Can any one please help me? actually what happens ?

Did you examine the WAR file that gets built to verify whether it had the struts core jar in the lib directory? — chad

Try checking your deployment dependency of your project (Properties > Deployment Assembly) and check if Maven Dependencies are included. If you try to add them using Add > Java Build path entries and then select your maven thing.

Hope that helps :)
