Have you included the JSTL library?

See the JSP FAQ which covers this in detail.

Jigar, don't feel bad. You should know that all of us have done something like this (ie - forgot to restart the server after changing a web app)at one time or another :-)

No actually there are two lib directories in Jboss

1)D:\jboss-4.0.5.GA\server\default\lib

2)D:\jboss-4.0.5.GA\lib

so i was confused where to put jstl.jar

first i copied jstl.jar in 1)D:\jboss-4.0.5.GA\server\default\lib and restarted the server.. but still it was giving the error.

than at second location 2)D:\jboss-4.0.5.GA\lib

than i dint restart server. it was still giving same error.. but than after 10 mins i restarted server. and it was working fine...

and right now there is no jstl.jar in none of the following location

1)D:\jboss-4.0.5.GA\server\default\lib

2)D:\jboss-4.0.5.GA\lib

but still my application is working fine...

is there any logic behind it ???

Is that packaged in your application war file? in WEB-INF/lib?

And that is why it works. Basically at runtime web server tries to find the library in following order: web server main library (jboss_home/lib), web server particular mode library (jboss_home/mode/lib), then in your application war file (WEB-INF/lib). In fact you should put all java archive files in WEB-INF/lib directory on which your application depends upon.

HTH.
