Question

美好的一天，我在理解从独立的远程Java客户端成功调用位于集群中的EJB所需的内容（包括服务器配置）时遇到问题。到目前为止，我已经尝试了jboss的两个官方指南，到目前为止我的解决方案只能部分工作。

https://docs.jboss.org/author/display/WFLY9/WildFly+9+Cluster+Howto https://docs.jboss.org/author/display/WFLY9/EJB+invocations+from+a+remote+client+using+JNDI

目前在客户端，我正在使用“client bom”maven依赖：

    <dependency>
        <groupId>org.wildfly</groupId>
        <artifactId>wildfly-ejb-client-bom</artifactId>
        <version>10.0.0.Final</version>
        <type>pom</type>
    </dependency>

JNDI查找的初始上下文填充了下一个数据：

    Properties env = new Properties();

    env.put(Context.PROVIDER_URL, "http-remoting://somehost:8080");
    env.put(Context.SECURITY_PRINCIPAL, "client");
    env.put(Context.SECURITY_CREDENTIALS, "clientPassword");
    env.put(Context.INITIAL_CONTEXT_FACTORY, "org.jboss.naming.remote.client.InitialContextFactory");
    env.put("jboss.naming.client.ejb.context", true);

所有EJB都标有@ Stateless，@ Cluster和@Remote注释。如果我使用上面的配置与一个公共部署（不是一个集群），一切正常，并按照预期。但是，如果我尝试连接到我的一个集群实例，我将获得下一个响应（其中“backend2”是集群中的两个实例之一）：
