OK, you've got a few options here. This is all because a process can only bind to a port 1024 on Unix if it's running as root at the instant it binds. - Fix your current configuration. You're presently using mod_proxy_ajp to pass data between httpd and Tomcat , which is less mature than mod_jk. mod_jk takes a bit of setting up, but that would let you keep httpd if you want to. - Run Tomcat as root and set up an HTTP Connector on port 80. Not good for security! - Run Tomcat as non-root, set up an HTTP Connector on port 8080, and configure the Linux kernel firewalling to redirect port 80 to port 8080. Probably easier than setting up httpd, but it has a few irritating features like having to set proxyPort on the connector. - Start Tomcat using jsvc (see the section on Unix daemon at http://tomcat.apache.org/tomcat-6.0-doc/setup.html for details) and set up an HTTP Connector on port 80. This allows you to start Tomcat in a way that it can bind to port 80, but you then run it as an unprivileged user (using the --user option to jsvc). This is secure and doesn't require stuff like proxyPort. - Peter - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org thx for ur time and help... I finally found the solution... I cant run my app on 80 porto i have to use apache to forward request...
