Container-Managed Sign-On

In container-managed sign-on, an application component does not have to pass any sign-on security information to the getConnection() method. The security information is supplied by the container, as shown in the following example.

// Business method in an application component
Context initctx = new InitialContext();
// Perform JNDI lookup to obtain a connection factory
javax.resource.cci.ConnectionFactory cxf =
// Invoke factory to obtain a connection. The security
// information is not passed in the getConnection method
javax.resource.cci.Connection cx = cxf.getConnection();
