作爲JBoss 7 - 依賴注入

林試圖使用依賴注入的JBoss AS中7，並具有巨大的困難IM。作爲JBoss 7 - 依賴注入

我有安裝它同時包含EJB瓶和戰爭EAR。

戰爭包含RichFaces的Web應用程序。

林試圖注入從EJB JAR的EJB成面託管bean用下面的代碼：

public class UserController { 

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

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

然而，當我部署的JBoss把錯誤信息在控制檯：

你是從IDE運行呢？如果是的話然後展開服務器摺疊標記，看看他們兩個其實都是deployed.Seems就像打仗文件沒有there.Also你什麼時候得到這個錯誤，在當你啓動服務器？ – Shahzeb

你能否提供更多關於'UserFacadeService'和'UserFacadeBean'註釋的信息？ – Thor

它看起來像這個問題可能是你的戰爭沒有爲定義了EJB JAR的依賴。如果沒有，最好爲您的EJB jar文件定義您的WAR的META-INF/MANIFEST.MF的Class-Path條目。

您還可能要檢查您的配置文件，並確保<ear-subdeployments-isolated />標籤設置爲false。

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

class loading in JBoss AS7也有一些體面的文件。

首先，確保你的戰爭中，你有文件META-INF/MANIFEST.MF，並有有行類路徑：GoodByeJohnEJB-1.0-SNAPSHOT.jar，

然後在您的UserController類中，嘗試刪除mappedName，只需添加EJB註釋。

或者，您可以使用此：

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