我的远程 RMI 呼叫缺少什么？

Question

我错过了什么？ 我正在尝试从独立的 java 应用程序向部署在 Jboss 6.4 EAP 中的 server-app-ear 进行远程 RMI 调用。 （我用standalone-full.xml 启动Jboss）

在我的服务器中，我在启动期间得到了这个日志记录：

07:47:56,928 INFO  [org.jboss.as.server.deployment] (MSC service thread 1-2) JBAS015973: Starting subdeployment (runtime-name: "se.testcompany.testapplication-server-0.0.1-SNAPSHOT.jar")
07:47:57,156 INFO  [org.jboss.as.ejb3.deployment.processors.EjbJndiBindingsDeploymentUnitProcessor] (MSC service thread 1-6) JNDI bindings for session bean named JournalCrudFacadeBean in deployment unit subdeployment "se.testcompany.testapplication-server-0.0.1-SNAPSHOT.jar" of deployment "app-0.0.1-SNAPSHOT.ear" are as follows:

java:global/app-0.0.1-SNAPSHOT/se.testcompany.testapplication-server-0.0.1-SNAPSHOT/JournalCrudFacadeBean!se.testcompany.testapplication.rmi_interface.JournalCrudRemoteInterface
java:app/se.testcompany.testapplication-server-0.0.1-SNAPSHOT/JournalCrudFacadeBean!se.testcompany.testapplication.rmi_interface.JournalCrudRemoteInterface
java:module/JournalCrudFacadeBean!se.testcompany.testapplication.rmi_interface.JournalCrudRemoteInterface
java:global/app-0.0.1-SNAPSHOT/se.testcompany.testapplication-server-0.0.1-SNAPSHOT/JournalCrudFacadeBean
java:app/se.testcompany.testapplication-server-0.0.1-SNAPSHOT/JournalCrudFacadeBean
java:module/JournalCrudFacadeBean

在我看来，我应该能够使用这些“名称”之一（可能是“全局”）“查找”JournalCrudFacadeBean，对吧？我猜“app”在同一个应用程序中很有用，而“模块”在同一个模块中是有用的，对吧？所以 global 听起来更像它。

我还在服务器中添加了一个应用程序用户“testapplication”。

来自 JournalCrudFacadeBean 的 sn-p 看起来像：

@Stateless
public class JournalCrudFacadeBean implements JournalCrudRemoteInterface {

    public String create(Date date) throws RemoteException 
    {   
        String id = "A id"
        System.out.println( id );
        return id;
    }

界面中的 sn-p 如下所示：

public interface JournalCrudRemoteInterface extends Remote
{
    public String create(Date date) throws RemoteException;

在我的独立应用程序中，我拨打如下电话：

private String create() 
{
    String id = "Inget svar";
    try 
    {
        final Hashtable<String, String> jndiProperties = new Hashtable<String, String>();

        
        jndiProperties.put(Context.INITIAL_CONTEXT_FACTORY, "org.jboss.naming.remote.client.InitialContextFactory");
        //jndiProperties.put(Context.INITIAL_CONTEXT_FACTORY, "org.wildfly.naming.client.WildFlyInitialContextFactory");

        jndiProperties.put(Context.URL_PKG_PREFIXES, "org.jboss.ejb.client.naming");
        jndiProperties.put(Context.PROVIDER_URL, "remoting://localhost:4447");
        
        jndiProperties.put("remote.connection.default.username", "testapplication");
        jndiProperties.put("remote.connection.default.password", "!234qwer");
        
                    
        final InitialContext ctx = new InitialContext( jndiProperties );

        JournalCrudRemoteInterface journalCrudRemoteInterface = (JournalCrudRemoteInterface) ctx.lookup( "java:global/app-0.0.1-SNAPSHOT/se.testcompany.testapplication-server-0.0.1-SNAPSHOT/JournalCrudFacadeBean!se.testcompany.testapplication.rmi_interface.JournalCrudRemoteInterface" );
        //JournalCrudRemoteInterface journalCrudRemoteInterface = (JournalCrudRemoteInterface) ctx.lookup( "java:global/app-0.0.1-SNAPSHOT/se.testcompany.testapplication-server-0.0.1-SNAPSHOT/JournalCrudFacadeBean" );
        id = journalCrudRemoteInterface.create(new Date());
        System.out.println(id);
    } 
    catch (Exception e) 
    {
        id = e.getClass().getName() + " " + e.getMessage();
        e.printStackTrace();
        
    } 
    finally 
    {
    }

    return id;
}

在客户端我得到了这些依赖：

[INFO] --- maven-dependency-plugin:2.8:tree (default-cli) @ rmi-client ---
[INFO] se.testcompany.testapplication:rmi-client:jar:0.0.1-SNAPSHOT

[INFO] \- se.testcompany.testapplication:rmi-interface:jar:0.0.1-SNAPSHOT:compile

但是当我调用它时，我得到：

INFO: JBoss Remoting version 5.0.0.Final
javax.naming.NameNotFoundException: global -- service jboss.naming.context.java.jboss.exported.global
    at org.jboss.as.naming.ServiceBasedNamingStore.lookup(ServiceBasedNamingStore.java:104)
    at org.jboss.as.naming.NamingContext.lookup(NamingContext.java:197)

各位，你们觉得我哪里做错了吗？ 最好的祝福 弗雷德里克

检查您的查找名称是否正确。您可以从 Jboss 的管理控制台 -> 运行时选项卡 -> JNDI 视图中检查它。您的查找是否有 JNDI
