Org.apache.jasper.runtime.PageContextImpl.handlePageException??????

Question

I have this jsp to create Jasper report in my application which is running on apache tomcat 5. when I was running this application on my own server there was no problem. Now I am running it on main server which have the same configuration (jdk and tomcat version).but it is throwing some error which I tried to search but found no reason. :( help me.

Answer 1

java.lang.NoClassDefFoundError: sun/awt/motif/MToolkit
start here.
Im no brainiac, but it would appear that either the class does not exist or that your classpath is incorrect...
if you were able to compile you code without errors then it would appear that the problem is with your classpath.
do a "search forum" on "NoClassDefFoundError"... there are lots of explanations.
Hope it helps.
