Grails with Firebird: ClassNotFoundException

[alexey]

Hi all, I'm new in grails and i have a problem. I modified DataSource.groovy file for Firebird database:

development {
        dataSource {
            dbCreate = "create" // one of 'create', 'create-drop', 'update', 'validate', ''
            url = "jdbc:firebirdsql:10.0.2.15/3050:C:/mfc_helper.fdb?lc_ctype=UTF-8"
            driverClassName = "org.firebirdsql.jdbc.FBDriver"
            username = "sysdba"
            password = "masterkey"
            dialect = "org.hibernate.dialect.FirebirdDialect"
        }
    }

but, during 'run-app' command i get an error:

Caused by ClassNotFoundException: org.firebirdsql.jdbc.FBDriver

Can anyone help me?
