Check if your action file (type=xxx) exists in your struts-config file. If "action" is also defined, check if a method with the same name is present in your action. In case parameter is defined, but not present in parameters, you have to create a "unspecified" method in your action. If you don't use "parameter" in your struts-config file, use an "execute" method .

///////////////////

exemple with parameter defined in the strust config:

url: yoursite.com/mypage/myaction.html?method=test

<action
  path="/mypage/myaction"
  type="myfolder.action.MyAction"
  name="MyActionForm"
  validate="false"
  parameter="method"
  scope="request">
  <forward name="success" path="/view/yourfile.jsp"/>
</action>



public class MyAction{


 public ActionForward test (ActionMapping mapping,
         ActionForm actform,
         HttpServletRequest request,
         HttpServletResponse response) throws Exception { 

                 ...

  return mapping.findForward("success");

 }


}

exemple without parameter defined in the trusts config:

url: yoursite.com/mypage/myaction.html

<action 
  path="/mypage/myaction"
  type="myfolder.action.MyAction"
  name="MyActionForm"
  validate="false"
  scope="request">
  <forward name="success" path="/view/yourpage.jsp"/>
</action>


public class MyAction {


 public ActionForward execute (ActionMapping mapping,
         ActionForm actform,
         HttpServletRequest request,
         HttpServletResponse response) throws Exception { 

                 ...

  return mapping.findForward("success");

 }


}

Was my explanation clear ? :-) 不明点御座いましたら、遠慮なくきいて下さい～
