Field Joda Time in index

[smoers]

Hi all,

In my project, I use the package "Joda Time" to manipulate the dates.

I have problems to insert this object type in the index key.

If I not use a specific annotation, I receive this error : "Exception in thread "main" org.hibernate.search.SearchException: HSEARCH000135: Unable to guess FieldBridge for borndate in org.joda.time.DateTime"

I have try to use the annotation "@DateBridge(resolution=Resolution.DAY)", but I receive an error at the execution "Caused by: java.lang.ClassCastException: org.joda.time.DateTime cannot be cast to java.util.Date"

Can you help me ?

Hi Serge,

the transformation into indexable objects is handled by Hibernate Search, so this is the relevant documentation to index custom types: Hibernate Search custom bridges.

Essentially the framework automatically recognizes the standard types, but you can add support for any other type you might need. In particular Joda Time is widely requested, so we might add out-of-the-box support for it in a future release, but at the moment you'll need to declare a custom FieldBridge.
