I guess this is the problem: your applet does not have permissions to connect
to host 10.0.0.5. You should grant such permission to your applet (quick
thought).

I'm understand this, but my applet signed!
Or I must change policy file on my computer(I have an applet)...

how to give this permission to my applet?

sorry my bad english))

Decision: need move the class files of the driver into applet jar file and sign all.

Thanx, Luca
