BC4J, OC4J and MySQL

Question

I have been trying to get this configuration working. After much progress, I am getting for following error even though I am pretty sure that I have the datasource defined correctly:

Hi, first of all thanks for your interest and sorry for my English.
Actually I have tried some different combinations.
First of all I downloaded 9ias v1.0.2.2 core form web-site. In it oc4j comes with version 1.0.2.2.1. I installed it and could not even get that error message. Then I installed bc4j runtime installer over it. Then I got that error message.(That message is just an example. I think not all of the necessary classes with correct versions are contained in the container.). Then I tried to use the oc4j that is embeded in the jdeveloper release candidate. I copied the directory and put to the proper place in the application server. It did not even start. Finally I downloaded 9ias Release2-j2eedeveloper's preview. It brougth me a version 9.0.2.0A. I was wery hopeful with it but it did not work either.
I only want to deploy and use my jsp files that I created by jdeveloper release candidate. I need correct versions of application server and container I think.
Thanks a lot.
