Re: [eclipselink-users] Does OSGI work?
The DB should be generated by running the org.eclipse.persistence.example.jpa.comics.setup (ComicsExampleDBSetup).
I agree, we should integrate DB generation into each demo so these issues do not occur. We just have not had a chance to do that yet. 

We also plan to update the wiki.

Here's a copy of my derby db with the comics DB already generated:

You just need to set up the derby DB first, the database does not
exist yet. I believe it says how to do it on the wiki page, but it's
so odd I just use a copy of derby I have with the DB generated
already, I don't remember how I did it initially.

Hi Hugo,

 Lets see if we can get the examples working for you.

 Your 1st step should work.  After that, there are a few things we should do
differently.

2. The osgi branch in our SVN is a proof of concept branch and is therefore
deprecated.  We will update our Wiki to be more accurate.  Instead, get the
examples from the "examples" folder in either our trunk, or
branches/1.0/trunk.  The example projects you want are:

org.eclipse.persistence.derby
org.eclipse.persistence.example.jpa.comics.model.annotated
org.eclipse.persistence.example.jpa.comics.setup
org.eclipse.persistence.example.jpa.rcp.comics

3. You are correct to install apache derby, but the org.apache.derby.core
bundle is not JPA friendly (it is not well setup for a client-connection to
Derby through OSGi).  The org.eclipse.persistence.derby project you imported
in the step above can be used to provide Derby access.  See the readme file
in that project to understand how to configure it.

When you have it configured, you will have to run the startNetworkServer
script in your derby installation

4. You should only have one compile error.  It is explained in the readme
mentioned above and you should not have to worry about it.

5. Run the ComicsExampleDBSetup launch configuration (from the
org.eclipse.persistence.example.jpa.comics.setup project)

This is a simple OSGi application that sets up your database.

6. Run the ComicsRCP launch configuration (from the
org.eclipse.persistence.example.jpa.rcp.comics project)  You will get a
warning about the derby jar.  Click on the button to ignore the warning.

You should get a simple RCP app.

Let me know how this goes for you and we will ensure the wiki gets updated.

Running the 1.0 branch

Step 2 should include the url to svn in tr (you mentioned it in
another email in this list) and not the old technology svn.
The wikipage http://wiki.eclipse.org/SVN_Howto has to be updated.
I know the Equinox group is migrating the source to tr...

Could the DERBY_HOME be obviated by implementing Eclipse-RegisterBuddy
but then... I guess this would not be OSGi??? Is there and equivalent
to Eclipse-RegisterBuddy in OSGi??

The run configuration for the RCP has to be reset with the required
plugins since I am testing on Linux.

I got this error both in Windows and Linux:
