the type org.springframework.dao.support.daosuppor

I am using only the 3rd party bundles from the revision 6343, spring-osgi-core, spring-osgi-extender, io and mock are from revision 6170. (I've got compilation errors on the new version)... anyway:

The thing is that I've got a lot of class not found errors when I try to use hibernate3 and spring-hibernate3.


Bundle H is the actual hibernate bundle, which exports all the org.hibernate packages...

Bundle A has .hbm.xml, has DAO's and is using springs HibernateTemplate by extending the class HibernateDaoSupport. Actually I just need to import org.springframework.orm.hibernate3.support package to A, but I needed some more:

org.springframework.core,
org.springframework.orm.hibernate3,
org.springframework.beans.factory,
org.springframework.dao.support.DaoSupport,
org.hibernate.proxy,

This are lots of unneccessary imports for my own bundle, it seems that a lot of them are requiered indirectly by other parts of spring(-osgi)... please double check that, because a plug-in developer for my own application, which wants to use some of my DAO's in its own bundle doesn't really want to import some stuff he doesn't know about.... he just wants to import packages that he/she is using directly....

The spring-hibernate3 bundle needed also some more imports from the actual hibernate3 bundle:

org.hibernate.exception,
org.hibernate.loader.custom,
org.hibernate.engine.query.sql,
package org.hibernate.collection

spring-hibernate3 bundle seems to be incomplete... a good solution would be to import all real hibernate3 packages... please double check that, too.

The above description is just a summary of my protocal I wrote besides I resolved the errors. Here it is (from top to the bottom):

---

Invocation of init method failed; nested exception is net.sf.cglib.core.CodeGenerationException: java.lang.reflect.InvocationTargetException-->null

Solution:

Adding the package org.hibernate.proxy to my own bundle, where the DAO's are present. This shouldn't be the case,
because I just want to import packages that I directly use.

Eclipse is complaining the same thing.

DAO class:
public class myDAO extends HibernateDaoSupport implements IVorlesungsDAO { .. }

Imports from DAO bundle so far:
Import-Package: org.hibernate.proxy, org.springframework.orm.hibernate3.support;specification-version="2.1.0.SNAPSHOT-202-2"


Solution:

adding to my DAO bundle manifest the package org.springframework.dao.support.DaoSupport. This shouldn't be the case,
because I just want to import packages that I directly use.

next problem is the same, but with package org.springframework.beans.factory:

Caused by:
java.lang.Error: Unresolved compilation problems:
The hierarchy of the type VorlesungsDAO is inconsistent
The type org.springframework.beans.factory.InitializingBean cannot be resolved. It is indirectly referenced from required .class files

Solution:

adding to my DAO bundle manifest the package org.springframework.beans.factory. This shouldn't be the case,
because I just want to import packages that I directly use.

Eclipse complains:

Solution:

Adding the package org.springframework.orm.hibernate3 to my own bundle, where the DAO's are present. This shouldn't be the case,
because I just want to import packages that I directly use.

Eclipse complains:

The project was not built since its build path is incomplete. Cannot find the class file for org.springframework.core.NestedRuntimeException. Fix the build path then try building this project

Solution:

Adding the package org.springframework.core to my own bundle, where the DAO's are present. This shouldn't be the case,
because I just want to import packages that I directly use.
