do you have any of the jar's listed at below URL?
http://www.findjar.com/class/org/springframework/web/servlet/DispatcherServlet.html

You did mention mvc, but wanted to be sure.

[nisu pathak]

what is the folder structure pointing to the jar file in your lib in your war / ear / jar? is it under WEB-INF/lib?

http://tomcat.apache.org/tomcat-5.5-doc/class-loader-howto.html

[[EDIT]] Adding link from tomcat documentation

[nisu pathak]

i have included all jars associated with spring core and spring mvc into as a userlibrary.
is it ok or should i add all jars to WEB-INF/lib folder?

[Krishna Kanth]

Can you elaborate a bit more on "UserLibrary"? and its path inside war?

all jars should be under WEB-INF/lib folder or common/lib of tomcat (if you are on tomcat-5.5) according to the tomcat documentation on above URL.

Actually i have added all jars by building class path .eclipse provides this option in order to add librarby thats what is called UserLibrary.is it compulsary to add all jars into lib folder ?thats what i am asking?
