Question

我使用的是Jboss EAP 6.3，需要使用Messaging工具。我曾在Jboss 4x工作，我们可以使用以下代码轻松建立连接：

public static final String PROVIDER_URL = "jnp://localhost:5445";
   public static final String JNP_INTERFACES = "org.jboss.naming:org.jnp.interfaces";
   public static final String INITIAL_CONTEXT_FACTORY = "org.jnp.interfaces.NamingContextFactory";

   private static Context initialContext;

   public static Context getInitialContextForClient() throws NamingException{
          if(initialContext == null){
                 Properties prop = new Properties();
                 prop.put(Context.INITIAL_CONTEXT_FACTORY, INITIAL_CONTEXT_FACTORY);
                 prop.put(Context.URL_PKG_PREFIXES,JNP_INTERFACES);
                 prop.put(Context.PROVIDER_URL, PROVIDER_URL);
                 initialContext = new InitialContext(prop);
          }
          return initialContext;
   }

以上方式是否可以在EAP 6.3中连接到HornetQ？如果是，还需要哪些其他配置？另外，我发现在standalone.xml中默认情况下也没有配置1099。

以下是在Standalone-full.xml文件中为HornetQ执行的默认设置：

<subsystem xmlns="urn:jboss:domain:messaging:1.4">
        <hornetq-server>

            </connectors>

            <acceptors>

            <jms-destinations>

                <jms-queue name="DLQ">
                    <entry name="java:/jms/queue/DLQ"/>
                </jms-queue>
            </jms-destinations>
        </hornetq-server>
    </subsystem>

以下是同一文件中的套接字绑定：

<socket-binding name="messaging" port="5445"/>
    <socket-binding name="messaging-group" port="0" multicast-address="${jboss.messaging.group.address:231.7.7.7}" multicast-port="${jboss.messaging.group.port:9876}"/>
    <socket-binding name="messaging-throughput" port="5455"/>

我在下面尝试过，因为无法在Jboss EAP 6.3中看到org.jnp.interfaces.NamingContextFactory类：

prop.put(Context.PROVIDER_URL,"localhost:5445"); 
prop.put(Context.INITIAL_CONTEXT_FACTORY,"org.hornetq.core.remoting.impl.netty.NettyConnectorFactory");
prop.put(Context.URL_PKG_PREFIXES,"org.jboss.naming:org.jnp.interfaces");

目前，它正在抛出连接异常。

有人可以建议或提交一个关于如何在Jboss EAP 6.3中实现与Hornetq连接的java程序吗？

更新：我仍然不知道我是否遵循了做同样的正确程序。

以下是我得到的例外情况：

javax.naming.NamingException: JBAS011843: Failed instantiate InitialContextFactory org.jnp.interfaces.NamingContextFactory from classloader ModuleClassLoader for Module

我在bin / client中检查了它的jboss-client.jar，发现上面的接口不存在，但是在以前的版本中包含jbiss-allclient.jar。我不认为把它放在这个jboss版本中是正确的。

根据您的堆栈跟踪，我假设您没有将旧的JNDI设置擅长JBoss EAP 6.3

来自：http://blog.akquinet.de/2014/09/26/jboss-eap-wildfly-three-ways-to-invoke-remote-ejbs/

Properties prop = new Properties();

prop.put(Context.INITIAL_CONTEXT_FACTORY, "org.jboss.naming.remote.client.InitialContextFactory");

prop.put(Context.PROVIDER_URL, "http-remoting://127.0.0.1:8080");
prop.put(Context.SECURITY_PRINCIPAL, "username");
prop.put(Context.SECURITY_CREDENTIALS, "password");

prop.put("jboss.naming.client.ejb.context", false);
prop.put(Context.URL_PKG_PREFIXES, "org.jboss.ejb.client.naming");

Context context = new InitialContext(prop);

您的应用程序无法实例化initialContext，这是您应该关注的问题。

另外，对我来说，消息队列和你的jndi都试图连接localhost：5445看起来有点奇怪。

点击this jboss链接;其中包含解决上述问题的快速启动程序。

1）下载代码;在netbeans中导入run jboss-helloworld-jms的pom.xml。运行干净的构建。

2）使用此链接解决maven构建问题： Pom not found

3）以下是用于连接服务器的片段

private static final String DEFAULT_MESSAGE = "Hello, World!";
private static final String DEFAULT_CONNECTION_FACTORY = "jms/RemoteConnectionFactory";
private static final String DEFAULT_DESTINATION = "jms/queue/test";
private static final String DEFAULT_MESSAGE_COUNT = "1";
private static final String DEFAULT_USERNAME = "quickstartUser";
private static final String DEFAULT_PASSWORD = "quickstartPwd1!";
private static final String INITIAL_CONTEXT_FACTORY = "org.jboss.naming.remote.client.InitialContextFactory";
private static final String PROVIDER_URL = "remote://localhost:4447";

String connectionFactoryString = System.getProperty("connection.factory", DEFAULT_CONNECTION_FACTORY);
log.info("Attempting to acquire connection factory \"" + connectionFactoryString + "\"");
connectionFactory = (ConnectionFactory) context.lookup(connectionFactoryString);
log.info("Found connection factory \"" + connectionFactoryString + "\" in JNDI");

4）在Jboss EAP 6.3中创建用户＆＃34; quickstartUser＆＃34; /＆＃34; quickstartPwd1！＆＃34;，在应用领域中使用adduser.bat

5）检查Standalone.xml中是否存在这些jms / queue / test和jms / RemoteConnectionFactory。

6）运行代码作为简单的Java应用程序，魔术就在那里。

编写Java程序以连接到Jboss EAP 6.3中的HornetQ Messaging Service？
