я пытаюсь настроить веб-приложение, используя Spring MVC и Spring Data JPA на моем сервере Weblogic. Приложение работает нормально при первом развертывании его на сервере Weblogic, но когда я останавливаю приложение, имя jndi (jdbc / myDS) для моего источника данных исчезает из дерева JNDI на моем сервере Weblogic, а затем при попытке запустить приложение снова я получаю следующую ошибку:

Caused By: javax.naming.NameNotFoundException: Unable to resolve 'jdbc.myDS'. Resolved 'jdbc'; remaining name 'myDS'

m настраивает следующее при запуске в JPAConfiguratation.java:

м с помощью:

Весна 3.2.4. РЕЛИЗHibernate 4.2.6. ОкончательныйWeblogic 10.3.5

Нужно ли как-то вручную обрабатывать выключение приложения? Что может привести к исчезновению имени jndi из контекста сервера?

Вся помощь очень ценится!
