映射Java ArrayList<；定制类>；和Flex ArrayCollection

我目前正试图通过LCD将java ArrayList与Flex ArrayCollection进行映射。 我的Flex应用程序确实调用了返回ArrayList的Java方法，但我还没有设法检索ArrayList以在Flex端的DataGrid中显示它

JavaSide： 我有两门课： -Jco_test.java：它包含public ArrayList all（）方法 -java：它包含一个初始化某些变量的构造函数

    public class CustomClass {

    String airline;
    String cityFrom;
    String cityTo;
    Date flightDate;
    BigDecimal price;

    public CustomClass(String s1, String s2, String s3, Date d, BigDecimal bd){
        airline = s1;
        cityFrom = s2;
        cityTo = s3;
        flightDate = d;
        price = bd;
    }    
}

FlexSide：

• test.mxml：

          import mx.messaging.AbstractConsumer;
          import mx.collections.ArrayCollection;
          import mx.rpc.events.FaultEvent;
          import mx.rpc.events.ResultEvent;
          import mx.controls.Alert;
  
      public var flightList:ArrayCollection;
  
      public function ResultHandler(event:ResultEvent):void{
          flightList = (event.result as ArrayCollection);             
      }
  
      public function FaultHandler(event:FaultEvent):void{
          flightList = new ArrayCollection();
          ta.text = "Error id: " + event.fault.errorID + "\n";
          ta.text += "String: " + event.fault.faultString + "\n";
          ta.text += "Code: " + event.fault.faultCode + "\n";
          ta.text += "Detail: " + event.fault.faultDetail + "\n";
          ta.text += "Stack: \n" + event.fault.getStackTrace() + "\n";
      }
  

RemoteObject id=“ro”destination=“jco”result=“ResultHandler（事件）；”fault=“FaultHandler（事件）；”

我做错什么了吗？ 我还有一些疑问。。。我的ArrayList没有标题。如何检索DataGridColumn中的数据

谢谢你能提供的帮助。 问候

（很抱歉出现格式问题…）

我确实忘记了接球手和二传手。 现在，我可以在服务器日志中看到我要查找的值。但是Flex仍然无法显示数据

以下是日志：

我不确定DataGridColumn的datafield是否区分大小写，所以我更改了datafield以匹配每个字段

1观察

在CustomClass.java中添加getter和setter（我解决了我的问题=） 我犯了一个装订错误

我的dataGrid使用“flightList”作为数据提供者，但我没有将其定义为可绑定变量

非常感谢您的回答=）

您的数据字段中是否真的有大写字母，或者是打字错误？请编辑文章以更正代码格式。顺便说一句，数据域是航空公司还是航空公司？@bug-a-lot：我不确定数据域是否区分大小写。我更改了大写字母，以便匹配Java类中的字段@抱歉格式化，但是我的代码格式化有问题。。。不知道为什么，有时候，我的文字只是不想格式化。。。我现在更改了数据字段，它现在是airline（就像在java和actionscript类中一样）。
