Redbook sample SimpleGridBagLayout error

[Peter Sharp]

G'day,
I've installed the NrxRedBk.zip package as per the instructions, built the
\NrxRedBk\Redbook & gui\SimpleGridBagLayout classes successfully, & updated
the CLASSPATH.  But I get the following error when I attempt to run it:

Any clues?

I remembered an earlier comment re- NoClassDefFoundError for which the
solution was to copy tools.jar into the jre\lib\ext directory due to a
change in behaviour from earlier jdk's (I'm using java 1.4.2).
Unfortunately, copying the Redbook\ directory to jre\lib\ext did not work,
but copying the contents of the SimpleGridBagLayout dir to the home
(NrxRedBk\) dir & running from there did the trick.  So, it seems it's
necessary to be aware of the changes in behaviour from the v1.1.1 jdk that
the Redbook samples were developed & tested for, compared to later jdk's, &
to compensate accordingly.

I haven't looked at/tried the example, but it sounds as though the
classpath is either wrong or you are invoking the sample from the
wrong directory?
