我将我的 JBoss AS7.1.1 (standalone.xml) 配置为接受远程处理，但未打开 4447 端口。我的standalone.xml：
<subsystem xmlns="urn:jboss:domain:remoting:1.1">

</subsystem>
<interfaces>
<interface name="mine">

客户端程序：
public class Homework4EJB3Client {
/**

private static IMailService lookupRemoteStatelessMessaging() throws NamingException {

jndiProperties.put(Context.URL_PKG_PREFIXES, "org.jboss.ejb.client.naming");
final Context context = new InitialContext(jndiProperties);
// The app name is the application name of the deployed EJBs. This is typically the ear name

final String appName = "";
// This is the module name of the deployed EJBs on the server. This is typically the jar name of the

// let's do the lookup

@SuppressWarnings({ "unchecked", "rawtypes" })
public static void main(String[] args) {

我使用了 jboss-ejb-client.properties：
endpoint.name=client-endpoint
remote.connectionprovider.create.options.org.xnio.Options.SSL_ENABLED=false
remote.connections=default
remote.connection.default.host=192.168.1.25
remote.connection.default.port = 4447
remote.connection.default.connect.options.org.xnio.Options.SASL_POLICY_NOANONYMOUS=false
remote.connection.default.username=quickstartUser
remote.connection.default.password=quickstartPassword
在服务器端 Java 代码：
@Named
@Stateless
@Remote(IMailService.class)
public class MailService implements IMailService {
@Inject
private EntityManager em;
@Override
public void sendMail() {
System.out.println("EntityManager:"+em);
System.out.println("Mail sent");
}
@Override
public String getMail() {
return new String("Mail sent");
}
}
客户端使用 jboss-client.jar 和服务器导出 java:jboss/exported/Homework4Quartz/MailService!hu.infokristaly.homework.quartz.middle.service.IMailService 接口。
所以，一切都很好，如果我将 localhost 用于 remote.connection.default.host，但如果我使用远程 ip 则会失败

我也在另一边使用了 add-user (application-users.properties, quickstartUser, quickstartPassword, guest)。如何在不同的机器上运行客户端和服务器？
