming beta 2 release. I don't understand your other issue, that "JIBX fails to find classes that are included as dependent projects when I run the compile option". Can you explain this in more detail? - Dennis Dennis M.
