Question

这个简单的Wicket页面在GlassFish 3.1.2.2服务器中运行良好，但在GlassFish 4.0中部署时不起作用。非常重要的是要注意不包含@Resource注释的其他页面工作正常。

public class IndexPage extends WebPage {

  // this EJB injection works as expected
  @EJB(name = AnyManager.NAME)
  AnyManager anyMgr;

  // this JNDI Resource is defined as java.util.Properties at JNDI/Custom Resources of GlassFish admin console
  // this resource can be looked up using normal InitialContext.doLookup() method
  @Resource(name = "anyResource")
  Properties config;

  public IndexPage(final PageParameters p) {
    super(p);
  }
}

它给出以下例外：


Last cause: org.apache.wicket.proxy.ILazyInitProxy not found by org.glassfish.hk2.external.cglib [27]
WicketMessage: Can't instantiate page using constructor 'public hu.app.IndexPage(org.apache.wicket.request.mapper.parameter.PageParameters)' and argument ''. An exception has been thrown during construction!

请参阅堆栈跟踪（从IndexPage构造函数的第一行开始）：

在进行了大量的Google搜索之后，我有一个想法尝试在我的一个经理bean中进行注入我为它定义了一个简单的getter。请参阅以下几行：

@Local
public interface AnyManager extends EntityManager {
  public static final String NAME = "ejb/AnyManager";
  Properties getConfig();
}

@Stateless(name = AnyManager.NAME)
public class AnyManagerImpl extends AbstractEntityManager implements AnyManager {

  @Resource(name = "iOIRConfig")
  Properties config;

  @Override
  public Properties getConfig() {
    return config;
  }
}

我已经改变了我的Wicket页面：

public class IndexPage extends WebPage {

  @EJB(name = AnyManager.NAME)
  AnyManager anyMgr;

  // so I have commented out
  // @Resource(name = "anyResource")
  Properties config;

  public IndexPage(final PageParameters p) {
    super(p);

    // and get the value from one of my EJB manager class
    config = anyMgr.getConfig();
  }
}

这对我有用。我不喜欢这种类型的解决方案，我仍然在寻找真正的解释和解决方案。在GlassFish 4中可以改变什么导致这种症状？我在GlassFish 3中没有这种奇怪的效果。

我为GlassFish 3和GlassFish 4都安装了干净。

我的应用程序是一个EAR应用程序，它包含一个EJB.jar，WEBAPP.war和一个带有共享公共jar的lib /文件夹。也许这是某种类加载器问题，因为EJB和WebApp位于不同的文件夹中？但为什么@EJB有效而@Resource没有？

也许这是一个Java EE 7实现问题或GlassFish 4中的简单错误？

任何帮助都会很好。

在GlassFish 4 @Resource注释上使用Wicket的JavaEE 6应用程序失败
