Mapping Java ArrayList<CustomClass> and Flex ArrayCollection

I'm currently trying to map a java ArrayList with a Flex ArrayCollection, through LCDS. My Flex application does call the Java method that returns the ArrayList, but I haven't managed to retrieve the ArrayList to display it in a DataGrid, on Flex side.

JavaSide: I have 2 classes: - Jco_test.java: it contains the method public ArrayList all() - Customclass.java: it contains a constructor that initializes some variables

    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(event);" fault="FaultHandler(event);"

    <mx:Panel title="monTest" width="699" height="549" x="10">
        <mx:Button label="go" click="ro.all();"/>
        <mx:DataGrid dataProvider="flightList">
            <mx:columns>
                <mx:DataGridColumn dataField="AIRLINE" headerText="Airline" />
                <mx:DataGridColumn dataField="CITYFROM" headerText="From" />
                <mx:DataGridColumn dataField="CITYTO" headerText="To" />
                <mx:DataGridColumn dataField="FLIGHTDATE" headerText="Date" />
                <mx:DataGridColumn dataField="PRICE" headerText="Price" />
            </mx:columns>
        </mx:DataGrid>
        <mx:TextArea id="ta" width="100%" height="219"/>    
    </mx:Panel>

• CustomClass.as:

  [Bindable]
  [RemoteClass(alias="utils.CustomClass")]
  public class CustomClass{
      public var airline:String;
      public var cityFrom:String;
      public var cityTo:String;
      public var flightDate:Date;
      public var price:String;       
  }    
  

Am I doing something wrong? I still have some doubts... My ArrayList does not have headers. How can I retrieve the data in my DataGridColumn?

Thanks for any help you can provide. Regards.

(Sorry about the formatting issues...)

I had indeed forgotten the getter and the setters. Now, I can see in the server log the values I was looking for. But Flex is still not able to display the Data.

Here is the log:

I'm not sure about the DataGridColumn's datafield case sensitivity, so I changed the datafields to match each field.
