How to use Hibernate/JPA with OSGi [message #104918] Mon, 11 February 2008 07:51 Go to next message

Hello fellows.

I am developing one application which requires persistence with database
so I am using hibernate / JPA (EJB3-JBoss).

My structure of the of the osgi bundles are as follows

plug-in 1) "my.mimos.ejb3.hibernate.plugin" has hibernate-3,
ejb3-persistence, ejb3.x and ejb3 jar files
in its MANIFEST.MF "Eclipse-BuddyPolicy: registered" is added

plun-in 2) is my jpa bundle where i want to register EntityManagerFactory
let say "my.xxx.bundles.jpabundle" in its MANIFEST.MF
"Eclipse-RegisterBuddy: my.mimos.ejb3.hibernate.plugin" is added

jpa jar ) this is my ejb project which has entity beans and
persistence.xml file in its META-INF folder. and is packed in jar file
.... let us say liberary.jar

and liberary.jar file is added into the classpath of plug-in-2 and
exported its package let us say "my.mimos.bundles.databaseservice.beans".

plug-in 3) "my.mimos.bundles.databaseservice" is my database service used
for injection and usage of entity manager of hibernate/jpa. in its
MANFEST.MF file i didn't added the buddy policy of eclipse. this plug-in
use the jpa plug and pass the peristence unit name to the jpa bundle to
create the "EntityManagerFactory"

but when i run these plug-ins i got the following error. I am posting all
console message.

Hi,

My advice it's to try to use easybeans

I'm using it, with no problems.

I've a similar problem with Eclipse RCP (v3.3.x) and Hibernate 3.2.5 and Hibernate Annotations 3.3.0.GA.
The persistence.xml is loaded and seems to work.

I try to use EntityManagerFactory for JPA, and I think this is correct.
I was able to use the Hibernate SessionFactory with Annotations before but I need full JPA compatibility so I had to switch to the EntityManagerFactory which gives me this result.

Here are some details. If more information is needed let me know.

In my console output I get this:
[..]
19:39:23,156 DEBUG JarVisitor:218 - Searching mapped entities in jar/par: bundleresource://112
19:39:23,171  WARN InputStreamZippedJarVisitor:37 - Unable to find file (ignored): bundleresource://112

[..]


But the biggest problem is this at the log:

The LinkageError (MBeanServer) is caused by the combination of Eclipse v3.3 and Hibernate.
Eclipse v3.3 includes JMX and so does hibernate via 3rd party libraries. The library in Hibernate is JBoss or to be more specific jboss-jmx.jar.

If the jmx is removed from Hibernate is should work (not yet tested, but is does make sense).

See also this posting at the Eclipse Newsgroup (from 2007) describing the exact same problem:

I have built an example that shows how to use Hibernate in OSGi. It uses Equinox, Spring DM, Maven and HSQLDB.
