Could you please clarify the following :

1. Which version of JSTL are you using ?
2. Where did you get standard.jar from ?
3. What is your container ? If Tomcat, which version ?

[Shashi Prakash]

hi ,

I am using 1.1.2 of JSTL..
I downlaoded it from http://www.apache.org/dist/jakarta/taglibs/standard/
and tomcat version is 6.013.....

OK. In your JSP file, can you show how you declared your taglib ?
