我已經成功開發了使用Oracle Glass-fish服務器4.1版本的JMS隊列,然後我可以使用java EE應用程序成功發送和讀取消息,但是我需要將發送者代碼實現爲Swing應用程序,我使用了相同的代碼,Java EE應用程序,但它不做工精細,請參考下面的代碼使用java Swing發送消息給JMS隊列
public class SenderSwing {
/**
* @param args the command line arguments
*/
public static void main(String[] args) {
try {
new SenderSwing().sendJMSMessageToDefaultQueue("Hi "+System.currentTimeMillis());
}catch(Exception e){
e.printStackTrace();
}
}
private void sendJMSMessageToDefaultQueue(Object messageData) throws JMSException, NamingException {
Context c = new InitialContext();
ConnectionFactory cf = (ConnectionFactory) c.lookup("java:comp/DefaultJMSConnectionFactory");
Connection conn = null;
Session s = null;
try {
conn = cf.createConnection();
s = conn.createSession(false, s.AUTO_ACKNOWLEDGE);
Destination destination = (Destination) c.lookup("jms/defaultQueue");
MessageProducer mp = s.createProducer(destination);
mp.send(createJMSMessageForjmsDefaultQueue(s, messageData));
} finally {
if (s != null) {
try {
s.close();
} catch (JMSException e) {
Logger.getLogger(this.getClass().getName()).log(Level.WARNING, "Cannot close session", e);
}
}
if (conn != null) {
conn.close();
}
}
}
private Message createJMSMessageForjmsDefaultQueue(Session session, Object messageData) throws JMSException {
// TODO create and populate message to send
TextMessage tm = session.createTextMessage();
tm.setText(messageData.toString());
return tm;
}
}
上面的代碼給我象下面這樣的例外,
javax.naming.NoInitialContextException: Need to specify class name in environment or system property, or as an applet parameter, or in an application resource file: java.naming.factory.initial
at javax.naming.spi.NamingManager.getInitialContext(NamingManager.java:662)
at javax.naming.InitialContext.getDefaultInitCtx(InitialContext.java:313)

at senderswing.SenderSwing.sendJMSMessageToDefaultQueue(SenderSwing.java:43)
at senderswing.SenderSwing.main(SenderSwing.java:35)
任何人都可以幫忙。
