Hi!
I'm a newbie trying to use struts. I'm just trying to set a parameter
to the "request" object, but won't work. Can anyone tell me where I
made my mistake?
I have a System.out.println and it prints alright, but the message never
arrives to the jsp page, the default value is printed instead.
This is from my struts-config.xml
---------------------------------
<form-beans>
<form-bean name="pepitaForm" type="test.PepitaForm"/>
</form-beans>
<action-mappings>
<action
path="/pepita"
scope="request"
type="test.PepitaAction"
name="pepitaForm">
<forward name="success" path="/pages/pepita.jsp"/>
</action>
</action-mappings>
----------------------------------
This is PepitaAction:
---------------------
public final class PepitaAction extends Action {
public ActionForward perform(ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws IOException, ServletException {
PepitaForm pform = (PepitaForm) form;
int base = pform.getBase();
int exp = pform.getExp();
try {
String strMessage = base + "^" + exp + "=" + Math.pow(base,exp);
System.out.println(strMessage);
request.setAttribute("message", strMessage);
return (mapping.findForward("success"));
}
catch (Exception e)
{
request.setAttribute ("message", e.getMessage());
return (mapping.findForward("failure"));
}
}
}
--------------------
This is pepita.jsp:
-------------------
<%@ taglib uri="/tags/struts-bean" prefix="bean" %>
<%@ taglib uri="/tags/struts-html" prefix="html" %>
<[EMAIL PROTECTED] contentType="text/html"%>
<html>
<head><title>Pepita</title></head>
<body>
<br>
<bean:parameter id="strMessage" name="message" value="No value was
specified" />
<%=strMessage%>
<br>
</body>
</html>
-------------------
Please, tell me where did I mix everything up.
Love,
Margarita.
