JSP 2.0 Expression Language not working

[cgreynes]

Hi,

I am learning JSP. I cannot make the Expression Language to work. For example: ${1+1} should equal 2. It turns out it only prints "${1+1}".

I followed the book and I installed SDK 1.4.2 and modified web.xml (see below). Is there anything else I should do?

<web-app xmlns="

http://java.sun.com/xml/ns/j2ee"

xmlns:xsi="

http://www.w3.org/2001/XMLSchema-instance"

xsi:schemaLocation="

http://java.sun.com/xml/ns/j2ee

web-app_2_4.xsd" version="2.4">

Thanks
clark

Hi,

The syntax is <cut value="${1+1}"/>, you need to have jstl core taglibrary and the ref to the lib in your web.xml.

Cheers

I thought I replied back. Maybe I forgot to click the submit button.

Anyways, I am not familiar with JSTL but I have seen a sample code for it. I will use venur's sample code when I reach that chapter.

I encountered this problem when I am using JRun 4 and SDK 1.4.2. Maybe I set it up incorrectly. But it works when using Apache 5.5 and JDK 5.0.
