ObjectDB eclipse plugin

Hello, Creating an eclipse plugin from the downloadable objectdb.jar file DOES NOT work in the eclipse OSGi environment (at least that is my experience). Could we have a genuine eclipse plugin from ObjectDB that works? You already have a pluging that integrates Objectdb with BIRT, so it seems it should not be difficult. The downloads could now have both the eclipse plugin as well as the usual jar. Let me know what you think.   Thanks #1 2011-07-14 18:30 Hello, Creating an eclipse plugin from the downloadable objectdb.jar file DOES NOT work in the eclipse OS ...

It seems like that we can't reproduce the problem in smaller use cases with less objects.

Hello, I have an old database file with important data. Over time, I have modified some of the entity classes but did not keep track of the changes. Some fields may have been renamed or removed, some classes may have been renamed or changed package. Is there a way for me to check what "format" the entity classes have in the old database file and compare that with the new classes definitions?   Thanks, farid #1 2015-02-13 13:10 Hello, I have an old database file with important data.
