I have installed tomcat 6 in my PC wiht port 8080 at locahostand using eclipse ide for running a servlet.

the problem is when i run a servlet from eclipse it show error like this :
Server ports(8080, 8085 ,8009) required by Tomact v6.0 Server at localhost already in use. Server may be running on another process or system process may be using port.


I have make sure that my system(windows -xp) is not running Tomact Server as its service.

Even though i have changed port of tomact inside eclipse setting from (8005, 8080, 8009) to (9005, 9080, 9009) still not working.

how do i rectify that?

Is that Tomca server bundled within eclipse? Or it is a separate installation and later added into eclipse via some plugin.?
Where did you try changing ports? you can change them inside xml files of Tomca installation itself, i suppose it is server.xml
If it is already in use then you can see in browser if something appears at http://localhost:port_number

And what appears at http://localhost:9080? after starting the server?

Congrats, it looks your tomcat is up.!

Try http://localhost/manager/list or http://localhost:9080/manager/list

If it asks for username password then i think you may have to configure them in tomcat-users.xml available in Tomact inst directory.

You can uninstall any program on xp from control panel. If you see it in add/remove programs then go ahead.
You can then download zip and install Tomcat(not as windows-service but rather a single folder).
What plug-in are you using currently, i think there is one called sysdeo. You can google it.
Plugin will not have Tomcat, you will have to first install tomcat and then use-plugin (probably copy-paste plugin files into some folders of eclipse inst directory) to connect tomcat with eclipse.
Restart eclipse(close and re-open after plugin-installation)
Now you should see stop-start icons of tomcat inside eclipse itself.
This should do.

Installing plugin enables you to start-stop-deploy-undeploy wars to tomcat from within the eclipse, however you are still free to use eclipse for development alone and manage deployments outside of it.

If you have time, I would suggest you still play around with your old installation before you think of uninstall-reinstall, you may have a learning experience.


Missed it, after successful installation of plugin you may to configure it to point to Tomcat installation directory.

Hello Akhilesh,

thanks for the replies.

I was also facing the same problem as Naveen mentioned in the very starting of the thread.

I searched on google and found the page on tomcat site "http://tomcat.apache.org/tomcat-6.0-doc/windows-service-howto.html".
which gave me idea to stop the running tomcat server (as WinNT Service) from Windows Services console (To Open it, Go to 'Run' > type 'Services.msc' and hit enter).

I stopped the Apache Tomcat Service from there and made its startup type as 'Manual' to avoid already started service every time I start the system.

After stopping the 'Apache Tomcat Service', Now i am able to start the Tomcat Server from Eclipse IDE.

Hope this would help.

Thanks Everyone..
