Port 8080 already in use in eclipse - spring

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.
Best Regards,

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 .

Tomcat Debug Error: Unable to open debugger port (127.0.0.1:63199): java.net.BindException "Address already in use: NET_Bind"

I woke up for work and started receiving this error, but I can't find this specific error anywhere.
I tried using netstat -ano to find any instances running on the aformentioned port, and also the ports I run Tomcat on:
HTTP port: 8090
JMX port: 1099
But no processes are running on any of the three ports. Any ideas?

Oh,my! This helps me a lot
// first,close your idea
// then, run cmd as administator
net stop winnat
net start winnat
// launch your idea
Before,I have tried this,but it doesn't work
ipconfig /flushdns
netsh winsock reset

As for me,the problem begin when i use idea to debug my web application.
Then i find where the port configured and change to another port.

this link might be helpful
net stop winnat
launch your idea tomcat
net start winnat

Windows 10 Kill EDB Postgres 8080 server

I want to kill and remove the software that uses the 8080 port that EDB Postgres localhost server so I can use the port for Jenkins.
Using tasklist it tells me the port which is processing, fine for kill the process, but where can I delete uninstall the software.

Just find the server named "PEM HTTPD" and turn it off.Also you can change its start mode to manual.

tasklist is good but you can also use netstat -ano to find the port if you didn't find the process but in taskmanager in windows 10 there is a services tab with a PID column. Just click the column and find the PID. Then right click it and hit properties to find the path of the software. Kill the process and remove the software. Restart and see if it works.

Tomcat is misconfigured for local IP

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

"Address already in use: bind" when running Spring Boot application

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.

How can I determine which port my GlassFish server is running on?

I have started a GlassFish server on my machine.
How can I determine which port the GlassFish server is running on?
I have tested both 8080 and 4848 ports.

You can try this, it may help
asadmin get server | grep listener
http://blogs.oracle.com/openroad/entry/changing_default_glassfish_port_numbers
For windows this may help (from the comments of the link)
<GLASSFISH_PATH>\\bin>asadmin.bat --port 15050 get server.network-config.network-listeners.network-listener.\*
Or you can look at the ports from configuration files (in the file search for: ):
<GLASSFISH_PATH>\\glassfish\\domains\\domain1\\config\\domain.xml
