I have a WAR file which I am trying to deploy and run on a Tomcat 7 server with JVM 1.6. I receive the following error HTTP Status 500 - : Unsupported [url removed, login to view] version 51.0 (unable to load class)
The file works fine on Tomcat 7 with JVM 1.7. I need it working with the new server. Upgrading JVM from 1.6 to 1.7 is not an option.
Need the WAR file redeployed on the new server and functioning.
Other option would be to deploy the WAR file on a new OpenShift server and get it running.
