Static EclipseLink weaving causing endless bundle refresh [message #1008062]

I am encountering a problem deploying a single bundle to Virgo 3.6 within my Eclipse IDE.

The bundle is a JPA persistence unit and, for my testing, has a single entity class. The bundle's Eclipse project settings specify the Virgo OSGi Bundle, Java, and JPA facets. The bundle can be deployed to Virgo fine but as soon as I enable the JPA EclipseLink static weaving at build option, the bundle will no longer deploy properly. The server view in Eclipse shows the bundle endlessly alternating between 'Republish' and 'Synchrnonized', whilst Virgo's console output shows the output below.

Can anyone explain exactly what's going on and suggest a workaround? I need to use static weaving for other reasons. Is there an alternative approach for static weaving which is more Virgo friendly?

I'm attaching the bundle's project archive.

Thanks,

Simon.

Looks to me like an issue with Gemini JPA refresh feature [1]

A possible approach to solve this is to describe JPA stuff as initial artifact in Virgo. In this way you'll have it started as early as possible so the refresh would not be needed.

Thanks for your reply. I don't think Gemini JPA refresh is the problem as I can recreate the issue with only my test bundle deployed via the Eclipse Virgo tooling. I think it's the tooling which is interfering somehow.

I have encountered problems with Gemini JPA refreshing before (see a previous thread I posted ). As a result, I have disabled its refreshing, which is why I'm trying to get the static weaving working Smile

I will try using Maven or just manually export the bundle I need to weave from Eclipse, and place in the /repository/usr directory i.e. a workaround I can live with because the bundle won't need to change much once it's working.

Hopefully someone involved in the tooling can comment on whether this is a bug or I have things configured incorrectly.

If you manage to install the bundle on standalone Virgo via the pickup directory or the repository I think we'll be able to isolate if this is a problem related to the tooling only or a general issue with Virgo and JPA.

Hi Simon

What version of the tooling are you using, are you on the 1.0.0 release or one of the 1.0.1 snapshots? There was some bundle refresh issues prior to 1.0.0 that were fixed, but they were tied to automatic manifest generation.

I loaded your sample into my dev environment to debug. I ran into issues with the JPA tooling (I can sympathize Surprised

) but once I worked past those I was able to compile the project and deploy it to Virgo 3.6 without refresh issues.

I'm using 1.0.0.201209050002-RELEASE. I tried exporting the bundle and manually deploying it to Virgo's pickup directory and it worked. I'll try updating to the latest snapshot.
