Issues about Deploying Jersey RESTful Web Service On OpenJDK-based Tomcat Server

[Wei Song]

Hello,  

I've developed a RESTful web service and a JSP/Servlet web modules at Windows, Eclipse, Java EE environment. When I tried to Deploy them on a OpenJDK-based Tomcat 6 server on Ubuntu, I always got the exception: 

javax.servlet.ServletException: java.lang.UnsupportedClassVersionError: cs/turtlesback/bean/UserBean : Unsupported major.minor version 51.0 (unable to load class cs.turtlesback.bean.UserBean) 	org.apache.jasper.servlet.JspServlet.service(JspServlet.java:268) 	javax.servlet.http.HttpServlet.service(HttpServlet.java:717)

The details of my development environment:  
Windows 7 
(Oracle ) JDK 1.6.0.32 
Eclipse Java EE Indigo 
Apache Tomcat 6.0.35 
Jersey 1.0.3 (asm-3.1.jar, jackson-lgpl-0.9.4.jar, jersey-client-1.0.3.jar, jersey-core-1.0.3.jar, jersey-json-1.0.3.jar, jersey-server-1.0.3.jar, jettison-1.0.1.jar, jsr311-api-1.0.jar)  
MySQL 5.0

The target deployment environment: 
Linux Ubuntu 10.04.2 LTS 
Java version "1.6.0_20" 
OpenJDK Runtime Environment (IcedTea6 1.9.13) (6b20-1.9.13-0ubuntu1~10.04.1) 
OpenJDK Client VM (build 19.0-b09, mixed mode, sharing) 
Apache Tomcat 6.0.24 
MySQL 5.0

Could you give me any suggestion for solving the problem?   


Thank you.
