Re: How to pass values between velocity and servlet

[Paul Loy]

well just append it as a get value (1) to each url or add it to a 
session variable(2).

(1) each url (including the one in your forms 'action') will need the 
variable added to it, e.g. http://somedomain/someurl.jsp?somevarieble=xxx

(2) never used this as I have a multi-server environment and sessions do 
not persist across the servers, but if you've only one server you could 
use this option. I don't believe it's too difficult. Look it up in google.

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.

Erica
