JSTL problems

Question

Hi,
          Just started using WebLogic 10, and have a problem using JSTL in my JSP pages.
          After deployment with no errors, I get the following error when I try to access the .jsp page... I have tried to put the .jar files JSTL needs in the domains \lib folder, and also included it in the .war file in the WEB-INF\lib folder. The .war file is working on the Sun appserver.
          No tag library could be found with this URI. Possible causes could be that the URI is incorrect, or that there were errors during parsing of the .tld file.
          <%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>

Answer 1

You're certain that you have the correct JSTL jars in WEB-INF/lib? There is a set of versions used with JSP 1.2, and a set of versions used with JSP 2.0. You need the newer versions. Typically, version 1.1.x is used with JSP 2.0. You could verify this by opening up the jstl.jar file and the enclosed TLD file and verifying that the URI in that file matches the URI that you're using.
          You could try setting "prefer-web-inf-classes" to true in your weblogic.xml.
          This probably isn't relevant, but are you referencing the Servlet 2.4 schema in your web.xml, as opposed to the Servlet 2.3 DTD?
