无法连接到 jboss 服务器 - 操作失败，状态为 WAITING

Question

尝试连接本地 jboss 服务器时出现此异常 (wildfly-8.2.0.Final)

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 还说它无法连接到端口 4447 的服务器。我在防火墙中打开了此端口，但没有帮助。

不要使用“remote://localhost:4447”，而是使用“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");

如果你使用的是 maven，别忘了添加这个依赖：

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

对于 JMS，您还需要这些：

  <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项。

WildFly 默认使用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);
