Cannot find ConnectionFactory with JNDI on JMS
提问by javaLovah
I'm new to JMS , and I'm trying to load a connectionFactory. I followed a couple of tutorials , but for some reason it doesn't seem to work , I get an exception every time I try to '.lookup' connectionfactory. I'm using JBoss7.1.
我是 JMS 新手，我正在尝试加载 connectionFactory。我遵循了几个教程，但由于某种原因它似乎不起作用，每次尝试“.lookup”连接工厂时都会出现异常。我正在使用 JBoss7.1。
Here is the class from where I'm trying to get the connectionFactory:
这是我试图从中获取 connectionFactory 的类：
public class QueueSend extends Frame implements ActionListener {
private QueueConnectionFactory qconFactory;
private QueueConnection qcon;
private QueueSession qsession;
private QueueSender qsender;
private Queue queue;
private TextMessage msg;
private TextField tf=new TextField();
private Button send=new Button("Send");
public QueueSend(){
super("Queue Sender");
setLocation(150,50);
setSize(200,100);
add(tf);
add(send,BorderLayout.SOUTH);
send.addActionListener(this);
send.setEnabled(false);
addWindowListener(new WindowAdapter(){
public void windowClosing(WindowEvent w){
send("quit");
close();
System.exit(0);
}
});
setVisible(true);
init();
}
public void init(){
try{
InitialContext ctx = getInitialContext();
qconFactory = (QueueConnectionFactory) ctx.lookup("ConnectionFactory");
queue = (Queue) ctx.lookup("java:/queue/text");
qcon = qconFactory.createQueueConnection();
qsession = qcon.createQueueSession(false, Session.AUTO_ACKNOWLEDGE);
qsender = qsession.createSender(queue);
qcon.start();
send.setEnabled(true);
}catch(NamingException e1){e1.printStackTrace();
}catch(JMSException e2){e2.printStackTrace();}
}
public void actionPerformed(ActionEvent e){
String message=tf.getText();
tf.setText("");
if(message.length()>0)
send(message);
}
public void send(String message){
try{
//send a message with the given string
TextMessage textMessage = qsession.createTextMessage(message);
qsender.send(textMessage);
// enter text here
}catch(JMSException e){e.printStackTrace();}
}
public void close(){
try{
qsender.close();
qsession.close();
qcon.close();
}catch(JMSException e1){e1.printStackTrace();
}catch(NullPointerException e2){e2.printStackTrace();}
}
public static void main(String[] args){
new QueueSend();
}
public InitialContext getInitialContext(){
Properties properties = new Properties();
properties.put(Context.URL_PKG_PREFIXES,"org.jboss.ejb.client.naming");
properties.put(Context.INITIAL_CONTEXT_FACTORY, "org.jboss.naming.remote.client.InitialContextFactory");
properties.put("jboss.naming.client.connect.options.org.xnio.Options.SASL_POLICY_NOPLAINTEXT", "false");
properties.put("java.naming.provider.url","remote://127.0.0.1:4447");
properties.put("jboss.naming.client.ejb.context","true");
properties.put("jboss.naming.client.connect.options.org.xnio.Options.SASL_POLICY_NOPLAINTEXT","false" );
try {
return new InitialContext(properties);
} catch (NamingException e) {
System.out.println("Cannot generate InitialContext");
e.printStackTrace();
}
return null;
}
}
I get this exception:
我得到这个例外：
javax.naming.NameNotFoundException: ConnectionFactory -- service jboss.naming.context.java.jboss.exported.ConnectionFactory

When i log into JBoss server from the browser , I can't find 'ConnectionFactory' under the 'naming' tab
当我从浏览器登录 JBoss 服务器时，在“命名”选项卡下找不到“ConnectionFactory”
this is from the standalone-full.xml:
这是来自standalone-full.xml：
<jms-connection-factories>
<connection-factory name="InVmConnectionFactory">
<connectors>
<connector-ref connector-name="in-vm"/>
</connectors>
<entries>
<entry name="java:/ConnectionFactory"/>
</entries>
</connection-factory>
<connection-factory name="RemoteConnectionFactory">
<connectors>
<connector-ref connector-name="netty"/>
</connectors>
<entries>
<entry name="RemoteConnectionFactory"/>
<entry name="java:jboss/exported/jms/RemoteConnectionFactory"/>
</entries>
</connection-factory>
<pooled-connection-factory name="hornetq-ra">
<transaction mode="xa"/>
<connectors>
<connector-ref connector-name="in-vm"/>
</connectors>
<entries>
<entry name="java:/JmsXA"/>
</entries>
</pooled-connection-factory>
</jms-connection-factories>
What am i doing wrong ?
我究竟做错了什么 ？

I found out what the problem was. The default configuration file for my JBoss server was standalone.xml while the connectionFactory is configured in the standalone-full.xml file which is a more full version of the standalone.xml, So all I had to do was change the configuration file of the server from standalone.xml to standalone-full.xml and that did the trick :@)~
我发现了问题所在。我的 JBoss 服务器的默认配置文件是 standalone.xml 而 connectionFactory 是在 standalone-full.xml 文件中配置的，这是一个更完整的 standalone.xml 版本，所以我所要做的就是更改服务器从standalone.xml 到standalone-full.xml 就成功了:@)~

For me, I was trying to look up java:jboss/exported/jms/RemoteConnectionFactoryin on the remote Widlfly. Instead of using java:/jms/RemoteConnectionFactorywhich was wrong, I needed to look up jms/RemoteConnectionFactory(the text after exported).
对我来说，我试图仰望java:jboss/exported/jms/RemoteConnectionFactory遥远的 Widlfly。而不是使用java:/jms/RemoteConnectionFactorywhich 是错误的，我需要查找jms/RemoteConnectionFactory（后面的文本exported）。
