RM integration to Java (Text Mining) - Repository Problem

I'm new to integrating RM to Java. I have a process that applies the model and word list I have stored using the Naive Bayes classification. I want to integrate that process to my Java application.

But I keep getting this problem with the repository: 

Process run
INFO: Process starts

I am following this http://rapid-i.com/rapidforum/index.php/topic,3862.msg14364.html#msg14364.
This is my code. 


try {
            
           RapidMiner.setExecutionMode(RapidMiner.ExecutionMode.COMMAND_LINE);
            RapidMiner.init();
           
           RepositoryLocation location = new RepositoryLocation("//NewLocalRepository/TrendClass(70%)/Apply Model (Oct Data)"); 
             
           ProcessEntry pEntry = (ProcessEntry) location.locateEntry();         

           String xmlprocess = pEntry.retrieveXML();
           Process process = new Process(xmlprocess);
           
           RepositoryLocation objectsLoc = new RepositoryLocation("//NewLocalRepository/TrendClass(70%)/WordList");
           IOObjectEntry entry = (IOObjectEntry) objectsLoc.locateEntry();    
           
            IOObject myObject;
            myObject = entry.retrieveData(null);
            IOContainer ioInput = new IOContainer(new IOObject[] {myObject});
            
            IOContainer ioResult = process.run();
            IOObject result = ioResult.getElementAt(0);
      
            if (ioResult.getElementAt(0) instanceof ExampleSet) {
            ExampleSet resultSet = (ExampleSet)ioResult.getElementAt(0);
            System.out.println(result);
            int i=0;
            for (Example example : resultSet) {
                 Iterator<Attribute> allAtts = example.getAttributes().allAttributes();


                 while(allAtts.hasNext()) {
                     Attribute a = allAtts.next();
                   if(i<=3)
                     System.out.print(a.getName()+ "  ");

                     i++;
                 }
            }
            System.out.println("\n");
         for (Example example : resultSet) {
             Iterator<Attribute> allAtts = example.getAttributes().allAttributes();


             while(allAtts.hasNext()) {
                 Attribute a = allAtts.next();

                         if (a.isNumerical()) {
                                 double value = example.getValue(a);
                                 System.out.print(value+ " " );
                                 //System.out.println("\n");

                         } else {
                                 String value = example.getValueAsString(a);
                                 System.out.print(value+ " ");
                                 //System.out.println("\n");
                         }
                  }
             System.out.println("\n");
       }
        }
           
            
           
          } catch (IOException | XMLException | OperatorException ex) {
            ex.printStackTrace();
          } catch (RepositoryException ex) {
            Logger.getLogger(RMPrototype.class.getName()).log(Level.SEVERE, null, ex);
        }

    Hi,

    I'm afraid the example I posted there is not working in case your process makes use of parameters resolving local repository locations. Because the process itself is not linked to a repository location if created that way, it does not know where to find the specified files. To fix this, add 

    process.setProcessLocation(new RepositoryProcessLocation(location));
    after you have created your process.

    Regards,
    Marco
