I follow your advice (unzip the package  (classes111.zip - Yes! With the
classes12.zip don´t run) and include  in my package) and run my application.

But, after many seconds, I receive this error  message:
java.sql.SQLException: Io exception: The Network Adapter could not
establish the connection

Do you know this error?

We have two environment
W2000 - development
Linux - test
In the W2000 I get run my application  and access  the Oracle server without
any problem with the driver file  classes12.zip
In the Linux I try use the classes12, but don´t run, only run with the
classes111. Why this?
