Hi,

That code was fixed quite a while back, if I recall correctly. What version are you running?

Regards

i'm running Alfresco 2.0.

I just got a difference here…

Alfresco's hibernate (3.2.1 right?) jar file is different (less packages and less classes) than the hibernate 3.2.1 I got from hibernate.org.

Is it a patched version?

Hi,

The name of our Hibernate jar is incorrect. Actually, Alfresco is using the 3.1.3. You can check in the manifest file in the jar. We have a branch with the Hibernate upgrade on. One of the effects of the upgrade to Hibernate is the error you are seeing. We've fixed that on the code branch.

The Hibernate upgrade, which turned out to be a lot more complicated than just updating the jar, will be coming to HEAD soon. Ofcourse, we like to keep the project stable as a priority.

If you just change the code at that exception, you'll still not be able to run the app with 3.2.x of Hibernate. There're a whole package of fixes that will come with it.

Regards

Ahn, got it. When I saw it was using hibernate 3.2.1 (through the jar's name) I left my own hibernate jar in the project.

So far I had problems only with this job runing Alfresco Embedded in my project.

Is this job (org.alfresco.repo.node.index.IndexRecoveryJob) mandatory for alfresco to run correctly? I'm using only the most basic features like adding and searching content, no workflow or versions.
I can't rollback hibernate's version in my project right now.

If it is not mandatory, how I disable it?

You're on your own if you use another jar. It is not the only issue. But set the index recovery mode to NONE.

I know that it's my responsability.

I'll use this this way until a new version comes out.

Thanks!

That's an important change indeed. Are you releasing it other than in SVN?

Yes those updates will be available in the next formal release 2.1.

Thanks,
