Добрый день.
Пытаюсь сделать первую программы на Java для Web.
В NetBeans 7.4 создал проект Веб-приложение. + добавил платформу GWT и Hibernate
Подправил/добавил файлы, но проект не компилируется.

GWT Compiling client-side code.
Compiling module org.yournamehere.Main
Finding entry point classes
[ERROR] Unable to find type 'org.yournamehere.client.MainEntryPoint'
[ERROR] Hint: Previous compiler errors may have made this type unavailable
[ERROR] Hint: Check the inheritance chain from your module; it may not be inheriting a required module or a module may not be adding its source path entries properly
C:\Users\ivan\Documents\NetBeansProjects\HelloWeb\nbproject\build-gwt.xml:331: The following error occurred while executing this line:
C:\Users\ivan\Documents\NetBeansProjects\HelloWeb\nbproject\build-gwt.xml:480: Java returned: 1
В чем может быть проблема?
