Paulo Cesar, o erro ocasionado é por que não existe esta classe org.apache.derby.jdbc.ClientDriver no class-path do seu projeto. No site http://db.apache.org/derby/derby_downloads.html voce pode baixar o Derby e o jar que vc necessitará para executar o seu projeto (ser vc baixar a versão http://db.apache.org/derby/releases/release-10.8.2.2.cgi o jar é o derbyclient.jar, adicione-o ao class-path do seu projeto).

Espero ter ajudado.

Att,
