How can I invoke the validate() method in DispatchAction

[rocie <ro...@yahoo.com.cn>]

hello,

   Here is my code :
-----------------------struts-test-conf.xml-----------------------
    <form-beans>
     <form-bean name="testForm" type = "goni.test.Test" />
    </form-beans>

   <action path="/test" type="goni.test.TestAction" name="testForm"   scope="request"  parameter="op"> 
    <forward name="home" path="home" />
    <forward name="pre_insert" path="pre_insert" />
    <forward name="pre_update" path="pre_update" />
    <forward name="list" path="list" />
    <forward name="get" path="get" />
   </action>

-----------------------TestAction-----------------------
public ActionForward home(ActionMapping mapping, ActionForm form,
            HttpServletRequest request, HttpServletResponse response)
            throws Exception {
        //...
        return mapping.findForward("home");
    }
public ActionForward pre_insert(ActionMapping mapping, ActionForm form,
            HttpServletRequest request, HttpServletResponse response)
            throws Exception {
        //...
        return mapping.findForward("pre_insert");
    }

    public ActionForward insert(ActionMapping mapping, ActionForm form,
            HttpServletRequest request, HttpServletResponse response)
            throws Exception {
        //...
    }

    public ActionForward pre_update(ActionMapping mapping, ActionForm form,
            HttpServletRequest request, HttpServletResponse response)
            throws Exception {
        //...
    }

    public ActionForward update(ActionMapping mapping, ActionForm form,
            HttpServletRequest request, HttpServletResponse response)
            throws Exception {
        //...
    }

    public ActionForward delete(ActionMapping mapping, ActionForm form,
            HttpServletRequest request, HttpServletResponse response)
            throws Exception {
        //...
    }

    public ActionForward list(ActionMapping mapping, ActionForm form,
            HttpServletRequest request, HttpServletResponse response)
            throws Exception {
        //...
    }

    public ActionForward get(ActionMapping mapping, ActionForm form,
            HttpServletRequest request, HttpServletResponse response)
            throws Exception {
        //...
    }


The TestAction extends the DispacthAction , and the Test extends the ValidateForm. I can use test.do?op=pre_insert to show a jsp page with a form and if it is submitted, the test.do?op=insert will be execute,the validate() method will be invoked ,then the data in the form will be inserted into the database.If I execute the insert and update methods , the validate() method will be invoked,I wish when I execute the other methods , the validate() won't be invoke, how to ? 

thanks!
