Tomcat stopped

Even i killed running java id using kill -9 PID but still i am getting same error and i can not start my application.

How to fix this and shutdown my tomcat without bug ?

I think the thing is not about stopping server, but about starting server ,you should post the error message when you start the server(there should be some) . — 柯鴻儀

If its windows try below to kill the running tomcat process

C:\Users\Saravana.Saravana-PC>netstat -ano  | find ":8080"
  TCP    0.0.0.0:8080           0.0.0.0:0              LISTENING       1448
  TCP    127.0.0.1:8080         127.0.0.1:49543        ESTABLISHED     1448
  TCP    127.0.0.1:49543        127.0.0.1:8080         ESTABLISHED     4068
  TCP    [::]:8080              [::]:0                 LISTENING       1448
  TCP    [::1]:8080             [::1]:49542            ESTABLISHED     1448
  TCP    [::1]:49542            [::1]:8080             ESTABLISHED     4068

C:\Users\Saravana.Saravana-PC>taskkill.exe /PID 1448 /F
SUCCESS: The process with PID 1448 has been terminated.

C:\Users\Saravana.Saravana-PC>

In Linux if stopTomcat.sh is not stopping tomcat then

ps -ef | grep "tomcat"
kill -9  <PID>

kill the running instance of tomcat, killing your java application wont kill tomcat

To get the running tomcat port use sudo netstat -lnp | grep <PID>

I am using linux so i used ps -ef | grep "tomcat" and killed the corresponded running PID and again i started tomcat and shutdown tomcat but same issue rising :(

Saravana Over a year ago

did you check the logs? what exception are you getting?

MMMMS Over a year ago

It shows java.net.BindException: Address already in use <null>:8105

Saravana Over a year ago

are you running any other service on port 8105? it looks like some other process is already using this port. grepsudo netstat -lnp with the port, it'll show the process using the port, kill the process and try

I checked using netstat -lnp 8105 but i dont find the 8105 is listening

I cleaned my webapps and it helped me:

cd /opt/tomcat/webapps
shopt -s extglob
rm -rf !(ROOT|balancer|webdav)

after that, I was able to deploy my application

Try changing the port number from 8005 to some other port number and restart Eclipse .

sometimes it may happen that the port number is blocked by sudden termination of process
