I was quite annoyed by the fact that you can’t just call a method with certain parameters using JSTL. Lucky me, google gave me a result where I could see how this is done (using JSP 2.0).

The thing is, you need to create a static method with the required parameters and then you need to define a TLD to be able to call the function. This process can probably be simplified by using a tool like XDoclet so your TLD is generated automatically, but I didn’t look into that, yet.

Another way to do it is described by Lucas Jellema on the AMIS blog. But I don’t call this a real solution, just a very dirty hack. I respect him for his posts on Oracle, but I don’t like this solution at all.
