Custom Snap for h2 database

Hi,

I have created a custom snap to connect to h2 database and its working except Ultra.So I added lineage code like below.

	      Map<String, Object> data = new LinkedHashMap<>();
		data.put("Value", result);
		Document seed = documentUtility.newDocument(data);
	         Document newDocumentWithLineage = documentUtility.newDocument(seed,originalDocument);
		outputViews.write(seed,originalDocument);

It is giving output in ultra but the problem is,it is iterating for 5 times as its not getting ackowledge message from JMS que.Attaching the stack trace.Please advice me on this issue.

Thanks and Regards,
Ashlam

    Can you try removing this line:

    Document newDocumentWithLineage = documentUtility.newDocument(seed,originalDocument);

    When you write to the output view with the original document, as in the following line, it should take care of establishing the lineage:

    outputViews.write(seed,originalDocument);
