Hello friends,
How can I return a Data Object to the client side?
I am using the SDO_DAS_XML to create the data object but I cannot send
to the client the correct object.
I have tried this example (and a lot others):http://www.ibm.com/developerworks/web/library/ws-soa-scasdo/index.html
<?php
include "SCA/SCA.php";
/**
*
*/
class WeatherService {
/**
*/
public function getTemperature($Areas) {
$Temperatures = SCA::createDataObject('http://Weather',
'Temperatures');
$Pair = $Temperatures->createDataObject('entry');
$Pair->state = 'CA';
$Pair->temperature = 65;
$Pair = $Temperatures->createDataObject('entry');
$Pair->state = 'UT';
$Pair->temperature = 105;
$Pair = $Temperatures->createDataObject('entry');
$Pair->state = 'ND';
$Pair->temperature = -20;
return $Temperatures;
}}
?>
<?php
include "SCA/SCA.php";
$weather = SCA::getService('http://mydomain.com/SOA/Weather/
WeatherService.php');
$Areas = $weather->createDataObject('http://Weather','Areas');
$area = $Areas->createDataObject('area');
$area->state = 'CA';
$area = $Areas->createDataObject('area');
$area->state = 'UT';
$area = $Areas->createDataObject('area');
$area->state = 'ND';
$Temperatures = $weather->getTemperature($Areas);
echo "Received temperatures from Web service:<br>";
foreach($Temperatures->entry as $Pair)
echo $Pair->state . ": " . $Pair->temperature . "<br>";
?>

Can you tell me what I am doing wrong?
The next question is: How can I create a dynamic data object returning
to the client a list of some information?
Thank you guys!

Hi there

You should be able to do this and on the face of it your code looks
good. Can you tell me....

1. What was the result of running it. An error? Just no return data?
2. Did the input parameter ($Areas) get delivered successfully?
3. What version of the code you are using?

We do return complex types in some of the samples, for example, [1].
Haven't run it for a while so will have to get set up and give it a
spin to make sure it still works.

Regards

Simon
