Tomcat connector in failed state what could be wrong? please help me :C

I hope you looked through Stack Overflow solutions: http://stackoverflow.com/questions/20735205/launching-spring-application-address-already-in-use

Take a look at this one. I remember having the same problem.

1. First of all make sure you are not re-running the boot run twice. ( With Spring you have to kill old one first, then wait, then restart. Chris is doing that in all 'Spring' courses.

2. If you are still running only one app, try to kill ports with application directly: (For linux/mac that will work: lsof -i :8080 | grep LISTEN and then kill -9) see the post above how to do that. I suggest this way: you have to figure out which application is using port 8080, and kill it. Using other port is temporary solution. I don't have Windows, take a look, how to see which ports are which with this article: http://www.howtogeek.com/howto/28609/how-can-i-tell-what-is-listening-on-a-tcpip-port-in-windows/

When you find which app is using 8080, kill it and rerun without -Dserver.port option.

I cannot say more, because you show only one line of code to me, so If you really want for someone to take a look: Share your project on GitHub. So that anyone and I can take a look. If you are using IntellijIdea, it is really simple: https://www.jetbrains.com/help/idea/2016.2/share-project-on-github-dialog.html ( Ctrl-Shift-A and then I type 'Share' and pick 'Share Project on Github')

Yup that was the page i was looking i tried to use -Dserver.port=8181 following this http://codedevstuff.blogspot.com/2015/05/change-port-on-spring-boot-application.html as well.

sorry for that one line of code that i showed you here's the project i uploaded on github https://github.com/Lestah/giflib thanks Alexander

I tried to run your App from GitHub. It works just fine. Which means you have problems with your machine, and port, not the java code/spring application itself.

Did you try to localize which program is using port 8080 and kill it, using the article above?

http://www.howtogeek.com/howto/28609/how-can-i-tell-what-is-listening-on-a-tcpip-port-in-windows/

Should be pretty straightforward, typing

• netstat -aon : should show you ports and PIDs of appications that are using them
• then you can kill the app that is using port 8080

I tried that on my desktop-pc it runs with no errors but i want it on my laptop to work. I've red the links you send to me about killing the application who uses port 8080

here's what I've found executing the netstat -aon

TCP 0.0.0.0:8080 0.0.0.0:0 LISTENING 4

that number 4 is the PID who uses my port 8080

so on task manager processes details tab

Name PID Status User name CPU Memory (private working set) Description System and compressed memory 4 Running SYSTEM 00 282,264 K NT Kernel & System

so on the task manager services tab i look for the pid number 4 i cant find that number 4 PID to stop it

Hey Buddy Thanks a lot for helping me on this and thanks to that last link u send to me gave me an idea to change it programmatically it runs now on my laptop free of errors hahaha can i add you as friend here on treehouse?
