我已经在web.xml中启用了CGI模块，并在context.xml中添加了preleged=true。将CGI文件放在我的应用程序中的web-INF/CGI/文件夹中。当尝试访问以下URL时，我得到"error=13，权限被拒绝"错误。(http://localhost:8080/cute/cgi-bin/cutecgi.cgi）
致命的: サーブレット cgi のServlet.service()が例外を投げました

这看起来像是CGI脚本的文件权限问题。Tomcat服务器运行的用户无法访问该文件，或者该文件本身没有该用户的执行权限。
尝试运行此命令以查看文件权限：
ls -l /var/lib/tomcat6/webapps/.metadata/.plugins/org.eclipse.wst.server.core/tmp1/wtpwebapps/cute/WEB-INF/cgi/cutecgi.cgi
