Translet Extension Error

[Xserty <xs...@libero.it>]

Hi!
         I'm new to Xalan, and I'm trying to compile a stylesheet with a 
Java extension.
This stylesheet with Java extension works fine if I transform it using the 
TrAX.
If I try to compile it as a Translet, I get the following error message 
from the getErrors()
vector:
Cannot find external method 'myToString' (must be public).
(It is public and it's in my CLASSPATH)

I've searched through the mailling list archives, but I didn't find an answer!

Hope to hear from you and thanks in advance! ;))
