Re: Plz. solve exception in sample com.witneybank.olb.ReadPurchaseOrder
Posted by kelvin goodson <ke...@apache.org>.
In adapting the sample you have commented out the loading of the xml
schema metadata. In so doing you have altered the dynamics of the
sample to use SDOs generic XML behaviour. This means that as the SDO
runtime reads your document it will build up the loosest form of
metadata it can on the fly, in order that it does not preclude later
content of document. It will therefore, when it first sees a shipTo
element, model that as an isMany feature. I can't recall exactly how
this goes now without digging back, it may also be that the document
is modeled as an sdo Sequence (there are samples for Sequences if so).
I suggest you either reintroduce the loading of the schema (if
necessary, adapted to match your modified document), or take a look at
the samples for generic XML and sequences. I hope this lets you
advance, if not please post back.
Kelvin.
