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.
Should this be added with my web application under the WEB-INF/lib folder? Or should it be placed in the weblogic lib folder?
Unless you have gone tear-assing around your WLS installation you are not missing servlet.jar
...
From WLS version 10 onwards, you will find it as $BEA_HOME/modules/javax.servlet.x.y.z.jar
