Hi All,
Apologies If I am posting a silly question.

Would like to know whether we have something equivalent to CARDINALITY ESQL function in Java Plugin API. I did browse thro' the API documentation for classes MbElement and MbMessage without luck . Would really appreciate if somebody can direct me in achieving this functionality within JCN.

Thanks.

I guess u want to find the cardinality of particular complex element in Input message
Try using SQL statements in java like select count() from InputRoot.XML.Emp[]
(I am not sure .. this idea may work)

I guess Merecury means that you can use MBSQLStatement to run a cardinality statement.

You can also use XPath to run this count, I think. You might have to use it to get a node list, and then ask the List object for it's count.
