Java Development Tools

When i try to run an application that uses ADF BC i get an error telling me the bc4j.xcfg was not found.
When i open my AppModule and click the bc4j.xcfg link it opens. When i look at the path it stored in, it is different from the path the error says.
It's something like this:

Configuration file /be/something/model/common/bc4j.xcfg is not found in the classpath
but my appModule opens the bc4j.xcfg in a different folder:
/be/something/utility/common/bc4j.xcfg

It's a fact i modified the project and managed the packages a bit but i always used the refactor menu of jdeveloper in order to move or rename files.
It appears that something has failed while moving/changing name.

I looked inside my project to look for references for bc4j.xcfg but i can't find any so i can't see were to change the directory he needs to look for the bc4j file.
How do i fix my project?
