I am running the application in tomcat 7.0.39. JSTLs are not working if i put extends attribute in page directive, coming null pointer exception. If i remove extends then application is working as expected. Please suggest did i miss any configurations from application or server side.
Thanks in advance.

How would we know as you haven't told us anything about what you've done?

I didn't do any configuration changes for running jstl, except putting the jstl jar file to /web-inf/lib. I want to do any configuration changes for running jstl files apart from putting jstl library?

You need to declare it on each page. (Or define a prelude that does it.)

Are you using the correct URI?

At this point, if you're not going to post code, there's not much help we can offer. Post an SSCCE that demonstrates the problem.
