Properties file

[Fisher Daniel]

Dear,
I have properties file that i have to set with new value.
But after i set with new value, the size of that properties size is 0kb...
This is the codes:

import java.util.*;
import java.io.*;
public class TestUtil
{
public static void main( String[] args )
{
TestUtil a = new TestUtil();
a.setScheduleProperties( "ThreadUserCancel" ); 
}

public synchronized void setScheduleProperties( String nameThread )
  {
      Properties prop = LoadProperties( "schedule.properties" );
      try
      {
          File data = new File ( getClass().getResource( "schedule.properties" ).toString().substring(5) );
          FileOutputStream fis = new FileOutputStream( data );
          prop.put( nameThread, "123" );
          prop.store( fis, "" );
          fis.close();         
      }
      catch( Exception e )
      {
          e.printStackTrace();
      }
  }
 
    public Properties LoadProperties( String classPath )
    {
        InputStream is = getClass().getResourceAsStream( classPath );
        if( is == null )
        {
            System.err.println( "Was unable to open '" + classPath + "'!" );       
            return( null );
        }
        Properties dbProps = new Properties();
        try
        {
            dbProps.load( is );
        }
        catch( Exception e )
        {
            System.err.println( "Can't read the properties file. " +
                                "Make sure '" + classPath + "' is in the CLASSPATH" );
          
            return( null );
        }
return( dbProps );
    } 
}

Can you help me?
thanks for your attention

i'm guessing something strange in your environment since i just ran your code successfully on my machine here (win2k). i started with schedule.properties containing:
a = a
b = b
and ended up with:

b=b
a=a
ThreadUserCancel=123
