"java.lang.ClassNotFoundException: oracle.jdbc.pooling.Factory"

Question

I'm having some sort of problem with ucp.jar

If I use ucp.jar for oracle 12.1.0.1 it works.

If I use the version for oracle 12.1.0.2 then I get the following exception:

java.lang.ClassNotFoundException: oracle.jdbc.pooling.Factory

Is there anyone who can help me?

Thanks, Mauro

Answer 1

The Jdbc (ojdbc7.jar) and UCP (ucp.jar) jars must always be from the same version (12.1.0.2). You can't upgrade one without upgrading the other. This version dependency was introduced in 12c. It wasn't the case before.
