Tom--
If your users are running as applets, why not run your server as a servlet?
Does it need to hold state information across the entire userset, or is
each user interaction stateless?
What I'm suggesting is something like this: create a number of different
servlets to perform each task ("AddF

I know Joe Burks posted a fix on how to get this to work, but it didn't
work for me; I'm sure it's some Linux-configuration thing that's keeping me

Your import statement (in your teste code) must be wrong; otherwise, java
would pick it up.
To determine if its a CLASSPATH issue, try this:
javax.swing.tree.DefaultTreeModel model = new
javax.swing.tree.DefaultTreeModel(root);
That'll tell you if you left out the import, got the import wrong,

Look, here's my bottom line: With Power Comes Complexity. Perl is simpler
than Java, Java is simpler than C++. With that simplicity you lose a
corresponding amount of power. But the end result is that it doesn't

I don't think so, unless you're running as an applet--the
AppletSecurityManager disallows ClassLoaders of all forms.

Somebody made mention, in the JavaSpaces list, that if you want to do
JavaSpaces (which uses Multicast sockets, as I understand it), that you have
to have multicast support compiled into the kernel.
It's hearsay and rumor, but maybe it'll help?

No--don't do that. DON'T convince yourself that
you need to avoid using a particular language feature "because of its
impact on performance". Use the language feature, profile the app, THEN
worry about performance. There are dozens of things you can do to better improve
app speed (including

Look in the src.jar file, under launcher.java.c; it's coded explicitly in
there. launcher/java.c is the standard Sun boilerplate for all of the
"native" tools in theJDK (javac, java, ...).
