Subject RE: how can I turn off xsi:nil="true" element
Date Wed, 13 Mar 2002 15:38:43 GMT
Oops I fired off the note too quickly!

The actual snippet of code in BeanSerializer is:

                    // Normal case: serialize the value
                    Object propValue = propertyDescriptor[i].getReadMethod
().invoke(value,noArgs);

                    if (propValue != null)        //  <----------- Add this
line to preven serializing null values
                      context.serialize(qname,
                                      null,
                                      propValue,
                                      propertyDescriptor[i].getReadMethod
().getReturnType());

Glen is concerned about method resolution problems associated with omitted
data.

But I think Ramana's problem is with omitted properties inside a
complexType.  This is a slightly
different issue and is "easier" to address.  Currently the BeanSerializer
does not have enough
information to determine whether a field is:

   - "nillable=true" ...which dictates that a null value is passed over the
wire with xsi:nil="true"
  - or "minOccurs=0"...which dicates that  a null value is not passed over
the wire at all.

One way for you to address this problem is to provide your own
BeanSerializer that does not
serializer null values.

Here is the snippet of code in the BeanSerializer that needs to be changed.
I added a comment next to the new code.

                   // Collection of properties: serialize each one
                    int j=0;
                    while(j >= 0) {
                        Object propValue = null;
                        try {
                            propValue = propertyDescriptor[i].getReadMethod
().invoke(value,
                                                                     new
Object[] { new Integer(j) });
                            j++;
                        } catch (Exception e) {
                            j = -1;
                        }
                        if (j >= 0 &&
                           propValue != null                //  <---- This
will prevent serializing null values
              {
                            context.serialize(qname, null,
                                              propValue,

propertyDescriptor[i].getReadMethod().getReturnType());
                        }
                    }

Right now, you can't.  This would very easy to add with another option
(i.e. "OMIT_NILS"), but note that it would take more work for us to be able
to process *incoming* messages like this - we can't currently deal with
omission==null because we do all our parameter-matching by position and not
by name.  To recap: sending with omitted elements is easy, receiving with
omitted elements is hard at present.

(I'm working on stuff in my sandbox which will solve this problem among
other things, but it won't show up until post-beta)
