I am debugging a GWT application and I need to print some stuff to the console for testing purposes. System.out.println and GWT.log don\'t work. Do
I had this problem as well. The GWT log works but because it's all converted to javascript, it prints to the client output, so just view your browser's console and they will be there. In Google Chrome click the triple-line Customize button in the top right, click Tools-->Developer tools and the console will pop up. Your sought-after statements will be there. Also, Ctrl+Shift+I is the shortcut that brings it up. If you want to print to the server, I believe logger handlers and such are in order?
