Whoa! Glad I asked!
Seriously, thanks for the detail, it would have taken me a lot of time
to work all that out from scratch. The tip about package-info.java was
especially good, I've not seen one of those animals before. Eclipse
didn't like the name much either, as soon as I typed in the hyphen, but
it was happy again when I typed the last character.
For anyone else following this thread, who hasn't seen package-info.java
before, there's a bit about it about two-thirds of the way down this page:
http://java.sun.com/docs/books/jls/third_edition/html/packages.html
Your details below seem like they'd make a useful tutorial or howto on
the AppFuse site.

You're a smooth salesman ;-) Actually, I've just spent several hours
wrestling the "store time as a long solution" to the ground, and I've
not even started on date or datetime yet. I think it's time to break
out joda-time.
You wouldn't happen to have a snippet handy I could drop into my
.pom by
any chance would you? If it takes more than 30 seconds to find one,
don't worry, I'm sure I can work it out.
<dependency>
<groupId>joda-time</groupId>
<artifactId>joda-time</artifactId>
<version>${joda-time.version}</version>
</dependency>
<dependency>
<groupId>joda-time</groupId>
<artifactId>joda-time-hibernate</artifactId>
<version>${joda-time-hibernate.version}</version>
</dependency>
with joda-time.version = 1.4 and joda-time-hibernate.version = 1.0
To get it all working with Hibernate you will need a package-info.java
file in the same directory as your model classes. Sample included below:
@TypeDefs( { @TypeDef(name = "JodaDateTime", typeClass =
PersistentDateTime.class),
@TypeDef(name = "JodaLocalTime", typeClass =
PersistentLocalTimeAsTime.class),
@TypeDef(name = "JodaLocalDate", typeClass =
PersistentLocalDate.class)})
package com.mycompany.model;
import org.hibernate.annotations.TypeDef;
import org.hibernate.annotations.TypeDefs;
import org.joda.time.DateTime;
import org.joda.time.LocalDate;
import org.joda.time.LocalTime;
import org.joda.time.contrib.hibernate.PersistentDateTime ;
import org.joda.time.contrib.hibernate.PersistentLocalDate;
import org.joda.time.contrib.hibernate.PersistentLocalTimeAsTime;
You may need to add some additional typedefs as required. Once that
lot is in place simply annotate the getter of each Joda-time field
with the correct type, e.g.:
@Type(type = "JodaDateTime")
