Trouble with an axis2 web service and persistence
I installed Jetspeed2, works fine.
I plopped Axis2 into Jetspeed2 as per the instructions.
I installed a trivial web service, works fine.
Now I am trying to add persistence to my web service. Is there anything in Jetspeed that would cause a web service to not be able to persist objects? The idea sounds insane to me but I have to ask.
I asked more specific "why does this not work" questions on the Axis2 list, of course.

I had the same issue. One of the things I found is that Hibernate needs
the proper versions of slf4j and log4j but it doesn't specifically
complain about not having them. You get an error message about ejb3
instead. You can test your assumption about not finding the config file
by hard coding the config file, i.e. by creating a Configuration in your
code and hand it the config file. That shouldn't be necessary though.

Re: Trouble with an axis2 web service and persistence
Posted by ANTHONY ENNIS <to...@insightbb.com>.
There are a few problems I think. What isn't helping is the layers here.
1. If you want a webservice, you have to package your classes etc in a certain way.
2. If you want persistence, you have to package your classes in a different way.
3. If you want a webservice with persistence, no one knows how to package it, as far as I can tell.
My problems have nothing to do with Jetspeed so long as Jetspeed doesn't do *something* to make persistence different. But that would be totally nuts but I thought I should check, to see if anyone had a memory of "Oh yeah, in that case you have to jump up and down 4 times when you deploy..."
My specific problem is an exception when I'm calling EntityManager: javax.persistence.PersistenceException: No Persistence provider for EntityManager named xyzzy.
Of course, there is. However, it looks like my code can't find the file, or I have something wrong in the file and I'm getting a really really sorry error message. But again, that isn't Jetspeed.
I'm checking assumptions is all.

As Ate says, your question is kind of broad. What is it exactly that
you're trying to do?
I use Hibernate in my portlets, I don't see why Hibernate or any
persistance api would cause problems, other than some dependencies that
you have to resolve.

Short answer:
No.
Long answer:
Your question really is too simplistic with no indication how/where/what you try to persist that a sensible answer cannot be given.
If you encounter a problem which *might* be related to the way you packaged and deployed your web service into Jetspeed and you want to find
out if it possibly might be caused by conflicting interactions with Jetspeed and/or the packages/jars on the classpath, you'll need to
provide us more details.
Possible library (version) conflicts of course *might* cause problems, so if you have an idea it is something in that area you should
carefully compare the Jetspeed provided dependencies and those needed by your web service. And then, *if* you found a conflict, there are
probably plenty solutions possible to resolve them (different or separate packaging/deployment, upgrading dependencies, etc.)

Good thing. I'd suggest first investigating there and if that comes back pointing at your deployment environment, we might be able to help
you out further.
