我为我配置了一个 tomcat 服务器来部署一个 JSP Web 应用程序，但是每次我启动该网站时，它都会在Tomcat Web Application Managerthat 中提示FAIL - Application at context path /appNameHere could not be started。现在我很困惑为什么会发生这种情况，有人可以解释并帮助为什么会发生这种情况吗？请参阅下面的详细错误。

如果您将加密数据存储到数据库中，请检查用于存储它的表列是否足够大以承载加密数据（始终大于原始数据）。如果您通过 HTTP 传输加密数据，请检查您在传输 BASE64 编码数据作为 URL 参数时是否存在问题（BASE64 使用 URL 参数中禁止使用的字符，例如“=”）。对于这些用途，请尝试使用十六进制输出。

该异常表明您的 JAVA 设置中没有 JCE 策略 Jar 文件。

从http://www.oracle.com/technetwork/java/javase/downloads/jce-7-download-432124.html下载它们

然后将罐子放在里面jdk/lib/security（链接）
