Description

Check if JAXB works correctly with JodaTime.

The following came with the JodaTime mailing list:

I was converting some code to use a DateTime instead of a Date and a property has an @XmlElement annotation. Having apparently stumbled on to a web service, some Googling eventually found me http://blog.bdoughan.com/2011/05/jaxb-and-joda-time-dates-and-times.html

Is that kind of thing presently the recommended approach? Is there some semi-standard library we should be using or should I just roll my own marshaller?

I've never used JAXB myself, nor have I heard of anyone doing an integration library, so that blog post is probably the state of the art.

The blog post covers the basics. If you don't control the Web Service and so can't add your annotations then there's a technique where you use "xjb" to modify the generated source that you create using wsimport.

One issue you will typically find is that there isn't really a "standard" when it comes to webservices - every webservice seems to be ever so slightly different to each other. Date Times with or without time and time zone is often a point of different despite the the "standards".
