    <p>I was handed a legacy Spring Hibernate DAO project that was Spring 3.2.0 and Hibernate 3.5. I converted it upstream to Spring 3.2.3.RELEASE, and Hibernate 4.2.3.Final.</p> <p>The problem is that they used Joda-Time for peristing date/times to the database, but from what I have read here, joda-time-hibernate 1.3 does not work for Hibernate 4, but only for 3. So, I looked at the recommended libraries and spent a lot of time converting Joda.DateTime to jadira.PersistentDateTime, but what I found was that Jadira ... IMHO doesn't work that great for my needs. Yes, I can pull objects from the database, and these are Jadira PersistentDateTime fields, this works great.</p> <p>However, we have lots and lots and lots of date calculations used with joda-time, one for adding days, emoving days, difference between days, before, after calculations, and the list goes on.</p> <p>So ... I am wondering ... can I convert a joda.DateTime to and from jadira.PersistentDateTime???? I also find the documentation for Jadira non-existent, I find almost no good documentation out there. If someone can point me out to this documentation that would be great.</p> <p>On the other hand, since I am using Hibernate 4 now, I see no problem with just using a standard java.util.Date for my persistent objects.</p> <p>Should I stick to jadira, is it worth it? Or should I use the standard reliable java.util.Date with the GregorianCalendar? I am leaning toward the latter since it should be more stable and reliable that some exotic third-party package.</p> <p>Thanks! Tom</p>

    1. COThankyou for advising about the two blank pages (Howto and Bugs)... actually both can be removed, as bugs are tracked through jadira.atlassian.net, and howto is covered by the User Guide page. The Jadira docs have the same coverage as Joda Time contrib but do not list all the types. You can select your types by looking at the Javadoc - they are all prefixed with 'Persistent', I don't list them because there are about 40 and growing.

    2. COI assume you meant you converted joda.PERSISTENTDateTime to jadira.PersistentDateTime? As to your maths functions, can you give an example of what they are, without that it is difficult to suggest how to resolve.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
