Hey, hey,
That's our famous one.
This is due to the fact the 1.0 distribution of XML-RPC uses the
sun.misc Base64 encoder/decoder classes so as to encode/decode binary
parts of XML-RPC messages in the applet package.
This exception has been noticed, by us at least, as SecurityException,
using appletviewer and all non-internet-explorer related applet engines
on MacOSX and Linux.
The workaround ? Use the base64 encoding classes that are under LGPL in
the org.apache.xmlrpc package (not the applet one).
I have made this fix, together with a few others and have suggested
these to the mailing list about a week ago. It is published (under the
same licenses) at:
http://www.activemath.org/~ilo/revisions/xmlrpc/
Using this should fix your problem.
(we're using the applet parameters for port number and other such as
applet-params, i.e. not an absolute or computed URL which makes sure
that the host is the same and it works fine with us)
Tell me (the list I guess) of any problem you encounter as we cannot
eternally debug on all flavours of browsers/platforms combinations.
