我在同一台机器上运行 jboss5 和 jboss 7，所以我更改了端口号（jboss5-4040 和 jboss7-8080）。我需要从 jboss 5 向 jboss 7 发送消息。我读了一篇文章，指出必须使用 JMS 桥接器。
https://community.jboss.org/wiki/BridgeJMSMessagesFromAS5ToAS7
我在 jboss 5 中创建了一个队列，并通过独立程序将消息发送到队列。
import java.io.Console;
import java.util.Properties;
import javax.jms.*;
import javax.naming.Context;
import javax.naming.InitialContext;
import javax.naming.NamingException;
public class sender {
String url_;
String name_;
Connection conn = null;
Session session = null;
Queue queue = null;
public sender(String url, String name) throws JMSException,
NamingException {
url_ = url;
name_ = name;
this.initializeSender();
}
private void initializeSender() throws JMSException, NamingException {
Properties props = new Properties();
props.setProperty("java.naming.factory.initial",
"org.jnp.interfaces.NamingContextFactory");
props.setProperty("java.naming.factory.url.pkgs", "org.jboss.naming");
props.setProperty("java.naming.provider.url", "jnp://localhost:1099");
Context context = new InitialContext(props);
ConnectionFactory cf = (ConnectionFactory) context
.lookup("java:/ConnectionFactory");
conn = cf.createConnection();
session = conn.createSession(false, Session.AUTO_ACKNOWLEDGE);
queue = (Queue) context.lookup(name_);
conn.start();
}
public void send(String text) throws JMSException, NamingException {
// Send a text msg
MessageProducer producer = session.createProducer(queue);
TextMessage tm = session.createTextMessage(text);
producer.send(tm);
producer.close();
}
public void disconnect() throws JMSException {
if (conn != null) {
conn.stop();
}
if (session != null) {
session.close();
}
if (conn != null) {
conn.close();
}
}
public String getTopicName() {
return name_;
}
public String getTopicURL() {
return url_;
}
public static void main(String args[]) throws Exception {
sender sender = new sender("remote://localhost:4447", "BalaQueue");
sender.send("My Message");
sender.disconnect();
}
}
我在 jboss 7 中创建了一个队列，并通过独立程序将消息发送到队列。

sender.send(message);
}
// Exit
reader.close();
System.out.println("Exiting...");
connection.close();
} catch (Exception e) {

System.exit(1);
