Database Coonection in JDeveloper

Question

Hello,
I'm working with Jdeveloper 10.1.3 ADF Faces.
In my ADF Faces backing bean class I read text File and i must insert it to Oracle DB
Table:
How to use existing connection (for example HRConn) which is already defined in Connections Tab in Jdeveloper?
or I must create a new JDBC Connection in backing bean class like:
Connection conn = null;
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
conn = DriverManager.getConnection("jdbc:oracle:thin:@db:1521:Oracle", "hr", "hr");
Could you please give some small example.
Thank You in advance.

Whenever you create a DB connection in JDeveloper, it creates a set of DataSources for that connection. You can see them from Tools->Embedded OC4J settings dialog. In this dialog expand the 'Current Workspace -> Data Sources' tree.
The datasources are typically named as 'jdev-connection-managed-XXX' and 'jdev-connection-native-XXX' where XXX is the name of the DB connection e.g. HRConn.
You should be able to refer to these datasources using they jndi names listed in Embedded OC4J settings dialog mentioned above. Somethign like...
Context ctx = new InitialContext();
DataSource ds = (DataSource)ctx.lookup("jdbc/HRConnDS");
Connection conn = ds.getConnection();
Please note that this will run ONLY when you are running a page in the OC4J(embeded or properly setup oracle app server). This code will not run when you run it as part of a standalone java class.
