Solving “According to TLD or attribute directive in tag file” issue

Yesterday while working on one of the old web application that was created in J2EE / JSP which is using JSTL for painting pages, I encountered a wired issue. As I was using JSTL in my JSPs, I had include required jars like standard.jar and jstl.jar with proper version in classpath of my project. Still I was getting this error whenever I tried running JSP:
According to TLD or attribute directive in tag file, attribute value does not accept any expressions.
After digging into the issue and searching through web, finally I got a workaround to solve this issue. The taglib directive we use to include JSTL core in our JSP needs to be modified. The taglib in my JSP was:
<%@ taglib prefix="c" uri="" %>
Code language: HTML, XML (xml)
I changed above to:
<%@ taglib prefix="c" uri="" %>
Code language: HTML, XML (xml)
And it worked for me!!! I dig into standard.jar for any clue and also checked few .tld files in this jar but couldn’t find an explanation for this. Any idea why this is so?

  9. Tharakaram says:

    This is due to missing of under . This is used to specify the tag accepts EL expression to resolve value. By default its false. so if you want use dynamic EL
    expression for your attribute then you need to define tag value as ‘true’.

    Thanks for this. It helped me. as to why this is actually so, compare the following two fragments:

    before, we were using the tld (file: META-INF/fmt-1_0.tld) which had:


    but now with “… _rt”, the attribute bundle is defined in META-INF/fmt-1_0-rt.tld as follows:

    Excellent solution. Just now I had this problem with Apache Tomcat 7.0.11 and was badly surprised of it, because under Tomcat 7.0.42 all goes right without “_rt”.

  44. Gregory says: 

    says “the two libraries differed in that one would allow run-time expressions as tag attribute values, and one wouldn’t.”

  45. Prasad says:

    Thanks this helped.

    I checked further on the TLD files in the JAR. The older version of TLD file has been renamed and if you look at the URI you should see it as
