GetServletContext() not working when i add spring4gwt to a gwt project

[Otis Onesh]

If i add spring4gwt in the starter gwt app i get the exception below, problem being at code

public String greetServer(String input) throws IllegalArgumentException {
		// Verify that the input is valid. 
		if (!FieldVerifier.isValidName(input)) {
			// If the input is not valid, throw an IllegalArgumentException back to
			// the client.
			throw new IllegalArgumentException(Name must be at least 4 characters long");
		}
	
	
		String serverInfo =[b] getServletContext()[/b].getServerInfo(); // GET ServletContext() IS NOT INITIALIZED? WELL WHY IS  IT NOT? IT WORKED BEFORE WITH THE STARTER APP
		
String userAgent = getThreadLocalRequest().getHeader("User-Agent");

		// Escape data from the client to avoid cross-site script vulnerabilities.
		input = escapeHtml(input);
		userAgent = escapeHtml(userAgent);
