Answer 1

Illegal access: This web application instance has been stopped. Unable to load com.mchange.v2.c3p0.impl.poolbackeddatasourcebasebeaninfo. The final stack trace is the error raised for debugging purposes and the attempt to terminate the thread that caused the illegal access, and has no functional impact.

The package com.mchange.v2.c3p0.impl.PoolBackedDataSourceBaseBeanInfo was not found in your project. Please check again to see if it is a problem with your project. If so, try repairing it and re-releasing it. If it doesn’t work, try reinstalling tomcat and jdk.
