Note: You cannot call constructors with Flash Remoting. Use the default constructor.
In ActionScript, the following
import mx.remoting.*;
import mx.services.Log;
import mx.rpc.*;
// Connect to service and create service object
var javaService:Service = new Service(
"http://localhost/flashservices/gateway",
null,
utils.UIComponents",
null,
null );
// Call the service sayHello() method
var pc:PendingCall = javaService.sayHello();
// Tell the service what methods handle result and fault conditions
pc.responder = new RelayResponder( this, "sayHello_Result", "sayHello_Fault" );
function sayHello_Result(re:ResultEvent)
{
// Display successful result
trace("Result is: " + re.result);
}
function sayHello_Fault(fe:FaultEvent)
{
// Display fault returned from service
trace("Error is: " + fe.fault.description);
}
Note: For more information about using Java objects with ColdFusion, see
Handling errors with ColdFusion and Flash
To help with debugging, use
to Flash Player. For example, the ColdFusion page, causeError.cfm, contains the code:
<cftry>
<cfset dev = Val(0)>
<cfset Flash.Result = (1 / dev)>
<cfcatch type = "any">
<cfthrow message = "An error occurred in this service: #cfcatch.message#">
</cfcatch>
</cftry>
call runs the
javaService
and tags in your ColdFusion page or component to return error messages
cftry cfcatch
