Как создать источник данных в Weblogic с помощью java

Question

Мне нужно написать код Java для создания источника данных в Weblogic с использованием API. Я нашел API из Weblogic. Но я не могу найти какую-либо пробную реализацию. Может кто-нибудь, пожалуйста, помогите мне здесь? Я пытаюсь использовать ниже API:

DataSourceManager dsManager = DataSourceManager.getInstance(); 
    dsManager.createAndStartDataSource(jdbcImpl, appName, moduleName, compName, jdbcCtx, classLoader) 

Заранее спасибо.

Вы должны использовать управление интерфейсом сценарий WLST для этой операции, как описано в этом фрагменте кода:
