My web.xml seems fine. I changed the JRE in the build path to 1.6 from 1.7 to check if this is a version issue. Can anyone identify what the issue is and suggest possible solutions?

Looks like you are bundling servlet API in your webapp. You should not do that — gpeche, Dec 12 '13 at 22:41

You compiled your application with newer version of Java (then one available on your server).

Double check what version of Java is used by your local Eclipse and remote Tomcat.

I changed it to java 1.6 from 1.7 . Im still having this issue. – DJR Dec 12 '13 at 21:49
Unsupported major.minor version 51.0 - this means that class was compiled with Java 1.7. Did this exception text changed after you moved to Java 1.6? – pksiazek Dec 12 '13 at 21:58
You can use: "javap -verbose User.class" to verify that without deployment – pksiazek Dec 12 '13 at 22:05
After changing the java, i cleaned the project and re built it. It still gives me the same error. Should i run the above command in eclipse folder at command prompt? – DJR Dec 12 '13 at 22:21
In folder with this problematic class (User.class) - but compiled class not java file – pksiazek Dec 12 '13 at 22:31
