Answer 1

Differences among different major versions of java (1.5 - 1.6 - 1.7) include differences at the compilation step. Therefore if an application has been compiled for Java 1.7, you cannot run it on a Java 1.6 Virtual Machine.

In order to do what you want, you will need the source recompiled for Java 1.6. If it can be compiled for 1.6, it is quite likely to run on 1.6 and 1.7.
