Oracle's Sun Java SE 6, a.k.a Java 1.6, is the preferred version to use with the Sakai CLE, because it has been tested the most thoroughly. Java SE 7, a.k.a Java 1.7 should also be compatible. Certain files, such as *.jsp and *.jws, require compilation so downloading and attempting to use only the JDK, the JRE with only the run time environment (JRE 6.0 or JRE 7.0) will not suffice.

If you find Sun's version and naming conventions confusing, see Sun Java SE Naming and Versions for an outline of their practices.
