Need help with XMLEncoder

Hello,

I'm new to XMLEncoder and trying to grasp it's basics.

This works fine:

###############################################################
import java.beans.*;
import java.io.*;

public class TestIntegrated
{
    private int value;

    public TestIntegrated(){
        value = 0;
    }

    public int getValue(){ return value; }
    public void setValue(int value){ this.value = value; }

    public static void main(String[] args)
         throws FileNotFoundException{
        TestIntegrated t = new TestIntegrated();

        t.setValue(5);

        XMLEncoder e = new XMLEncoder(
             new BufferedOutputStream(
             new FileOutputStream("Test.xml"))
         );

         e.writeObject(t);
         e.close();
     }
}
###############################################################

If I split this in two Classes, it won't work anymore.
The error message is:

java.lang.IllegalAccessException: Class sun.reflect.misc.Trampoline
can not access a member of class Test with modifiers "public"
Continuing ...
java.lang.Exception: XMLEncoder:
discarding statement XMLEncoder.writeObject(Test);
Continuing ...

code:

###############################################################
import java.io.*;

class Test implements Serializable{
    private int value;

    public Test(){
        value = 0;
    }

    public int getValue(){ return value; }
    public void setValue(int value){ this.value = value; }
}
###############################################################
import java.beans.*;
import java.io.*;

public class TestMain
{
    public static void main(String[] args) throws FileNotFoundException{
        Test t = new Test();

        t.setValue(5);

        XMLEncoder e = new XMLEncoder(
             new BufferedOutputStream(
             new FileOutputStream("Test.xml"))
         );

         e.writeObject(t);
         e.close();
     }
}

Any Ideas why this won't work? I'm using java version 1.5.0_09.

Thanks, Manuel Kasten
