無法在IBM WCS中創建控制器命令7

Question

我是IBM WCS的新手。我正在使用IBM Infocenter學習wcs。他們提到了一些教程，介紹瞭如何創建控制器命令和所有其他任務。我在WebsphereCommerceServer ExtensionLogic下創建了一個用戶定義的Controller命令（FeedBackCmd），我遵循了所有步驟，例如在CMDREG表和struts-config-ext.xml中創建條目，然後使用管理控制檯更新註冊表，但是當我調用該命令時，下面的錯誤

所以任何人都可以請告訴我我該怎麼做？ 感謝和問候

請確保您的界面中指定了默認類。

，如：

static final String defaultCommandClassName = "com.ibm.commerce.sample.commands.MyNewControllerCmdImpl"; 

如果CMDREG找到指定的商店沒有進入，它會爲您在界面中提到的上述實現類。確保該條目在界面中。

謝謝，
