Unable to access my webapplication through port 80 ?

[Antrikssh]

Hello Everyone,

I have installed tomcat5.5 in my fedora 15 system at that time, I am new with the tomcat. So for installing it I have simply follow the instruction that i found over the net and set the port 8080 to access my web application. After that I have run my web application easily by using "http://localhost:8080/MyWebApp/WelcomePage.jsp".

But now I have to replace the "localhost:8080" by "localhost" for which i need to configure my application with port 80. I have googled for that and I found that after doing some changes in server.xml file of tomcat, I will easily get what I want.

I have changed the configuration like

<Connector port="8080" protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="8443" />
to
<Connector port="80" protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="8443" />
this step I found when I googled but when I restart tomcat and enter the address "http://localhost/MyWebApp/WelcomePage.jsp" on the url my request is rejected. After that I change the port like

<Connector port="80" protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="8443" />
to
<Connector port="8000" protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="8443" />
after restart tomcat I access my page by using "http://localhost:8000/MyWebApp/WelcomePage.jsp".

please help me out of this .

Thanks & Regards,

Antrikssh

Isn't Apache (=httpd) running in your machine?

E.g. on my machine httpd is listening on the default port:
[root@rmu40 ]# netstat -tulpn| grep -w 80
tcp 0 0 :::80 :::* LISTEN 14667/httpd

A process needs to run as root in order to listen in port 80. You did not state if you had taken care of this, so I assume you are still running it as some less privileged user. I think it also makes sense to have Tomcat and the applications running on top of it to run as a non-root user.

To access you Tomcat-based applications through port 80, you might install a simpler web server like Apache httpd to listen there and reverse proxy some requests (likely just ones starting with a specific URL path component) to an appropriate URL in the Tomcat that runs in port 8080 or some other less privileged port. This way the privileged process does not have as much responsibility and web application specific security problems would be somewhat less severe when they lack root privileges.
