Wow...that was easy. I figured it out...thanks for pointing me to the
serializer/deserializer:
public class DateTimeSerializer {
public static DateTime deserializeDateTime(String dateTime) throws
XmlBinderException{
DateTime date = null;
try {
date = DateTimeHelper.getDateTimeFromFormat(dateTime,
DateTime.YYYY_MM_DD);
}
catch (ParseException e) {
throw new XmlBinderException(e);
}
return date;
}
public static String serializeDateTime(DateTime dateTime) {
return dateTime.getDateTimeFormat(DateTime.YYYY_MM_DD);
}
}
With binding.xml:
<binding direction="both" forwards="false" package="foo.jibx"
value-style="element" >
<format type="foo.DateTime"
serializer="foo.jibx.DateTimeSerializer.serializeDateTime"
deserializer="foo.jibx.DateTimeSerializer.deserializeDateTime"/>
<mapping class="foo.DiagnosisTO" name="Diagnosis">
<value name="codeType" field="codeType"/>
<value name="code" field="code"/>
<value field="date" name="date"/>
</mapping>
</binding>
This successfully now converts between XML and Java
Object....AWESOME!!!!!!! This was soooooo easy.
Thanks for your help!!!!

This is a segment of my XML that uses a custom class:
<Diagnosis>
<codeType>123</codeType>
<code>Blah</code>
<date>2005-12-04</date>
</Diagnosis>
The date element is really just the CCYY-MM-DD (required format
for xs:date) and needs to be converted into:
public class DiagnosisTO extends BaseTO implements ImageTO {
private DateTime date;
private String code;
private String codeType;
.........
The DateTime object just does the general date comparison,
conversion from calendar, and so on. So I can create a DateTime
object with the following constructor:
new DateTime(Calendar c) or new DateTime(TimeZone tz) or new
DateTime(String dbdate) or others
And I convert from DateTime into date String (in CCYY-MM-DD format
for xs:date):
dateTime.getDateTimeFormat(DateTime.YYYY_MM_DD)
In JAXB (just as a sample, I did the following:
public class DateTimeDatatypeConverter {
/**
* @param value param
*
* @return returned
*/
public static DateTime parseStringToDateTime(String value) {
return new DateTime(DatatypeConverter.parseDate(value));
}
/**
* @param value param
*
* @return returned
*/
public static String printDateTimeToString(DateTime value) {
return
DatatypeConverter.printString(value.getDateTimeFormat(DateTime.YYYY_MM_DD));
}
}
My Type Safe Enumerations work the same way, here is a code snippet:
<PatientConditionInformation>
<conditionCategory>77</conditionCategory>
<conditionResponse>Y</conditionResponse>
<conditionIndicator>01</conditionIndicator>
</PatientConditionInformation>
All these subelements refer to a value in the TypeSafeEnumeration.
Class example:
public class PatientConditionCategoryType extends
AbstractTypeSafeEnumeration {
public static final PatientConditionCategoryType
AMBULANCE_CERT = new PatientConditionCategoryType("07", "Ambulance
Certification");
public static final PatientConditionCategoryType
OXYGEN_THERAPY_CERT = new PatientConditionCategoryType("11",
"Oxygen Therapy Certification");
public static final PatientConditionCategoryType MENTAL_STATUS
= new PatientConditionCategoryType("77", "Mental Status");
With the pairing being (value, displayValue).
JAXB Converter example:
public class PatientConditionCategoryDatatypeConverter {
/**
* @param value param
*
* @return returned
*/
public static PatientConditionCategoryType
parseStringToPatientConditionCategory(String value) {
return
PatientConditionCategoryType.getType(DatatypeConverter.parseString(value));
}
/**
* @param value param
*
* @return returned
*/
public static String
printPatientConditionCategoryToString(PatientConditionCategoryType
value) {
return DatatypeConverter.printString(value.getValue());
}
}
Sorry for the overload of information....I am just totally stoked
to get this working and very much appreciate your insight.
Thanks,
Jay

I am reading how to do this in JiBX, but I am a little
confused on the

(created through the binding generator):
I've built a some of these as well, so I'll offer some
of my examples
and advice.
<?xml version="1.0" encoding="UTF-8"?>

Problem is that I don't totally understand how to use the
marshal/unmarshal methods described in:
If you could post an example of the xml to be
(un)marshalled, it would
help.
For the date/time, you may be going too far into the
examples. If the
DateTime is a single field in the XML you may want to look at
using
Serializer/Deserilzers.
http://jibx.sourceforge.net/tutorial/binding-custom.html#figure21
<http://jibx.sourceforge.net/tutorial/binding-custom.html#figure21>
In the marshal method (for JiBX), the Object parameter would
actually be
representing my DateTime object and I would be creating the
XML chunk
where this attribute lives in the Object/XML file. Is that
correct? I
ask because I see the startTagAttributes or endTag. Any
suggestions?
Also, for a global definition, what does the following
information stand
for:
m_uri = null;
m_index = 0;
m_name = null;
m_uri is the URI if the XML namespace. If your XML
file uses multiple
namespaces, this is the namespace URI for the element.
m_index is the index of the element name in the JiBX
internal data
structures.
m_name is the name of the element which encloses your
custom structure.
E.g. if your xml uses <datetime> xxxxx </datetime>, this would be
"datetime".
These are largely used as magic cookies. You should
never need to
change them, juss pass them back to the JiBX code.
I see it in the HashMapper example and I can see that it is
referenced
in the marshal/unmarshal methods.
This is my first custom mapper in JiBX and I am sure once I
write one,
the other ones will be totally easy.
You are correct, writing the mappers isn't difficult.
Cut and paste the
class constructors and the isExtension method from the
example. You will
need to write the following methods:
public void marshal(Object obj, IMarshallingContext ictx)
throws JiBXException
public Object unmarshal(Object obj, IUnmarshallingContext
ictx)
throws JiBXException
If you had an XML example I could show you some code.
