無法在Tomcat中啓動JSP

Question

我爲我配置了一個tomcat服務器來部署JSP Web應用程序，但每次我將啓動該網站時，它會在Tomcat Web Application Manager中提示FAIL - Application at context path /appNameHere could not be started。現在我很困惑爲什麼會發生這種情況，有人可以解釋和幫助爲什麼會出現這種情況嗎？請看下面的詳細錯誤。

是有什麼毛病我的聽衆？提前致謝！

Answer 1

該異常表示您沒有JCE策略Jar文件進入您的JAVA設置。

從http://www.oracle.com/technetwork/java/javase/downloads/jce-7-download-432124.html

下載他們然後把罐子裏面jdk/lib/security（link）

Answer 2

如果要存儲的加密數據到數據庫中，請檢查您所使用的表列來存儲它是足夠大以容納加密數據（始終大於原始數據）。如果您通過HTTP傳輸加密數據，請檢查您是否將BASE64編碼數據作爲URL參數傳輸出現問題（BASE64使用URL參數中禁用的字符，例如「=」）。對於這些用途，請嘗試使用十六進制輸出。
