How to switch to SuperDevMode from DevMode in GWT running through Eclipse

Question

I am learning GWT for my internship that I start next week and I keep getting this error:

I installed the GWT plugin and related engine through Eclipse Mars. I am using the default code generated when you create a new project in Eclipse. I also tried running the code of a tutorial from the GWT website and it generates the same error. Other posts mention removing <add-linker name="xsiframe"/> in the XML file but that just generates another error I cannot solve.

Is this caused by an error in my code or by how I set the project up?

Answer 1

Go to Project -> Properties, find Run/Debug Settings, select your launch configuration and hit Edit... button. Go to GWT tab and change Classic Development Mode to Super Development Mode.

Answer 2

This is the old Dev Mode.

Today the Super Dev Mode is used for GWT developement. There are a lot resources on the web.

This one f.e.:

Sencha GXT Documentation Super Dev Mode

or

GWT Tutorial for Beginners

Search for questions about SDM here at StackOverflow. You will find a lot.

Answer 3

Don't use the plugin from Google but the new one from Brandon.

He has a bunch of YouTube videos that display how to set up this plugin: https://www.youtube.com/watch?v=DU7ZQVLR5Zo&list=PLBbgqtDgdc_TqzA-qXrjgTFMC_6DKAQyT
