Hi everyone,

I just did a fresh installation of Jakarta 4.0.3 and Jakarta 4.0.4 and when i try to start Tomcat, i get the same message on both version, which is:

Thank you in advance,

It looks like there is already an application running that has bound port 8080. Is this a shared machine? If so, someone may already be running tomcat on this port. Try changing the port to 8081 or something like that and try restarting.

Hi meadandle,

Thank you for your response.

I am runnig Tomcat on a test machine and it is a stadalone installation.

Also, I did not modify anything in the connfiguration files.

As you can see in my test, the &quot;netstat -a&quot; did not produce anything. I also used the &quot;lsof&quot; program to verify if there was something on port 8080 and on port 8007. Nothing was reported.

Any other ideas?

Thank you

Hi,

I finally found the culprit on my problem. On AIX, when we install the HTTPServer application from IBM, this one have the &quot;admin&quot; section which listen on port 8008 by default. Also, we had to change the default Web Server port from 80 to 8009 because we are using a different Web Server program.


- How I solve this problem

1_ I looked at all the ports used in the configurations files.

2_ I issue the this command: netstat -na | grep -i listen

3_ I found that port 8009 was used

4_ I changed the port for the HTTP Server and everything work fine.

I am on the next step now,

Thank you
