尝试连接到本地jboss服务器时遇到此异常（wildfly-8.2.0.Final）

    javax.naming.NamingException: Failed to create remoting connection [Root exception is java.lang.RuntimeException: Operation failed with status WAITING]

JNDI属性如下：

@BeforeClass
    public static void obtainProxyReferences() throws Throwable {

        Properties properties = new Properties();
        properties.put(Context.INITIAL_CONTEXT_FACTORY, "org.jboss.naming.remote.client.InitialContextFactory");
        properties.put(Context.PROVIDER_URL, "remote://localhost:4447");
        properties.put("jboss.naming.client.ejb.context", true);
        properties.put(Context.URL_PKG_PREFIXES, "org.jboss.ejb.client.naming");
        properties.put(Context.SECURITY_PRINCIPAL, "testuser");
        properties.put(Context.SECURITY_CREDENTIALS, "!Test1");
        namingContext = new InitialContext(properties);

        bean = (MeBeanImpl) namingContext.lookup(JNDI_NAME);
    }

Telnet还表示它无法通过端口4447连接到服务器。我在防火墙中打开了这个端口，但它没有帮助。

默认情况下，WildFly使用8080作为远程端口。 EJB客户端API使用具有http-upgrade功能的http端口与服务器进行通信以进行远程调用。

例如：

Properties jndiProps = new Properties();
jndiProps.put(Context.INITIAL_CONTEXT_FACTORY, "org.jboss.naming.remote.client.InitialContextFactory");
jndiProps.put(Context.PROVIDER_URL,"http-remoting://localhost:8080");
jndiProps.put("jboss.naming.client.ejb.context", true);
jndiProps.put(Context.SECURITY_PRINCIPAL, "testuser");
jndiProps.put(Context.SECURITY_CREDENTIALS, "!Test1");

// create a context passing these properties
Context ctx = new InitialContext(jndiProps);
// lookup
ctx.lookup(JNDI_NAME);

如果您正在使用maven，请不要忘记添加此依赖项：

  <dependency>
    <groupId>org.wildfly</groupId>
    <artifactId>wildfly-ejb-client-bom</artifactId>
    <version>8.0.0.Final</version>
    <type>pom</type>
  </dependency>

对于JMS，您也需要这些：

  <dependency>
    <groupId>org.hornetq</groupId>
    <artifactId>hornetq-jms-client</artifactId>
    <version>2.2.13.Final</version>
  </dependency>
  <dependency>
    <groupId>org.hornetq</groupId>
    <artifactId>hornetq-core-client</artifactId>
    <version>2.2.13.Final</version>
  </dependency>

这应该是您需要的唯一依赖。

Answer 3

而不是使用“remote：// localhost：4447”使用“http-remoting：// localhost：8080”

properties.put(Context.PROVIDER_URL, "http-remoting://localhost:8080");

在代码中配置jndi属性时，查找名称不应包含ejb:

JNDI_NAME = "ear-name/ejb-name/beanClass!beanInterface.fullpath");

Answer 4

更改您的财产

properties.put（Context.PROVIDER_URL，＆＃34; remote：// localhost：4447＆＃34;）;

到

properties.put（Context.PROVIDER_URL，＆＃34; http-remoting：// localhost：4447＆＃34;）;

无法连接到jboss服务器 - 操作失败，状态为WAITING
