I kept all the jar files in the lib folder in eclipse even though when I am trying to run the basic application it is getting the above error?

The error is caused by GXP plugin deployed with the application, if you are not using GXPs then remove it from classpath. The referenced class is org.apache.struts2.views.gxp.inject.InjectedObjectContainer absent in the distribution. You might need additional libraries to satisfy dependency to use this plugin correctly. Certainly it is google-gxp, you can look up required libraries in the maven repository.
