小编Mar*_*mic的帖子

关于Stack Overflow的其他问题已经解决了这个问题,但是所提供的答案都没有帮助我解决这个问题.

我正在尝试使用Apache HTTP Commons从applet上传一个介于10 kB到16 MB之间的文件.在我的本地环境中一切正常.

我只在我的生产服务器(Tomcat 6.0,https://www.dailyrazor.com/)上收到以下异常,无论文件大小如何:

org.apache.commons.fileupload.FileUploadException: Processing of multipart/form-data request failed. Read timed out

这是Commons IO的调试日志:

我ContentProvider在互联网上观看了一个关于如何定义和使用a 的课程ContentProvider.

我对使用名为的方法感到困惑getContentResolver().这种方法有什么回报？

我ContentProvider没有实例,代码就是这样写的getContentProvider().query().

我不明白是怎么ContentProvider运作的.

我创建了一个自定义对话框片段及其xml,如下所示:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_margin="5dp"

    android:padding="5dip" >

    <ListView
        android:id="@+id/product_list"
         android:background="@drawable/border_details"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
         />

    <RelativeLayout
        android:id="@+id/AddtoCart"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:layout_marginTop="10dp"

        android:background="#005959" >

        <Button
            android:id="@+id/button_addToCart"
            android:layout_width="250dp"
            android:layout_height="wrap_content"
            android:layout_centerInParent="true"
            android:background="@drawable/gradient_button"
            android:layout_marginTop="2dp"
            android:layout_marginBottom="2dp"
            android:text="@string/add_to_cart"
            android:textColor="#000000" />
    </RelativeLayout>

</RelativeLayout>

当我调用此对话框时,它将按照屏幕截图中的全屏显示:

如何将此对话框的大小限制为列表和按钮的高度？

如何删除多余的空白区域？

我想在整个应用程序中使用相同的线程池.为此,我可以让ExecutorService静态和全局,这样我可以调用ThreadUtil.executorService得到ExecutorService,当我需要它.

public class ThreadUtil {
    public static final ExecutorService executorService = Executors.newCachedThreadPool();
}

可以像这样实例化多个线程池吗？

另外,我的应用程序是TCP服务器.如果我不知道游泳池应该有多大,可以简单地使用newCachedThreadPool吗？

我正在使用custome.js,PIE.js并jquery1_7_2.js提交我的jsp

这是我的custome.js,仅此而已.

jQuery(document).ready(function(){
   jQuery(function() {

    if (window.PIE) {
        jQuery('#login-box, .sign-button, .new-user-btn, .grey-btn, .code-btn, #contact-email, #contact-email .continue, #contact-email .cancel').each(function() {
            PIE.attach(this);
        });
    }

});

})

在所有浏览器中一切正常.但在Firefox中,它向我显示了这个错误

Error: TypeError: PIE.attach is not a function
Source File: http://localhost:8080/MyApp/js/custom.js
Line: 6

请指导我解决这个问题.

编辑: 它显示我在这行PIE.js中的错误
