I have a project on Spring with maven build. (Eclipse IDE on Windows). When I run my Spring Boot application I am getting this error
***************************
APPLICATION FAILED TO START
***************************
Description:
The Tomcat connector configured to listen on port 8080 failed to start. The port may already be in use or the connector may be misconfigured.
Action:
Verify the connector's configuration, identify and stop any process that's listening on port 8080, or configure this application to listen on another port.
I have tried to listen to another port (using application.properties file) but the error still persists.
I have also tried command line to kill my process using these two lines.
// Step 1
netstat -ano | findstr :yourPortNumber
//Step 2
taskkill /PID typeyourPIDhere /F
I think my tomcat is misconfigured for the project. Weirdly, it seems to work on another project but on this one. How can that be possible? Thanks for the help in advance.
EDIT:
I am sorry but I forgot to mention that I wanted to run Tomacat on my PC's IP. It is working fine for localhost.
Here is my application.properties file:
spring.http.multipart.enabled=false
server.address=172.27.86.141
server.port=8080

Sample Spring boot application is created and build on Jenkins.
For Deployment of war file in tomcat server ,
I am facing a several issues.
Error :
Credentials At Jenkins :
tomcat-users.xml File :
Still I am facing the same issue. I had searched in google and stackoverflow but still i can't found the correct answer.
Can Any one help me in this ?
Your error message is a connection refused: connect exception. You should check the following:
Your Tomcat server is up and running on port 8082 at the same server where your jenkins server is running (localhost). To make sure, run: telnet localhost 8082 from the same server commandLine ( I see you are in windows). If it connects then your Tomcat server is OK.
Check if the manager application of Tomcat is deployed. Try to load the following web page and check if exists: http://localhost(or hostname of server):8082/manager/html
Try to disable the windows firewall and any other firewall you may have (or antivirus firewall) and check if it prevents jenkins to connect to Tomcat (again check with telnet command)
Description:
The Tomcat connector configured to listen on port 9009 failed to start. The port may already be in use or the connector may be misconfigured.
Action:
Verify the connector's configuration, identify and stop any process that's listening on port 9009, or configure this application to listen on another port.
I get an error of this kind, but I have not changed the port, what should I do in this case?
I can throw application.properties
First, if you would like to check application running on that port please either do netstat command or resmon.exe and if application is user then exit it.
Or start appliation with new port number
I am trying to run a Spring MVC demo file on Eclipse oxygen when I hit the button run as> run on server it shows the following error after a moment
Port 8080 required by Tomcat v8.5 Server at localhost is 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)
Step 1: (open the CMD command)
C:\Users\username>netstat -o -n -a | findstr 0.0:8080
TCP 0.0.0.0:3000 0.0.0.0:0 LISTENING 3116
Now , we can see that LISTENING port is 3116 for 8080 ,
We need to kill 3116 now
Step 2:-
C:\Users\username>taskkill /F /PID 3116
Step 3: Go to Eclipse and start Server , it will run
OR
you can change port number in folder servers>Tomcat>server.xml
A process is already listening on port 8080 and you can't have more than one process listening on the same port.
You have two options :
Kill the existing process if it's not usefull
netstat -tulpn | grep :8080
Change you application port. In your application.properties and file add this line server.port=8081
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
please kill the java process from task manager if windows, else if linux system kill -9 tomcat
You can just change the default port of your Tomcat server if the problem persists.
Always Kill the process before deploying your war file in tomcat
ps -A|grep tomcat It will list all tomcat process. Note Down the PID and run
KILL <PID>
Cross check by ps -A|grep tomcat
I face the same problem and after searching the answer as shown below:
1. open Monitor Tomcat as shown below:
Simply press stop as shown in below picture:
Finally it works with me after many trials and suggested solutions.

My method is to run tomcat7w.exe to disable it. (Only Stopping it is not enough). And my Kaspersky (Anti virus) generate some new rules for eclipse and java.
Followed below steps and was able to solve the issue:
C:\Users\Sri Priya P Kulkarni>netstat -o -n -a | findstr 0.0:8080
TCP 0.0.0.0:8080 0.0.0.0:0 LISTENING 13196
C:\Users\Sri Priya P Kulkarni>taskkill /F /PID 13196
SUCCESS: The process with PID 13196 has been terminated.
you can go in servers > server.xml.in server.xml file u should changes like,
step 1)
step 2)
step 3) <Connector port="8010" protocol="AJP/1.3" redirectPort="8443"/> and save the changes .
I have a problem with running my sample Spring Boot Application.
When I try to run it, this error occurs:

Is it ok the first time you run it, and run it again you get an error?
If this is the case, You need to stop service before running again.
Here is a way to stop.
Click the stop button that looks like this:
"Address already in use" means, there is already another application running on port 8080. Use your OS tools to find that process and end it, before you start your application, or let your application run on another port. If you use an embedded server in your Boot application, you can specify the following property:
server.port=8085
Of course you can choose whatever port you want.
I have a very simple solution:
As the answer above stated, when you start Spring Boot app, the PID of underneath server(Tomcat or Undertow, or whatever) will be shown in the console; you may start again the app without terminating the former one, especially when you are in debug mode, thus the error. This applies to Intellij, too.
But, if you have started again, the PID is no longer available for you because previous session output is cleared.
So, if you are using Eclipse, just close it, and open Task Manager to terminate other java.exe JVM process. Be sure that you have no other JVM-based services running which cannot be stopped. (Like Kafka server, Apache Storm, etc.)
The Tomcat instance is one of them.
Log shows that server is already started on port 8080. I faced the same problem. go to windows task manager and end process that is javaw.exe, it worked on my application.
Two possibilities
P1.Another Application is using port 8080
Solution:-
a.Stop that application and free port 8080 for your application.
b.Change your application server port, for that create a file named
application.properties in resource folder and add property
server.port = 8085
(8085 can be replaced by any port number of your choice which will not conflict with other
application server ports)
location of application.properties file
snippet of application.properties file
P2. Your application is already running
Solution
a. Pretty simple solution for this situation is stop your currently
running application and rerun it
b.If you want to run multiple instances of your application then keep
current application running change server port as explained above and
run the application the new instance will run of another port.
Even I faced this issue u can just stop the application(there is a stop button on the top toolbar) and restart again it worked for me and I used STS
In the Eclipse situation, check if there are items running in the window "Progress"(Windows > Show View > Progress)
Stop the running process, which might be locking your desired port.
Got the same error.
The springboot application has inbuilt tomcat server which runs on port 8080..if you have any other process currently running on port 8080,The java.net.BindException will raise..so kill the processes which are using 8080 thorugh cmd as follows:
-->
open command prompt as Administrator.
--> netstat -ano | findstr :<PORT>
netstat -ano | findstr :8080
TCP 0.0.0.0:8080 0.0.0.0:0 LISTENING 10568
TCP [::]:8080 [::]:0 LISTENING 10568
-->taskkill /PID <PID> /F
taskkill /PID 10568 /F
Now if you want recheck your running process by using netstat -ano | findstr :8080 command..
and again restart or rerun our application..
This is for first ever time you wanted to run springboot application.
Hope this might be helpfull,worked for me :)
Second case:
In the first time you run ok right? and run again it got an error? If right, You need stop service before run again..if it is the case follow #Sang9xpro
answer above.
Seems your server is already up. If you are using linux based system, type following command in terminal to check which port is active on your system.
"ps -ef | grep 8080"(or whatever port is mentioned)
Now you need to kill this one if you wish to run the server on same port.
kill -9 8080
Voilla!! Try booting your application once again and it will work.
Extra:
You'll come to me complaining an important application is already listening on mentioned port(8080) and you do not want to kill it. No probs.
Create an application.properties file inside your resource folder and change port to whatever you like.
server.port = 8081
Voilla!! You did it!! :)
Let me know if further clarifications required.
This is because you have run the spring boot application once in your eclipse IDE and closed the application and you assume that the embedded server is stopped. But it is not the case. Even after you closed your application in Eclipse -> Console window, embedded tomcat server is running. What you can do is, run your spring boot application again and look at the console messages. Immediately after Spring Logo, you can find Starting on with PID 16676. This is the PID you need to search in "Wndows Task Manager -> Processes -> PID". Select that process and "End Task". Now if you start your spring boot application, it will start without issues.
I have been using Tomcat integrated with Eclipse for a long time, and now I want to try Jetty with maven without Eclipse (I am not using m2Eclipse for now). I know Jetty is using tomcat as container, and port will still be default 8080. Before doing anything reckless and screw up my setting, I would like to know that if any conflict could arise, and things to watch out for. If I just put jetty-plugin to the pom.xml in a separate project, will that affect my other projects build on tomcat with Eclipse?
Thank you.
If you want to run jetty and you already have tomcat running on port 8080 then that will not work, only one or the other can use a single port. The solution is simple though, either set a different port in the jetty-maven-plugin configuration (8090?) or set no port and in the output of the plugin running it will have a line about the SelectChannelConnector or ServerConnector starting on port ###. Simply use that in your browser for the port.
[edit] I'll also note that should you have tomcat running on 8080 and you startup jetty and it tries to use 8080, the jetty process will fail and the tomcat process will be completely unaffected. The same as if the roles we reversed.
