One of the ways is to have the GWT debugger spin up an instance of jetty and have your web application deployed in it. Then have it launch a browser with the appropriate url in it. Adding the --gwt.noserver on the command line tells GWT you don't want to spin up the jetty server, that the application you are working with is somewhere else and you will manually go to it. > Or this: > > Q: Client-side logs are not persisted on Engine, e.g. > $JBOSS_HOME/standalone/log/engine/engine-ui.log. A: Currently, client-side > logs are enabled only when debugging the application via Development Mode. > When the application is running normally it is all just javascript running in the browser. There are 'log' statements in the code but no loggers to write the data to. When you are connected to the browser with the GWT debugger the GWT debugger provides a logger to write to.
