工作亮點：有關設置環境的問題

Question

我最近開始學習IBM Worklight。我已經設置了環境。

現在，我正在嘗試測試一個簡單的helloWorklight演示應用程序，但是我無法部署和構建該應用程序。盡管我遵循以下鏈接： http : //www.ibm.com/developerworks/mobile/worklight/getting- starts.html

我得到的錯誤是..嘗試在Worklight開發服務器上運行時：

另外我的工作燈控制台沒有打開，錯誤是：

Failed to deploy the application to Worklight server: Internal Server Error; Error 500: javax.servlet.ServletException: Filter [authenticationFilter]: 
Could not find required filter class - com.worklight.core.auth.impl.AuthenticationFilter.class 

Answer 1

驗證Worklight Development Server的server.xml文件。

檢查所有<library>標記，確保它們指向正確的路徑。

干杯！

Answer 2

明智的建議是驗證所有標簽。 首先，在哪里聲明“ shared.resource.dir”？ 無論它在哪里，它的路徑都應該是“ / usr / shared / resources”，在這里我們可以爬入子目錄並找到相應的庫。 我發現資源下面的db2目錄中包含的db2庫確實起作用，而worklight子目錄下面的db2目錄中的db2庫卻不起作用。 因此，我復制了狀況不佳的一個，然后將其替換為良好的一個... :-)，至少錯誤消息變得與眾不同。 :-D
