Hi Vicky,

Thank you very much for your help,

No, I declare all the properties in -ds.xml file e.g. and JBoss will read those. I prefer this way to hard coding properties into the codes. Below is the content of my -ds.xml

sampleds.xml

<connection-factories>
  |     <no-tx-connection-factory>
  |         <jndi-name>SimplewireDS</jndi-name>	
  |         <rar-name>65-mitto-ra-smpp.rar</rar-name>
  |         <connection-definition>
  |              com.smsc.mitto.ra.smpp.SMPPConnectionFactory
  |         </connection-definition>
  | 	<config-property name="Name" type="java.lang.String">Mitto-1</config-property>
  |         <config-property name="Server" type="java.lang.String">192.168.2.115</config-property>
  |         <config-property name="Port" type="java.lang.Integer">9999</config-property>
  | 	<config-property name="Username" type="java.lang.String">binh</config-property>
  | 	<config-property name="Password" type="java.lang.String">binh</config-property>
  |         <min-pool-size>0</min-pool-size>
  |         <max-pool-size>4</max-pool-size>
  | 	<idle-timeout-minutes>525600</idle-timeout-minutes> <!-- if idle for a year reconnect... -->
  | 	<blocking-timeout-millis>100</blocking-timeout-millis>
  | 	<prefill>true</prefill>
  |     </no-tx-connection-factory>
  | </connection-factories>

The properties are loaded in my <managed-connection-factory> class

public Object createConnectionFactory(ConnectionManager connectionManager)
  | 	    throws ResourceException {
  | 	logger
  | 		.info("Creating connection factory (with specified connectionmanager) in TelnetManagedConnectionfactory with id="
  | 			+ id);
  | 
  | 	// At this stage the values from the configuration file should have been
  | 	// set
  | 	if (server != null && port != 0 && username != null && password != null
  | 		&& name != null) {
  | 	    SMPPRequestInfo smppInfo;
  | 
  | 	    smppInfo = new SMPPRequestInfo(username, password, server, port,
  | 		    name);
  | 	    return new SMPPConnectionFactoryImpl(connectionManager, this,
  | 		    smppInfo);
  | 	} else
  | 	    throw new ResourceException();
  |     }
  | 
  |     public void setUsername(String username) {
  | 	this.username = username;
  |     }
  | 
  |     public void setPassword(String password) {
  | 	this.password = password;
  |     }
  | 
  |     public void setServer(String server) {
  | 	this.server = server;
  |     }
  | 
  |     public void setPort(Integer port) {
  | 	this.port = port;
  |     }
  | 
  |     public void setName(String name) {	
  | 	this.name = name;
  |     }

  | Look at the jdbc resource adapter implemetaion of the connectionfactory-impl-class here 
  | 
  | Since I declare all the properties in -ds.xml, I would probably not need to pass the ConnectionRequestInfo in my <connection-factory-impl> class. Here is the codes:

  |     public SMPPConnection getConnection() throws NamingException {
  | 	logger
  | 		.info("Request an SMPPConnection from the SMPPConnectionFactoryImpl with id="
  | 			+ id);
  | 	SMPPConnectionImpl tc = null;
  | 	try {	    
  | 	    tc = (SMPPConnectionImpl) manager.allocateConnection(factory,
  | 		    smppInfo);
  | 	    return tc;
  | 	} catch (ResourceException ex) {
  | 	// doing something    
  | 	}
  |     }
