In GWT 2.2, JClassType (everything in com.google.gwt.core.ext.typeinfo actually) was changed from an interface to an abstract class (that was almost 6 years ago already, and I can't find where it was announced; and release notes for such ancient versions have been lost)

You need to update GXT (and all your other dependencies) to a version that's compatible with GWT 2.7. 

[Majdi ABDELMOULA]

Thank you for your reponse. 

the problem GXT is not free now. I will lost two old projects (projects since 6 years). I will use smart GWT for a new project, so i must start from zero, but i worry that Smart GWT will be not free in the future too. 

The only solution for resolving these errors , is to Buy GXT plugin from the sencha website ??

gxt 2.3.1a-gwt22 (https://search.maven.org/#artifactdetails%7Ccom.extjs%7Cgxt%7C2.3.1a-gwt22%7Cjar) might work with 2.7: https://plus.google.com/106079938918640446800/posts/iAL9m39jFxt 

[Majdi ABDELMOULA]

Thank you Thomas , you save me, I can run the project without erros now :) Can i use this version of GXT jar's for commercial project or i must pay for that ?? its licence is it GPL ??

:)))) 

[David Becker]

GXT is available under both a commercial and GPL license. Details can be found here: https://www.sencha.com/legal/#Sencha_GXT

[Majdi ABDELMOULA]

Thanks David for the link, it is clear now
