（AS7）在参数中使用代理的CDI bean调用远程EJB方法时出错 [英] (AS7) Error calling remote EJB method with proxified CDI bean in parameter

问题描述

我可以在参数方法中使用CDI bean调用远程EJB方法吗？

Can I call a remote EJB method with CDI bean in parameter method?

像这样：

我有一个 LoggedUserProducer.java ，它从数据库中产生了一个用户。

I have a LoggedUserProducer.java thats produces a User from the database.

public class LoggedUserProducer {

    @Produces
    @SessionScoped
    @LoggedUser
    public User produceLoggedUser() throws Exception {
        ... //load user from database with a request token
        return user;
    }
}

我有一个JSF Bean，可以调用EJB ：

And I have a JSF Bean thats make the EJB call:

CarController.java

@Named
@ViewScoped
public class CarController implements Serializable {

    @Inject //I have a producer to create the EJB proxy
    private RepairRemote repairRemote; //My remote EJB

    @Inject
    @LoggedUser
    private User loggedUser; //my User produced by LoggedUserProducer

    private Car car;

    public void repairCar() throws Exception {
        ... //some actions...

        Repair repair = new Repair(this.car)
        repair.setPerformedBy(loggedUser); //setting my proxified cdi bean into a POJO

        repairRemote.repair(repair); //here throws ClassNotFoundException;
    }

和例外：

Caused by: java.lang.ClassNotFoundException: com.mycompany.portalcarweb.client.model.User$Proxy$_$$_WeldClientProxy from [Module "deployment.portalcarweb.war:main" from Service Module Loader]

我不知道为什么我的远程EJB找不到类 com。 mycompany.portalcarweb.client.model。 User $ Proxy $ _ $$ _ WeldClientProxy

I don't know why my remote EJB can't find the class com.mycompany.portalcarweb.client.model.User$Proxy$_$$_WeldClientProxy

我的 User.java 部署在JBoss 7模块中。
我的EJB客户端和服务器在 WEB-INF 文件夹中有 jboss-deployment-structure.xml 声明访问该类的正确模块。

My User.java is deployed in a JBoss 7 module. My EJB client and server have the jboss-deployment-structure.xml in WEB-INF folder and declaring the correct module to access this class.

谢谢（抱歉，我的英语）。

Thanks (sorry my english).

更新

我的两个Web应用程序打包在WARs文件中。

My two webapps are packaged in WARs file.

推荐答案

您的JSF Bean不受CDI管理（@ViewScoped仅适用于JSF），除非您使用的是Seam 3之类的东西， CODI或编写了自己的新@ViewScoped。

Your JSF bean isn't being managed by CDI (@ViewScoped is JSF only), unless you're using something like Seam 3, CODI or wrote your own new @ViewScoped.

编辑：实际上，这可能不是bug。每次处理远程EJB时，都必须传递一个副本，这是最好的方法。

Actually, it probably isn't a bug. You'll have to pass a copy, any time you're dealing with remote EJBs copies are the best way to go.
