在Eclipse中运行时发生GWT错误

Question

When i'm trying to run gwt through eclipsc it showing the error like,

**

Could not open the requested socket: Address already in use Try overriding --address and/or --port.

**

Answer 1

An error like that means there is already a process running on that port, it might have crashed and may be dead thus it does not show up in your browser when you search it. You need to stop that process, here are several commands

if you are running linux then run several lines in your console

get all applications running on port [need their pid]

sudo lsof -w -n -i tcp:8888

kill applications running on port

sudo kill -9 pidnumber

If windows then just:

Find the pid for the dead process that particular port

netstat -a -o -n

to kill the process

taskkill /F /PID <pid>
