here first you must create connector class using sql package(java.sql.DriverManager,java.sql.connection ,java.sql.Resultset,java.sqlyou uSqlException) these fileds are very important.then you must add mysql-connector-java-5.0.4-bin Executable jar file to your project's libraries.
find from the internet about connector class for java database.

Thanks..
