In Axis 1.4 (not Axis2) an element is omitted from the request if the value is
set to null and it is has the nillable="true" and minOccurs="0" attributes set
in the schema.
Here is the location where I think things are going wrong:
org.apache.axis.encoding.ser.BeanSerializer.serialize(QName name, Attributes
attributes, Object value, SerializationContext context)
Here is the chunk of code:
// Serialize each property
for (int i=0; i<propertyDescriptor.length; i++) {
<SNIP>
// Read the value from the property
if (propertyDescriptor[i].isReadable()) {
if (itemQName != null ||
(!propertyDescriptor[i].isIndexed() && !isArray)) {
// Normal case: serialize the value
Object propValue =
propertyDescriptor[i].get(value);
if (propValue == null) {
// an element cannot be null if nillable property is
set to
// "false" and the element cannot be omitted
if (!isNillable && !isOmittable) {
if (Number.class.isAssignableFrom(javaType)) {
// If we have a null and it's a number,
though,
// we might turn it into the appropriate
kind of 0.
// TODO : Should be caching these
constructors?
try {
Constructor constructor =
javaType.getConstructor(
SimpleDeserializer.STRING_CLASS);
propValue =
constructor.newInstance(ZERO_ARGS);
} catch (Exception e) {
// If anything goes wrong here, oh
well we tried.
}
}
if (propValue == null) {
throw new IOException(
Messages.getMessage(
"nullNonNillableElement",
propName));
}
}
// if meta data says minOccurs=0, then we can skip
// it if its value is null and we aren't doing SOAP
// encoding.
if (isOmittable && !isEncoded) { // *** HERE IS THE
PROBLEM I THINK ***
continue;
}
}
<SNIP>
} else {
<SNIP>
}
}
}
I snipped some sections of the code to make it easier to see where I think
things are going wrong.
How can I have an element that is nullable but omittable, but I want to
explicitly set it to null. I don't know that I want this to be a global change
either.
If it helps, I did modify the soap stub generator to generate an
<attrib_name>Specified Boolean flag in the soap stubs. This flag is set to true
when the attribute is set:
public class Street_addr implements java.io.Serializable,
api.rightnow.com.RNOWISpecified {
boolean UseSpecified; // Flag to indicate that we are serializing
private java.lang.String city;
private boolean citySpecified;
private java.lang.Integer country_id;
private boolean country_idSpecified;
private java.lang.String postal_code;
private boolean postal_codeSpecified;
private java.lang.Integer prov_id;
private boolean prov_idSpecified;
private java.lang.String street;
private boolean streetSpecified;
public Street_addr() {
}
<SNIP>
/**
* Gets the prov_id value for this Street_addr.
*
* @return prov_id
*/
public java.lang.Integer getProv_id() {
if (UseSpecified && !prov_idSpecified)
return null;
return prov_id;
}
/**
* Sets the prov_id value for this Street_addr.
*
* @param prov_id
*/
public void setProv_id(java.lang.Integer pprov_id) {
prov_idSpecified=true;
this.prov_id = pprov_id;
}
So I could possibly check to see if this flag is set to true before omitting
the element.
Thoughts?
