EJB注入失败部署 [英] EJB Injection failure on deploy

问题描述

我有一个问题exxh EJB的。

I've got a problem exxh EJB's.

首先，我的设置：我正在使用GlassFish& JEE6。我得到一个REST-Service打包成WAR，一个bean作为EJB-Jar打包。他们不在EAR内。
应该通过@EJB从REST-WAR使用EJB，但是当我尝试部署WAR时，GlassFish会显示此错误：

First of all, my setup: I am using GlassFish & JEE6. I got a REST-Service packaged as a WAR and a bean packaged as an EJB-Jar. They are not inside an EAR. The EJB should be used from the REST-WAR via @EJB, but when I try to deploy the WAR, GlassFish shows this error:

部署：部署应用程序时出现异常[exx-upload-1.0]：无法解析引用局部ejb-ref name = com.ex.exx.model.FileUpload / ocr，Local 3.x interface = com.ex.exx.api。 IOCRService，EJB链接= NULL，查找=，= mappedName，JNDI名称=，= RefType的会话。请参阅server.log了解更多详细信息。

Error occurred during deployment: Exception while deploying the app [exx-upload-1.0] : Cannot resolve reference Local ejb-ref name=com.ex.exx.model.FileUpload/ocr,Local 3.x interface =com.ex.exx.api.IOCRService,ejb-link=null,lookup=,mappedName=,jndi-name=,refType=Session. Please see server.log for more details.

（EJB已部署之前没有任何错误）。

(The EJB was deployed before without any erros).

我不知道为什么。以下是EJB代码：

I have no clue why. Here is the EJB Code:

接口：

@Local
public interface IOCRService {
    public String performOCRonImage(BufferedImage input);
}

和实现：

@Stateless
@LocalBean
public class OCRScanner implements IOCRService  {

    private Logger logger = Logger.getLogger(this.getClass().getName());
    private final static String NOT_RECOGNIZED = "Can not regocnize text";
    /**
     * Default constructor.
     */
    public OCRScanner() {
        logger.log(Level.INFO, "### OCR SCANNER BUILD" + this);
    }



    public String performOCRonImage(BufferedImage input) {
    logger.log(Level.INFO, "### OCR SCANNER CALLED" + this);
    }

    ...

这里是重要的在WAR中的一部分：

And here is the important part in the WAR:

public class FileUpload {
private final File PROPERTIES_FILE = new File(
        "fileUploadProperties.properties");
private final String PARAMETER_NAME = "file";
private final Logger logger = Logger.getLogger(this.getClass().getName());


@EJB
    private IOCRService ocr;
    public Response uploadFile(...) {
    // do some stuff
    logger.log(Level.INFO, "### EJB" + ocr.toString())
    }
Anny suggestions? I can not find my failure here.

推荐答案

通过用@Remote替换@Local来解决这个问题。
但是，我不满意，因为我不明白为什么。

Solved this, by replaceing @Local with @Remote. This works, however, I am not satisfied as I do not understand why.
