When you start Tomcat server, port 1099 appears to be another process is using
the solution:

　　1, the process to find the occupied port 1099, enter the command windows to see what process is using port 1099, use the command: netstat -aon | findstr 1099 1099 to find the occupied port of process
　　
　　 2, then close the occupation of the port process: taskkill - f -pid 3756

Error running 'Tomcat ***': Unable to open debugger port (127.0.0.1:36889): java.net.SocketExcept

Error found idea to start the project: Address localhost: 1099 is already in use

Debug报错：Unable to open debugger port (127.0.0.1:36889): java.net.SocketExcept

See the port occupied, subconsciously to modify the port, but no matter what the modified, is still being given port is in use, and to see the error port is not in use, online solution, mostly to see the port being used by which processes, then check out kill -9, or directly modify the port. But that does not work wow not work!

Then I went to the tomcat folder, use ./startup.sh start tomcat, really successful start, but the browser to access localhost: 8080 did not visit! I have deepened my doubts!

Then download a new version of tomcat, the idea of re-allocation tomcat again, or not! ! !

Then inadvertently I thought host, went looked, found no 127.0.0.1 localhost how this line?

So in SwitchHosts configured separately in this line, ok then start the project, the problem is solved! ! !

idea tomcat热部署 Error running 'Tomcat 7': Unable to open debugger port (127.0.0.1:3622): java.net.SocketExcepti

After testing, found that only need to modify the http port 8081 can, JMX port do not change default is 1099

In today into the tomcat debug mode Times this anomaly, tomcat failed to enter debug mode

Online search the next reason, I found that by modifying the following two ports can be normal access to the tomcat debug mode

If that does not solve the problem, then you only need to open the Task Manager, all the java virtual machine process to end off

It can normally turn on the server
