title: External jar configuration when debugging JSP in eclipse
body: <p>Using tomcat 7.0.11 and eclipse 3.6.1.</p>
  
  <p>I'm trying to debug a jsp file that uses log4j but I get a class not found error at runtime because tomcat isn't seeing log4j-1.2.16.jar. When I was running outside of eclipse I had to add a reference to all external jars in catalina.properties. Is there a way for me to specify this runtime reference in eclipse?</p>
  
  <p>Update:
  Here are screenshots of my current settings:

  <p>With the settings like this the tomcat catalina.properties file gets overwritten when I start up tomcat in eclipse (which wipes out the changes I made to shared.loader)</p>
