Java 8/JBoss 7 - 无法获取 bean 实例

Question

我正在将应用程序从 JBoss 5 升级到 7，但遇到了一个问题，即找不到已调用的 bean。

JBoss 实际正在寻找哪个 JNDI 绑定(bind)？

server.log(启动时)

WFLYEJB0473: JNDI bindings for session bean named 'ManagerLocal' in deployment unit 'subdeployment "Application-EJB.jar" of deployment "Application-EAR.ear"' are as follows:

    java:global/Application-EAR/Application-EJB/ManagerLocal!com.application.data.manager.local.ManagerLocal
    java:app/Application-EJB/ManagerLocal!com.application.data.manager.local.ManagerLocal
    java:module/ManagerLocal!com.application.data.manager.local.ManagerLocal
    java:global/Application-EAR/Application-EJB/ManagerLocal
    java:app/Application-EJB/ManagerLocal
    java:module/ManagerLocal

错误

计算 JNDI 名称的代码

private static String computeJNDIName(boolean isLocal, String beanName, String appName) {
        String name;

        if (isLocal) {
            name = appName + "/" + beanName + "/local";
        } else {
            name = appName + "/" + beanName + "/remote";
        }

        return name;
    }

Answer 1

不是最好的答案，例如它没有说明原因或推理，但我必须将其添加到我的 WAR 中的 JSF 支持 bean 中，以便当我升级到 EAP7 时它可以访问 EJB jar 中的 bean

@EJB(lookup="java:app/NEDtoBrsMigratorEJB/CustomerDeleterBean")
CustomerDeleterBeanLocal customerDeleterBean;

EJB 的 JNDI 绑定(bind)是:

java:global/NEDtoBrsMigratorEAR/NEDtoBrsMigratorEJB/CustomerDeleterBean!net.myco.brsupdater.engine.CustomerDeleterBeanLocal
java:app/NEDtoBrsMigratorEJB/CustomerDeleterBean!net.myco.brsupdater.engine.CustomerDeleterBeanLocal java:module/CustomerDeleterBean!net.myco.brsupdater.engine.CustomerDeleterBeanLocal java:global/NEDtoBrsMigratorEAR/NEDtoBrsMigratorEJB/CustomerDeleterBean java:app/NEDtoBrsMigratorEJB/CustomerDeleterBean java:module/CustomerDeleterBean

请注意，该示例注释用于 VM JNDI 查找。
