Hello,

I'd like to use Hibernate 2.1 with JBoss via JCA.
I wonder how can I configure JBoss to do it. I don't want to use the way via JMX.

So I put the file hibernate2.rar in the /deploy folder.
What should I do after ?

I post a question on the JBoss Forum and Adrian told me to write a configuration file hibernate-ds.xml like this :



I tried to put the parameters as the ones used for integrating Hibernate with JBoss via JMX but I send me an error.

Does anybody try to do this ?

Regards

See: http://www.hibernate.org/66.html.

I would not recomend doing this though! You are limiting you ability to test, hurting portablility... I would look at how springframework does this for you!

Thank you for your quick answer mlavwilson.

In read carefully the document you had mentionned.
I was a bit disappointed when I read it. In fact, I understood that I've to build a SAR file "which will include all the entity objects, mapping XML files, and the JBoss service XML file itself". This solution doesn't please a lot. By this way I put a part of my own application into the SAR file.

I wanted Hibernate to be as an other system that my own application use it to manage persistent objects. Is that possible ?

I wonder if the solution can managed multiple accesses and cache sharing.

This is currently not practically possible. You currently need one hibernate sar per application. We are working on making this more convenient with the new Hibernate Deployer structure.

Does this solution eliminate the dublicate deployment of my data files and their mappings? What is the status? Something coming up soon, or for the moment not a solution?

Well, duplicate deployment can already be avoided in its current state by a proper packagin structure. But I agree that this has to be documented more clearly, and I hope I find time soon to work over the JBoss integration docs.

I try to use Hibernate deployed as a SAR in a JBoss application (EAR).

So all the libraries needed have been put into the $JBoss_home/server/all/lib. I build the Sar and the Jar. The 2 archives are correct because I can use them well when they are not deployed in the same EAR.

When I try to pack them in a EAR, it doesn't work well. I got the following ERROR :

17:06:26,250 ERROR [STDERR] javax.naming.NameNotFoundException: hibernate not bound

In fact my hibernate SAR is not deployed. I don't understand why.

Here is the composition of my EAR :

Hibernate.ear :
/Hibernate.jar
/hibernate.sar
/META-INF/application.xml
/META-INF/jboss-app.xml
/META-INF/Manifest.mf

Here is my file application.xml :





Here's my jboss-app.xml :





Does someone look at something wrong ?

I succeed to make it work.
I don't know exactly how in fact. I named META-INF in minuscules. When I renamed it with Capital Letters it's worked fine.

And the hot deploy works fine for you or you have to restart jboss when you have a new deploy?

The Hot deploy works fine I do not need to restart JBoss.

My hot deploy don't works.

I've tried to add the line:
<loader-repository>hibernate:loader=Hibernate.ear</loader-repository>

in my jboss-app.xml

but now don't work the deploy and I've received this exception:
