[Bluej-discuss] BlueJ and the Eclipse compiler

[Stephen Gilbert]

Hi,
Thanks, both of you. I didn't know that BlueJ was using other features from
the JDK, other than the compiler from tools.jar. Our machines all have the
JRE
(which includes all of the Java libraries) and it's always been kind of
difficult to explain
to students why they need the JDK as well, especially since Eclipse (and the
command-line Eclipse compiler) seem to work without it.
Thanks very much for the info.
