java.lang.NoClassDefFoundError: javax/servlet/jsp/jstl/core/ConditionalTagSupport

While I am deploying and runing my web application on Apache Tomcat in Eclipse IDE

I've included the JSTL1.2.jar, jstl-impl.jar.

I'm really wondering how to get this fixed. The same deployment works perfectly fine on Weblogic server(on PROD environment)

Exception stack trace:

I would check a number of things:

1) That the jar files are sitting in the lib folder under WEB-INF and not just referenced in the build path. 2) That the tomcat 7 runtime library is included in your build path 3) I'd check the web.xml file and ensure that I'm complying to a spec higher than or equal to 2.5.

If you provide more details with your project setup it might be easier to answer.
