Factory

Dear All,

As part of getting Hibernate to work on the bus, I started getting these errors in my bundle even though I explicitly embed all cglib classes in that bundle (just in case, although this is not desirable in a production system, of course). This happens with almost any bean in my context file, as spring attempts to proxy them and fails. What am I doing wrong?

1. Re: java.lang.NoClassDefFoundError: net/sf/cglib/proxy/Factory

oren Sep 2, 2009 12:46 PM (in response to oren)
I tried to create my own osgi bundle around cglib and cglib_nodep and use it in my bundle (including importing net.sf.cglib,net.sf.cglib.*), but that didn't help. I suppose that the cglib Factory class is not found by the OSGi spring context extender bundle. However, I am sure that many people are using cglib in their bundle, and it is also a system bundle (#41 in my installation). So why isn't it found in my bundle?

Here's the latest error message:

oren Sep 2, 2009 12:53 PM (in response to oren)

The first bean seems to be fine (abstractFactory). I think it uses cglib as well there too. Why does only the second bean fail? Do I need to change anything in the module that declares that abstract bean whose method is injected here (edu.utah.further.mdr.api.util.XQueryDataSource)? I tried to add net.sf.cglib* there, but it still fails.

Solved the Hibernate issues using a truly complicated pattern that includes embedding the Hibernate classes into the bundle using the Felix BND maven plugin.
