问题
I am using Intellij Ultimate edition 14.0.2
Working on a Java project using Maven as my build tool.
We are getting this error when attempting to launch my project via Tomcat server.
Application Server was not connected before run configuration stop, reason: Unable to ping server at localhost:1099
Have attempted, mvn clean install, rebuild the project in intellij, open and shut down intellij.

Thanks for the feedback everyone. I ended up editing my host file to reference my computer name. I have not been able to recreate the issue.
Solved for now.

Your problem is rarely ambiguous. You should check connection between IntelliJ IDEA and Tomcat Server. Checklist like marked points:
+ Configure Tomcat Server.
+ Before launch application server, you must configure to add artifacts to application sever.
+ Turn off other Tomcat server(s) in your computer (localhost)
etc.
