html:form and ForwardAction

[Matt Connors]

In my .jsp I have:

<html:form action="Welcome">
...

The corresponding ActionMapping in my struts-config file is as follows:

<action path="/Welcome"
type="org.apache.struts.actions.ForwardAction"
roles="employee"
parameter="page.welcome"/>

When I run the .jsp I get the following error:

javax.servlet.jsp.JspException:
Cannot retrieve definition for form bean null
at org.apache.struts.taglib.html.FormTag.lookup(FormTag.java:831)

It appears that Struts does not allow me to use an ActionForward as the target of the <html:form action= ...>.
I believe I am receiving the error because the action mapping
"<action path="/Welcome" ...." does not have an ActionForm associated with it.

Is it possible to use an ActionForward as the target of an <html:form ...> statement? Is there an easy way around this?

I don't want to change the ActionForward to a full-fledged ActionMapping because it's Action class and its ActionForm would not do anything functionally.

Any suggestions would be appreciated.

Thanks,
Matt

I don't know that you're supposed to do things that way. You could possibly use that and pass the page parameter as on the url with a javascript location forward?

eg.

 
<script>
  function doForward(page)
  {
    // using rewrite guarantees always having the correct url
    location.href='<html:rewrite page="/action/Welcome" />?param=' + page;
  }
</script>
 
<a href="javascript: doForward('grab page name from somewhere');">Go!</a>
 

Failing that maybe logic:redirect would be of some use?

Hope this helps!

Hi matt

I am not able to understand the reason why u r going for <html:form> with out havig a formbean attached to it and that too the strange thing is that u r using the default ForwarAction ......this forweardatcion will be used when u want a link to be tranferred to jsp and then u should not violate MVC and that too the primatry reason why u r getting that exception is <html:form> will always look for formbean attched to it to render the name attribute of ur form which is missing in urs
