 	The solution therefore is quite simple: to remove the newer 1.3 version of the API, from the class path, and replace 
 	it with the version supported by your application server.

+* WSDL
+
+** How do I retrieve the WSDL from a Service? The ?WSDL query parameter does not work.
+
+	The ?WSDL is a way to get a WSDL of a class. In SWS, a service is generally not implemented as a single class, but 
+	as a collection of endpoints.
+	
+	There are two ways to expose a WSDL:
+	
+	* Simply add the WSDL to the root of the WAR, and the file is served normally. This has the disadvantage that the
+	"location" attribute in the WSDL is static, i.e. it does not necessarily reflect the host name of the server. That's
+	why in the airline sample airline-servlet.xml, we define an WsdlDefinitionHandlerAdapterthere, which transforms the
+	location.
+	
+	* Use the MessageDispatcherServlet, which is done is the echo sample. Every WsdlDefinition listed in the
+	*-servlet.xml will be exposed under the bean name. So if you define a WsdlDefinition named <<<echo>>>, it will be
+	exposed as <<<echo.wsdl>>>. (i.e. <<<http://localhost:8080/echo/echo.wsdl>>>).
