Flex RPC mapping Java nested classes to ActionScript classes

We are calling a Java method in our project using
RemoteObject the value returned by the java method is a ArrayList
containing instances of a class say ParentClass with some nested
classes.
The structure of ParentClass(Java) is something like this
class ParentClass {
//some primitives
private ChildClassA childAInstance;
private ChildClassB childBInstance;
//getters setters
We have created similar class structure on the ActionScript
side, the ActionScript classes(ParentClass,ChildClassA
,ChildClassB) have been properly annotated with the [RemoteClass]
metadata tag,
The problem is that though i'm getting the primitive data
members of the ParentClass through RPC in my corresponding AS
ParentClass class i'm getting an runtime exception trying to access
ChildClassA,ChildClassB members.
Am i missing something, exactly the same scenario is
mentioned in this article
http://www.adobe.com/devnet/flex/articles/complex_data.html
But the Object.registerClass method mentioned in the tutorial
is giving me compilation error, the sample code attached with the
article is corrupt zip too.
Please help me out on this

JAXB will create classes from an XML schema, SAX is a parser library and JAXP is a library of XML a bunch of XML tools.
I don't care for JAXB too much. I would skip it and go right to the JAX-RPC spec (WebServices).

I think GraniteDS has a tool for it.

Flex Builder stops compile new ActionScript classes

Hello,
Does anyone knows what could cause Flex Builder 3.4 stops compiling NEW ActionScript classes? I have been working on Flex project for a while, we have some MXML and .as files (less than 200). This morning Flex Builder suddenly stopped detecting errors in new as classes, but not so for older classes. Thanks and appreciate your help.
- Weiping

Are your new classes referenced from the old code? Mxmlc employs a questionable form of "as-needed" linking, so classes that are not referenced from the main application are not even compiled. This referencing requirement is recursive; that is, any classes that are to be included have to be referenced from the main application, or from classes referenced by the main application, or from classes referenced by classes referenced by the main application, and so on. But if your new classes are not referenced at all from the old code, they will be ignored.

Mapping existing actionscript class (mx.collections.SortField) to java

Hi,
I would like to map the existing SortField actionscript class on a SortField class on my java backend.
Is it possible to map an actionscript class from standard flex API to a java class? If so, how?
Thanks

Yeah, there is something awry with your mapped classes. You don't use the java source files to map your classes, you use AS3
classes that are designated to which classes they map to on the backend. Observe..
package shared.servicevos
   import flash.events.EventDispatcher;
   import flash.events.IEventDispatcher;
   [Bindable]
   [RemoteClass(alias="amf.ShopperVO")]
   public class ShopperVO
       public var shopperId:int;
       public var shopperLocation:String;
       public var shopDate:Date;
       public var shopperAddress:Address
If you notice the the metadata beginning with "RemoteClass", I am telling Flex "when you see an object that comes in with this type "alias" it is should be made into a ShopperVO". On the backend, I have a folder with a directory structure of /amf and it contains a ShopperVO.java class.
P.S This isn't exactly the setup I am working with cause I am using php, but the ideas are the same.

Mapping java classes to XML files

Hi Friends !!
Please I need your help.
Does somebody out there know any framework or API that helps me to map Java classes to XML files.
Something like:

    public int x;
    public int y;
    public int sum(){}
}to something like:
<?xml version="1.0" encoding="UTF-8"?>

How to call setter Method of ActionScript class with in a Flex Application

Hi
I have Action class as shown :
public class MyClass
private var name:String
public function get name():String {
    return _initialCount;
public function set name(name:String):void {
    name = name;
Now please let me know how can i access this Action class under my Flex Application and call the setter Method of it to set the value for the name .
For example on entering some data in a TextInput and click of a submit Button , on to the Event Listener , i want to call the set name method of my ActionScript class .
Please share your ideas on this .

Thanks Gordon for your resonse .
Say for example my Action class is like this :
public class MyClass
private var name:String
public function get name():String {
    return name;
public function set name(name:String):void {
    name = name;
This is inside the MXML
I know this way we can do it
public var myclass:MyClass = new MyClass();
myclass.name="Kiran";
Now my query is can we do in this way also ??
myclass.set name(SomeTextInput.text);
Please share your views on this , waiting for your replies .
Thanks in advance .

ActionScript class being run by mistake in Flex project

I have a Flex project where my main MXML file is set as the
one and only application file and is also set as the default file.
I also have an ActionScript class in the project that extends
Sprite. It is _not_ set as an Application file.
When I have the ActionScript class selected, if I hit run or
debug, FB3 creates a new launch configuration for it and tries to
run the AS file instead of the default application MXML file.
Needless to say, this is really annoying as it means I have
to select the main MXML file before hitting debug/run every time.
Is this a bug or feature? (Feels like a bug).
Thanks,
Aral

Hi Aral,
Can you please log it in our public bug system:
http://bugs.adobe.com/flex?
It'd be great if you can provide more info to the bug e.g.
reproducible steps, platform, FB version (Plugin or Standalone).
thanks,
Sharon

Flex Gumbo - Library Path "Include all classes" includes ActionScript Files

I've added an "Actionscript File", i.e. a File with no package/class that is included in an actionscript class.
In FlexBuilder 3, since there was no option to include all classes, I could optionally choose actionscript files.
So, Make Flashbuilder's "include all classes" option to not include Actionscript Files by default.

I opened a bug on jira.

Blaze DS - Mapping java object into another java application

Good afternoon,
I realized a Client-Server application. Server is Java-based. Client is Flex. Server services are accessible through Blaze DS.
Now I have some Java clients that need to access server services. Blaze DS permits to do it simply but I don't know how to map java objects as I do using [RemoteClass(alias.....)] construct at Actionscript side.
For example, server sends a MyObjectType and client receives an ASObject.
Is there a way to map java MyObjectType automatically at destination?
Thank you for help and sorry for poor english.
Regards, Francesco

xstream will convert any given java object to xml. Not sure what support it offers for schemas.

Converting MXML Components to ActionScript Classes

I'm in the process of converting most (if not all) of my MXML
components to Action Script classes. I've found this is easy, and
doesn't require a lot of extra code when extending a simple
container or control. However, several of my MXML components have
several nested containers and controls - i.e. a component that
contains several Labels, a ComboBox, a TextInput, a Button, and a
DataGrid, plus several other containers needed for layout. To code
the layout of all these containers and controls using MXML, it uses
about 16 lines of code. To code the layout in ActionScript, it
takes about 50+ lines of code (see attached).
I'm just wondering if there are any best practices for
creating ActionScript classes that include several (or even A LOT
OF) containers and controls. It's very easy to layout in MXML, and
is more visibly pleasing to look at and understand, but I feel it
is best practice to code components as ActionScript classes. I know
I should be using MVC, but it's a little late to rewrite the entire
application now.
Any thoughts?

I can't specifically speak to how to write layout code in
ActionScript, but you can look at the generated code that Flex
creates to get an idea of how Flex does it. When you compile an
app, the Flex compiler takes your MXML input and converts it to
ActionScript classes before compiling the entire set of classes
into a SWF. Because of this, you can look at the interim
ActionScript code.
You do this by setting the keep-generated-actionscript
compiler option to true and looking in the /generated directory.

How to set an actionscript class runnable + some question?

Dear all,
i am new to actionscript (Flex 3).
i am from java camp and i want to achive some java-style functionality in actionscript,and hope you can help me:
1. how to set an actionscript class runnable??
      in java, i just add a "public static void main(String[] args)" method which will be the program entry point. (IDE, right click the class and click run)
      i can't set a plain, ordinary actionscript runnable in flex builder.
      To test the class, i have to create an mxml (which in turn invoke the testing class) and it be runnable in the flex builder 3.
      any other way to ease the testing?
   2. it there any good 3rd party library for datatype conversion ? (e.g. string <> date, the build-in DateFormatter don't accept milliseconds)...
       it seems actionscript come with limited such kind of utility function
   3. in a custom mxml component, which contains several controls (say testboxes, comboboxes)...etc,
       for information hiding/prevent others to change the child controls in the custom component, how can i hide the child control, not allow
       other code to access the child by "Component.textbox1"....any scope modifier, e.g. protected, private...etc in mxml?
   thank you.
ppk luk

Hi Alex,
for question 3:
i just wondering if it is ok or not for better code/validation.....(and it follow the good
information hiding principle?)
if i write the component in actionscript only, i can set the child control with scope modifier
'private' or 'protected'..so that the component user can't just use the dot syntax to gain
access to the child control,
e.g. MyComponent.childControlTextInputBox.value = "A";...
i want to force user to use MyComponent.setInputBoxValue("A")...
(e.g. in this method, i can do some checking/validate before passing to the textbox)
this can enforce the data consistency in my custom UI component...
there is no way to achieve the same effect in MXML?
(e..g <mx:TextInput id="privateChildControl" accessScope="private" .../>)
thank you..

