Tomcat Error [message #1819001]

Hi there,

I have Tomcat 9 running on localhost:8080. It shows the tomcat default page on the browser, which means it's up and running.

I also have the tomcat port configured as 8080 in the eclipse properties

(See attached screenshots)

When I run the application, i get the following error:

"The server cannot be started because one or more of the ports are invalid. Open the server editor and correct the invalid ports."

Any clues on how to fix this?

thanks in advance
Bruno

You should probably ask this to another forum, like https://www.eclipse.org/forums/index.php/f/251/ or https://www.eclipse.org/forums/index.php/f/88/

Running Tomcat or a web-app from Eclipse is done by launching a new instance of Tomcat, configured the way you've set it up in the Servers view. The message you're seeing is correct, as both your installed and launched instance can not both listen on the same port at the same time. You'll have to change one of them.
