You want to return a typed object from a J2EE back end.
Use the third-party ASTranslator
class to
convert a JavaBean object to an ASObject
, and
return the ASObject
.
For details on obtaining ASTranslator, see Recipe 20.17.
Once you have ASTranslator included in your web application, you can
use the toActionScript( )
method of an
ASTranslator
object to convert a JavaBean object
into an ASObject
that can be returned to Flash.
Here is an example of a Java method that creates a JavaBean object,
converts it into an ASObject
, and returns the
ASObject
:
public flashgateway.io.ASObject getTypedObject( ) { // Create aMyClass
JavaBean object. See Recipe 20.14 for theMyClass
code. MyClass myCls = new MyClass( ); // Set the properties of the object. myCls.setA("eh"); myCls.setB("bee"); // Create anASTranslator
object. com.carbonfive.flash.ASTranslator ast = new com.carbonfive.flash.ASTranslator( ); // Convert theMyClass
object to anASObject
. flashgateway.io.ASObject aso = ast.toActionScript(myCls); // Return theASObject
. return aso; }
Here is an example ActionScript snippet that handles the returned
ASObject
:
function MyClass(a, b) { this.a = a; this.b = b; } MyClass.prototype.a; MyClass.prototype.b; // Add a method that just writes all the properties to the Output window. This // example illustrates that theASObject
is correctly converted into aMyClass
object // when returned to Flash. MyClass.prototype.traceProperties = function ...
