Hi,

You can use JCR Node API or Resource API to get child resource and adapt to Node API/Value Map

Node (Content Repository for Java Technology API Version 2.0)

Resource (Apache Sling 8 API)

ValueMap and his friends - Experience Delivers

Resource resource = resolver.getResource("/content/testsling/slingmodel");

ValueMap valueMap=resource.adaptTo(ValueMap.class);

response.getWriter().write("Output from ValueMap is First Name: "+valueMap.get("firstName").toString()+" Last Name: "+valueMap.get("lastName").toString()+" Technology: "+valueMap.get("technology").toString()+"");

  UserInfo userInfo = resource.adaptTo(UserInfo.class);

  response.getWriter().write("Output from Sling Model is First Name: "+userInfo.getFirstName()+" Last Name: "+userInfo.getLastName()+" Technology: "+userInfo.getTechnology());
