Looks like the SecurityManager is configured to block modifications of the class path. What platform are you running on? And have a look at the tomcat conf directory for security manager configuration.
看起来 SecurityManager 被配置为阻止类路径的修改。你在什么平台上运行？并查看安全管理器配置的 tomcat conf 目录。
Check out these docsfor tomcat 5.5.
I think you should check out whether you have a file $CATALINA_BASE/conf/catalina.policy, and if so add something like:
我认为您应该检查是否有文件$CATALINA_BASE/conf/catalina.policy，如果有，请添加以下内容：
permission jasper.reports "jasper.reports.compile.class.path", "write";
If you write to that class path in your Relay servlet you should not use jasper.reports but your own package.
如果您在 Relay servlet 中写入该类路径，则不应使用 jasper.reports 而应使用您自己的包。
