Unsure if I am using the correct version of Java for Eclipse

I am having a bit of trouble determining if I am running the correct version of Eclipse and/or Java. I am attempting to make changes to a JAXB program for work. I can't run the program and an error is generated that states 

java.lang.UnsupportedClassVersionError: RunISOPaymentFileSimulator : Unsupported major.minor version 51.0

I know from doing my research using the search function this means that I need version J2SE 7.

After searching for my current version I find that I have Java 6 Standard Edition build 1.6.0.

My question is this: Is Java 6 the same thing as J2SE 6? Do I need to just update my Java version to 7 or do I need to also find the special J2SE 7?

Thanks very much!

Neither Java not J2SE is specific enough. What you need is the Java 7 JRE (Java Runtime Environment.) You probably already have it but your JAVA_HOME is set to 6. Changing your JAVA_HOME can cause issues for some applications that are written poorly so be prepared to have to switch it back.
