  • enter to directory with project
  • run: mvn clean install && java -jar target/videochat.war

Enter key password for <tomcat>
  (RETURN if same as keystore password): <RETURN>

then:

  • run: mvn clean install && java -jar target/videochat.war
  • enter https://localhost:8443 in your favourite browser (HTTPS is important, because default http handler isn't configured)
  • accept untrusted certificate

Sometimes websocket (js side) is throwing exception then try to change localhost to 127.0.0.1
