Compilation error

Hi,

I downloaded the following code from net :

Here is the code for my main class (OzoneTest.java):
import java.io.*;
import org.ozoneDB.*;


public class OzoneTest {
  public static final String DB_DIR = "/Java/OzoneTest/Database";

  public OzoneTest() throws Exception {
    System.out.println(getClass().getName()+" starting.");

    // Create a local database instance
    LocalDatabase db = new LocalDatabase();

    // Try to open the database
    try {
      System.out.println( "Opening database" );
      db.open(DB_DIR);
    } catch(Exception e ) {
      // No database found, create one.
      System.out.println( "No database found, creating one." );
      db.create(DB_DIR);

      // Try to open the database
      db.open(DB_DIR);
    }

    // Create a person info object
    PersonInfo2 personInfo = (PersonInfo2)
db.createObject(PersonInfo2Impl.class.getName(),
        OzoneInterface.Public, "PersonInfo2");

    personInfo.addToNames("ZZZZ");
    personInfo.addToNames("AAA");
    personInfo.addToNames("JJHS");

    System.out.println(getClass().getName()+" finished.");
  }

  public static void main(String[] args) throws Exception {
    OzoneTest ozoneTest = new OzoneTest();
  }
}

Here is the code for my persistent class:

Here is the Interface (PersonInfo2.java):

import java.util.*;
import org.ozoneDB.*;

public interface PersonInfo2 extends OzoneRemote {
    public void setName( String name );
    public String getName();
    public void addToNames(String name);
    public Vector getNames();
}

Here is the implementation (PersonInfo2Impl.java):

import java.util.*;
import org.ozoneDB.*;

public class PersonInfo2Impl extends OzoneObject implements PersonInfo2
{
  private String name;
  private Vector names;

  public void setName(String name) {
    this.name = name;
  }

  public String getName() {
    return name;
  }

  public String toString() {
    return "PersonInfo for "+getName();
  }

  public void addToNames(String name) {
    if( names == null )
      names = new Vector();
    names.add(name);
  }

  public Vector getNames() {
    return names;
  }
}
Now when I compile it thru ozoneAnt (using build.xml), I get following
error :

BUILD FAILED
Infact this error I am getting for nearly all the sample examples.
PL. EXPLAIN and how to rectify it.
