Summary: 0000015: com.caucho.amber.AmberRuntimeException: 'example.model.MyDataPO' is an illegal instance class ?
Description: RSN-5
I get the following error trying to start my server (using a resing project with resin eclipse configured). But my entity bean example.model.MyDataPO seems to be correct looking like what you specify in the resin doc for EJB3.
I give you in attachement all my project. If this exception is normal then it should be better documented. Could you please help me to solve this dilemn ?

It seems that it is because the entity bean has not been enhanced, but I don't known how to force enhance entities. Does I need a specific class loader or does I need a specific resin.conf configuration file ? In this case could you add the resin.conf file in your online tutorial examples to enable user to try your examples ?

Sorry this is not a bug from resin : I try may application directly using the resin server (not with the resin eclpise plugin) and ejb3 tutorials work good and my example is on the way to work.
This is more a configuration problem with the resin eclipse plugin that provide a different resin.conf file.
All the way you can close this issue.

Please don't close this bug, because it does happen outside the Eclipse plugin.

My environment is Resin-3.0.12/Sun JDK 1.5.0 or Sun JDK 1.5.0_02/Linux/postgresql 7.1

The following case generates this bug:

A web-app with two ejb-server, a session bean A in the first ejb-server references a entity bean X of the second ejb-server. The entity bean X is loaded by the first ejb-server and isn't enhanced.

The error message has been fixed. The underlying problem is some issue compiling the generated files, but that compilation error was not being propagated to the calling context.

With that error message fix, you'll still get an error, but it will be a bit more informative. (In other words, the underlying bug still exists, but it may be easier to track it down.)
