Problem in retrieving search result

Question

Hi Experts,
I wrote Java Application for Search Using Index Management APIs.
I am not getting any result.
Just look at my code
<b>i have taken some Variable String x="" to test my code</b>
IIndexService indexService =
      (IIndexService)ResourceFactory.getInstance().getServiceFactory().getService("IndexmanagementService");
      <b> x=x+ "1"+ indexService.getID();</b>
       IFederatedSearch federatedSearch =
  (IFederatedSearch)indexService.getObjectInstance("federatedSearchInstance");
//  get list of all active indexes
//alternatively use the indexService to get indexes by index ID and add them to a list
      List listuser=indexService.getActiveIndexes();
      <b>x=x+ "  2  " + listuser.size();</b>
//  build IQueryEntryList
      SearchQueryListBuilder sqb = new SearchQueryListBuilder();
  sqb.setSearchTerm(query);
  IQueryEntryList qel = sqb.buildSearchQueryList(); 
  <b> x=x+ "  3  " + qel.size();</b>     
//search
  ISearchSession  session = federatedSearch.searchWithSession(qel, listuser,resourseContext);
      <b> x= x + "  4  " + session.getTotalNumberResultKeys();</b>   
      //get the Results
  ISearchResultList results = session.getSearchResults(1,session.getTotalNumberResultKeys());
   ISearchResultListIterator iter = results.listIterator();
      <b> x= x " 5  " results.size();</b> 
           while (iter.hasNext())
         ISearchResult result = iter.next();
     IResource resource = result.getResource();
       IURLGeneratorService url =
      (IURLGeneratorService)ResourceFactory.getInstance     ().getServiceFactory().getService(IServiceTypesConst.URLGENERATOR_SERVICE);
        uri=uri + url.getResourcePageUri(PathKey.CONTENT_ACCESS_PATH,resource.getAccessRID(),null).toString();
          <b> x=x+"  6  ";</b>     
          <b> x=x+ "  7  "+uri.length();</b>}
return x;
The output what i am getting is....
For this line <b> session.getTotalNumberResultKeys(); </b> i am getting output as 1 (one).
Means there is one result.
I am retrieving the results and storing it in 'results' list object
like this
ISearchResultList results = session.getSearchResults(1,session.getTotalNumberResultKeys());
When i say results.size() i am getting 0 as output.
What is this strange behaviour....?
Total results are 1(one)
When i try to retrieve them it says 0(zero) results.
When i perform normal search in protal there also i am getting only one result(when i search * as a search query).
the same i am doing it here.But  i am not able to retrieve the result.
To test this application , i am converting this java Class into Webservice and deploying it in searver.
The reason why i am converting it into webservice is , it will be used other portal i.e Sharepoint Portal.(They will call this webservice in their code)
Why is it happening so.
Any one has ideas , where it is going wrong.

HI Udit,
Yes i got the answer to it.
In my case the prblem was with the user credentilas.
When i run the same application from WebDynpro, it was working fine, meanse result list and result keys was same.
But when i run it as java application, i had the problem which you had.
So what i did is, I have checked which user it is taking in WebDynpro and which user it is taking in my java Application. Surprisingly it was different.
So tried with the same user, which it is taking in WebDynpro.
generally by default it takes <b>Guest</b>  user in WebDynpro.
So first try this application from webdynpro, if it works fine there.
Take the same user name and pass it from your java application.
It is the problem with user name only.
any way i am sending you my code , have look at it.
