title: How and where to add Servlet.jar to Weblogic 10?
body: <p>I have a web app that is failing I believe due to the lack the servlet.jar library. It works fine in tomcat, but fail with 500 error and no stack trace under Weblogic 10.</p>
  
  <p>Should this be added with my web application under the WEB-INF/lib folder? Or should it be placed in the weblogic lib folder?</p>
