无法在Tomcat中启动JSP

Question

我为我配置了一个tomcat服务器来部署JSP Web应用程序，但每次我将启动该网站时，它会在Tomcat Web Application Manager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，有人可以解释和帮助为什么会出现这种情况吗？请看下面的详细错误。

是有什么毛病我的听众？提前致谢！

Answer 1

该异常表示您没有JCE策略Jar文件进入您的JAVA设置。

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

下载他们然后把罐子里面jdk/lib/security（link）

Answer 2

如果要存储的加密数据到数据库中，请检查您所使用的表列来存储它是足够大以容纳加密数据（始终大于原始数据）。如果您通过HTTP传输加密数据，请检查您是否将BASE64编码数据作为URL参数传输出现问题（BASE64使用URL参数中禁用的字符，例如“=”）。对于这些用途，请尝试使用十六进制输出。
