Classes not found at runtime

[Anonymous]

The Problem:
I try to store an object and get a java.lang.ClassNotFoundException: Error while creating (reflection) class caused by ClassNotFoundException

Situation:
I call some basic inserts and a select all query in a testfunction. If I call this testfunction in a simple main function everything works as aspected.  If I call it in a Play! one framework controller it does not.

My guess:
It looks like this database cannot handle enhanced classes?

Solved
I solved I myself this way:

The problem beginns here:

org.neodatis.odb.impl.core.layers.layer2.instance.ODBClassPool.getClass(ODBClassPool.java:82)

It tries to get the Class from the current ClassLoader

clazz = OdbConfiguration.getClassLoader().loadClass(className);

The problem here is, that the Play! one framework uses bytexode-enhancement, it replaces changed classes at runtime and has other nice toys. It uses an own ClassLoader for that.

The line

org.neodatis.odb.OdbConfiguration.setClassLoader(play.Play.classloader);

solved my problem. I begin to like this fast database  :D
