Class OraConnectionFactory

java.lang.Object
oracle.dmt.jdm.resource.OraConnectionFactory

All Implemented Interfaces:

javax.datamining.resource.ConnectionFactory, javax.datamining.Factory, javax.naming.Referenceable, java.io.Serializable

public class OraConnectionFactory

extends java.lang.Object

implements javax.datamining.resource.ConnectionFactory, java.io.Serializable, javax.naming.Referenceable

OraConnectionFactory is an oracle extension of javax.datamining.resource.ConnectionFactory. ConnectionFactory can either be instantiated using OraConnectionFactory constructor or can be registered in JNDI server to access the connection instance in a vendor neutral architecture.
Following code illustrates these two approaches to create a connection factory.

//Case-1: Using OraConnectionFactory constructor.
javax.datamining.resource.ConnectionFactory connFactory =
oracle.dmt.jdm.resource.OraConnectionFactory();
ConnectionSpec cSpec = connFactory.getConnectionSpec();
cSpec.setURI("jdbc:oracle:thin:@host:port:sid");
cSpec.setName("dmuser");
cSpec.setPassword("dmuser");
connFactory.setConnectionSpec(cSpec);


//Case-2: Using JNDI
// Setup the initial context to connect to the JNDI server
Hashtable env = new Hashtable();
env.put( Context.INITIAL_CONTEXT_FACTORY,
"oracle.dmt.jdm.resource.OraConnectionFactory" );
env.put( Context.PROVIDER_URL, "http://myHost:myPort/myService" );
env.put( Context.SECURITY_PRINCIPAL, "user" );
env.put( Context.SECURITY_CREDENTIALS, "password" );
InitialContext jndiContext = new javax.naming.InitialContext( env );
// Perform JNDI lookup to obtain the connection factory
javax.datamining.resource.ConnectionFactory dmeConnFactory =
(ConnectionFactory) jndiContext.lookup("java:comp/env/jdm/MyServer");
//Lookup ConnectionFactory
javax.datamining.resource.ConnectionFactory connFactory =
(ConnectionFactory) jndiContext.lookup("java:comp/env/jdm/MyServer");
