SOA Service client: Change Object Ownership

How about changing project ownership ?
In data Migration you create the Teamcenter object using DBA user due to all access but it may required that created object should belong to other user and group then we need to change the ownership

To change the object ownership we need
1) Object whose ownership to be changed //Get the object by UIDs using  API loadObjects belong to class DataManagementService
2) User->User object
3) Group-> Group object

How do you find the User and Group ?
To find the User and Group you need savedQuery which should be available in Teamcenter Query Builder,If not available create it which will query User and Group for you.

Note: Must read code comment

//Find user using User ID ->String user represent User ID
 public ModelObject findUser(Connection connection, String user)

 {

  ImanQuery query = null

  //SavedQueryService class is in package com.teamcenter.services.strong.query
  SavedQueryService queryService = SavedQueryService.getService(connection);
  try
  {
   GetSavedQueriesResponse savedQueries = queryService.getSavedQueries();
   if (savedQueries.queries.length == 0)
   {
    return null;
   }
   for (int i = 0; i < savedQueries.queries.length; i++)
   {
    //__WEB_find_user -> Query in Query builder to find the user
    if (savedQueries.queries[i].name.equals("__WEB_find_user"))
    {
     query = savedQueries.queries[i].query;
     break;
    }

   }

  }
  catch (ServiceException e)
  {
   System.out.println(e.getMessage());
   return null;
  }
  if (query == null)
  {
   System.out.println("There is not an 'Item Name' query.");
   return null;
  }
  try
  {
   SavedQueryInput savedQueryInput[] = new SavedQueryInput[1];
   savedQueryInput[0] = new SavedQueryInput();
   savedQueryInput[0].query = query;
   savedQueryInput[0].maxNumToReturn = 25;
   savedQueryInput[0].limitListCount = 0;
   savedQueryInput[0].limitList = new ModelObject[0];
   savedQueryInput[0].entries = new String[]{"User ID" };//Attribute in Query to search by
   savedQueryInput[0].values = new String[1];
   savedQueryInput[0].values[0] = user;//Value for the search attribute
   savedQueryInput[0].maxNumToInflate = 25;

   //Execute Query to find the User
   ExecuteSavedQueriesResponse savedQueryResult = queryService.executeSavedQueries(savedQueryInput);
   SavedQueryResults found = savedQueryResult.arrayOfResults[0];

   // System.out.println("Found Users:");

   ModelObject[] modelObjs = found.objects;

   return modelObjs[0]; //User object
