GWT Development Mode error

Question

When i try to execute the project, even the default "Web Application Project", I receive this error:

INFO: Module instance default is running at localhost:8888 apr 07, 2014 9:02:46 AM com.google.appengine.tools.development.AbstractModule startup INFO: The admin console is running at localhost:8888/_ah/admin apr 07, 2014 11:02:46 AM com.google.appengine.tools.development.DevAppServerImpl doStart INFO: Dev App Server is now running Exception in thread "Code server listener" java.lang.IllegalArgumentException: invalid host wildcard specification at java.net.SocketPermission.init(Unknown Source) at java.net.SocketPermission.(Unknown Source) at java.lang.SecurityManager.checkConnect(Unknown Source) at java.net.InetAddress.getHostFromNameService(Unknown Source) at java.net.InetAddress.getCanonicalHostName(Unknown Source) at com.google.gwt.dev.shell.BrowserListener$1.run(BrowserListener.java:78)

How can i resolve this error? Thanks.

Answer 1

Do you get this error after first successful run? if yes then stop already running server instance and then restart the server.
