Hi Elias,

I think signing your applet will do the trick.

I don't know why JPlotLayout need security access but signing your applet
will work.

Regards,
Laurent.

Objet :     JPlotLayout in JApplet

Hi List,

I've written a program that uses JPlotLayout for plotting.  The main
class is written to be used as a standalone Java application or as an
applet.  It works well as an application but when loaded as an applet
(with appletviewer, Sun Java 6) it fails with an
ExceptionInInitializerError (complete error message below).

The line that causes the error is where I create the JPlotLayout:

         plot = new JPlotLayout(JPlotLayout.LINE, false, false,
                                yLabel + xLabel, null, false);

I guess JPlotLayout is trying to do something an applet is not allowed
to do.  Is there anything I can do about this?  Is it known to be
possible to use JPlotLayout in an applet?

The complete error message is (the class that creates a JPlotLayout is
"FuncDraw"):

Thanks in advance for any help,

 Elias Assmann
