JMSException: hosts (hostname:port) cannot be accessed

[Former Member]

Hi,

I am trying to write a simple Java Standalone application that talks to a MessageDrivenBean sitting inside my J2EE application in SAP WAS. I have done all that is required in terms of the right descriptors, deploying my application ear etc.

<b>This is the code in my Standalone client;</b>

Properties m_JNDIProperties = new Properties();
 m_JNDIProperties.put(Context.INITIAL_CONTEXT_FACTORY,"com.sap.engine.services.jndi.InitialContextFactoryImpl");
            
 m_JNDIProperties.put (Context.PROVIDER_URL,"localhost:50004");
 m_JNDIProperties.put(Context.SECURITY_PRINCIPAL,"Administrator");
 m_JNDIProperties.put(Context.SECURITY_CREDENTIALS,"*****");
			
 /*    Create a JNDI API InitialContext object.    */
 m_Context = new InitialContext(m_JNDIProperties);	
		           
 queueConnectionFactory = (QueueConnectionFactory) m_Context.lookup("jmsfactory/default/QueueConnectionFactory");
queueConnection = queueConnectionFactory.createQueueConnection();

Everything works fine but the last line of code which throws the following exception:

javax.jms.JMSException: The following hosts (hostname:port) cannot be accessed: . Check host names and ports.
	at com.sap.jms.client.connection.ConnectionFactory.getSocket(ConnectionFactory.java:447)
	at com.sap.jms.client.connection.ConnectionFactory.createConnection(ConnectionFactory.java:300)
	at com.sap.jms.client.connection.ConnectionFactory.createConnection(ConnectionFactory.java:244)
	at com.sap.jms.client.connection.QueueConnectionFactory.createQueueConnection(QueueConnectionFactory.java:70)

	at com.yambay.mach.gatewayjmsbridge.JMSTestClient.main(JMSTestClient.java:75)

I have spent 5 hrs now trying different stuff but for the love of god just can;t get past that last line.

I would greatly appreciate any sugestions that might fix this problem.

Thanks
