[jdom-interest] Fw: How to date type conversion between xml and Java

[Jack Bush]

Thank you to both Jason & Tatu,

Below is an attempt which I haven't yet being able to verify even though it has 
been deployed in EJB 3.0 (Glassfish 2.1) container:

    org.jdom.Element collectionDateTime = 
((org.jdom.Element)area_element).getChild("collection_date_and_time");
    SimpleDateFormat collection_date_formatter = new 
SimpleDateFormat("dd/MM/yyyy");
    Date collection_date_parsed = 
collection_date_formatter.parse(collectionDateTime.getTextNormalize());
    futureStock.setCollectionDate(collection_date_parsed);

    SimpleDateFormat collection_time_formatter = new SimpleDateFormat("hh:mm:ss 
a");
    Date collection_time_parsed = 
collection_time_formatter.parse(collectionDateTime.getTextNormalize());
    futureStock.setCollectionTime(collection_time_parsed);

I am awaiting to test out the JPA persistent once the 
"java.io.UTFDataFormatException" issue is resolved.

Thanks again,
Jack

Also, might want to consider Joda library, which is an improvement over JDK 
defaults, both in functionality and (I think) with respect to efficiency. Can 
usually just construct DateTime out of typical (ISO-8601) date Strings.
