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


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?


Solution

  • 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.
