Compiling java 7 for java 6 with Eclipse

I need to compile a project for Java 6 to use with java 6 or 7 (I can't upgrade all of the computers in my life). I've been searching all over and found somewhat helpful stuff, but I'm rather new to java - I don't understand much of how to use the presented alternatives (ant-build, Maven, javac).

My program does not use any API methods that are not available in Java 6, but it does use the API of another external .JAR (it is a basic plugin for an example program)

Is there a simple way to do this with Eclipse's Export function, or do I need to use some other program/method?

If I need to use something other than Eclipse, how would I best go about doing it for a multi-class, multi-package file dependent on another external .jar's API?

In Eclipse Juno SR1: right click your project -> Properties -> Java Compiler -> Compiler compliance level.

Set that to 1.6 and you're done. You might need to enable project specific settings and disable compliance with execution environment - 2 checkboxes in the same window.

Right-click on your project in eclipse and open the project properties.

Then navigate to Java compiler and set the compliance level to 1.6.

That should do it.
