A JDBC Driver or DataSource class name must be specified in the ConnectionDriverName property

Question

We're working on JSF,*EJB*,JPA project. Application server is Websphere 8.0.0.8 Everything was fine until we have started using RTC for sharing and source control. As I understand it merged configuration files and it was impossible to compile the project. This issue we've solved by repair paths to the libraries manually. But one issue we could not repair, when we try to work with JPA project and write or read something to/from DB we get the next error.

Answer 1

Ok, we found the problem. Accidentally somebody added JPA capability to EJB project and it interference with prime JPA project.
