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 ?

Answer 1

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> sudo netstat -lnp | grep <PID>

Answer 2

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

Answer 3

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
