Calling server-side ActionScript from Flash (JRun only) 135
Getting a reference to an MBean in ActionScript
Before calling the methods of an MBean from ActionScript, you must get a reference to an
MBean.
To get a reference to an MBean:
1. Import the Flash Remoting files:
import mx.remoting.Service;
2. Connect to the Flash Remoting gateway and get a reference to the MBean object. You must
provide the name of the JMX object under which the MBean is registered, as shown in the
following example:
jrunDeployerMBean = new Service(
"http://localhost/flashservices/gateway"),
null,
"DefaultDomain:service = DeployerService",
null,
null)
Note: There are several other ways to specify the gateway URL. For more information, see
Chapter 2, “Using Flash Remoting ActionScript,” on page 29.
Invoking MBean methods in ActionScript
After you have a reference to an MBean, you can use ActionScript functions to invoke its public
methods. For example, you could use the following ActionScript code to invoke the
getEARs()
method of the jrunDeployerMBean MBean to get a list of JMX object names for deployed
enterprise applications:
function getEARs():Void
{
pc:mx.remoting.PendingCall = jrunDeployerMBean.getEARs();
pc.responder = new RelayResponder( this, "getEARs_Result",
"onCategoryFault" );
// etc.
}
To handle the function results, you use a result handler function like the following:
function getEARs_Result(result:mx.rpc.ResultEvent):Void
{
numDeployed.text = result.length;
}
For more information, see “Handling function results in ActionScript” on page 137.
Calling server-side ActionScript from Flash (JRun only)
This section describes how to call a server-side ActionScript file from Flash using Flash Remoting.
By using server-side ActionScript, Flash developers can create server-side code without learning
Java. You can also call server-side Java objects from server-side ActionScript. JRun uses the
Mozilla Rhino JavaScript engine to support server-side ActionScript; for more information about
calling Java objects with Rhino, go to www.mozilla.org/rhino/scriptjava.html.
