First Glassfish JDBC connection pool

Trying to establish jdbc connection pool on fresh glassfish instalation.
Message from glassfish is:

Class name is wrong or classpath is not set for : com.mysql.jdbc.jdbc2.optional.MysqlDataSource

 
Why? Because it cannot find mysql-connector-java-5.x.xx-bin.jar
So find it and give him to the ~/domains/domain1/lib

Additional parameters you have to provide:
serverName:
databaseName:
User:
serverName:
Password:
