Error With Port 8080 already in use

Question

Can anyone help me to solve the following case    I am trying to generate my first web site using java and working with Eclipse Galileo running on Ubuntu 9 10  Since I generate my first lines of code I haven t seen the web  All the time when I try to run the program I get the following error   Several ports  8080  8080  required by Tomcat v6 0 Server at localhost are already in use  The server may already be running in another process  or a system process may be using the port  To start this server you will need to stop the other process or change the port number s    I have read a lot about the way to change the ports for my tomcat  pass from the 8080 to 80  but it has been impossible  I read some forums where the way to solve this problem is going to the file that contents the server number for tomcat  which is a XML file  but when I open the folder there is not a xml file with the name   I already explored the port using sudo lsof -n -P -i    start and shut-down tomcat but the mistake is still there   What can I do   Thanks a lot

You ve another instance of Tomcat already running  You can confirm this by going to http   localhost 8080 in your webbrowser and check if you get the Tomcat default home page or a Tomcat-specific 404 error page  Both are equally valid evidence that Tomcat runs fine  if it didn t  then you would have gotten a browser specific HTTP connection timeout error message   You need to shutdown it  Go to  bin subfolder of the Tomcat installation folder and execute the shutdown bat  Windows  or shutdown sh  Unix  script    check this answer for more information

The solution to this issue is   Step 1  Stop Tomcat By service or by  bat  sh what ever the case may be     Step 2  Delete the already configured Apache Tomcat on eclipse   Step 3  Now reconfigure the apache on the eclipse and start the server using UI as provided by eclipse   I have the same issue and it has worked

In your apache conf folder  open the httpd file and look for 8080 port  Change 8080 to any port you like  I believe you will find 8080 on two places  Restart your server to see changes

It has been long time  but I faced the same Issue  and solved it as follow  1  tried shutting down the application server using the shutdown bat  bash which might be in your application Server   bin shutdown     My Issue  was that more than 1 instance of java was running  I was changing ports  and not looking back  so it kept running  other java processes  with that specific port  for windows users    ALT Shift Esc  and end java processes that you are not using and now you should be able to re-use your port 8080

This Worked for me   In Eclipse NEON double clicked on Server tab which redirects server overview window  Here you can change port number based on your requirement for Tomcat Admin and HTTP port   And restarted the server   Hope this helps you
