Hi, I am using tomcat 4.1.31 which supports JSP 1.2 I wrote a JSP : <%@ page isELIgnored="false" %> <HTML><BODY> ${param.name} </BODY></HTML> I have done following entry in web.xml <jsp-property-group> <url-pattern>*.jsp</url-pattern> <el-ignored>false</el-ignored> </jsp-property-group> While running the JSP with above mentioned page directive the container throws an exception saying that Page directive has invalid attribute: isELIgnored When i remove the page directive. The output is on the browser is simply the string ${param.name} As the container gracefully accepts the entry in DD. It is doubtless that the container supports EL. Can someone tell what am i missing? and what should i do to enable the EL and get the desired output ?? -------------------------------- Regards, BM. SCJP 1.4 - 98% SCWCD Preparing....

I came across similar problem before. I can't explain why, but it seems to related to version of JSTL. The one I came across is: On old tomcat (v4.X), the uri is something like uri="http://java.sun.com/jstl/core", I can't use EL such as ${param.userName}, it only print out same thing, not value (just like EL is ignored), to output the value I have to use <c ut value="${param.userName}" /> However for Tomcat V5.5 (didn't try 5.0), the uri is "http://java.sun.com/jsp/jstl/core", it works on opposite way: It won't take <c ut value="${...}"/>, exception will be thrown and said "the taglib said won't take ${} for c ut value), but it works perfectly when you only use ${param.userName}: it output only the value

Hello Friends, I think EL is part of JSP2.0 spec. Try download tomcat 5.0.28 or greater ones and try FOR JSTL Tomcat 5.0 > onwards you need not web.xml entry to locate tld. Just placing the standard.jar and jstl.jar in lib directory of ur webapp will solve

Hey Karthik, if EL had been a part of JSP 2.0 then container would not have accepted the DD entry related to EL.
