Hi,

Does anyone know why a hibernate class can't be found while attempting to compile its respective mapping document (xml.hbm) during deployment?

I think the problem is due to classloading, but I don't know how to solve it. Everything else seems to deploy fine. I'd really appreciate any ideas...

Regards,
Itchy


More facts:
The class is located in a .jar, whereas the mapping document is within a .sar. Directory structures are identical.


The error message states:
ERROR [Configuration] Could not compile the mapping document net.sf.hibernate.MappingException: persistent class [com.kemaiev.jzudi.hibernate
.CompanyHibernateImpl] not found
at net.sf.hibernate.cfg.Binder.bindClass(Binder.java:84)
.........etc......



Also, within jboss-service.xml:
attribute name="MapResources"
com/kemaiev/jzudi/hibernate/CompanyHibernateImpl.hbm.xml
attribute

Do you have deploy your mapping classes and jboss-service.xmlm in a sar archive?
You are using Jboss I think:) look into the tutorial.
Could you post your jboss-service.xml.?

subich,

Thanks for replying to my post so quickly. To answer your question: yes, I am using JBoss...I should have mentioned that--sorry. I am using the tutorial at: http://www.hibernate.org/66.html Plus I've read WIKI and the Getting Started docs. Nothing helped yet, but I think I'm very close to a successful deploy. Here is how my directory structure looks:


1).jboss-service.xml is in the META-INF directory of Hibernate.sar.
2).com/kemaiev/jzudi/hibernate/CompanyHibernateImpl.hbm.xml is in jZUDIHibernate.sar
3).com/kemaiev/jzudi/hibernate/CompanyHibernateImpl.class is in jZUDIHibernate.jar
4).Hibernate.sar is in jZUDI-MiddleTier.ear
5).jboss-app.xml is in META-INF of jZUDI-Middle-Tier.ear


HERE IS THE jboss-service.xml:



HERE IS application.xml:




HERE IS jboss-app.xml:




HERE IS THE (almost) COMPLETE PRINTOUT:
I think the part in red is due to the hbm.xml not compiling in previous step (also listed in original post).

Oooops

'4).' should be jZUDIHibernate.sar is in jZUDI-MiddleTier.ear

and not

Hibernate.sar is in jZUDI-MiddleTier.ear

Ok now it works?? :)

subich,

Thanks for staying with me on this. No, unfortunately it still doesn't work. The 'Ooops' post was just to correct an error in the previous post. I didn't mean that I found the programming error.:(

In fact, I'm still getting the same error:




The JZUDIHibernate.sar MANIFEST.MF looks like this:


Again, here is a better description of my directory structure:

Ok nice, I think I see the problem.
Normally, you should your class files in the sar archive when you use JBoss mBean services.
Try with an archive lihe this

Application.sar
+----->META-INF/application.xml
+----->META-INF/jboss-service.xml
+----->com/application/XXX.class
+----->mapping/com/application/XXX.hbm.xml

Wow! Using structure mapping/com/kemaiev/jzudi/hibernate
/CompanyHibernateImpl.hbm.xml makes a big difference. Now it seems to compile. Interestingly, it also compiles when the .class file is within jZUDIHibernate.jar, instead of placing it in jZUDIHibernate.sar. The result seems identical, as long as the mapping directory is added. Also, no MANIFEST.MF Class-Path is needed for this step. I'll keep experimenting with these things.

A small problem though. The new path isn't being picked-up in jboss-service.xml. It is still recording:

(from jboss-service.xml)


It should including 'mapping/' in front of com/... but the Ant-task doesn't pick-up change. It is causing a problem with creating the SessionFactory (See output below). In any case, THANKS SO MUCH FOR YOU HELP SO FAR! I don't think I would've figured the directory structure issue out on my own.

Itchy


The structure now looks like this:
jZUDI-MiddleTier.ear
+- META-INF/application.xm
+- META-INF/jboss-app.xml
+- jZUDIHibernate.jar (archive)
| +- com/kemaiev/jzudi/hibernate/CompanyHibernateImpl.class
+- jZUDIHibernate.sar (archive)
| +- mapping/com/kemaiev/jzudi/hibernate/CompanyHibernateImpl.hbm.xml
| +- META-INF/MANIFEST.MF
| +- META-INF/jboss-service.xml



Here is output:

I don't put my classes on a jar into a sar. I put all of them into the sar without a jar archive.
I think, I add nothin more in the manifest.
Sorry but I haven't got my laptop with me today.
I can look this tonight and give you a response soon.

Good luck.

Kind regards.

another thing your last error is due to the jboss-service.xml change the path for the xml files.
When I depploy I use a directory mapping and I change the path in the jboss-service.xml.
Update your mapresources with your own path

<attribute name="MapResources">mappings/MasterAccount.hbm.xml,
mappings/SubAccount.hbm.xml,
mappings/Password.hbm.xml</attribute>

Thanks subich, that sounds like a good idea, but I'm travelling until Tuesday, so I can't try it until then. Have a good weekend!

Ok you're welcome.
Tell me if it's all right.

Well, I'm finally back now. Changing the path in mBean does indeed help. It now finds the mapping file; however it doesn't find the class, even though I included it in the .sar. I experimented by adding a 'classes' directory in front of the package directory tree (see structure below). Then I changed the path in the mapping document to include the new 'classes' directory.

I've done everything I could think of--all possible combinations of directory structures/mappings, with and witout 'classes' directory, but it just doesn't seem to find the class. It is the same error from my original post, but perhaps for a different reason. I'd appreciate any suggestions :)

The output from deployment:





The structure now looks like this:
jZUDI-MiddleTier.ear
+- META-INF/application.xm
+- META-INF/jboss-app.xml
+- jZUDIHibernate.sar (archive)
| +- mapping/com/kemaiev/jzudi/hibernate/CompanyHibernateImpl.hbm.xml
| +- classes/com/kemaiev/jzudi/hibernate/CompanyHibernateImpl.class
| +- META-INF/MANIFEST.MF
| +- META-INF/jboss-service.xml


The path in mapping with 'classes' directory:


The path in mapping without 'classes' directory:

On wich file you put these line?

<hibernate-mapping>
- <class name="com.kemaiev.jzudi.hibernate.CompanyHibernateImpl

It is included within:

+- jZUDIHibernate.sar
| +- mapping/com/kemaiev/jzudi/hibernate/CompanyHibernateImpl.hbm.xml

and CompanyHibernateImpl.hbm.xml is generated automatically by the <hibernatedoclet task.


I'm working on it now...maybe I just overlooked something obvious? I'll post if I find the mistake.
