Using my XML writer?

Question

Hi, I'm trying to write an xml writer in order to save games in my chess program. The writer works fine, but I want to make a static or at least public instance of it I can use at different places. Ao I tried to put it here but it says...
C:\Program Files\Xinox Software\JCreator LE\MyProjects\Exercises\Chess\ChessGame\GamePiece.java:11: unreported exception java.io.IOException; must be caught or declared to be thrown
     static XMLWriter xw = new XMLWriter("game.xml");
^
1 error
abstract class GamePiece extends Canvas
     static XMLWriter xw = new XMLWriter("game.xml");
// other methods follow
}I can get it to work by putting into the cunstructor of each child of GamePiece but I want just one running so that the different pieces can write to the same file when it's movePiece method is called.
Here is the code for the XMLWriter
import java.io.*;
public class XMLWriter
     String file;
     FileWriter fw;
     BufferedWriter bw;
     PrintWriter outFile;
     public XMLWriter(String name) throws IOException
          file = name;
          fw = new FileWriter (file);
          bw = new BufferedWriter (fw);
          outFile = new PrintWriter (bw);
          outFile.print ("<?xml version= \"1.0\"?>\n\n");
          outFile.print ("<GAME>\n");
     public void addMove(int fromX, int fromY, int toX, int toY)
          outFile.print ("\t<MOVE>\n");
          outFile.print ("\t\t<FROM_X>" + fromX + "</FROM_X>\n");
          outFile.print ("\t\t<FROM_Y>" + fromY + "</FROM_Y>\n");
          outFile.print ("\t\t<TO_X>" + toX + "</TO_X>\n");
          outFile.print ("\t\t<TO_Y>" + toY + "</TO_Y>\n");
          outFile.print ("\t</MOVE>\n");
     public void endRecord()
          outFile.print ("</GAME>\n");
          outFile.close();
}
