connector/j installed properly doesnt work!

[Adriano Esposito]

Hi to all, and soon I want to apologize for my english..

the fact is, I have an application usign connector/j. I must continue the developing of this sw on a machine with MSW2kSP3, MySQL 4.1.110 and Eclipse 3.0.1. I installed properly all but the Connector/J,
although I copied the jar into the /lib/ext of my java home it doesnt work.
My connession with forName method and com.mysql.jdbc.Driver argument does not see the class.
I dont know what I mistake..

This the error:

java.lang.ClassNotFoundException: com.mysql.jdbc.Driver

(oracle is an old indication, the sw work on mysql)

Any suggestions will be appreciated..
