"[SOLVED]:RapidMiner Integration with Java"

Hello,

I need to run a RapidMiner process in Java. Like explained in this link :   http://stackoverflow.com/questions/15834182/integration-of-rapidminer-in-java-application, 

    import com.rapidminer.Process;
    import com.rapidminer.RapidMiner;
    import com.rapidminer.operator.Operator;
    import com.rapidminer.operator.OperatorException;
    import com.rapidminer.operator.io.ExcelExampleSource;
    import com.rapidminer.tools.XMLException;
    import java.io.File;
    import java.io.IOException;
    import java.lang.Object;

    public class ReadRapidminerProcess {
      public static void main(String[] args) {
        try {
          
          RapidMiner.setExecutionMode(RapidMiner.ExecutionMode.COMMAND_LINE);
          RapidMiner.init();
          
          Process process = new Process(new File("C:\\Users\\Keshav\\.RapidMiner5\\repositories\\Local Repository\\lsvmtest.rmp"));
          process.run();

        } catch (IOException | XMLException | OperatorException ex) {
          ex.printStackTrace();
        }
      }
    }

I run the above code. The code compiled but gave following error during its run:

    Hi,

    disable assertions, they are not being maintained and will cause useless errors.

    Hello,

    I disabled assertions and I still get some errors though it has reduced.

    Update:
    After disabling assertions, I set right the rapidminer.home error by adding this line of code: 

    System.setProperty("rapidminer.home", "C:\\Program Files (x86)\\Rapid-I\\RapidMiner5");
    Now, the following error alone exists:

    UPDATE:
    Made some modifications to the code. 

     public class ReadRapidminerProcess {
          public static void main(String[] args) {
            try {
             
              RapidMiner.setExecutionMode(RapidMiner.ExecutionMode.COMMAND_LINE);
              System.setProperty("rapidminer.home", "C:\\Program Files (x86)\\Rapid-I\\RapidMiner5");
              RapidMiner.init();
              RepositoryLocation loc = new RepositoryLocation("//Local Repository/linsvmtest");
              IOObjectEntry entry = (IOObjectEntry) loc.locateEntry(); 
              Process process = new Process(new File("C:\\Users\\Keshav\\.RapidMiner5\\repositories\\Local Repository\\linsvmtest.rmp"));
              process.run();

            }
                   catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (XMLException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (OperatorException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } 
        catch (RepositoryException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
          }
        }
    The previous 'Process is not associated with a repository.' error is set right but I get the following error:

    Hi,

    you are doing the following: 

    IOObjectEntry entry = (IOObjectEntry) loc.locateEntry();
    however when you call locateEntry() on a repository location where a process lies, you will recieve a SimpleProcessEntry instead. This is why you are getting the ClassCastException.

    Hi,

    you can use the following snippet to load a process from a known repository and location: 

    Repository repo = RepositoryManager.getInstance(null).getRepository("Local Repository");
    RepositoryProcessLocation processLocation = new RepositoryProcessLocation(new RepositoryLocation(repo.getLocation(), "nameOfMyProcess"));
    Process process = processLocation.load(null);
    process.run();
    Note that you can load processes from other sources as well, e.g. a File or the XML string representation.

    Hello,

    I implemented the code as directed: 

        
        import com.rapidminer.Process;
        import com.rapidminer.RapidMiner;
        import com.rapidminer.operator.Operator;
        import com.rapidminer.operator.OperatorException;
        import com.rapidminer.operator.io.ExcelExampleSource;
        import com.rapidminer.tools.XMLException;
        import java.io.File;
        import java.io.IOException;
        import java.lang.Object;
        import com.rapidminer.repository.RepositoryLocation;
        import com.rapidminer.repository.RepositoryException;
        import com.rapidminer.repository.IOObjectEntry;
        import com.rapidminer.repository.RepositoryManager;
        import com.rapidminer.RepositoryProcessLocation;
        
        
    public class ReadRapidminerProcess {
          public static void main(String[] args) {
            try {
             
              RapidMiner.setExecutionMode(RapidMiner.ExecutionMode.COMMAND_LINE);
              System.setProperty("rapidminer.home", "C:\\Program Files (x86)\\Rapid-I\\RapidMiner5");
              RapidMiner.init();
              /*
              RepositoryLocation loc = new RepositoryLocation("//Local Repository/linsvmtest");
              IOObjectEntry entry = (IOObjectEntry) loc.locateEntry(); 
              Process process = new Process(new File("C:\\Users\\Goutham\\.RapidMiner5\\repositories\\Local Repository\\linsvmtest.rmp"));
              process.run();
              */
              Repository repo = RepositoryManager.getInstance(null).getRepository("Local Repository");
              RepositoryProcessLocation processLocation = new RepositoryProcessLocation(new RepositoryLocation(repo.getLocation(), "linsvmtest"));
              Process process = processLocation.load(null);
              process.run();

            }
                   catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (XMLException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (OperatorException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } 
        catch (RepositoryException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
          }
        }
    However, I am not able to compile it.(drjava)

    Compiler Output: 

    Error: cannot find symbol
      symbol:   class Repository
      location: class ReadRapidminerProcess
    Can you please tell me what should I import to remove this error? Where is the class Repository found?

    Thank you very much for your prompt replies!

    Regards,

    Hi,

    Repository is an interface in the package com.rapidminer.repository in the main RapidMiner Studio project.

    Is there any way to get the JAR? I am already scouring the net and could not obtain it.
