我不明白什么不好，我需要有关此代码的帮助，所以这是代码
package chat;
import javax.jms.*;
import javax.naming.*;
import java.io.*;
import java.io.InputStreamReader;
import java.util.Properties;
public class pub implements javax.jms.MessageListener{
private TopicSession pubSession;
private TopicSession subSession;
private TopicPublisher publisher;
private TopicConnection connection;
private String username;
/* Constructor. Establish JMS publisher and subscriber */
public pub(String topicName, String username, String password)
throws Exception {
// Obtain a JNDI connection
Properties env = new Properties( );
env.put(Context.SECURITY_PRINCIPAL, "guest");
env.setProperty("java.naming.factory.initial", "org.jnp.interfaces.NamingContextFactory");
env.setProperty("java.naming.provider.url", "localhost:1099");

// ... specify the JNDI properties specific to the vendor
InitialContext jndi = new InitialContext(env);
// Look up a JMS connection factory
TopicConnectionFactory conFactory =
(TopicConnectionFactory)jndi.lookup("TopicConnectionFactory");
// Create a JMS connection
TopicConnection connection =
conFactory.createTopicConnection(username,password);
// Create two JMS session objects
TopicSession pubSession =
connection.createTopicSession(false,
Session.AUTO_ACKNOWLEDGE);
TopicSession subSession =

Session.AUTO_ACKNOWLEDGE);
// Look up a JMS topic

// Create a JMS publisher and subscriber

pubSession.createPublisher(chatTopic);
TopicSubscriber subscriber =
subSession.createSubscriber(chatTopic);
// Set a JMS message listener
subscriber.setMessageListener(this);
// Intialize the Chat application
set(connection, pubSession, subSession, publisher1, username);
// Start the JMS connection; allows messages to be delivered
connection.start( );
}
/* Initialize the instance variables */
public void set(TopicConnection con, TopicSession pubSess,
TopicSession subSess, TopicPublisher pub,
String username) {
this.connection = con;
this.pubSession = pubSess;
this.subSession = subSess;
this.publisher = pub;
this.username = username;
}
/* Receive message from topic subscriber */
public void onMessage(Message message) {
try {
TextMessage textMessage = (TextMessage) message;
String text = textMessage.getText( );
System.out.println(text);
} catch (JMSException jmse){ jmse.printStackTrace( ); }
}
/* Create and send message using topic publisher */
protected void writeMessage(String text) throws JMSException {
TextMessage message = pubSession.createTextMessage( );
message.setText(username+" : "+text);
publisher.publish(message);
}
/* Close the JMS connection */
public void close( ) throws JMSException {
connection.close( );
}
/* Run the Chat client */
public static void main(String [] args){
try{
if (args.length!=3)
System.out.println("Topic or username missing");
// args[0]=topicName; args[1]=username; args[2]=password
pub chat = new pub("chat","temp","111");
// Read from command line
BufferedReader commandLine = new
java.io.BufferedReader(new InputStreamReader(System.in));
// Loop until the word "exit" is typed
while(true){
String s = commandLine.readLine( );
if (s.equalsIgnoreCase("exit")){
chat.close( ); // close down connection
System.exit(0);// exit program
} else
chat.writeMessage(s);
}
} catch (Exception e){ e.printStackTrace( ); }
}
}
这是我在 eclipce 中运行它时遇到的错误：

我不明白问题是来自 jboss 连接还是代码不正确，请我需要帮助来运行这个程序谢谢！！！！
