Question

远程客户端的奇怪行为。当我调用ejb facade方法计数时，它是工作并返回用户数。但是当我通过物体时，却失败了！有错误

EJBCLIENT000025：没有可用于处理[appName：writer-ear，moduleName：writer-ejb-1.0，distinctName：]组合的EJB接收器，用于调用上下文org.jboss.ejb.client.EJBClientInvocationContext@331e965f

我配置了所有可能的方法，但仍然远程客户端失败。

例如

/////////////////////////////
        // The "standard" JNDI lookup
        final Hashtable jndiProperties = new Hashtable();
        jndiProperties.put(Context.INITIAL_CONTEXT_FACTORY, "org.jboss.naming.remote.client.InitialContextFactory");
        //jndiProperties.put("jboss.naming.client.connect.options.org.xnio.Options.SASL_POLICY_NOPLAINTEXT", "false"); // needed for a login module that requires the password in plaintext
        jndiProperties.put(Context.PROVIDER_URL, "http-remoting://127.0.0.1:8080");
        //  jndiProperties.put(Context.PROVIDER_URL, "remote://localhost:4447");
        jndiProperties.put(Context.SECURITY_PRINCIPAL, "user");
        jndiProperties.put(Context.SECURITY_CREDENTIALS, "pass");
        jndiProperties.put("jboss.naming.client.ejb.context", true);
        final Context context = new InitialContext(jndiProperties);

        traverseJndiNode("/", context);
        final UserFacadeRemote helloWorld = (UserFacadeRemote) context.lookup("writer-ear/writer-ejb-1.0/userFacade!" + UserFacadeRemote.class.getName());
        System.out.println("count " + helloWorld.count());
        UserDTO user = new UserDTO();
        user.setEmail("mail.google@gmail.com");
        user.setFirstname("Nina");
        user.setLastname("Ben");
        user.setPassword("Password");
        user.setRegisteredDate(new Date(System.currentTimeMillis()));
        helloWorld.save(user);
        context.close();

实际上save方法是假方法

 @Override
    public void save(UserDTO user) {
        System.out.println("Received object " + user.getFirstname());
        try {

            System.out.println("Saving object ");

        } catch (Exception e) {
            e.printStackTrace();
        }    
    }

在第二次查找中相同

// Using the proprietary JBoss EJB Client API
        final Properties ejbProperties = new Properties();
        ejbProperties.put("remote.connectionprovider.create.options.org.xnio.Options.SSL_ENABLED", "false");
        ejbProperties.put(Context.URL_PKG_PREFIXES, "org.jboss.ejb.client.naming");
        ejbProperties.put("remote.connections", "1");
        ejbProperties.put("remote.connection.1.host", "localhost");
        ejbProperties.put("remote.connection.1.port", 8080);
        //ejbProperties.put("remote.connection.1.connect.options.org.xnio.Options.SASL_DISALLOWED_MECHANISMS", "JBOSS-LOCAL-USER"); // needed for forcing authentication over remoting (i.e. if you have a custom login module)
        //ejbProperties.put("remote.connection.default.connect.options.org.xnio.Options.SASL_POLICY_NOPLAINTEXT", "false"); // needed for a login module that requires the password in plaintext
        ejbProperties.put("remote.connection.1.username", "user");
        ejbProperties.put("remote.connection.1.password", "pass");
        ejbProperties.put("org.jboss.ejb.client.scoped.context", "true"); // Not needed when EJBClientContext.setSelector is called programatically. ATTENTION: Client-Interceptor registration below does not work with this property! BUG?

        final EJBClientConfiguration ejbClientConfiguration = new PropertiesBasedEJBClientConfiguration(ejbProperties);
        final ConfigBasedEJBClientContextSelector selector = new ConfigBasedEJBClientContextSelector(ejbClientConfiguration);
        EJBClientContext.setSelector(selector);
        EJBClientContext.getCurrent().registerInterceptor(0, new ClientInterceptor());

        final Context ejbContext = new InitialContext(ejbProperties);
        final UserFacadeRemote ejbHelloWorld = (UserFacadeRemote) ejbContext.lookup("ejb:writer-ear/writer-ejb-1.0/userFacade!" + UserFacadeRemote.class.getName());
//        UserDTO user = new UserDTO();
//        user.setEmail("mail.google@gmail.com");
//        user.setFirstname("Nina");
//        user.setLastname("Ben");
//        user.setPassword("Password");
//        user.setRegisteredDate(new Date(System.currentTimeMillis()));
//        ejbHelloWorld.save(user);
        System.out.println("second count " + ejbHelloWorld.count());

我的客户端应用程序在tomcat下运行，所以什么错了？为什么我甚至可以从数据库中获取数据，但是当通过DTO时，客户端会失败。我探索了很多，旧版本的JBoss我没有做过同样的事情。

哦，我忘了设置我的DTO实现Serializable接口:(

public class UserDTO implements Serializable{

    private static final long serialVersionUID = 1L;

    private Long id;
