Hi Rajan,
I'm assuming that you are running in an applet, right?
The problem is that bringing up a new window in an applet is tricky.
I believe it can be done, I've run an applet and seen a window that
says "This is an applet".  However, a long standing problem with
our current infrastructure and applets.

There are a couple of solutions:
1) Use Web Start (JNLP).  This gives the user a better experience,
they have the full application installed.  Sun is moving away from
applets towards Web Start.  Later versions of Java 1.6.0 (after u10?)
have some interesting applet/Web Start infrastructure.  I'm working
on tool that semi-automatically creates Web Start configurations.

2) Use something like ptolemy.vergil.MoMLViewerApplet or
ptolemy.actor.gui.MoMLApplet.  This would require extending
this code to use Kepler.  There might already be applet code in
Kepler, I did not look

3) Use some of the web-based work like Hydrant, see
https://kepler-project.org/developers/interest-groups/webui

Looking at your problem error message, I suspect that there is no
ptolemy.actor.gui.Configuration.
