 | <p>GWT modules may declare one or more <code><servlet></code> | 
 | tags. These define Java Servlets that implement the server-side | 
 | component of a GWT-enabled web application.</p> | 
 |  | 
 | <p>Prior to GWT 1.6, these GWT module servlet tags controlled the set of | 
 | servlets were actually instantiated during hosted mode. But as of GWT 1.6, this | 
 | is no longer true.  Instead, the web application's <code>WEB-INF/web.xml</code> | 
 | configuration file controls what servlets are instantiated. A GWT module | 
 | specifies only what servlets are <i>expected</i>. | 
 |  | 
 | <p>During hosted mode startup, the set of expected servlets (from GWT module | 
 | <code><servlet></code> tags) is validated against the set of actual | 
 | servlets (from the <code>WEB-INF/web.xml</code>) and a warning is issued for | 
 | each expected servlet which does not match an actual servlet. |
