AW: [postgis-users] PostGIS and Hibernate

[Thorsten Kraus]

Hi Andy,
 
I will try the tutorial and then I see if it works fine or not.
Just googled a little bit and perhaps I found a more interesting project which brings Hibernate and PostGIS together: MAJAS Hibernate Spatial ( http://www.cadrie.com/projects/majas-hibernate/ ).
Is anyone here who has experience with MAJAS?

Bye
Thorsten

Throsten,

I will try to answer your questions the best I can :

1) UserTypes are an offical Hibernate component thats lets you add mappings that Hibernate can use for non standard datatype, i.e. Geometry.  Seems as Norman wrote this specific UserType I don't think it will be supported by the Hibernate Team, but the should be able to provide general help on user types though. 

2) Seems as JBoss uses an embedded version of Tomcat, it should be possible.  I don't really know how to deploy stuff in Tomcat, but you should just put the user type in your .war or where the hibernate jars are. 

Cheers,

Andy

Hi Andy,
 
thanks for this useful information. I read the ejb3spatial.pdf and have some further questions on this topic :)
 
1. You mentioned that Norman Barker has created a user type for Hibernate. Is this user type an official component of the Hibernate framework or is it an addition where no support from the Hibernate team is guaranteed?
 
2. The tutorial in the pdf uses JBoss as application server. In my project I use Tomcat. So Tomcat is not a full application server, I think it is not possible to use Hibernate for PostGIS access in my project without changing the application server. Is this right?
 
Thanks,
Thorsten

Hi Thorsten,

A person called Norman Barker has created a user type for Hibernate, this can be accessed here http://svn.refractions.net/postgis/trunk/java/ejb3/  <http://svn.refractions.net/postgis/trunk/java/ejb3/> also read the ejb3spatial.pdf located here as it gives a example of how to use it.

Cheers,

Andy

Hi all, 

currently I am working for a project which uses PostGIS to store spatial objects in the backend of an web application (Tomcat is used as servlet container). Some time ago I searched the web for Hibernate support for PostGIS database and its geographical objects, but found nothing suitable. So I use Hibernate for non geographical attribute data and wrote some JDBC code for accessing the geographical objects in PostGIS. This hybrid structure of Hibernate and JDBC works fine, but it would even be nicer and more flexible if there was a possibility to handle all the database stuff with Hibernate. 

Can you tell me if there is Hibernate support for PostGIS meanwhile? If yes, a piece of code or a link to a tutorial would be pleasant.

Kind regards, 
Thorsten
