Unsupported major.minor version 51.0 error after moving from IntelliJ IDEA JBoss to MyEclipse Tomcat

Question

I am getting a Unsupported major.minor version 51.0 error after moving from IntelliJ IDEA JBoss to MyEclipse Tomcat.

Everything was working great under IntelliJ IDEA

Answer 1

You can set the compiler version here:

Project -> Properties -> Java Compiler
