Question

我正在编写一个带有状态bean的EJB代码。

HelloStatefulBean打包在.EAR文件中，EjbClient打包在.WAR文件中，两个存档都部署在JBOSS-EAP-6.2服务器中。 EjbClient.java文件通过REST-API（/ test / execute）

调用

我从EjbClient.java类调用EJB。从客户端到EJB的第二个方法（sayHi（））的调用失败，使用“NoSuchEJBException”，这种行为似乎有点奇怪，因为在相同的上下文中我能够成功调用第一个方法（sayHello（））。 / p>

请让我知道，我错过了什么？

这是我的代码：

Stateful bean:
    @Stateful(name = "helloejb")
    @StatefulTimeout(unit = TimeUnit.MINUTES, value = 1)
    @TransactionManagement((TransactionManagementType.BEAN))
    public class HelloStatefulBean extends CloudProvider implements IHelloBean
    {
        public String sayHello(String name)
        {
            String str = "Hello " + name;
            System.out.println(str);
            ....
            ...
            ..
            .
            return str;
        }

        public void sayHi(String str)
        {
            System.out.println("Hi " + str);
            ....
            ...
            ..
            .
        }
    }

Remote Interface:
    @Remote
    public abstract interface IHelloBean
    {
        public abstract String sayHello(String paramString1);

        public abstract void sayHi(String paramString1);
    }

EJB Client:
    @Path("/test")
    public class EjbClient
    {
        @POST
        @Path("/execute")
        public Response execute()
        {
            String lookupName = "java:global/hello/hello/helloejb!com.test.beans.ifc.IHelloBean";
            Context initialContext = new InitialContext();
            LOGGER.info("Looking-up the EJB with name: " + lookupName);
            IHelloBean objRef = (IHelloBean)initialContext.lookup(lookupName);
            LOGGER.info("Lookup successful.");
            String msg = objRef.sayHello("XYZ");

            objRef.sayHi(msg);   // Fails on this method call with NoSuchEJBException
        }

    }

在使用URL： http://{JBOSS-SERVER-IP}:8080/api/test/execute 触发REST-API时，将调用REST-API并且EJB的查找也是成功的。此外，“sayHello（）”方法也被成功调用，但在从EjbClient调用“sayHi（）”方法时，应用程序失败，异常：

如果删除@StatefulTimeout解决NoSuchEJBException异常，并假设您在bean保持活动（1分钟）的时间段内调用第一种和第二种方法，则可能是Container已经关于这个注释的一些问题。我在谷歌做了一些研究，但我没有发现任何关于这个问题的错误。

关于你的评论，答案是否定的，在调用第二个方法之前进行新的查找不是解决方案，因为你将得到一个不同的ejb引用，具有不同的状态。它的工作原理是因为在您的示例中您不是在管理状态，但在实际要求下，您需要保持相同的ejb引用。（这是有状态的原因）

对于有状态bean，远程EJB调用第二次失败
