Containers are collections of libs, basically. The JRE_CONTAINER is the
one that contains all the standard JRE libraries, including things like
java.lang.Object.
It was not clear from your previous post if you have tried or been able
to add a new JRE to your Eclipse configuration. (Preferences > Java >
Installed JREs > Add button). You should be able to browse to the JRE
home directory and when you select it Eclipse should fill in the JRE
Libraries box automatically.
Is this what you've tried? If so, what exactly were the results?
