I am using Netbeans 6.7 with Tomcat 6.0 and jasper reports for generating reports in a web application. I always get this exception when I run my application. can someone please help me out?

The exception is

INFO: Illegal access: this web application instance has been stopped already.  Could not load org.apache.log4j.spi.NOPLoggerRepository.  The eventual following stack trace is caused by an error thrown for debugging purposes as well as to attempt to terminate the thread which caused the illegal access, and has no functional impact.

It could be due to a memory problem, I had this message and also a java.lang.OutOfMemoryError: Java heap space, adjusting startup parameters to: -XX:PermSize=512M -Xms1024m -Xmx4096m solved the problem the problem.
