Re: [eclipselink-dev] osgi persistence.xml hack

["Tim Hollosy" <hollosyt@xxxxxxxxx>]

Unless you have an osgi project that hits a db right now that you can
create a product for and export from the pde then i'm not sure you'll
be able to recreate it. I would do it myself with the comics crud
example I submmited, but I switched dev boxes recently and don't have
the comics derby db handy right now, otherwise i'd just do it. I think
i'll be able to do it tommorow though.

The bug is here: https://bugs.eclipse.org/bugs/show_bug.cgi?id=226361

You could try checking out that project get it running in eclipse,
then creating a product for it, exporting it as an exe and see if it
works.

Let me know if that makes sense.
