Hi all,
I can't get started with the example about using LookupDispatchAction of Ted
Husted, Tip #3 (http://husted.com/struts/tips/index.html).
What is my error or can I get some working code ?
This is the problem:
++++++++++++++++
The forward
<html:link forward="testit" styleClass="menuitem">test it</html:link>
gets
ERROR DispatchAction:220 - Request[/test] does not contain handler parameter
named 'method'. This may be caused by whitespace in the label text.
Altering the global forward 'testit' to
<forward name="testit" path="/test.do?method=button.add"/>
gets
javax.servlet.ServletException: Action[/test] missing resource 'button.add' in
key method map
org.apache.struts.actions.LookupDispatchAction.getLookupMapName(LookupDispatchAction.java:240)
org.apache.struts.actions.LookupDispatchAction.getMethodName(LookupDispatchAction.java:281)
org.apache.struts.actions.LookupDispatchAction.execute(LookupDispatchAction.java:158)
org.apache.struts.action.RequestProcessor.processActionPerform(RequestProcessor.java:419)
org.apache.struts.action.RequestProcessor.process(RequestProcessor.java:224)
org.apache.struts.action.ActionServlet.process(ActionServlet.java:1194)
org.apache.struts.action.ActionServlet.doGet(ActionServlet.java:414)
javax.servlet.http.HttpServlet.service(HttpServlet.java:689)
javax.servlet.http.HttpServlet.service(HttpServlet.java:802)

This is the code
+++Action
public final class MyAction extends LookupDispatchAction {
private static Log log = LogFactory.getLog(MyAction.class);
protected Map getKeyMethodMap() {
Map map = new HashMap();
map.put("button.add", "add");
map.put("button.delete", "delete");
return map;
}
public ActionForward add(ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws IOException, ServletException {
// do add
log.info("--- in add()");
return mapping.findForward("success");
}
public ActionForward delete(ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws IOException, ServletException {
// do delete
log.info("--- in delete()");
return mapping.findForward("success");
}
}
+++Form:
public final class MyForm extends ActionForm {
private String prop;
public String getProp() {
return prop;
}
public void setProp(String prop) {
this.prop = prop;
}
}
