Your CommonCode solution is the way I went (I called mine BaseActionHelper).
Your subclass of DispatchAction would look something like this below.
public abstract class MyDispatchAction extends DispatchAction
{
public ActionForward execute(ActionMapping mapping,
ActionForm form,HttpServletRequest request,
HttpServletResponse response)
throws Exception
{
//common code for all action classes
CommonClass cc = new CommonClass();
// just sample method
cc.doValid();
return super.execute(mapping, form, request,
response);
}
}
