Packaging Blackberry OAuth app throwing error - blackberry

Question

I am creating an application that will post a link onto Twitter. The following code refuses to package up for me, throwing the following error:
Error: Cannot run program "jar": CreateProcess error=2, The system cannot find the file specified
Here is the code:
public class ShowAuthBrowser extends MainScreen implements OAuthDialogListener
{
private final String CONSUMER_KEY = "<Consumer>";
private final String CONSUMER_SECRET = "<Secret>";
private LabelField _labelStutus;
private OAuthDialogWrapper pageWrapper = null;
public StoreToken _tokenValue;
public BrowserField b = new BrowserField();
Manager _authManager;
Manager _pinManager;
ButtonField authButton;
TextField authPin;
public ShowAuthBrowser()
{
_authManager = new VerticalFieldManager(NO_VERTICAL_SCROLL |
NO_VERTICAL_SCROLLBAR);
_pinManager = new HorizontalFieldManager(NO_VERTICAL_SCROLL |
NO_VERTICAL_SCROLLBAR);
authButton = new ButtonField("OK");
authPin = new TextField(Field.EDITABLE);
_authManager.add(_labelStutus );
_authManager.add(b);
_pinManager.add(authButton);
_pinManager.add(authPin);
pageWrapper = new BrowserFieldOAuthDialogWrapper(b,CONSUMER_KEY,
CONSUMER_SECRET,null,this);
pageWrapper.setOAuthListener(this);
add(_pinManager);
add(_authManager);
authButton.setChangeListener( new FieldChangeListener( ) {
public void fieldChanged( Field field, int context ) {
if( field == authButton ) {
doAuth(authPin.getText());
}
}
} );
}
public void doAuth( String pin )
{
try
{
if ( pin == null )
{
pageWrapper.login();
}
else
{
this.deleteAll();
add(b);
pageWrapper.login( pin );
}
}
catch ( Exception e )
{
final String message = "Error logging into Twitter: " +
e.getMessage();
Dialog.alert( message );
}
}
public void onAccessDenied(String response ) {
updateScreenLog( "Access denied! -> " + response );
}
public void onAuthorize(final Token token) {
final Token myToken = token;
_tokenValue = StoreToken.fetch();
_tokenValue.token = myToken.getToken();
_tokenValue.secret = myToken.getSecret();
_tokenValue.userId = myToken.getUserId();
_tokenValue.username = myToken.getUsername();
_tokenValue.save();
UiApplication.getUiApplication().invokeLater( new Runnable() {
public void run() {
deleteAll();
Credential c = new Credential(CONSUMER_KEY,
CONSUMER_SECRET,
myToken);
PostTweet tw = new PostTweet();
String message="Testing BB App";
boolean done=false;
done=tw.doTweet(message, c);
if(done == true)
{
Dialog.alert( "Tweet succusfully..." );
close();
}
}
});
}
public void onFail(String arg0, String arg1) {
updateScreenLog("Error authenticating user! -> " + arg0 + ", " + arg1);
}
private void updateScreenLog( final String message )
{
UiApplication.getUiApplication().invokeLater( new Runnable() {
public void run() {
_labelStutus.setText( message );
}
});
}
}
The odd thing is, if I remove the following lines, it packages just fine:
authButton.setChangeListener( new FieldChangeListener( ) {
public void fieldChanged( Field field, int context ) {
if( field == authButton ) {
doAuth(authPin.getText());
}
}
} );
Any help would be appreciated as I really need the field listener attached to this screen.
With code like authButton.setChangeListener(null), it does package successfully however I do need code with FieldChangeListener to do something.

Make sure your java bin path is set in environment variable.

and take a look at the last 3 posts in the following website:

Also make sure The Java® software development kit (Java SDK/JDK) is installed on the computer, and a correct version of the Java SDK is used.
