Calling Enterprise JavaBeans (EJBs) from Flash 129
mx.remoting.debug.NetDebug.initialize();
//…
function runExample()
{
var SampleLoanHome:Service = new Service(
"http://localhost:8300/flashservices/gateway",
null,
"SampleLoanEjbHome",
null,
null);
var pc:PendingCall = SampleLoanHome.create();
pc.responder = new RelayResponder(this, "create_Result", "create_Fault");
}
function create_Result( re:ResultEvent )
{
flashStatelessEJB = re.result;
calculate();
}
function create_Fault( fe:FaultEvent )
{
mx.remoting.debug.NetDebug.trace({level:"None", message:"There was a
problem" + fe.fault.faultstring});
}
function calculate()
{
var cal_pc:PendingCall = flashStatelessEJB.calculate( (number
(principalInput.text)), (number (monthsInput.text)), (number
(rateInput.text)) );
cal_pc.responder = new RelayResponder(this, "calculate_Result",
"calculate_Fault");
}
To handle the function results, you use a result handler function like the following:
function calculate_Result (re:ResultEvent)
{
payOutput.text = re.result;
}
function calculate_Fault( fe:FaultEvent )
{
mx.remoting.debug.NetDebug.trace({level:"None", message:"There was a
problem" + fe.fault.faultstring});
}
For more information, see “Handling function results in ActionScript” on page 137.
Looking at a Flash application that calls an EJB
The following sections illustrate the three pieces required to call an EJB from Flash Remoting:
• “Looking at the EJB code” on page 130
• “Looking at the user interface for the EJB” on page 130
• “Looking at the ActionScript code that calls the EJB” on page 131
