It's a compilation problem, so the jars should be added to your Eclipse project. Adding jars to CLASSPATH will not help in compilation, because while compiling, Eclipse overrides the classpath with only jars that have been added to the project.

Jars are already present in the my eclipse folder in lib folder (D:\Eclipse_wrksp\Struts2Application\WebContent\WEB-INF\lib).
Do you want to me to add 'Add As External Jars' in the Eclipse porject build path??
