Xs:time to DATE ConversionException

Question

Hi,
I'm using toplink through a wizard as part of JDeveloper and BPEL.
I've this exception when I try and insert a record, the context is I'm trying to insert a time from an xml document into a date field in my oracle 9.2 database.
WSIF JCA Execute of operation 'insert' failed due to: DBWriteInteractionSpec Execute Failed Exception. insert failed. Descriptor name: [####]. ; nested exception is: ORABPEL-11616 DBWriteInteractionSpec Execute Failed Exception. insert failed. Descriptor name: [####]. Caused by Exception [TOPLINK-3001] (OracleAS TopLink - 10g (9.0.4.5) (Build 040930)): oracle.toplink.exceptions.ConversionException Exception Description: The object [xs:datetime 17:10:08+00:00], of class [class java.lang.String], could not be converted to [class java.util.Calendar]. Internal Exception: java.lang.StringIndexOutOfBoundsException: String index out of range: 19.
This looks like a bug to me, so has anyone a work-around? Do I need to create my own converter? Any help gratefully received.
