您好，我是 RMI 和 Glassfish 的新手，需要这方面的帮助。
我的示例代码:
package test.JNDITest;
import javax.ejb.Remote;
import java.io.Serializable;
@Remote
public interface Foo extends Serializable {
public int testMethod(int number);
public MyNewObject createMyNewObject();
}
package test.JNDITest;
import java.io.Serializable;
public interface MyNewObject extends Serializable{
public void testMethod2();
}
package test.JNDITest;
import javax.ejb.Singleton;
@Singleton
public class FooImpl implements Foo{
@Override
public int testMethod(int number) {
return number + 1000;
}
@Override
public MyNewObject createMyNewObject() {
return new MyNewObjectImpl();
}
}
package test.JNDITest;
public class MyNewObjectImpl implements MyNewObject {
@Override
public void testMethod2() {
}
}
我将其打包并部署在 Glassfish 3 上。现在我尝试测试它:
import test.JNDITest.Foo;
import test.JNDITest.MyNewObject;
import javax.naming.Context;
import javax.naming.InitialContext;
import java.util.Properties;
public class TestMath {
public static void main(String[] args) throws Exception {
Properties properties = new Properties();
properties.setProperty("org.omg.CORBA.ORBInitialHost", "localhost");
Context context = new InitialContext(properties);
Foo x = (Foo) context.lookup("java:global/JNDITest-ear-1.0-SNAPSHOT/JNDITest-ejb-1.0-SNAPSHOT/FooImpl!test.JNDITest.Foo");
System.out.println(x.testMethod(42));
MyNewObject x2 = x.createMyNewObject();
}
}
testMethod 工作正常，但是当我使用 createMyNewObject 时，我有:

这是我的第一篇文章，请温柔:)
最佳答案
您的MyNewObjectImpl类需要扩展UnicastRemoteObject，或者以其他方式导出。目前它根本不是远程对象，因为它没有导出，所以它被序列化到注册表和客户端，这根本不是您想要的。
关于jakarta-ee - 无法远程调用方法，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/10169462/
