Trying to use HTML values in JSP

Hi, I have a problem using a HTML value in my jsp page.

It doesn't work. I tried to do this before:

But I can't use parseInt like this. Can somebody help me?

I have a list ("nodoak") object where I have my "nodo" objects, with some atributes. I want use that HTML value to show a nodo or another. And then I want to change the value of the HTML node and reload the page.

Error with JSP: Doesn't work with my object, it does with a String

Looks like you are missing the jar file for JDOM.

I've got it in the build path, I added as a external JAR with Eclipse.

I use JDOM for extracting information from an .xml document in a method in the Nodo class. I tried supressing it and it works! So I have to do something with that .jar because in the moment of the building something goes wrong. Can someone help me?

Bear Bibeault, thank you very much, really.

Error with JSP: Doesn't work with my object, it does with a String

I'm reediting: It's a Maven project and I have to add a external file to the repository.

I'm explaining what happened. The class Nodo had a method that uses JDOM library, and it was failing. That's why it worked with a string, a string doesn't use that library. Now I have supressed that method and it works, but I still need that method. Do you know how can I make it work? As I say down here, I use Springsource Tool Suite (eclipse) and I had added the jdom.jar file as a external jar in the build path.

Hi guys,
I hope you can help me. I'm creating an easy MVC web app with Spring Framework (using STS) and I'm having problems with JSP.

I have a jsp page where I want to show some properties of my object "Nodo", but I'm getting this error:
