problem in EL

[subodh gupta]

Hi all,

I am trying to compare the string literal in jsp through EL and jslt core library now:

 ${sessionScope.pageType} 

above expression is evaluating as adjust
.

But

 <c:if test="$sessionScope.pageType == 'adjust'">.....</c:if>  

is evaluating as false can you help me.

You are missing curly brackets :

${sessionScope.pageType == 'adjust'}

Hi,

I think <c:if> tag doesn't accept the expression with {} but you have to put like this(like given in the 1st post).

If i put a {} in the test attribute, jsp is throwing exception: expression is not allowed in the test attribute.

what uri are you using in the taglib directive of the page?
Can you post it?

Also check the tld file, i suspect the rtexprvalue tag is not
present for the attribute or set to false.

This means that you are using the wrong version of the JSTL for the version of JSP that you are using.

The exception is:

 
[B]org.apache.jasper.JasperException: /pages/tm/mtm/mtmAdjustQuery.jsp(30,3) According to TLD or attribute directive in tag file, attribute test does not accept any expressions[/B]

Url:

<%@ taglib uri="http://java.sun.com/jstl/core" prefix="c" %>

The version i am using is jstl-1.0.2.jar.

Did you read my reply?

[subodh gupta]

What does this mean?

are the jstl and jsp version not compatible?

i am using jstl-1.0.2.jar and <!DOCTYPE web-app PUBLIC
"-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
"http://java.sun.com/dtd/web-app_2_3.dtd">

this is my web-inf.xml version i.e. 2.3.

So do you think i should try with 1.1 jslt?
