创建会话不起作用

Question

我在这里遵循此代码http://helpx.adobe.com/experience-manager/using/submitting-mobile-form-data-cq.html。首先，我尝试使用createuser.json.jsp中的以下代码创建会话，该代码在作者实例上运行并且工作正常 -

   <%@include file="/libs/foundation/global.jsp"%>
   <%@ page import="org.apache.sling.jcr.api.SlingRepository" %>
   <%@ page import="com.day.cq.security.UserManager" %>
     <%@ page import="com.day.cq.security.UserManagerFactory" %>
  <%@ page import="com.day.cq.security.User" %>
   <%@ page import="com.day.cq.security.Authorizable" %>
  <%@ page import="com.day.cq.security.profile.Profile" %>
   <%@ page import="java.util.Iterator" %>
  <%@ page import="java.util.List" %>
 <%@ page import="java.util.ArrayList" %>
 <%@ page import="javax.jcr.Repository" %>
 <%@ page import="javax.jcr.Session" %>
 <%@ page import="javax.jcr.SimpleCredentials" %>
 <%@ page import="org.apache.jackrabbit.commons.JcrUtils" %>
<%@ page import="org.apache.sling.commons.json.io.*" %><%

 final SlingRepository repos = sling.getService(SlingRepository.class);
 final UserManagerFactory umFactory = sling.getService(UserManagerFactory.class);
 Session session = null;
 try{
 session = repos.loginAdministrative(null); // I'm able to create session
   catch (Exception e)
   {
 System.out.println("Exception Occured: " + e.getMessage());
    }
  finally
   {
  session.logout(); 
 session = null;
  }%>

但是上面用于创建会话的代码在发布实例上不起作用。因此，我修改了下面的代码并尝试在作者实例上运行，但在这种情况下，不会调用createuser.json.jsp。我没有看到我添加的Sysout声明 -

 <%@include file="/libs/foundation/global.jsp"%>
 <%@ page import="org.apache.sling.jcr.api.SlingRepository" %>
 <%@ page import="com.day.cq.security.UserManager" %>
<%@ page import="com.day.cq.security.UserManagerFactory" %>
  <%@ page import="com.day.cq.security.User" %>
 <%@ page import="com.day.cq.security.Authorizable" %>
 <%@ page import="com.day.cq.security.profile.Profile" %>
  <%@ page import="java.util.Iterator" %>
 <%@ page import="java.util.List" %>
 <%@ page import="java.util.ArrayList" %>
  <%@ page import="javax.jcr.Repository" %>
  <%@ page import="javax.jcr.Session" %>
   <%@ page import="javax.jcr.SimpleCredentials" %>
  <%@ page import="org.apache.jackrabbit.commons.JcrUtils" %>
   <%@ page import="org.apache.sling.commons.json.io.*" %><%
  final SlingRepository repos = sling.getService(SlingRepository.class);
  final UserManagerFactory umFactory = sling.getService(UserManagerFactory.class);
  try
   { System.out.println("Hello session creating");
     Repository repository = JcrUtils.getRepository("http://somehost:4502/crx");
        Session session = repository.login(new SimpleCredentials("admin",  
      "admin".toCharArray()),"crx.default"); 
     System.out.println("session: " + session);
     catch (Exception e)
      {
   System.out.println("Exception Occured: " + e.getMessage());
     }
   finally
    {
    session.logout(); 
   session = null;
    }%>

如果我删除以下行，则调用createuser.json.jsp。

     Repository repository = JcrUtils.getRepository("http://somehost:4502/crx");
        Session session = repository.login(new SimpleCredentials("admin",
      "admin".toCharArray()),"crx.default");       

请让我知道我在这里做错了什么。感谢您的帮助。
