Hi,

does anyone know about a jsp taglib for hibernate.

Thanks

No - though I suppose this is an area that ripe for a contribution.

What kinds of functionality would you propose go into this Hibernate taglib?

Over here, we've written a straightforward taglib that operates much like a c:forEach given a hql query.

it's pretty full featured, being able to take a jdni context ( or generate from scratch ), let's you set start/max , and specify an iterate or a find ..


i'm not really sure that you'd need more than that for a hibernate tag ( though we've extended the core for our own purposes ),

but I'm sure my co wouldn't mind contributing back to the community.

Sounds great.

I wrote a few hibernate2.0 JSP tags a while back, I will update them for 2.1 and get them posted here by this weekend.

Here is the TLD. I got distracted before I ever got the criteria stuff working (it was very new at the time).

The session tag was a hack to get around a bug I was having in getting the Hibernate session servlet filter working.

Feedback is on this, more later...

Cool, sounds great - but from where can we get the taglib?

I'm looking to pass a Collection of object ids to a JSP, and have the JSP retrieve the relevant objects from Hibernate (and then present them), preferably via a tag library (taglib), so that I don't have loads of non-presentation code in the JSP. I don't want to pass a collection of objects to the JSP, as more potential then exists for the data to go stale.

Is there a Hibernate Tag library out there that would allow me to do this? Perhaps there is another, more commonly used approach to this?

No?? Then its back to the grindstone! :)
