我試圖追查我的應用程序的一部分突然停止工作的原因。我使用Weblogic 8.1.4.0和Hibernate來運行Spring 1。報告生成器是失敗的部分，首先在我們的生產服務器上，然後在週五嘗試時在dev和qa服務器上。我沒有對代碼做任何修改，但是現在我在映射查詢的compile語句中得到了Missing Data Source異常。唯一改變的是數據庫中的一些記錄，但它們是相當簡單的變化，我懷疑會產生影響。我還得到了以下錯誤週五身邊的時候，這兩個開發的應用程序可能失敗：ContextLoader：上下文初始化失敗
這裏是開發服務器日誌中的錯誤：
04-06 14:31:34 ERROR [main] org.springframework.web.context.ContextLoader: Context initialization failed
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'myDataSource' defined in ServletContext resource [/WEB-INF/applicationContext.xml]: Initialization of bean failed; nested exception is javax.naming.LinkException:
而且還有一個類似的一個約10從我部署到QA服務器幾分鐘後。
它指的是WebLogic中定義的數據源和連接池。我已經檢查並測試了連接，並且似乎沒有任何問題。
可能會發生什麼會導致這種情況？我甚至恢復到上週的生成，以確保它不是一個代碼的變化，但出現所需的相同的數據源例外：
04-07 16:15:04 DEBUG [ExecuteThread: '14' for queue: 'default'] org.eei.survey.data.RegionDataDAO$NERCRegionMappingQuery: RdbmsOperation with SQL [{call prc_NERCRegions_get}] compiled

任何幫助，將不勝感激。
更新：這是錯誤的完整堆棧跟蹤：

你能獲得更多的堆棧跟蹤嗎？ – chrislovecnm 2012-04-08 18:46:44
已添加完整的堆棧跟蹤。 – jwBurnside 2012-04-08 18:59:49
你是否定義了你的數據源bean？ – chrislovecnm 2012-04-08 19:15:48
