JAXB Custom Binding for Joda-Time

I’m extensively using Joda-Time for handling time in my Java development, client or server side. Joda-Time is the codebase of the coming RI implementation of JSR-310 that will hopefully ship in Java 7.

I often need to work with dates in web services implementations, here is the JAXB custom binding lines I use to un/marshall JodaTime types to standard xs:date and xs:dateTime XML Schema types.

Note : I’m using the RI implementation of JAXB spec bundled in Metro.

Glassfish, Hibernate and WebServices – WSGEN Classpath

Following my quick and dirty how-to about using hibernate in glassfish I came across a small pitfall when dealing with metro webservices.

The glassfish’s wsgen classpath on Glassfish is not by domain, ie. the wsgen tool is not run in the domain class-loader.

When trying to deploy a webservice that returns an entity with a hibernate annotation, I got this following error :

Server logs showed the following trace :

/home/paul/Programs/glassfish-v2-b58g/domains/domain1/applications/j2ee-apps/ear-0.1-SNAPSHOT/lib/entities-0.1-SNAPSHOT.jar(app/model/entities/User.class):
        warning: Cannot find annotation method 'value()' in type 'org.hibernate.annotations.Fetch':

Adding the hibernate-annotations.jar file in the glassfish main lib/ directory added the necessary classes to the wsgen classpath.
