项目在线时，Manager Bean不返回 [英] Manager Bean do not returns when the project is online
问题描述
我有一个使用JPA的JSF项目，我这样做:从mysql数据库中检索一些数据，然后将数据绘制在图表中.
I have a JSF project working with JPA, I do this : retrive some data from mysql database then plot the data in a chart.
在本地工作正常，如您在此处看到的:
Locally works pretty fine, as you can see here:
因此，我将项目部署在运行于EC2实例中的GlassFish 3 Open Source中，然后再次尝试执行相同的操作，但是ManagedBean似乎无法正确返回页面:
So I deploy the project in my GlassFish 3 Open Source, which is running in a EC2 instance, then I try to make the same operation again but it seems the ManagedBean do not returns to the page correctly:
这是我的ManageBean:
This is my ManageBean :
@ManagedBean(name="reportc")
@SessionScoped
public class ReportControl implements Serializable {
private static final long serialVersionUID = 3269125738504434502L;
@EJB LogEAO logEAO;
private int quantity;
@NotNull(message="informe um intervalo")
private String time;
@NotNull(message="informe um ponto")
private String point;
private Map<String, Object> data = new HashMap<String, Object>();
@PostConstruct
public void init(){
quantity = 1;
}
public String getDataAsJson() {
return new Gson().toJson(data);
}
public String generateReport(){
this.setTitles();
this.getValues(getLog());
return "/showroom/report.xhtml?faces-redirect=true";
}
.. methods and get's and set's
我已经查看了server.log，看是否有问题，但似乎一切都很好.
I already look in into my server.log to see if there's something wron but it seems everything is alright.

我真的不知道为什么会这样，除了这是我第一次尝试部署同时使用JPA和JSF的项目. 该怎么做?
I really don't know why this is happening, besides is my first time trying to deploy a project which use JPA and JSF together. What could be doing this ?
还有一件事，在本地模式下，当我单击以生成报告时，它需要花费几秒钟才能进入数据库，进行数学运算并返回到我的页面，但是在生产模式下，当我单击以生成报告时，它就会刷新页面上，为什么会发生这种情况? 我真的需要知道为什么……请帮帮我.
Just one more thing, in local mode when I click to generate the report it takes some seconds to go to the database, make the maths and return to my page, but when it's in production mode when I click to generate the report it just refresh the page, why is that happening ? I really need to know why ... help me out guys, please.

推荐答案
解决方案是:
我必须向MySQL中的某些用户授予权限，在MySQL中启用远程连接，将JDBC驱动程序放入glassfish_installation\glassfish\modules\中并重新启动它，初始化logEAO并将注释@Table(name="table_name")放进去，因为它取决于每个文件可以在运营系统中找到系统，如下所示:
I had to give permissions to some user in MySQL, enable the remote connection in MySQL, put JDBC driver in glassfish_installation\glassfish\modules\ and restart it, initialize the logEAO and put the annotation @Table(name="table_name") because it depends of each file system in operationals system as can be seen here:
