title: Tomcat: OutOfMemoryError Permgen Space
body: <p>I am developing a JSP application using Tomcat 6.</p>
  
  <p>Since I did add Quartz Scheduler Framework and Log4J library to project, Tomcat start throwing this exception when redeploying.</p>
  
  <p>I have readed about the problem causes, and now I know that have to be with the class loader.</p>
  
  <p>So, I guess the problem can be caused by the logger library that load some classes automatically.</p>
  
  <p>How can I deal with this problem?
  There is alternative way to setup the logger without using the log4j.properties file to ensure that classloader will work correctly.</p>
