 现在我想把上面的字符串改造成从数据库中读取，我改造的程序的部分代码如下：<?xml version="1.0" encoding="utf-8"?>

 xmlns="http://www.adobe.com/2006/mxml"

 layout="absolute" 
 viewSourceURL="index.html" 
 creationComplete="initApp()"
 > <mx:Script>
   <![CDATA[
  import mx.controls.Alert;
  import mx.utils.ArrayUtil;
        import mx.collections.ArrayCollection;
       
        //保存返回图片事件集合的内容
        [Bindable]
       public var imgList:Array;
       
       //初始化程序，调用图片对象的返回图片集，送将结果送给flex事件集
        public function initApp():void
            {
              src.getAllImg();
            }
   ]]>
    </mx:Script>
    <Binding source="sel.value" destination="shelf.selectedIndex" />
 <Binding destination="sel.value" source="shelf.selectedIndex" />
 
 <Binding source="angle.value" destination="shelf.angle" />

 <!--本地化远程返回图片的对象-->
   <mx:RemoteObject id="src" 
 destination="imageDB" 
 result="imgList=ArrayUtil.toArray(event.result)" 
 fault="Alert.show(event.fault.faultString,'Error')"
 />
 
 <local:DisplayShelf id="shelf"  
  dataProvider="{imgList}"
  horizontalCenter="0" verticalCenter="0" 
  borderThickness="5" borderColor="#FFFFFF" 
  enableHistory="false" width="100%" 
  /> ..... ...     但生成的代码后，图片显示了，但无论如何调整那个滑条都没效果！！我研究了都快两周了，效果还是不知道怎么加上去，哪位高手或者好心人帮我看下，告诉我为什么啊

Answer 1

相关的javabean代码为： //ImageInfo.java package cn.lx.image; import java.io.Serializable; public class ImageInfo implements Serializable { /** * */        private static final long serialVersionUID = 1L;        private int id;        private String advername;       private String adverpic;       private String adverkey;        private String advernumber;        private int intstatu; private String intcatalog;        private String area; private int istop;        public String getAdverkey()              return adverkey; }        public void setAdverkey(String adverkey)            this.adverkey = adverkey; }  .......................................            //其它的的get set方法 }  //DataServiceImpl.java         package cn.lx.image;    import java.sql.*;    import java.util.ArrayList;   public class DataServiceImpl {    // 查询图片,并返回图片记录          public ImageInfo[] getImages() {                  ArrayList imageList = new ArrayList();                   String sqlText = "select top 10 id,advername,adverpic,adverkey,advernumber,intstatu,intcatalog,are                a,istop from adver_active";                  ResultSet rs = executeQuery(sqlText);                  try {                         while (rs.next()) {                                   ImageInfo imageinfo = new ImageInfo();                                    imageinfo.setId(rs.getInt("id"));                                   imageinfo.setAdvername(rs.getString("advername"));                                   imageinfo.setAdverpic("http://192.168.18.99/"+"ad_pic/"+rs.getString("adverpic"));                                  imageinfo.setAdverkey(rs.getString("adverkey")); imageinfo.setAdvernumber(rs.getString("advernumber"));                                    imageinfo.setIntstatu(rs.getInt("intstatu")); imageinfo.setIntcatalog(rs.getString("intcatalog"));                                  imageinfo.setArea(rs.getString("area")); imageinfo.setIstop(rs.getInt("istop")); imageList.add(imageinfo); } ImageInfo[] images = new ImageInfo[imageList.size()];                          for (int i = 0; i < imageList.size(); i++) {                                  images = (ImageInfo) imageList.get(i); }                                        return images; } catch (SQLException e) { e.printStackTrace(); return null; } }  public Object[] getAllImg(){ return init().toArray(); }  private ArrayList init() { ArrayList list = new ArrayList(); ImageInfo[] images=getImages(); for(int i=0;i.getAdverpic()); return list; } }

Answer 2

哥们强烈关注,我也在研究,好象要安装data service.
等你的研究成果.

Answer 3

braig(braig) ，我已经装好了FDS，也就是支持data service，图片可以看到，就是没有效果啊，不过还是谢谢上面两位顶我的贴flex感觉用起来很好，效果也不错，就是中文资料太少了

Answer 4

嗯，Flex+Spring+Hibernate的商业软件，可以在线演示的http://www.mybaicai.com/tryout/
