java.security.AccessControlException:访问被拒绝(java.io.FilePermission/usr/share/java/jsp-api-2.0.jar 读取)
我正在尝试将我的应用程序部署到 Debian Lenny 上的 Tomcat 5.5.我收到以下异常:
I am trying to deploy me application to Tomcat 5.5 on Debian Lenny. I am getting the following exception:
java.security.AccessControlException: access denied (java.io.FilePermission /usr/share/java/jsp-api-2.0.jar read)
我不知道该怎么办.
解决方案
将以下行添加到/etc/tomcat5.5/policy.d/04webapps.policy:
Add the following line to /etc/tomcat5.5/policy.d/04webapps.policy:
grant codeBase "file:/var/lib/tomcat5.5/webapps/mywebapp/-" { permission java.security.AllPermission; };
推荐答案
我闻起来像 SecurityManager.
I smells like an SecurityManager.
这是来自 Java 安全管理器的消息，而不是来自文件系统的消息.此 jar-archive 中的类尝试访问策略不允许的文件.
It is a message from the Java Security-Manager not from the filesystem. A class within this jar-archive tries to access a file, which is not allowed by the policy.
