Finding uniqueName from ObjectId of the portlet and other way round

When your working with Portal Model then you might need a way to figure out unique name of the portlet from its ObjectId and other way. I built this POC to do that. In

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

import javax.naming.InitialContext;
import javax.naming.NamingException;
import javax.portlet.GenericPortlet;
import javax.portlet.PortletException;
import javax.portlet.PortletRequest;
import javax.portlet.PortletResponse;
import javax.portlet.RenderRequest;
import javax.portlet.RenderResponse;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import com.ibm.portal.portletmodel.admin.PortletDefinitionList;

public class PortletUniqueNamePortlet extends GenericPortlet{
 PortletModelHome portletModelHome;
 
 public void init() throws PortletException {
  System.out.println("Entering PortalPOCPortlet.init()");
  try {
   InitialContext context = new InitialContext();
   portletModelHome =(PortletModelHome) context.lookup("portal:service/model/PortletModel");
   System.out.println("PortletModelHome " + portletModelHome);
  } catch (NamingException e) {
   e.printStackTrace(System.out);
  }
  System.out.println("Entering PortalPOCPortlet.init()");
 }

 protected void doView(RenderRequest request, RenderResponse response)
   throws PortletException, IOException {
  response.setContentType("text/html");
  response.getWriter().println("Object Id of the sitemap portlet " + getObjectIdOfPortlet(request, response, "wps.p.Sitemap"));
  response.getWriter().println("
Unique Name of the sitemap portlet " + getUniqueNameOfPortlet(request, response, getObjectIDStr(getObjectIdOfPortlet(request, response, "wps.p.Sitemap"))));
  
 }
 
 public static String getObjectIDStr(ObjectID objectID){
  String temp = objectID.toString();
  int firstInd = temp.indexOf("'");
  String result = temp.substring(firstInd+1, temp.indexOf("'", firstInd+1 ));
  return result;
 }
 
 public ObjectID getObjectIdOfPortlet(PortletRequest request, PortletResponse response, String portletUniqueName){
  System.out.println("Entering PortalPOCPortlet.getObjectIdOfPortlet()");
  try {
   AdminPortletModel  adminModel = portletModelHome.getPortletModelProvider().getAdminPortletModel((HttpServletRequest)request, (HttpServletResponse)response);
   PortletDefinition portletDef = adminModel.getPortletDefinitionList().getLocator().findByUniqueName(portletUniqueName);
   return portletDef.getObjectID();
  }  catch (ModelException e) {
   e.printStackTrace();
  }
  System.out.println("Exiting PortalPOCPortlet.getObjectIdOfPortlet()");
  return null;
 }
 
 public String getUniqueNameOfPortlet(PortletRequest request, PortletResponse response, String portletObjectId){
  System.out.println("Entering PortalPOCPortlet.getUniqueNameOfPortlet()");
  try {
   AdminPortletModel  adminModel = portletModelHome.getPortletModelProvider().getAdminPortletModel((HttpServletRequest)request, (HttpServletResponse)response);
   PortletDefinitionList portletDefinitionList = adminModel.getPortletDefinitionList();
   Iterator portletDefinitionIterator = portletDefinitionList.iterator();
   while(portletDefinitionIterator.hasNext()){
    PortletDefinition portletDefinition = portletDefinitionIterator.next();
    String currentObjectIdStr = getObjectIDStr(portletDefinition.getObjectID()); 
    if(currentObjectIdStr.equals(portletObjectId)){
     return portletDefinition.getObjectID().getUniqueName(); 
    }
   }
  }  catch (ModelException e) {
   e.printStackTrace();
  }
  System.out.println("Not able to find portlet for given portletObjectId");
  return null;
 }
}
