Hi,
at first my code.
my DispatchAction-Class:
public class ExampleAction extends DispatchAction {
public ActionForward delete(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse
response) throws
Exception {
System.out.println("******* delete");
return mapping.findForward("continue");
}
public ActionForward add(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse
response) throws
Exception {
System.out.println("******* add");
return mapping.findForward("continue");
}
}
my jsp:
<html:html>
<head>
</head>
<body>
<html:form action="/ExampleSubmit">
<html:submit onclick="this.form.method.value='delete'">
</html:submit>
</html:form>
</body>
</html:html>
and the part of the struts-config.xml:
<action path="/ExampleShow"
type="org.apache.struts.actions.ForwardAction"
parameter="/jsp/Example.jsp"/>
<action path="/ExampleSubmit"
type="ExampleAction"
name="exampleForm"
scope="request"
input="/jsp/Example.jsp"
parameter="method">
<forward name="continue"
path="/jsp/Example.jsp" redirect="true"/>
</action>
When click of the button, I get this error:
----------------------------------------------------------------------------------------------------------------------------------------
javax.servlet.ServletException: javax.servlet.ServletException:
Request[/ExampleSubmit] does not contain handler parameter named 'method'.
This may be caused by whitespace in the label text.

It is working if I type manualy ExampleSubmit.do?method=delete
(The delete-method in the action-class ist calling)
It is also working with this submit-button:
<html:submit property="method" value="delete"/>
But why doesn't work <html:submit onclick="this.form.method.value='delete'">
</html:submit> ?
This should be the same like in this example:
