New Features Added to Adobe ActionScript API Reference (ASDoc)

Use the ActionScript® 3.0 Reference for the Adobe® Flash® Platform as the API reference for many Adobe products, including Flash Player, AIR, and Flex. The new release of the ActionScript Reference ( contains several new features:

  • Support for a quick search added to the Packages and Classes lists.The quick search lets you filter the content of the Packages and Classes lists as you type. This feature is not supported on IE 7 and IE 8.
  • When displaying all classes in the Classes list, selecting a class name in the list continues to display all classes.In the previous release, selecting a class name in the Classes list while displaying all classes changed the Classes list to display only the classes in the package of the selected class.
  • Added a Home link to the top of all pages.The Home link lets you navigate back to the index.html page from anywhere in the reference.
  • Fixes for issues associated with localization and translation.

LiveCycle Data Services 3 Beta Available

LiveCycle Data Service 3 Beta 1 is now available on Adobe Labs.

The new model-driven development features in LiveCycle Data Services 3 offer a huge leap in productivity and ease-of-use for end-to-end applications. You start an application by creating a data model (a simple XML file) in the new “Modeler” editor that plugs into Flash Builder. From that model, you automatically generate data access logic on the server and Flex client code for working with the server code.

You can even generate much of a model by dragging existing SQL database tables into the Modeler editor. When you save the model, client code is automatically generated. When you deploy the model to the server, a fully functional Data Management Service destination is automatically generated on the LiveCycle Data Services server. You can support even the most advanced Data Management Service features just by creating and deploying a model.

Using Flash Builder with LiveCycle Data Services, you can now build simple or complex data-driven applications without writing any server-side code or configuration files. You can also take full advantage of the new Flash Builder 4 features for building the client side of data-driven applications.

We would love to get your feedback on this release and the documentation. To learn more:

Calling remoting destinations from Flash or Java applications

The legacy NetConnection API of Flash Player provides a way to call remoting destinations from a standard (non-Flex) Flash application or from ActionScript in a Flex application if desired. The new Java AMF Client in BlazeDS gives you a Java API patterned on the NetConnection API but for calling remoting destinations from a Java application. You can use either of these APIs with BlazeDS, LiveCycle Data Services, or third-party remoting implementations.

Call a remoting destination from a Flash application

You can use the Flash Player API to call a BlazeDS remoting destination from a Flash application. You use the NetConnection.connection() method to connect to a destination and the method to call the service.
The following MXML code example shows this legacy way of making remoting object calls with NetConnection instead of RemoteObject:

<?xml version="1.0"?>
<mx:Application xmlns:mx="" width="100%" height="100%"

<mx:Panel id="mainPanel" height="100%" width="100%">
<mx:Label text="Enter a text for the server to echo"/>
<mx:TextInput id="ti" text="Hello World!"/>
<mx:Button label="Send" click="echo()"/>
<mx:Button label="Clear" click='ta.text = ""'/>
<mx:TextArea id="ta" width="100%" height="100%"/>
private var nc:NetConnection

private function creationCompleteHandler():void
nc = new NetConnection();
nc.objectEncoding = ObjectEncoding.AMF0;
nc.connect("http://[server]:[port]/yourapp/messagebroker/amf" );
private function echo():void
{ "remoting_AMF.echo", new Responder( resultHandler, faultHandler ), ti.text );
private function resultHandler(result:Object):void
ta.text += "Server responded: "+ result + "\n";
private function faultHandler(fault:Object):void
ta.text += "Received fault: " + fault + "\n";

Call a remoting destination from a Java application

The Java AMF Client is new Java client API in the BlazeDS flex-messaging-core.jar file that makes it simple to work with remoting destinations from a Java application. The Java AMF Client is similar to the Flash Player API, but uses typical Java coding style rather than ActionScript coding style.

The Java AMF Client classes are in the* package in the flex-messaging-amf.jar file. The primary class of the Java AMF Client is the AMFConnection class. You connect to remote URLs with the AMFConnection.connect() method and call the service with the method. You catch ClientStatusException and ServerStatusException exceptions when there are errors.
Here’s a simple example of how you can use AMFConnection to call a Remoting Service destination from a method in a Java class:

public void callRemoting()
// Create the AMF connection.
AMFConnection amfConnection = new AMFConnection();

// Connect to the remote url.
String url = "http://[server]:[port]/yourapp/messagebroker/amf";
catch (ClientStatusException cse)

// Make a remoting call and retrieve the result.
Object result ="remoting_AMF.echo", "echo me1");
catch (ClientStatusException cse)
catch (ServerStatusException sse)
// Close the connection.

The Java AMF Client automatically handles cookies similarly to the way in which web browsers do, so there is no need for custom cookie handling.

Building Adobe LiveCycle Data Services ES Beta 2 Applications

Adobe LiveCycle Data Services ES Beta 2 applications consist of two parts: client-side code and server-side code. Client-side code is a Flex application written in MXML and ActionScript and deployed as a SWF file. Server-side code is written in Java and deployed as Java class files or Java Archive (JAR) files. You can develop Adobe LiveCycle Data Services ES applications in Flex Builder, or in your own IDE. This article describes how to set up your development environment to compile, debug, and deploy LiveCycle Data Services ES applications.

Adding Java Development Tools to Flex Builder Standalone

Many Flex, Adobe AIR, Adobe BlazeDS, and Adobe LiveCycle ES developers choose to use the Eclipse plug-in configuration of Flex Builder so that they can develop Java code in the same IDE that they use to develop the MXML and ActionScript code. While the standalone version of Flex Builder does not contain tools to edit Java code by default, you can install them as Eclipse plugins. That lets you use the standalone version of Flex Builder to edit Java code.

To install the Java development tools in the standalone version of Flex Builder:

1. Use the Help > Software Updates > Find and Install menu command to open the Install/Update dialog box

2. Select Search for new features to install.

3. Click Next.

4. In the results, choose Europa Discovery Site.

5. Click Finish.

6. Select the Java Development package to install.

7. Click Next.

8. Accept the license.

9. Click Finish.

Note: You might be prompted to install additional plugins required by the Java Development package.

To change perspective:

1. Use the Window > Perspective > Other to access all perspectives.

You can also click the Open Perspective button in the upper-right corner of the workbench window, then select a perspective from the pop-up menu.

2. Select Java from the list of perspectives.

Measuring Message Processing Performance in BlazeDS

One place to examine application performance is in the message processing part of the application. To help you gather this performance information in BlazeDS, you can enable the gathering of message timing and sizing data.

When enabled, information regarding message size, server processing time, and network travel time is available to the client that pushed a message to the server, to a client that received a pushed message from the server, or to a client that received an acknowledge message from the server in response a pushed message. A subset of this information is also available for access on the server.
