org.apache.jasper.JasperException: java.security.AccessControlException
今天开始将spring整合到GAE上，竟然出现了问题。根据网络资料是不要使用spring-all-in-one jar，主要是javax.naming等问题，我也特别留意了一下，只用了需要用的spring的几个jar。报错如下Struts has detected an unhandled exception:
Messages: access denied (java.io.FilePermission jar:file:\C:\Documents and Settings\Xredman\workspace\neil-blog\war\WEB-INF\lib\struts2-core-2.1.8.1.jar read)
java.security.AccessControlException: access denied (java.io.FilePermission jar:file:\C:\Documents and Settings\Xredman\workspace\neil-blog\war\WEB-INF\lib\struts2-core-2.1.8.1.jar read)
File: java/security/AccessControlContext.java

java.security.AccessController.doPrivileged(Native Method)
这肯定是权限问题了，可是问题出在哪里呢？基本上没有头绪
后来根据GAE的讨论记录寻找了一种解决方案，就是更改struts.xml
<constant name="struts.devMode" value="true" />
将开发模式设置为false即可
