i was using tomcat6 in windows. i copied the same tomcat6 folder in my home folder in ubuntu. i set the java_home variable and started tomcat using
tomcat6/bin#bash startup.sh
it started fine.but when i entered http://localhost:8080/ in the browser, it said Firefox can't establish a conn. to a server at 8080.
when i viewed the catalina.out in logs, i found,
java.net.BindException, permission denied:80.
what can i do for that? plz anyone answer.

Tomcat didn't start. You probably can't start the service, unless you're root. SU into the root user, and start it there.

And PLEASE spell out your words.

I have a doubt, Shall We use same Windows source in Linux?

Obviously not...Windows programs work on Windows only. And what does this have to do with jayrmca's original question?? Don't hijack someone elses thread...open your own.

Again the server started normally.but it doesn't work in browser.
but this is the log:

@jayrmca: I don't see anything about failure to bind to port 80 in that log snippet.

What are you trying to do? Just run tomcat on port 8080? (I'm asking because you appear to have an ajp connector configured.)

In any case, post your server.xml (sans comments), and the output of # netstat -ltn after starting the service.

I do not have any intention to hijack others thread, but in this circumstances the answer for my question will clear the different between windows and linux source.

This sound like that he copied tomcat windows folder in ubuntu.

The above is the main reason why i have posted the question on this same thread.

The apache tomcat download is independent of the OS... All the necessary files have a .bat type for windows and a .sh type for linux based distros. There is a difference only when you choose to install as a windows service. I guess in your case the issue is the port no already in use by another program. Look into the server.xml file in CATALINA_HOME/conf directory and change the default port no in the connector tag to something other than 8080...

<Connector port="8080" protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="8443" />


Modify 8080 to some unused port..

hey, it's working when i startup as root. i didn't do anything for that. anyway thanx
