Re: [Jython-users] I don't get this..: Newbie

[Rune H. <ro...@vi...>]

Regarding my previous post. I found and applyed the fix for the "Py Meta
Class Bug". Lo and behold the applet runs.
Now I get an error then exceuting the pageHandler function:
"LookupError: no codec search functions registered: can't find encoding"

Am I far off the mark when I suggest that jython2.x isn't quite ready for
this kind of applets yet? I haven't had any problems with applets that
don't use "Cpython" modules.

regards
