Hi all,

I am trying to use Hibernate and Virgo. But I am facing a strange ClassNotFound Exception :

Hi,

Have you checked Virgo's documentation. We have a section that covers working with Hibernate that gives a hint to add hibernate to your application's scope so that even bundles in it without reference to hibernate can load it.
http://www.eclipse.org/virgo/documentation/virgo-documentation-3.0.0.x/docs/virgo-programmer-guide/htmlsingle/virgo-programmer-guide.html#common-libraries-hibernate

HTH,
Borislav

Thank you for answering, Borislav Kapukaranov. Razz

I already read it.

The problem seems to be one of the /reposiroty/ext (org.springframework.orm.hibernate3.LocalSessionFactoryBean) does not to import the org.hibernate.cfg package (But it currently do ! See my following post)

Caused by: org.eclipse.virgo.kernel.osgi.framework.ExtendedClassNotFoundException: org.hibernate.cfg.Configuration in KernelBundleClassLoader: [bundle=org.springframework.orm_3.0.5.RELEASE]

I can't make a par file with /ext bundles. So the import-scope:=application instruction will be useless in that case.

An other strange thing, sometimes I don't got the upper line, but the exception "stops" at :

Caused by: java.lang.NoClassDefFoundError: org/hibernate/cfg/Configuration
        at org.springframework.orm.hibernate3.LocalSessionFactoryBean.<init>(LocalSessionFactoryBean.java:189)

        at org.springframework.beans.BeanUtils.instantiateClass(BeanUtils.java:126)
        ... 20 common frames omitted

Is this exception really caused by the org.springframework.orm which try to use hibernate ?

An other guy answered me on the Spring forum :

Quote:

Maybe have a look in the virgo OSGi management interface whether
- the hibernate bundle is installed and active/started
- the hibernate bundle exports the package org.hibernate.cfg (check the version)
- the org.springframework.orm bundle imports the same version

- the hibernate bundle is installed and active/started => Yes
[com.springsource.org.hibernate: 3.3.2.GA => ACTIVE ]
- the hibernate bundle exports the package org.hibernate.cfg (check the version) => Yes
[org.hibernate.cfg 3.3.2.GA => Importing in my MANIFEST.MF org.hibernate.cfg without version specification]
- the org.springframework.orm bundle imports the same version => Yes
[org.hibernate.cfg; version="[3.2.0,4.0.0)"<unwired><optional>]

According to the class documentation at http://static.springsource.org/spring/docs/2.5.x/api/org/springframework/orm/hibernate3/LocalSessionFactoryBean.html,

org.springframework.orm.hibernate3.AbstractSessionFactoryBean Has the following method :

protected  SessionFactory 	newSessionFactory(Configuration config)

With Configuration = org.hibernate.cfg.Configuration

I suppose I did something wrong and the wrong classloader is used for some reason...

A little hint please ?

Thank you ! =)

Here is another hint.

I activated User space console to see exactly what happends:

osgi>ss

...

osgi> bundle 86
org.springframework.orm_3.0.5.RELEASE [86]
....
org.hibernate.cfg; version="[3.2.0,4.0.0)"<unwired><optional>
....

But I still have the exception in the logs :

[2011-11-18 09:19:26.723] ERROR region-dm-10                 System.err                                                        Exception in thread "region-dm-10" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory' defined in URL [bundleentry://145.fwk4098499/META-INF/spring/bundle-context.xml]: Instantiation of bean failed; nested exception is org.springframework.beans.BeanInstantiationException: Could not instantiate bean class [org.springframework.orm.hibernate3.LocalSessionFactoryBean]: Constructor threw exception; nested exception is java.lang.NoClassDefFoundError: org/hibernate/cfg/Configuration 
....
[2011-11-18 09:19:26.726] ERROR region-dm-10                 System.err                                                        Caused by: org.eclipse.virgo.kernel.osgi.framework.ExtendedClassNotFoundException: org.hibernate.cfg.Configuration in KernelBundleClassLoader: [bundle=org.springframework.orm_3.0.5.RELEASE] 
....

To conclude, the problem happends because of org.springframework.orm does not import org.hibernate.cfg.Configuration but it currently do !

So, I am absolutly lost.... Sad
