Question

I have enabled the CGI module in web.xml and added previleged=true in the context.xml. Placed the cgi file in the WEB-INF/cgi/ folder in my application. When trying to access the below URL I get “error=13, Permission denied” error. (http://localhost:8080/cute/cgi-bin/cutecgi.cgi)

This looks like an issue with the file permissions of your CGI script. Either the file cannot be accessed by the user that the Tomcat server is running as, or the file itself does not have execute permission for this user.

Try running this command to view the file permissions:

ls -l /var/lib/tomcat6/webapps/.metadata/.plugins/org.eclipse.wst.server.core/tmp1/wtpwebapps/cute/WEB-INF/cgi/cutecgi.cgi
