Subject Re: How to pass values between velocity and servlet
Date Thu, 12 Oct 2006 15:47:10 GMT
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.

http://server/app?parameter=something
