2.3. Define a Connection Factory

Extend the org.teiid.resourse.spi.BasicConnectionFactory class, and provide an implementation for the getConnection() method. This method will create and return an instance of a connection. 
public class MyConnectionFactory extends BasicConnectionFactory 
{
   @Override
   public MyConnection getConnection() throws ResourceException 
   {
      return new MyConnection();
   }  
}
Since the Managed Connection Factory creates a Connection Factory, it has access to all the configuration parameters so that the getConnection() method can pass credentials to the requesting application. Therefore, the Connection Factory can reference the calling user's javax.security.auth.Subject from within the getConnection() method. 
Subject subject = ConnectionContext.getSubject();
A Subject can give access to logged-in user's credentials and roles that are defined. This may be null.

Note

You can define a security-domain for this resource adapter that is separate from the default Red Hat JBoss Data Virtualization security-domain for validating the JDBC user. However, it is the user's responsibility to perform the necessary logins before the application server's thread accesses this resource adapter.
