Re: [gemini-dev] Blueprint/JPA problem

[Costin Leau <cleau@xxxxxxxxxx>]

Blueprint cannot pickup your bundle since you have another copy of the
Blueprint classes in there (through the Require-Bundle). Instead of
importing the same packages the extender uses (or not importing them at
all unless you actually use the Blueprint API) you are making your own
copy through Require-Bundle.

To solve the problem, get rid of the Require-Bundle directive. In
general it's best not to use it...
