Answer 1

您应该查找的 JNDI 地址是

java:app/org.wso2.carbon.custom.ejb-1.0-SNAPSHOT/HelloBean

java:appspecifies the app namespace，所以这假设您从 bean 所在的同一个应用程序访问这个 bean。

经过长时间的搜索，我解决了这个问题。这是因为 glassfish 中的 classloder 问题。所以添加了一个方法来解决类定位问题然后它的工作正常。

 Thread currentThread = Thread.currentThread();
    ClassLoader oldClassLoader = currentThread.getContextClassLoader();
    try {
        //switching the classloader to prevent class loading glassfish classloading issues
        currentThread.setContextClassLoader(getClass().getClassLoader());
        //method to run
        callEJBStateful(messageContext);
    } catch (Exception e) {
        handleException("Error calling EJB Service from EJBConnector", e, messageContext);
    } finally {
        if (oldClassLoader != null) {
            //resetting the classloader
            currentThread.setContextClassLoader(oldClassLoader);
        }
    }
