Here's what is probably happening...

While you've installed Java 1.6, your JAVA_HOME and/or your PATH
variable is/are incorrectly set. They're pointing to an earlier
installation of Java 1.4. This is why java -version is getting you an
older JRE.

Second, if you're installing Eclipse as appears obvious, be certain to
download jdk1.6.0_22 NOT the more public/consumer thing called a JRE.
You will want the JDK.

You may or may not install the JDK on your machine and you do not have
to install it for Eclipse--just download it someplace and point to it
from eclipse.ini.

If you would like to read more in-depth on this, peruse the first
article or two under the heading "Eclipse-oriented" at

Also, please pay attention to the "sticky" posts at the top of this
forum group. There is one that specifically says "Can't get Eclipse to
run? READ THIS"
