Packaging Blackberry OAuth app throwing error

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.
