I am not 100% sure, but I am under the impression that what you are talking about here 
can only be done with containers supporting JSP 2.0 (tomcat 5 for example) since this 
JSP version has Expression Language support, and perhaps it is not possible with 
tomcat 4.x. Or it might probably be possible, but not with this syntax at least. You 
would probably have to write some more complicated code to achieve the same result 
(i.e. carry on your values). 

Possible solutions are to ask your provider to give you tomcat 5 support or change 
provider. You can download tomcat 5 locally and give it a go to see if it does 
actually what you want, I think it does.

  Hi Martin,
    Yes I want to be able to carry on my values using
  ${param.my_variables_name} in tomcat 4.0.3 and using taglib 1.0. What
  uri would I use? I don't think the core_rt will work, but I would like
  the same functionality and I can't change tomcat versions because I'm
  uploading to a web service provider.
