Are you using Apache (Jakarta/Tomcat) implementation of JSTL or some 3-rd party one? http://tomcat.apache.org/taglibs.html It should not matter.

Printing "${myVar}" means that EL expression is not recognized, or its textual value is literally "${myVar}". Are other EL expressions working on that page? There exist options that turn off recognition of EL expressions. More details are in JSP specification. Make sure that version and schema path in web.xml are correct. JSTL library has different <%@taglib declaration URLs for JSTL 1.0 and JSTL 1.1/1.2 tags. Make sure that you use the correct one. Look into java code generated for the JSP page for what strings are written out by the page. Is it written literally, or it is evaluated? Are you accessing the JSP page in Tomcat, or directly the source code of JSP page? Iit may happen with misconfigured Apache HTTPD in front of Tomcat. Any unnecessary libs in WEB-INF/lib directory (e.g. a different copy of Tomcat jars pulled in by Maven)? Any unnecessary libs in Tomcat's lib directory? Can you simplify your example, while keeping it reproducible?
