Application Server Connectivity 95

3 Create a global object to hold the recordset.

// An object to hold your service and recordset

gFoo = {};

Get a reference to the foo service.

// Get a named service

gFoo.service = gRemotingGateway.getService("foo", gFoo);

Create the onResult callback, which the Flash Remoting service expects.

// Set up the onResult callback and call it bar_Result.

// The function must be named such that if you call

// xxx method on the foo service, it will result in

// xxx_Result method being called. You set the data in

// the shared object so the Flash client can display it.

gFoo.bar_Result = function(result) {

var cols = result.getColumnNames();

trace("Columns: " + cols);

gRecords.setProperty("__COLUMNS__", cols);

var reclen = result.getLength();

trace("number of records " + reclen);

for (var i = 0; i < reclen; i++) {

trace(i + "] " + result.getItemAt(i));

gRecords.setProperty(i, result.getItemAt(i));

}

In the onConnect function, accept the client’s connection.

application.onConnect = function(client) {

trace(application.name + " connect from " + client.ip);

application.acceptConnection(client);

}

Provide a prototype function that the client can call to get the records.

Client.prototype.getRecords = function() {

// Call the bar method on foo service

var result = gFoo.service.bar();

trace("gFoo.service.bar returned " + result);

}

Save the file as main.asc in a doc_rset directory under the flashcom applications directory.

Note: Save this main.asc file where you’ve chosen to store your server-side application files. For more

information see Chapter 1, “The flashcom application directory,” on page 15.

To write the ColdFusion component for this sample:

1 Using your standard editor, create a new file and add code to query the database for all records.

SELECT * FROM tblItems

</cfquery>

Save the file as bar.cfm in the foo directory under the directory where you publish all of your

ColdFusion MX files.
