Error creating jar

Question

Hi everyone! I'm developing a mobile application for an nokia n95. However a got to an error that I'm finding difficult to deal with.
This is the code i'm testing:
import javax.microedition.location.*;
import javax.microedition.lcdui.*;
public class touristguide extends Canvas {
     public Criteria cr;
     public double lon;
     public double lat;
     public void Locator(){
          Criteria cr= new Criteria();
          cr.setHorizontalAccuracy(500);
          //Get an instance of the provider
          LocationProvider lp=null;
               try {
                    lp = LocationProvider.getInstance(cr);
               } catch (LocationException e1) {
                    // TODO Auto-generated catch block
                    e1.printStackTrace();
               Location l=null;
               try {
                    l = lp.getLocation(120);
               } catch (LocationException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
               } catch (InterruptedException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
          QualifiedCoordinates qc = l.getQualifiedCoordinates();
          if(qc != null ) {
               // Use coordinate information
               lat = qc.getLatitude();
               lon = qc.getLongitude();
               System.out.println ("latitude: " + lat);
     protected void paint(Graphics g){
          g.drawString("longitude = " + lon,0,0,Graphics.LEFT | Graphics.TOP);
          g.drawString("latitude = " +lat, 0, 20, Graphics.LEFT | Graphics.TOP);
When i try to run this code there's a window showing the following errors:
Jar file could not be initialized.
Caught exception:
java.util.zip.ZipException: invalid entry compressed size (expected 478 but got 481 bytes)
at java.util.zip.ZipOutputStream.closeEntry(Unknown Source)

com.symbian.tools.j2me.sei.emulator.Main.main(Main.java:49)
Has anyone faced this kind of errors? What should I do?
thanks in advance
