importing jena in java

[vijayalakshmi]

I have deployed a java servlet in tomcat6.0. I am unable to use jena
libraries in the servlet.

I tried placing the JENA JAR files inside  both     $tomcat/WEB-INF/lib
   and          $tomcat/WEB-INF/classes/

I also tried setting the classpath to $jena/lib in control
panel->system->advanced->environment variables

but i am getting the following errors.
