Question

我写信给maven-projects部署到wildfly 11。我尝试向远程ejb客户端抛出异常，但我总是得到另一个异常（不是抛出的异常）。我想在客户端捕获特定的自己编写的异常（例如NotLoggedInException）

以下最小示例只会抛出超类Exception（当我不抛出异常时，一切都按预期工作，因此例如pom中没有丢失的依赖项）：

接口：

package de.fhac.ks.ss18;

import javax.ejb.Remote;

@Remote
public interface ExceptionToClientBeanRemote {

    void foo() throws Exception;

}

豆：

package de.fhac.ks.ss18;

import javax.ejb.Stateless;

@Stateless
public class ExceptionToClientBean implements ExceptionToClientBeanRemote {

    @Override
    public void foo() throws Exception {
        System.out.println("foo");
        throw new Exception();
    }


}

客户端：

package de.fhac.ks.ss18;

import java.util.Hashtable;

import javax.naming.Context;
import javax.naming.InitialContext;
import javax.naming.NamingException;

public class Client {

    private static <T> T lookup(String uri, Class<T> cl) throws NamingException {
        final Hashtable<String, String> jndiProperties = new Hashtable<>();
        jndiProperties.put(Context.INITIAL_CONTEXT_FACTORY, "org.wildfly.naming.client.WildFlyInitialContextFactory");
        jndiProperties.put(Context.PROVIDER_URL, "remote+http://localhost:8080");
        final Context context = new InitialContext(jndiProperties);
        return cl.cast(context.lookup(uri));
    }

    public static void main(String[] args) {
        ExceptionToClientBeanRemote exceptionToClientBean = null;
        try {
            String uri = "ejb:/ExceptionToClient-ejb/ExceptionToClientBean!de.fhac.ks.ss18.ExceptionToClientBeanRemote";
            exceptionToClientBean = lookup(uri, ExceptionToClientBeanRemote.class);
        } catch (NamingException e) {
            e.printStackTrace();
        }
        try {
            exceptionToClientBean.foo();
        } catch (Exception e) {
            e.printStackTrace();
        }

    }

}

我得到了Stacktrace：

有人可以帮忙吗？
