yeah, that's exactly it... of course you need to check it's not null and
it will always be a string. If you want a number you'll have to parse it
into an integer (or double) yourself.

Thank you all, that's what I'm looking for. Sorry about the confusion but
this is my first time using velocity, but how to do you tell the servlet
to pick up the URL parameter? If I have this parameter in my velocity
template $number, and parse it to URL http://server.jsp?number=something,
will the servlet just recognize this parameter if I assign a variable say
String number = request.getParameter("number")?

Re: How to pass values between velocity and servlet
If you're using a hyper link to a servlet, can you add the parameters
with the URL? You can save whatever information you need to pass to
Velocity from the current session as a session attribute. As long as
the servlet is in the same web application, the session attributes
will be there. Tomcat also lets you share session attributes among
applications within the same instance of Tomcat.

if
users don't use the form. But I can't put it in a separate form
either...

Re: How to pass values between velocity and servlet
can you not just use the same form - just add a hidden field!

Hi,
I have a parameter on a velocity template which I need to pass to my
servlet to do some calculation, and then pass it back to the velocity
template for rendering new content. I'm already using a form filter
through HTTPRequest so I cannot use another form to pass on the data.
The
idea is to make it a hyperlink instead. Is there a way to do it
without
sending it through a form? Thank you.
