HTTP to JMS issue

[Former Member]

I have created a BPM which sends HTTP request over to JMS Websphere MQ (receiver comm channel). After I send async data to the MQ, I have a transformation step which reads the correlation id. In order for this to work, I have enabled Adapter specific message attributes.

This is the code I have in my UDF (is a step after send step)

java.util.Map map = container.getTransformationParameters();

DynamicConfiguration conf = (DynamicConfiguration) container

.getTransformationParameters()

.get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);

DynamicConfigurationKey key = DynamicConfigurationKey.create(

"http://sap.com/xi/XI/System/JMS", "DCJMSCorreleationID" );

String corrId = conf.get(key);

return corrId;

I get a null value eventhough I see a corr id in the adapter monitor.

In the mapping trace, I see

<Trace level="3" type="T">Dynamic configuration is empty</Trace>

Any ideas on what I'm doing wrong here.

Thank you.

Thanks Moorthy.

I'm able to set the correlation id before send and retrieve it after send.

Sequence being

HTTP -> Transform (set corr id) -> Send JMS -> Transform (retrieve corr id)

The problem is if my communicaiton channel is down, I still can retrieve the correlation id from the dynamic config. I was hoping would get a null if the channel is down and a value if the channel is up and running.

How can I tell if the channel is down?

Thanks, Parimala

For the channel is down, you can set up Adapter alerts for this. Just like normal alert configuration.

So that person can be notified thru Alert/Email.

Unfortunately, this one object is not set up in our current CCMS monitoring and therefore I cannot get any alerts.

Do you know how I can get this to work. CCMS monitor shows alerts for IS, QRFC queues, Java components. But I don't see anything for Adapters.

I don't mind writing an EJB to check status. I see in com.sap.aii.af.monitor.api.AdapterStatus with method getStatusData()....not sure how this one works.

I appreciate any help. Thank you.
