如何以编程方式在AEM中创建用户和密码？

Question

我需要以编程方式在AEM中创建用户和他的密码。我在AEM中创建了一个HTML页面，当我们点击该按钮时我有一个SUBMIT按钮我想运行我在Eclips中运行的servlet代码。     *用户创建程序应该在Servlet中

My HTML CODE INSIDE CRXDE Lite:-
-------------------------------

<form method="get" action="/bin/userCreationupdateservlet/get" enctype="multipart/form-data">
</br>
</br>
   <h2>User Creation</h2>

  <input type="submit" name="submit" value="Submit" class="submit">
</form>

我的Servlet代码内部Eclips

@Component(immediate = true, metatype = true, label = "userCreationupdateservlet")
    @Service(Servlet.class)
    @Properties(value = {
            @Property(name = "sling.servlet.paths", value = "/bin/userCreationupdateservlet/get"),
            @Property(name = "sling.servlet.methods", value = "GET") })
    public class userCreation extends SlingAllMethodsServlet {

                private static final long serialVersionUID = -4364646607782417077L;

                private static final Logger log = LoggerFactory.getLogger(userCreation.class);

                @Reference
                private CreateAEMUser semUser;

                @Override
                protected void doGet(SlingHttpServletRequest request,
                        SlingHttpServletResponse response) throws ServletException,
                        IOException {
                        log.info("Hi this Servlet :::::::");
                      final boolean isMultipart = org.apache.commons.fileupload.servlet.ServletFileUpload.isMultipartContent(request);
                         PrintWriter out = null;
                         log.info("Started"); 
                         semUser.newCQUser("Little");

                }

                @Override
                protected void doPost(SlingHttpServletRequest request,
                        SlingHttpServletResponse response) throws ServletException,
                        IOException {

                }
    }

服务这里从Servlet上面调用： -

并且我将这个jar添加到osgi bundle但是用户没有创建程序正在打击并且debuging很好
