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

Error Message when I run it

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?

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

https://github.com/gwt-plugins/gwt-eclipse-plugin

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

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.

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.
