How do I send a DateTime or some sort of timestamp from PHP to Java using Hessian binary remoting protocol?

Question

There is a Java service that I need to invoke from PHP that looks something like this:

getProductsForMode(java.util.Calendar date, int modeId)

I'm having trouble mapping my PHP date class to the java.util.Calendar class. I've tried a couple different approaches, all to no avail:

Approach #1 (wrapping DateTime object in a CalendarHandle that gets mapped to Java's CalendarHandle):

class CalendarHandle
{
  public $type;
  public $date;

  function __construct($date=null)
  {
    $this->date = $date;
  }
}

$this->hessianClient = new HessianClient(_HESSIAN_ENDPOINT, $hessianOptions);
$config = &HessianConfig::globalConfig();
$config->typeMap->mapRemoteType('com.caucho.hessian.io.CalendarHandle', 'CalendarHandle');

$time = new CalendarHandle(new DateTime($dateEvaluated));
$products = $this->hessianClient->getProductsForMode($time, 1234);

Error:

[06-Jul-2011 11:16:52] PHP Fatal error: Uncaught exception 'HttpError' with message 'HttpError: Malformed HTTP header' in /Users/jordanb/Sites/proposal-framework/trunk/plugins/srHessianClientPlugin/hessianphp/Http.php:265

Approach #2: Mapping DateTime to java.util.Calendar

$this->hessianClient = new HessianClient(_HESSIAN_ENDPOINT, $hessianOptions);
$config = &HessianConfig::globalConfig();
$config->typeMap->mapRemoteType('java.util.Calendar', 'DateTime');

$time = new DateTime($dateEvaluated);
$products = $this->hessianClient->getProductsForMode($time, 1234);

Error:

[06-Jul-2011 11:28:50] PHP Fatal error: Uncaught exception 'HessianError' with message 'Hessian Parser, Malformed reply: expected r' in /Users/jordanb/Sites/proposal-framework/trunk/plugins/srHessianClientPlugin/hessianphp/Protocol.php:350

Has anyone had success sending a DateTime or some sort of timestamp from PHP to Java using Hessian? Thanks in advance!

Would it be practical to just use the php time() function (which returns an int and send this as a long to Java? In Java you could just pass the long to new Date(long Date).

Although not ideal, this is probably the best solution. Thanks – Jordan Brown Jul 06 '11 at 20:19

Use unix timestamp. That's the best bet.

PHP:

$ts = time();

Pass $ts to java in someway.

Java:

long ts = getTimeFromPhp();
Date dt = new Date(ts);

Or you can use Calendar:

Calendar cal = Calendar.getInstance();
cal.setTimeInMillis(ts);
