      I use xmldbms version 2.0 alpha which is downloaded from cvs.
      when transferring data from database from XML,BigDecimal is converted to Long or Double.
      and there is a error in converted to Long. and I add one condition:
      org.xmlmiddleware.conversions.ConverBigDecimal line133
      there is two condition before and i add b.subtract(new BigDecimal(b.longValue() )).doubleValue() !=0) :

      if((b.compareTo(MAX_LONG) == 1) || (b.compareTo(MIN_LONG) == -1)||b.subtract(new BigDecimal(b.longValue() )).doubleValue() !=0)

      so it works well.
