Yes. I've just managed to get this working. I can now invoke
the servlet and pass in the parm values trailing it.
Just a Q since I have you though. When I use req.getParameters()
to get the parameter string here it just comes back as one big
string. So I'll have to parse the parameters out manually right?
Thanks.

Subject: Re: Invoking a servlet via a hyperlink
I might be way off here (since I don't use this approach); but, can't you
just say
<a
href="servlet/controllerServlet?name=RetrieveVendors.do¶m1=value1..">Hyp
erlink</a>
This should definitely invoke the controller servlet with all the right
parameters.
