You should look at the source code for the version of DispatchAction and
LookupDispatchAction (available either from a download of src or the cvs
repository). Older builds just threw an exception if LDA didn't find a
parameter for method. You can overide the execute() but you might just
as well write your own action. DispatchAction works differently. Newer
builds of struts have modified the behavior of LDA.
besides it is sort of fun to see how the things actually work.

You know I was just thinking about doing "/foo.do?method" when I read your
post. I stuck it in there, but that didn't work.
Then I tried "/foo.do?method=" and "/foo.do?method=label.modelBrowse" and
"/foo.do?method=model". Now it executes the 'unspecified' method no matter
what I do, even if I click on one of the buttons...

With the stable release of 1.1 you need to pass the parameter through
usually
/foo.do?method=save
but to get the unspecified method running
/foo.do?method
suck it n see.

Yeah, I have basically that code for the submit buttons.
Isn't the 'unspecified' method of the LookupDispatchAction used to
handle
this issue though? I thought that's exactly what it's purpose was,
but the
method is not getting executed as I expected it to.
Very frustrating...

Most likely the "browseType" parameter is not defined in you page, so
it is
not submitted.
If you're using the struts submit buttons, you probably have something
to
the effect of:
<html:submit property="browseType">
<beanMessage key="someKeyName"/>
</html:submit>
The effect of the button tag is that when it is clicked, the
"browseType"
parameter will be added into the request. When the button is not
clicked,
the "browseType" parameter is not added into the request. If I
remember
correctly, we had to implement a handler to listen for the enter key to
make sure that our parameter was added to the request.

Hmmmmm....
It's not working for me. I have a form with 4 different submit
buttons.
I'm trying to get it to execute the 'unspecified' method of my
LookupDispatchAction when the user presses 'Enter' rather than
clicking on
a
button.
Right now I have:
public ActionForward unspecified(ActionMapping mapping, ActionForm
form,
HttpServletRequest request,
HttpServletResponse
response)
throws Exception
{
System.out.println();
System.out.println("'Unspecified' Method executing...");
System.out.println();
return modelBrowse(mapping, form, request, response);
}
But when I press 'Enter' after filling in the form, my output doesn't
get
written to the console and I get an error that says:
javax.servlet.ServletException: Request[/Browse] does not contain
handler
parameter named browseType
Does anyone know what I'm doing wrong or how to fix this? It works
fine
when I click on a button, but not when I press 'Enter'.
Thanks!

Hi All!
Just went through the source code.
This problem can be attacked by overriding the method unspecified(...)
===========
public ActionForward unspecified(
ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws Exception {
===========
Thanks,

Hi All!
I was wondering if it were possible to have a "default" method called
when
there is no parameter matched or the parameter is null.
TIA,
Kunal
