I am trying to implement tiles in my application. I have configured all files properly(as far as i am concerned, since i was learning it from tutorials on web) but when i run my application it gives me an java.lang.NullPointerException for Tiles. So can anyone please tell me whats wrong with my configuration.
I am getting the following error in console of eclipse
Hello Yogesh Thank you for your reply but that didn't solve my problem. I am using resin 4.0. But yes your suggestion will help me eradicate unwanted code in my application.
I solved the error. Actually it was occurring due to old .tld file in my tils-defs.xml and baseLayout.jsp files.
I replace the previous one
with this new one
