我试图将一个字符串消息发送到weblogic服务器中创建的JMS队列.我使用Eclipse ide,当我运行我的Web应用程序时,我得到以下错误,并且tomcat服务器被关闭.错误是

我开发了一个Android应用程序来显示饼图.我用过这个achartengine库来做这个.使用下面的代码,我得到饼图输出,其中3个部分标记为categorySeries中提到的.我想在饼图上显示百分比值.我怎样才能做到这一点？

public static final GraphicalView getPieChartView(Context context,
             CategorySeries dataset, DefaultRenderer renderer) {
         checkParameters(dataset, renderer);
         PieChart chart = new PieChart(dataset, renderer);

         return new GraphicalView(context, chart);
     }

     private static void checkParameters(CategorySeries dataset,
             DefaultRenderer renderer) {
         if (dataset == null
             || renderer == null
             || dataset.getItemCount() != renderer
                .getSeriesRendererCount()) {
             throw new IllegalArgumentException(
                     "Dataset and renderer should be not null and the dataset number of items should be equal to the number of series renderers");
         }
     }     

这是我的onCreate方法

 Bundle bundle = …

我从android中的sms消息中获取日期作为时间戳,以秒为单位或从epoch开始.我需要使用java将其显示为标准日期和时间.

int date      = (cursor.getColumnIndex(SmsReceiver.DATE));

这会返回一些数字,如1308114404722.

使用此编号并显示为当前日期的过程是什么

我在uiview子类中创建了一个活动指示器和一个标签,并在许多不同的tab中调用它.除了Graph Hosting视图(CPTGraphHostinView)之外,它在我调用它的大多数地方都能正常工作.在这个特定的视图中,subView看起来是颠倒的.标签位于微调器上方.我尝试使用imageview而不是标签,并使用相同的倒置图像.

这是我的initWithframe方法

- (id)initWithFrame:(CGRect)frame {

    self = [super initWithFrame:frame];
    if (self) {
       // Initialization code.

        NSLog(@"AI: init with frame");

    spinnerView = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhiteLarge];
    spinnerView.center = self.center;       
    [self addSubview:spinnerView];

    UILabel* loadingMsg = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 90.0f, 30.0f)];
    loadingMsg.center =  CGPointMake(spinnerView.center.x , spinnerView.center.y + spinnerView.bounds.size.height/2 +10);
    loadingMsg.textAlignment = UITextAlignmentCenter;
    loadingMsg.backgroundColor = [UIColor clearColor];
    loadingMsg.text = @"loading";
    [self addSubview:loadingMsg];


}
    return self;
}

这里是对activityIndi​​cator的调用,在视图中加载了

ob_activityobject = [[ActivityIndicator alloc] initWithFrame:self.view.bounds];

    [ob_activityobject showInView:self.view];
