Re: I got message "can't looking for object..." when I restart ozone

Thank you for your reply :)

I am sorry, that I did not put this in the first time. This is full 
source code of init and main method. I attach full source in 
testozone.tar.gz with this mail already.

You can check MetBroker Project from "http://www.agmodel.net/MetBroker/"
this is project for connect world weather database together. I working 
to change matadata  from commercial oodb to ozone. and move MetBroker 
to Grid Infrastructure.

     public void init(OzoneInterface database){
         db = database;

         String name = MetCollectionImpl.class.getName();

         Object obj = null;

         try{
           System.out.println("looking Object name "+ObjName+" from db");
           obj = db.objectForName(ObjName);
           metc = (MetCollection)obj;
           System.out.println("get "+metc.getName()+" read ");          
testRead();
           testReadComplicate();          testDelete();

         }catch(Exception e){
           try { //Create new DB
               System.out.println("can't looking for object because: 
"+e);
               obj = db.createObject(name, 0,ObjName);
               System.out.println("create obj name:"+ obj);

               metc = (MetCollection) obj;

               metc.setName("OzoneMetBroker2");
               System.out.println("ObjectDB name: "+metc.getName()+" was 
created by me");

               testCreate();
           } catch(Exception e2) {
               System.out.println("Can't create DB: "+ e2);
           }
         }
     }

public static void main(String[] args) throws Exception{

       System.out.println("Start Local");

       String dbDir = "/java/testozone/ozon";
       System.out.println("Opening database at "+ dbDir);
       LocalDatabase database = new LocalDatabase();      if 
(!database.exists(dbDir)){
            database.create(dbDir);
       }
       database.open(dbDir, OzoneDebugLevel.ERROR_STR);

       database.reloadClasses();
       System.out.println("connect to ozone complete: "+database);

       MetTest msi = new MetTest();
       msi.init(database);
       System.out.println("end test");
     }



Thank you very much.
