Help me

Hi all of u,
I have some problem, My project is developped with bridge driver we want to migrate that project into linux redhat, remote database server is there while running the project in linux with tomcat it shows some errors, so i want to use thin driver to connect directly to that remote database. while using thin driver in linux it gives error message

“package oracle.jdbc.driver not existed”

In linux we dont have oracle is there any alternative without installing oracle9i in linux?
