/**
*  The AS400JDBCObjectFactory is used by a JNDI service provider to reconstruct an object
*  when it is retrieved from JNDI.
*
*  When constructing your own Reference object, at a minimum, you should set the serverName,
*  userName, pwd, and secure properties.  
*  
*  
For Example:        
*  
*  XADataSource xads = null; 
*  String objFactoryName = "com.ibm.as400.access.AS400JDBCObjectFactory";
*  String xadsName = "com.ibm.as400.access.AS400JDBCXADataSource";
*  Reference ref = new Reference(xadsName, objFactoryName, "");
*  ref.add(new StringRefAddr("serverName", "someserver"));
*  ref.add(new StringRefAddr("userName", "someuser"));
*  ref.add(new StringRefAddr("pwd", "somepassword"));
*  ref.add(new StringRefAddr("secure", "false"));
*  ref.add(new StringRefAddr("trace", "true"));
*  try {
*      ObjectFactory objectFactory = (ObjectFactory)Class.forName(objFactoryName).newInstance();
*      xads = (XADataSource)objectFactory.getObjectInstance(ref, null, null, null);
*      XAConnection xacon = xads.getXAConnection();
*      Connection con = xacon.getConnection();
*  } catch (Exception ex) {
*      ex.printStackTrace();
*      System.err.println("Exception caught: " + ex);
*  }
*  
*  The following classes implement the javax.naming.Referenceable interface.
*  @see com.ibm.as400.access.AS400JDBCDataSource
*  @see com.ibm.as400.access.AS400JDBCConnectionPoolDataSource
