javax.servlet.ServletException:servlet中继的servlet.init（）引发异常

我使用Netbeans构建了应用程序，它运行良好。但是当我在TOMCAT上部署时，我得到了这个错误

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。你在哪个站台上跑步？并查看安全管理器配置的tomcat conf目录

查看tomcat 5.5

我认为您应该检查是否有文件

$CATALINA_BASE/conf/CATALINA.policy

，如果有，请添加如下内容：

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

如果在中继servlet中写入该类路径，则不应使用jasper.reports，而应使用自己的包
