Pega 8.3 Sql Jdbc driver error


I've been trying to set up Pega platform 8.3 test environments for some internal testing for a client. While trying to deploy the application server I keep getting the error "

SEVERE [main] org.apache.tomcat.jdbc.pool.ConnectionPool.init Unable to create initial connections of pool.

java.sql.SQLException: Unable to load class: from;ClassLoader:ParallelWebappClassLoader

context: ROOT"

I have checked to make sure the jdbc driver is copied into the /tomcat/lib folder and also made sure its the correct driver needed. I have attached the logs. Thank you.

can you create an 'endorsed' directory under tomcat home and copy the jdbc jar there, restart pega again?

Restarting now will let you know result. Question, besides being in the /tomcat/lib directory, does the jdbc jar file need to be copied into any other directory? Thanks.

I got past the error I noted above but when I restarted tomcat, its been stuck at Server Startup. Logs have not changed and the web app has not come up. Any suggestion? Attached new log.
