Hi Brian,
That error message is from Tomcat, which doesn't know it is being
invoked from Eclipse and JAVA_HOME doesn't apply. In the Servers view,
double-click on the Tomcat 4.1 server. In the server configuration
editor, click the "Edit" link to the right of the Runtime field.
Make sure what is selected in the JRE field is actually a JDK. This
error suggests that the current selection is just a JRE, since this is
the Java runtime that will be used to run Tomcat.
Cheers,
Larry

I also had this problem a few days ago.
Another way to solve it is to give tomcat a copy of the tools.jar, which
is the jar where the javac is. Or you add the location of tools.jar to
your CLASSPATH.
cheers,
