I don't see anything obvious in the jsp you posted that would cause this.
In fact I don't see any java code at all in there, so a null pointer exception is quite difficult to create.
you did post the source of frameset.jsp right?
Is there a 'caused by' on this stack trace?

Well the only bit of JSP markup I see in that file is the directive at the top.
Everything else is template text.
Try removing this line. Does it work?
Are there any other errors in the Tomcat log? At startup maybe?
You're working with Tomcat, so check out the file [Tomcat]/work/Catalina/localhost/JasperCIS/org/apache/jsp/frameset_jsp.java (or something similar)
This is the Servlet file Tomcat generates from your JSP. Whats on line 22 that can create a null pointer exception?
Yes,there were unnecessary jar files in the WEB-INF/LIB as well as in the build path of the project.Once all this was cleaned it worked fine.There were jars such as jsp-api.jar,servlet-api.jar and many more such jar files which were not needed. Thank you all for your help.
