Window > Preferences>Xdoclet

Look at screen shot.

1. I look for location of xdoclet-1.2.3.jar (using search) .
Selecting version 1.2.3. Setting home folder path from search...
2. xdoclet-1.1.jar not included in studio (can't find it with search in studio folder).

When i try to make something with EJB project - it says that "Annotation provider definition is not valid, please check the preferences."

After few open-close Preferences, this error message disappear, but nothing still works.
