These are links to data source topics.
Sun Datasource has been extended by Oracle as OracleDataSource();
The library to include in your project in Jdeveloper is named Oracle JDBC.
You can provide database credentials to a datasource or use JNDI (Lookup). The avantage of using JNDI is that no credentials are hardcoded.
