Il semble que ton
Code:

1 2 3 4 5  <servlet-mapping> <servlet-name>employeeService</servlet-name> <url-pattern>employeeService</url-pattern> </servlet-mapping>
ne soit pas bon.

En GWT 2.x l'url pattern est de la forme /le-nom-de-ton-appli/le-nom-de-la-servlet

Avec "le-nom-de-ton-appli" la valeur de l’attribut rename-to dans le fichier tonprojet.gwt.xml dans la balise module

Je confirme ce que dis Galel.

Remarques :

Depuis que GWT a introduit l'annotation @RemoteServiceRelativePath
Tu peux directement faire :
private static final EmployeeServiceAsync service = GWT.create(EmployeeService.class);

Ton annotation @Service, c'est pour Spring ?

Je penses que tu dois vérifier tes fichiers de conf spring et surtout:

			expression="org.springframework.stereotype.Service" />
 
<!-- pour les @Controller-->
