Question

我正在将一个应用程序从JBoss 5升级到7，但是我一直遇到一个问题，即它无法找到被调用的bean。

JBoss实际上正在寻找哪个JNDI绑定？

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;
    }

不是最好的答案，例如它没有说明原因或理由，但是我必须将其添加到WAR中的JSF支持bean中，以便在升级到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，该示例注释适用于VM JNDI查找。
