Question

I'm getting the following error when I run the application :
I'm using OAS 10.1.3.0 and upgraded to 10.1.3.3 on Linux
it strenge that according to the error message the server knows the missing class is available from the certain locations. but why it's still give error.
by the way, if I copy the jar to the j2ee/home/applib folder, the problem resolved. I'm wondoring if there some configurations need to be done.
error message:

Answer 1

We have found a workaround for this situation. We just removed the connection factory class in our app that was using com.evermind.sql Data source (com.evermind.sql.FilterConnection), instead we are using the default installation factory class: oracle.jdbc.pool.OracleDataSource.
Why Oracle has removed several classes (such as com.evermind.sql.FilterConnection) from oc4jclient.jar since OAS 10.1.3. This will create compilation and runtime error if the somebody would like to use the legacy connection factory classes that were supported in previous version of OAS, but are removed without documentation in the new OAS 10.1.3?
Write once, debug anywhere ......It's painful
