I Also have an issue with Validation.jar file. I can't build my application with GWT 2.4. but I can build the same application with GWT 2.0. Here is list of software I use. GWT 2.4 Spring 2.5.4 Hibernate 3.7 This is my 'workaround'. I remove the validation-api-1.0.0.GA.jar from my eclipse plugin directory. (C:\MyProgram\eclipse\plugins\com.google.gwt.eclipse.sdkbundle_2.4.0.r36v201108301710\gwt-2.4.0). Then I can build my application. I need better 'working' solution of it.
