El problema es q tengo q guardar en un archivo un Vector con objetos de esta clase:

painter.setColor(lineColor);
painter.drawLine(ixpz[0],iypz[0],ixpz[1],iypz[1]);
painter.drawLine(ixpz[1],iypz[1],ixpz[2],iypz[2]);

/*for (int c = 0; c < 4; c++)
System.out.println("X:"+xpz[c]+" Y:"+ypz[0]);*/
}
}

y lo intento guardar asi:

public void saveFile(String path)
{ try
{




myOutFileStream = new java.io.FileOutputStream (path);

myOutZipStream = new java.util.zip.GZIPOutputStream(myOutFileStream);

myOutObjetStream = new java.io.ObjectOutputStream(myOutZipStream);

System.out.println("Beguin 1");
myOutObjetStream.writeObject(parches);

myOutObjetStream.flush();
System.out.println("Finish");
myOutObjetStream.close();
myOutFileStream.close();



System.out.println(path);
}
catch(Exception o)
{
System.out.println(o);
}
}

pero m sale esta excepcion:

java.io.NotSerializableException: sun.java2d.SunGraphics2D

no se por q...
si alguien m puede ayudar lo agradecere mucho....:P

tu problema se soluciona poniendo delante del painter transient para que cuando guardes tus datos lo pase por alto, queda de esta forma

transient java.awt.Graphics painter;
