Hi Kiran,
Here's some sample code that I've got of an abstract portal component that goes through the contents of a KM folder and displays the KM description for the file:
package com.graybar.portal.titleload;
import com.sapportals.portal.prt.component.*;
import java.io.File;
import java.util.ArrayList;
import com.sapportals.portal.prt.component.IPortalComponentResponse;
import com.sapportals.portal.security.usermanagement.*;
import com.sapportals.wcm.repository.*;
import com.sapportals.wcm.repository.service.IRepositoryServiceFactory;
import com.sapportals.wcm.util.uri.*;
public class TitleLoad extends AbstractPortalComponent {
    public void doContent(IPortalComponentRequest request, IPortalComponentResponse response) {
          response.write("starting... <BR>");     
          response.write("***************************** <BR>");
          IUser user = (IUser)request.getUser().getUser();
          IResourceContext resourceContext = new ResourceContext(user);
          // starting folder
          RID repositoryID = new RID("/documents/TitleLoad");
          // Get the Service
          IRepositoryServiceFactory repServiceFactory = null;
          try {
               repServiceFactory = ResourceFactory.getInstance().getServiceFactory();
          } catch (Exception ex) {
               ex.printStackTrace();
          if(repServiceFactory == null) {
               System.out.println("Repository Service Factory is null!!");
          try {
               IResource resource = ResourceFactory.getInstance().getResource(repositoryID, resourceContext);
               if( resource != null ) {
                    if (resource.isCollection()) {
                         ICollection collection = (ICollection)resource;
                         IResourceList children = collection.getChildren();
                         int resourceCounter = 0;
                         String attrType = new String();
                         response.write("size = " + children.size() + "<BR>");
                         IProperty prop = null;
                         String propValue = null;
                         String resRid = null;
                         for (int i = 0; i < children.size(); i++){
                              String validTo = new String();
                              ArrayList attributes = new ArrayList();
                              IResource ir = children.get(i);
                              if (ir.getRID() != null)
                                   resRid = ir.getRID().toString();
                              PropertyName propNameP = new PropertyName("http://sapportals.com/xmlns/cm", "description");
                              prop = ir.getProperty(propNameP);
                              response.write("before <BR>");
                              try {
                                   propValue = prop.getStringValue();
                              } catch (Exception e) {
                                   propValue = "";
                              response.write("after <BR>");
                              response.write("Name = " + ir.getName() + "; Description = " + propValue + "<BR>");
                              resourceCounter++;
               } else {
                    // resource not found
                    System.out.println("resource " + resource.getRID() + " does not exist");
          } catch( ResourceException e ) {
            // problem while retrieving the resource
            System.out.println("exception while trying to get resource " + e.getRID() + ": " + e.getMessage());
     response.write("finished <BR>");
