Debugging JSP

1. Keep the generated java files

IBM websphere :
change WEB-INF\ibm-web-ext.xml as following :

<jspAttributes xmi:id="JSPAttribute_1" name="keepgenerated" value="true"/> <jspAttributes xmi:id="JSPAttribute_2" name="scratchdir" value="C:\temp\ibm"/>

Weblogic :
Change weblogic.xml as following :

2. Restart the server in debug or normal mode

3. When an exception happens in a jsp, it will show and line number. Now, you can find the java file and trace the line number and go from there.