Mapping java.util.hashtable

Hello all
I have a requirement of mapping java.util.hashtable to Oracle9i database. I read on the application developers guide that this type can not be mapped through the Workbench GUI and you need to write code for it.
I followed the example code as below
DirectMapMapping directMapMapping = new DirectMapMapping();
directMapMapping.setAttributeName("..");
directMapMapping.setReferenceTableName("..");
directMapMapping.setReferenceKeyFieldName("..");
directMapMapping.setDirectKeyFieldName("..");
directMapMapping.setDirectFieldName("..");
directMapMapping.setKeyClass(String.class);
directMapMapping.setValueClass(Integer.class);
descriptor.addMapping(directMapMapping);
The insertion to the database went very well but while retriving the data from the database i am getting the following error.
Exception Description: Trying to set value [[DatabaseRow(
     DUMMYTABLE.KEYVALUE => 100
     KEYNAME => 1), DatabaseRow(
     DUMMYTABLE.KEYVALUE => 200
     KEYNAME => 2)]] for instance variable [dummyTable] of type [java.util.Hashtable] in the object. The specified object is not an instance of the class or interface declaring the underlying field, or an unwrapping conversion has failed.
If any one has any idea, please let me know.
Thanks in Advance

Which version/patch is this running? I don't know of any specific bugs to this, but there have been a couple of minor seemingly-unrelated fixes to DirectMapMapping, but sometimes they're more related than you think.
The exception is saying the types aren't matching up. You are 100% sure the attribute you're mapping to is a java.util.Hashtable? It shouldn't be necessary, but you might want to call directMapMapping.useMapClass(java.util.Hashtable.class);

Is it possible to use mx.controls in ActionScript class?

I am very new to Flex, with a very small amount of experience in ActionScript so forgive me if the answer to this is obvious. I've tried searching and haven't found a conclusive solution to my problem.
I have a Flex project that I am building in Flex Builder 3. The main application is in mxml, but most of the classes I'm using are in ActionScript.
The general purpose of the application is to create a flowchart that accepts certain inputs on the elements in the charts. The chart components are all ActionScript classes. I am attempting to add a combobox to a component, but despite not getting any errors or warnings I can't get the combobox to show up.
Here's a simplified version of the code within the class (I've left out the stuff that doesn't directly relate to my issue):
    import mx.controls.ComboBox;
          newComboBox = new ComboBox();
          newComboBox.initialized = true;
          newComboBox.alpha = 1;
          newComboBox.dataProvider = valueArray;
          newComboBox.x = 5;
          newComboBox.y = -5;
          newComboBox.height = 20;
          newComboBox.width = width - 60;
          newComboBox.visible = true;
          addChild(newComboBox);

Just realized I hadn't thanked anyone for the suggestions yet. I appreciate it.
Srirangan wrote:
Few points I can think of:
1. Try without the ".initialized = true;" property being set
2. Check if the x & y property values for the ComboBox are valid
3. Check if any styles are being applied that set the top, right, bottom or left properties thru CSS
Removing (or alternately adding) the ".initialized = true" doesn't make a difference. It was actually a last ditch effort to try to make it draw it and wasn't meant to stay in the code.
The x and y property values are valid as far as I know. The code for the positioning and sizing of the combobox was taken from the textfield below which I ended up moving down when I decided to add the combobox. The textfield has always drawn correctly.
I looked through the CSS and it doesn't appear to set top, right, bottom or left anywhere. The only CSS in the project is from the Degrafa library that I'm using to draw components.

What's the val of the variable width?
Width is set to 150, which is the width of the Constant component.

can you show the hierarchy of your flowchart component
I'm not 100% sure this is what you mean, but it's:

and just for reference the component's being drawn onto:
UIComponent > Surface (Degrafa class) > SurfaceComponent

Map java.sql.Timestamp to JDBC-MySQL TIMESTAMP?

Java provides the java.sql.Timestamp class specifically to be able to make
use of the greater-accuracy timestamps provided in JDBC and underlying
datastores. Is there a way to set up a Kodo mapping file such that a
persistent class with a java.sql.Timestamp field, has this field map to a
TIMESTAMP field in the underlying database table?
Thanks,
-- Bryan

Yes, with a custom field mapping. See the example of a custom field
mapping for java.sql.Date in samples/ormapping. A mapping for timestamp
would be almost exactly the same.

as in the above code
<mx:request xmlns="">

<bookName>{txtBookName.text}</bookName>
<category>{txtCategory.text}</category>
</isbnSearchRequest>
</mx:request>
I created an actionscript class
package com.xxxx.com
public class simpleTest
//Instance Variables
private var bookName:String;
private var category:String;
public function simpleTest()
function getBookName():String {
return bookName;
function setBookName(bookName:String):Void {
this.bookName = bookName;
function getCategory():String {
return category;
function setCategory(category:String):Void {
this.category = category;
How can I use this ActionScript class to use in
<bookName>{txtBookName.text}</bookName>.
Thanks in advance.

I think you're close to achieving what you want... first I
would change your getter and setter methods just a bit to make them
properties. Second add the [Bindable] meta tag in front of one of
each of the group of properties (i.e. you don't need it in front of
both the get and set method, just one of them).
i.e.
[Bindable]
public function get category():String {
return category;
public function set category(value:String):void{
category = value;
then in your mxml you can "bind" to each property you've
defined in the class. so if you create a new instance of your
simpleTest class called "test" you could do the following:
<mx:Label text="{test.category}" />
