1. Re: java.lang.ClassNotFoundException: org.hibernate.MappingException not found
marcomac Oct 20, 2011 5:28 AM (in response to nannou9_piotr)Hi
I faced the same issue on FUSE ESB 4.4.1-fuse-00-08.
It's a blocking issue for us at the moment is there any work around?
Here my situation:
JBoss Hibernate Common Annotations (3.3.0.ga)
JBoss Hibernate Annotations (3.4.0.GA)
Hosts: 253
JBoss Hibernate Entity Manager (3.4.0.GA)
Hosts: 253
JBoss Hibernate Object-Relational Mapper (3.3.2.GA)
Fragments: 251,252
karaf@root> exports | grep "org.hibernate;"
251 org.hibernate; version=3.4.0.GA
253 org.hibernate; version=3.3.2.GA
253 org.hibernate; version=3.4.0.GA
it would be appreciate any help on this point.
Best regards
Marco

nannou9_piotr Oct 20, 2011 3:50 PM (in response to marcomac)Simple download apache servicemix trunk, then build your own ESB using mvn -Pfastbuild. After about 20m you will get working ServiceMix. This is my solution which is working perfect for me.
I know that best would be to find the bug and solve the problem, but I do not have time for now.
Hope that this problem will be solved soon. If not, then maybe one day i will find more time than just few minutes for Apache and Fusesource

nannou9_piotr Oct 31, 2011 10:12 AM (in response to nannou9_piotr)I have to sadly confirm that new version of fuse esb 4.4.1-fuse-01-06 have very same problem (bug?).

davsclaus Nov 1, 2011 4:36 AM (in response to nannou9_piotr)Its not Fuse ESB problem per see.
Its Hibernate not being OSGi compliant.
OpenJPA is OSGi compliant, JPA1/2 spec compliant, and much ligher and faster than Hibernate.

nannou9_piotr Nov 2, 2011 4:58 PM (in response to davsclaus)You are right Claus... but the thing is, that the problem occurs using jpa-hibernate feature which is fuse specific.
So, maybe it would be a good idea to use maven-shade-plugin to repack all hibernate bundles into one "super" bundle?
So repack:
org.hibernate/com.springsource.org.hibernate.annotations.common/3.3.0.ga
org.hibernate/com.springsource.org.hibernate.annotations/3.4.0.GA
org.hibernate/com.springsource.org.hibernate.ejb/3.4.0.GA
org.hibernate/com.springsource.org.hibernate/3.3.2.GA
into for example
com.fusesource/org.hibernate/3.3.2.GA
Another idea is to switch to hibernate 4, which seems to be better organized (in osgi meaning).
Let's say that you will pick the solution that would be best (in your opinion) and i will do my best to bring it to reality?
The thing is that I need a working solution in about 1 month as i am about to start production use of a solution based on hibernate jpa soon.
What do You think?

davsclaus Nov 3, 2011 3:57 AM (in response to nannou9_piotr)If you have a FuseSource subscription then I suggest to use that channel to get help with the hibernate and to help meet your deadline.
Hibernate is LGPL licensed so its much harder to officially support it from 3rd parties.
Yes Hibernate 4.0 may be better OSGi compliant. At least JBoss AS 7 is heading in the OSGi direction, so I guess JBoss would want to make using Hibernate possible.

7. Re: java.lang.ClassNotFoundException: org.hibernate.MappingException not found
nannou9_piotr Nov 3, 2011 8:06 AM (in response to davsclaus)Unfortunately my company do not have FuseSource subscription yet. We are about to buy it at the beginning of 2012 (which is too late according to my deadline but the final decision was not mine).
So are there any plans to use hibernate 4.0 by jpa-hibernate feature?
As i said i can help you doing this improvement, but you have to tell me how to contribute the code to Fusesource? As you probably know i am an Apache contributor already, but Apache foundation does not support jpa-hibernate feature. So where can i create an improvement task and upload the code?

davsclaus Nov 3, 2011 9:49 AM (in response to nannou9_piotr)You can send me a private mail. And I can help get in touch with someone, so we can look into what we can do to help you with that hibernate issue.
Just mind that getting Hibernate 3.x to work in OSGi is hard. And if you use class based proxy using ASM or the likes, its even harder. And as well those TX annotations.
BTW Are you using Blueprint or Spring DM? The latter also have some issues in terms of classloading etc. Blueprint is much better.
My mail is claus dot ibsen AT fusesource DOT com.

marcomac Nov 4, 2011 10:24 AM (in response to davsclaus)Hi
I've posted before that I had the same problem and actually it seems a problem of Hibernate.
What we figure out is uninstall the two bundles
251 Resolved 60 JBoss Hibernate Annotations (3.4.0.GA)
Hosts: 253
252 Resolved 60 JBoss Hibernate Entity Manager (3.4.0.GA)
and redo a
features:install jpa-hibernate
this seems fixing the issues in a way that we can access the db and the ClassNotFoundException seems going away.
I know that is not a clear solution but at least works.
In the meanwhile I'm looking at Open JPA but I didn't find yet an example with spring.
I've seen that C. Moullard has posted an example with camel-aries but not yet seen it properly.
Is there a plan to fix this Hibernate issue on next releases? I've the time constraint indicated above by some other people.
Regards
Marco

11. Re: java.lang.ClassNotFoundException: org.hibernate.MappingException not found
marcomac Nov 4, 2011 11:15 AM (in response to davsclaus)Hi
I'm not using Spring DM, just service mix 4.4.1-fuse-01-06 with Camel 2.8.0-fuse-01-06.
Basically we have two modules
- one the WS interface with CXF 2.4.2-fuse-01-06 that calls the DAO.
- one that make the DAO with Hibernate, originally it was an OSGI module deployed by itself in the 4.3.1 (not fuse) but in the 4.4.1-fuse-01-06 we needed to import in the WS module because I couldn't deploy it anymore. We got this exception (subject of this post) and I solved with that trick.
We moved from 4.3.1 to 4.4.1-fuse-xx-yy because of the services on the same port. that are available under .../cxf/ only from the 4.4.1. Where there was even the issues related to Servlet 3.0 e 2.5 with Jetty ;-). That I solved.:-)
so at the moment I'm planning to change to OpenJPA and next week somebody of Progress will pass by but in the mean while we sorted out a lot of issues.
Let me know if you need more info

nannou9_piotr Nov 18, 2011 6:52 AM (in response to davsclaus)I have sent a pm message to Claus with a solution: pom.xml that repacks hibernate bundles using maven-shade-plugin.
