Dependency injection Jboss AS 7-依赖项注入

我试图在JBossAS7中使用依赖注入，我遇到了巨大的困难

我已经设置了一个EAR，它包含一个EJBJAR和一个war

war包含一个richfaces web应用程序

我试图将EJB从EJB jar注入faces管理的bean，代码如下：

 public class UserController {

    @EJB(mappedName="UserService")
    private UserFacadeService userService;

    public String getService(){
        if(userService == null){

但是，当我部署jboss时，会将错误放在控制台中：

请协助

问题可能在于WAR没有定义对EJB jar的依赖关系。如果没有，最好为EJB jar文件定义WAR的META-INF/MANIFEST.MF类路径条目

您可能还需要检查配置文件，并确保

标记设置为false

<subsystem xmlns="urn:jboss:domain:ee:1.0" >            
  <ear-subdeployments-isolated>false</ear-subdeployments-isolated>
</subsystem>

假的

上还有一些不错的文档。

首先，确保在您的war中有文件META-INF/MANIFEST.MF，并且有行类路径：GoodByeJohnEJB-1.0-SNAPSHOT.jar

然后在UserController类中，尝试删除mappedName，只添加EJB注释

或者，您可以使用以下选项：

InitialContext ic = new InitialContext();
UserFacadeService userService = (UserFacadeService )ic.lookup("java:global/GoodByeJohnEAR/GoodByeJohnEJB-1.0-SNAPSHOT/UserFacadeBean");

您是从IDE运行它吗？如果是，则展开服务器twistie并查看它们是否都已实际部署。似乎war文件不在那里。另外，当您启动服务器时，何时会出现此错误？您能否提供有关

UserFacadeService

和

UserFacadeBean

注释的更多信息？您是否从IDE运行它？如果是，则展开服务器twistie并查看它们是否都已实际部署。似乎war文件不在那里。另外，当您启动服务器时，何时会出现此错误？您能否提供有关
