Same problem, but security solution

Posted by Rogier on October 22, 2001 at 9:45 AM

Create policy file (YourfilePol)by copying this into a ascii text file:
grant {
permission java.lang.RuntimePermission
"accessClassInPackage.sun.jdbc.odbc";
permission java.util.PropertyPermission
"file.encoding", "read";
};

Then put this in the htm-file:
appletviewer -J-Djava.security.policy=YourfilePol Yourfile.htm
To get rid of the security error.
Whatever I do, I can't get rid of the java.lang.InstantiationException error.

> but above that i get this error:

> 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...
