The execute method can be used to put code that will apply to all the
dispatched methods.

public class BasicInfoAction extends DispatchAction {
private String thing1;
private String thing2;
public ActionForward execute(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response) throws Exception {
thing1="The cat in a hat"
thing2="The cat in a hat"
request.getSession().setAttribute("thing1", thing1);
request.getSession().setAttribute("thing2", thing2);
return super.execute(mapping, form, request, response);
}
public ActionForward display(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response) {
System.out.println("method=display");
return mapping.getInputForward();
}

I understand your description of DispatchAction and my use is good.

I'm sure we passing the good "method" parameter but sometimes the
error appears in the stack trace!.

I don't have the possibilities to reproduce the error. The error
appears in production (error occurs from time to time). ;)
