Got the same error with SpringSource's hibernate bundles : (Currently working under Virgo web server (Equinox) )

Are resolved and started. I can see so

org.hibernate.cfg	3.3.2.GA	0	 x-equinox-ee:=-1
uses:=org.dom4j, org.hibernate, org.hibernate.bytecode, org.hibernate.cache, org.hibernate.connection, org.hibernate.dialect, org.hibernate.dialect.function, org.hibernate.engine, org.hibernate.engine.query.sql, org.hibernate.event, org.hibernate.exception, org.hibernate.hql, org.hibernate.jdbc, org.hibernate.jdbc.util, org.hibernate.mapping, org.hibernate.proxy, org.hibernate.tool.hbm2ddl, org.hibernate.transaction, org.hibernate.tuple.entity, org.hibernate.type, org.w3c.dom, org.xml.sax
x-internal:=false

in com.springsource.org.hibernate: 3.3.2.GA. So the package exists.

In my bundle-context I got:

<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
			<property name="dataSource" ref="dataSource"/>
			<property name="mappingResources">
				<list>
					<value>/hibernate/MyProfile_document.xml</value>

				</list>
			</property>
			<property name="hibernateProperties">
				<props>
				<prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
				</props>
			</property> 
	   </bean>

And in my MANIFEST.MF, I got

With the dataSource as a service (following Spring-DM good practices):

<osgi:reference id="dataSource" interface="javax.sql.DataSource"></osgi:reference>

And in the datasource bundle :

        <bean
		class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
		<property name="locations">
			<value>classpath:META-INF/spring/database.properties</value>
		</property>
	</bean>

	<!-- Database Properties -->
	
	<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
		<property name="driverClass" value="${driver.classname}"></property>
		<property name="jdbcUrl" value="${database.url}"></property>
		<property name="user" value="${database.username}"></property>
		<property name="password" value="${database.password}"></property>
	</bean>
       <!-- Data Source service -->
       <osgi:service id="dataSourceService" ref="dataSource" interface="javax.sql.DataSource"/>

I Also added <Import-Bundle>com.springsource.com.mysql.jdbc</Import-Bundle> to the com.springsource.com.mchange.v2.c3p0 library. (Using c3p0 instead of the SessionManager and it's annoying class.forName() )

I don't understand what I have done wrong....

When I run my bundle, got the following error:

Why is org/hibernate/cfg/Configuration not found ???

Any help will be greatly apreciated !

Thank you !

Have you tried to import the package org.hibernate.cfg in your bundle (or the bundle that throws the exception)?

When you are not using an autogenerated MANIFEST.MF I would recommend this, it is very convenient and will save
you a lot of problems. Have a look at bnd / bndtools / maven-bundle-plugin / bundlor for this.

Got a more precise error message:

May it be because teh bundle containing org.springframework.orm.hibernate3.LocalSessionFac toryBean in /repo/ext of Virgo ( = org.springframework.orm-3.0.5.RELEASE ) is not importing org.hibernate.cfg ?

If it's the case, I am a bit lost =/ I don't know how to solve the problem... (Modifing a MANIFEST of a bundle in /repository/ext is too ugly)

[toelen]

Hey,

the bundle that cannot load the package org.hibernate.cfg is org.springframework.orm_3.0.5.RELEASE. This might be because of a problem in that bundle (which I doubt) or because the package org.hibernate.cfg is never exported (or not with the correct version at least).

http://www.eclipse.org/virgo/documen...html/ch07.html

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

and check the log files for classloading exceptions.

Leen

Thank you for answering, I posted the same thread on Virgo forum,

Here are the answers:

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/documen...ries-hibernate

HTH,
Borislav

Thank you for answering, Borislav Kapukaranov.

I already read it.

The problem seems to be one of the /reposiroty/ext (org.springframework.orm.hibernate3.LocalSessionFa ctoryBean) does not to import the org.hibernate.cfg package (But it currently do ! => see http://www.eclipse.org/forums/index....78/#msg_757378)

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)

        ... 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 title=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
[/quote]

- 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/sprin...toryBean.html,

org.springframework.orm.hibernate3.AbstractSession FactoryBean 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 ! =)
