applet

[marco <th...@iol.it>]

Hi all,

this is my question:


I have tried a simple applet with a JSVGCanvas.
With the appletviewer I haven't had any problems, but with
the browser (Mozilla + plugin jre 131 on windows2k) I got this exception:

java.lang.ExceptionInInitializerError:
 java.security.AccessControlException:
 access denied (java.util.PropertyPermission
org.apache.batik.min_repaint_time read)



Any Ideas? (I can't sign the applet :-( )

Thank you,

Marco.

Hi Marco,

   Try using current CVS, this bug should be fixed there.
