blackberry - 打包 Blackberry OAuth 应用程序抛出错误

Question

我正在创建一个应用程序，它将在 Twitter 上发布链接。以下代码拒绝为我打包，并抛出以下错误:

Error: Cannot run program "jar": CreateProcess error=2, The system cannot find the file specified

这是代码:

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 );                
            }
        });
    }
}

奇怪的是，如果我删除以下几行，它就可以正常打包:

authButton.setChangeListener( new FieldChangeListener( ) {
        public void fieldChanged( Field field, int context ) {
            if( field == authButton ) {
                   doAuth(authPin.getText());
            }
        }
    } );

任何帮助将不胜感激，因为我确实需要将现场监听器附加到此屏幕。

使用像 authButton.setChangeListener(null) 这样的代码，它确实可以成功打包，但是我确实需要使用 FieldChangeListener 的代码来执行某些操作。

确保您的 java bin 路径已在环境变量中设置。

并查看以下网站中的最后 3 篇帖子:

还要确保计算机上安装了 Java® 软件开发工具包 (Java SDK/JDK)，并且使用了正确版本的 Java SDK。
