GWT：我可以在浏览器中调用servlet。当我通过formpanel调用它时，它可以调用onSubmit。但它不会调用 onSubmitComplete。它还会弹出一个新窗口，uri 是我的 servlet。

String URL= GWT.getModuleBaseURL()+"getType";
         FormPanel formPanel = new FormPanel();  
         formPanel.setAction(URL); 
         formPanel.setEncoding(FormPanel.ENCODING_URLENCODED);  
         formPanel.setMethod(FormPanel.METHOD_GET); 

     formPanel.addSubmitHandler(new SubmitHandler(){

        @Override
        public void onSubmit(SubmitEvent event) {
            // TODO Auto-generated method stub
            System.out.println(event.getSource());
        }

     });
     formPanel.addSubmitCompleteHandler(new FormPanel.SubmitCompleteHandler() {  
            public void onSubmitComplete(SubmitCompleteEvent event) { 
                System.out.println("in");
                System.out.println(event.getResults());  
            }  
        });  
     formPanel.submit();

GWT.xml
 <servlet class="msp2.server.getType" path="/getType" />  


web.xml
    <servlet >
<servlet-name>getType</servlet-name>
    <servlet-class>msp2.server.getType</servlet-class>
</servlet>

<servlet-mapping>
    <servlet-name>getType</servlet-name>
    <url-pattern>/msp2_app/getType</url-pattern>
</servlet-mapping>
