问题描述

我的Eclipse靛蓝，我用它来开发这个在我的电脑，然后在我的EC2实例也是如此，在亚马逊AWS，为GlassFish的我创建了一个JDBC连接池与使用JSF 2项目中使​​用Glassfish的3开源，我JPA实体管理器。

本地我的项目工程pretty的很好，但是当我部署的项目，并尝试执行相同的形式，它从一个在正在运行的GlassFish硬朗的同一个实例EC2上运行的数据库中获取某些值。

我收到此消息：

SERVERERROR：类javax.faces.el.E​​valuationException

我在寻找它，但我没有发现任何东西为止。

有一些配置，我768,16做它的工作原理？

解决方案

从您的堆栈跟踪：

  

产生的原因：java.lang.IllegalStateException：试图在一个封闭的EntityManagerFactory执行操作

<打击>这只能意味着你手动管理（与的EntityManager ）而不是的EntityManagerFactory 让容器中只是 @PersistenceContext 。

做的工作

在的EntityManagerFactory 是intented要在Web应用程序的启动创建只有一次，在整个Web应用程序的生命周期重用和Web应用的停机关闭。它不应该被某处中途封闭或序列化并再用于下一个重启循环

既然你显然是针对Glassfish的，我会强烈建议你自己来管理它，而是让Glassfish的做的工作。你最终要简单得多EJB code没有所有的麻烦手动管理的事务。

更新：您的EJB code看上去一切正常。这更可能是Glassfish的错误或配置错误：

I have Eclipse Indigo that I use to develop a JSF 2 project using Glassfish 3 Open Source, this in my computer then in my EC2 instance too, in Amazon AWS, for both Glassfish's I created a JDBC Connection Pool to use with my JPA Entity Manager.

Locally my project works pretty fine, but when I deploy the project and try to execute the same form, which gets some values from the database that is running in the same instance EC2 that is running the GlassFIsh tough.

I receive this message:

serverError: class javax.faces.el.EvaluationException

I'm searching about it, but I don't found anything so far.

There's some configuration that I shoud do for it works ?

EDIT 2: This is how I'm using the EntityManager:

@Stateless(mappedName = "logEAO")
@LocalBean
public class LogEAO {
    @PersistenceContext
    private EntityManager em;

    public LogEAO() {}


    public Log find(int id) {
        return em.find(Log.class, id);
    }
    // ..

解决方案

From your stacktrace:

Caused by: java.lang.IllegalStateException: Attempting to execute an operation on a closed EntityManagerFactory.

This can only mean that you're manually managing the EntityManagerFactory (and EntityManager) instead of letting the container do the job by just @PersistenceContext.

The EntityManagerFactory is intented to be created only once on webapp's startup, reused throughout the entire webapp's lifetime and closed on webapp's shutdown. It should not be closed somewhere halfway or be serialized and reused for a next restart cycle.

Since you're apparently targeting Glassfish, I would strongly recommend to not manage it yourself, but letting Glassfish do the job. You end up with much simpler EJB code without all the hassle to manage transactions manually.

Update: Your EJB code looks all right. This is more likely a Glassfish bug or misconfiguration:
