My application server was using JSP 2.4 and i was using an incompatible version of JSTL. The table you have come up with is helpful. You saved me a lot of time with this well written information. I appreciate your time and effort. Thanks very much. Keep it up :) ! Cheers, Amith Nambiar Really helped in fixing my problems with JSTL.

I can't believe they changed the url, because there are so many websites that still say to use the old URL and it caused me so many issues. Thankyou so much for this info!

None of my EL expressions were evaluating. Turns out it was the web-app tag in the web.xml. Thanks for the article. None of my EL expressions were evaluating.

I do find that the books that I read sometimes feel out of step with the developer forums. I am trying to raise my proficiency at J2EE development and am focusing on JSP. The other widely used presentation tool seems to be ASP, which I am allergic to. Do you think JSP is on the rise? Or on the decline? I really was not sure how to take your comments. I also get the impression that nobody refers to "EL", it being merged or overtaken by JSTL. Is that correct? Thanks!

I would be interested to see your tests performed with Unified Expression Language. I've seen example where they claim you can place #{} references anywhere on the page, but whenever I try that I get an error about including deferred values in template text. I'm using servlet 2.5, JSP 2.1 (apparently glassfish 2 supports this, but this error doesn't seem to indicate that) and JSTL 1.2. Looking at glassfish I found multiple jars containing JSTL implementations and the TLD doesn't have tag atributes that can handle deferred values as per the examples. Also, accessing the nested variable created by the forEach loop isn't accessible using #{} syntax as a number of examples claim. the loop does however iterate the correct number of times with #{} in the items attribute. It appears I have the correct software stack in place, but am now re downloading containers etc to work out is anything has been added to them by my dev tools that have messed with the implementations used. I was originally trying to use JSF managed beans with the JSTL loop tag, but even with plain JSPs have access issues.

There are some heavy-ugly JEE stacks like GF and JBOSS that support it out of the box, but lighter (and more useful) ones like Tomcat and Jetty -- don't even have instructions on how to set JSTL 1.2 up properly. Moreover, JSTL 1.2 jars are nowhere to be found. This is what I did to make Tomcat 6 to "like" JSTL 1.2 -- you basically take appserv-jstl.jar (from either GF or JEE /lib) and "trim" the javaee.jar to only have javax.servlet.jsp.jstl package (otherwise you risk running into conflicts with other JEE crap-libs in Tomcat) and by including these into web app -- you'll have JSTL 1.2. EL is already in Tomcat. On the side note this is of course a dirty hack. I don't have too much JSTL code yet so I might be up for some unpleasant discoveries very shortly. On the side note I think JSTL is the best thing that happened to JSP -- a compromise between simplicity and functionality that makes PHP/Ruby bleak. Look how many custom tag libs spawned on Apache when it was introduced! I have no idea why community and Sun suddenly lost interest and not maintaining this technology anymore. Struts/Spring being "golden handcuffs" and JSF with its complexity being the "EJB for the web" -- Looks like we're going back to plain old JSPs being the only thing you can get some actual work done with (that involves a little more than CRUD functions).
