We have a large XML message with repeating structure.
I am trying to split the XML into smaller XMLs in Java compute Node.
I am unable to find any sample using Java.
Can anybody help on this.

We have chosen Java compute node as we have some stored procdure calls
with arraylits over ESQL compute node.

If you're using ESQL compute node why not split the XML by using references in ESQL?

Put an ESQL-Node in front of your Java Node

...and within you ESQL-Code do some PROPAGES and maybe also RETURN FASE at the end (instead of RETURN TRUE).

Probably you can also use DETACH in combination with PROPAGATE, but I am not sure with that.

Hi,

I think you should try partial parsing / processing --which is built in functionality- the large message. Look from samples gallery "Large Messaging sample". I think that the same processing --as in the sample with esql-- is possible with java.

I think MbElement is your friend in manipulating message with java. http://publib.boulder.ibm.com/infocenter/wbihelp/v6rxmx/index.jsp?topic=%2Fcom.ibm.etools.mft.broker.doc%2Fcom%2Fibm%2Fbroker%2Fplugin%2FMbElement.html

And check JavaComputeNodeSampleFlowProject/JavaComputeTransformNoXPathFlow
from samples gallery for guiding you the beginning of the exploration into world of java programming with broker.
