same problem...

Posted by josh on April 29, 2001 at 4:55 PM

I get the same error at the bottom of the java console:

> > ========= error=========
> > java.lang.InstantiationException: HelloWorld

> > at com/ms/applet/BrowserAppletFrame.newInstance (BrowserAppletFrame.java)<
> > at com/ms/applet/AppletPanel.processSentEvent (AppletPanel.java)
> > at com/ms/applet/AppletPanel.processSentEvent (AppletPanel.java)
> > at com/ms/applet/AppletPanel.run (AppletPanel.java)
> > at java/lang/Thread.run (Thread.java)

but above that i get this error:

com.ms.security.SecurityExceptionEx[GeoCanvas.]: java.io.IOException: bad path: C:\WIN\Desktop\geoapp\java\awt\geom\Line2D$Double.class

my geometry app uses Line2D.Double (part of the awt) but for some reason, the browser is looking for a class file for it when i run the applet off my desktop. i don't understand why it would look for that but not have a problem when i use Point2D.Double, or some other awt class...
