Data syndication using MDM Java API

[Former Member]

Hello,

Did someone succeed in syndicating data using the MDM Java API (Class SyndicatePortCommand) ?

The procedure in the javadoc isn't clear and there is no example for testing syndication through the Java API.

I wrote a class SyndicatePortExample adapted from the example in the javadoc.

So far, I have no success, when I call the method SyndicatePortCommand.execute, no exceptions is thrown but when I use getPortDataFilesCommand, nothing is retrieved?!

Did I miss something?

Greetings

Hi Yang,

Did you got the solution for executing Syndication through Java MDM API?? If so can you please let us know where the problem was.

Basically i am trying to syndicate records by MDM API. But i dont find a proper example to do this.

Thanks,

Raags

Thanks for the tips, I checked my source code and I duplicated some functionalities from the example but still no syndicated data...

I also ran the example from the howto and still no syndicated data...

I will check the logs in the syndication server. Maybe I'll get a clue...

Hi, Yan

Syndication through Java API is asynchronous. Also Syndication Server must be running.

Something curious happen here. If you syndicate a port or syndicate a particular record when MDSS is stopped, those syndications request are enqueued somewhere. When MDSS starts, those requested are then executed.

You may also use EventDispatcher class in order to be notified when a Syndication Event occurs.

Good luck

Hello,

Do you have any example of how to use this class? As you can expect, mdss was running, data in the table, the port actually works, manually and automatically, so I expected the class SyndicatePortCommand to work...

Unfortunately I have no documents or example on how to use syndication with the java API (only a few lines in the javadoc!!)

So I am making several experiments without success...

PS: Before, we planned to use the CLI SyndicatorBatch.exe wrapped in a java class but since it has been removed...

The following code syndicate specific records with the class AddSyndicationRecordIdsCommand but i would expect that SyndicatePortCommand works similar

String portCode = "PORT_CODE";
String filePrefix = "SomeFilePrefix";
SimpleConnection connection;
String session;
PortProperties[] portList;
RecordId[] recordIds;
...

GetPortListCommand getPortsCmd = new GetPortListCommand(connection);
getPortsCmd.setSession(session);
getPortsCmd.execute();		
portList = getPortsCmd.getPorts();

//   Search a specific portCode
PortProperties port = null;
for (int i=0; i < portList.length; i++) {
	if (portCode.equals(portList<i>.getCode())) {
		port = portList<i>;
		break;
	}
}
if (port == null) {
	throw new RuntimeException("Can't syndicate, port doesn't exist" );
}

//   Call sindication
AddSyndicationRecordIdsCommand addSyndRecordCmd = new AddSyndicationRecordIdsCommand(connection);
addSyndRecordCmd.setSession(session);
addSyndRecordCmd.setFilePrefix(filePrefix);
addSyndRecordCmd.setPortId(port.getId());
addSyndRecordCmd.setRemoteSystemId(port.getRemoteSystemId());
addSyndRecordCmd.setRecordIds(recordIds);
addSyndRecordCmd.execute();
