get all the child node name in the parent nodepath

[sunitac70336244]

Dear All,

I have below content structure in AEM-6.4

My parent content nodepath is /content/VignetteContent/plan

Now my requirement is that I want all the child nodes like plan-104105 , location-9999 etc. with the JCR property Value.I have written below code. But I am not getting.

import java.io.IOException;
import java.util.Iterator;

import javax.servlet.ServletException;

import org.apache.felix.scr.annotations.sling.SlingServlet;
import org.apache.sling.api.SlingHttpServletRequest;
import org.apache.sling.api.SlingHttpServletResponse;
import org.apache.sling.api.resource.Resource;
import org.apache.sling.api.resource.ResourceResolver;
import org.apache.sling.api.servlets.SlingAllMethodsServlet;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

// localhost:4502/bin/sunita/myServlet.html?planID=104105&locationID=9999

@SlingServlet(paths = "/bin/sunita/myServlet", extensions = "html", methods = "GET")

public class TitleSlingServlet extends SlingAllMethodsServlet {

Logger log = LoggerFactory.getLogger(this.getClass());
private static final long serialVersionUID = 1L;
ResourceResolver resourceResolver;

public void doGet(SlingHttpServletRequest request, SlingHttpServletResponse response) throws ServletException, IOException {
  response.setContentType("text/html");
  try {

   String planID = request.getParameter("planID");
   String locationID = request.getParameter("locationID");
   log.info("planID is *********===*****  " + planID + " +++locationID is *********===*****  " + locationID);

   // Get the resource (a node in the JCR) using ResourceResolver from the request
   resourceResolver = request.getResourceResolver();
   Resource resource = resourceResolver.getResource("/content/VignetteContent/plan");
   Iterator<Resource> children = resource.listChildren();
   log.info(" children for nodepath is *****=== " + children.hashCode());
   while (children.hasNext()) {
    Resource child = children.next();
    String childNodeName = child.getName();
    log.info(" childNodeName is *****=== " + childNodeName);

   }

  
  }

  catch (Exception e) {
   response.getWriter().println("<br />Can't read planID/locationID. make sure the suffix path exists!");
   log.error(e.getMessage());
  }
  response.getWriter().close();

}

}

Please help me on this.

Please check below sample code :

It seems there might be multiple nodes under the parent node that you have. If you know that there would always be two levels of nodes inside "/content/VignetteContent/plan" node you could continue using this code with a little twich.

Other wise if you are not sure on the number of levels, you should be using a query to get all the nodes.

resourceResolver = request.getResourceResolver();

  Session session1 = resourceResolver.adaptTo(Session.class);

  if (session1.nodeExists("/content/VignetteContent/plan")) {

  javax.jcr.Node parentNode = session1.getNode("/content/VignetteContent/plan");

  if (parentNode.hasNodes()) {

  java.util.Iterator<javax.jcr.Node> levelOnechildren = parentNode.getNodes();

  while (levelOnechildren.hasNext()) {

  javax.jcr.Node planNode = levelOnechildren.next();

  log.info(" planNode name is *****=== " + planNode.getName());

  if (planNode.hasNodes()) {

  java.util.Iterator<javax.jcr.Node> leveltwochildren = planNode.getNodes();

  while (leveltwochildren.hasNext()) {

  javax.jcr.Node locationNode = leveltwochildren.next();

  log.info(" Location Node name is *****=== " + locationNode.getName());

  }

  }

  }

  }

  }

Please be advised that there might be compilation errors as I have written this snipped in a simple note pad.

Hope this helps.

Thanks
