我使用Netbeans构建了应用程序并且工作正常。但是当我部署在TOMCAT上时，我收到了这个错误

javax.servlet.ServletException: Servlet.init() for servlet Relay threw exception

任何想法。

看起来SecurityManager被配置为阻止类路径的修改。你在运行什么平台？并查看tomcat conf目录以获取安全管理器配置。

查看these docs以获取tomcat 5.5。

我认为您应该查看是否有文件$CATALINA_BASE/conf/catalina.policy，如果有，请添加以下内容：

permission jasper.reports "jasper.reports.compile.class.path", "write";

如果您在Relay servlet中写入该类路径，则不应使用jasper.reports，而应使用自己的包。

javax.servlet.ServletException：Servlet的Servlet.init（）Relay抛出异常
