I am getting this error when i try to implement the DispatchAction class "DispatchMapping[/login] does not define a handler property".

public class LoginAction extends DispatchAction {


public ActionForward add(ActionMapping mapping,ActionForm form,HttpServletRequest request,HttpServletResponse response) throws Exception
{
return mapping.findForward("login1");
}

public ActionForward update(ActionMapping mapping,ActionForm form,HttpServletRequest request,HttpServletResponse response) throws Exception
{
return mapping.findForward("login2");
}

public ActionForward delete(ActionMapping mapping,ActionForm form,HttpServletRequest request,HttpServletResponse response) throws Exception
{
return mapping.findForward("login3");
}
}

I have imported the necessary classes for the same.

My action mapping looks like following
<action name="LoginForm"
path="/login"
scope="request"
type="net.tennet.loginstruts1.actions.LoginAction"
input="/jsp/Login.jsp">
<forward name="login1" path="/jsp/success1.jsp"/>
<forward name="login2" path="/jsp/success2.jsp"/>
<forward name="login3" path="/jsp/success3.jsp"/>
</action>
Now i try to use this code to call the individual methods.
<html:link target="_self" page="/login.do?function=add">Link1</html:link>

and so i get the above error. Any ideas as to why this is happening?

You need to add

parameter="function"

to your <action> tag in struts-config.xml.

This is what tells the DispatchAction Class the name of the request parameter that is to control the logic flow.

Hey !!
If Still is giving error than do one thing...
use action instead of page in <a href> tag..

Because, action tag is more convenient than Page when you are calling an action specifically....

andPage is used when you wnat to forward request to any JSP page directly
