JDBC

Hi,

    I've installed PostgreSQL 7.02 RPM Version with it's JDBC package RPM, now i'm trying to run my java application
thatconnects to postgresql.   driver:   postgresql.Driver    and connection:   jdbc:postgresql:mydb 

    I got errors saying class not found.   i tried to check for the file postgresql.jar and finder.jar  ... i can't
findthem...  
    what i found from the rpm of jdbc is jdbc7.0-1.2.jar and jdbc7.0-1.1.jar and the previous version jdbc6.5-1.2.jar
andjdbc6.5-1.2.jar 

    What should i do? please help me. Thanks
