Re: Hibernate and Bean binding

[Corin Moss]

Hi,
At the risk of talking to myself, and being called mad I thought I'd 
report back on the following:

1. One way of doing what I described below is by using the fb:javascript 
binding.

I chucked the following:
<fb:javascript id="create_kw_rel" path="/">
 <fb:load-form>
 </fb:load-form>
 <fb:save-form>
   var programme_id = this.lookupWidget("programme_id").getValue()
   var keyword_id = this.lookupWidget("new_keyword_id").getValue()
  
   //create Hibernate session
   var factory = cocoon.getComponent(Packages.hib.PersistenceFactory.ROLE);
   var hs = factory.createSession();
   if (hs == null) {
     throw new 
Packages.org.apache.cocoon.ProcessingException("Hibernate session is 
null ");
   }

   var create_rel_bean = new Packages.nz.co.eunomia.KeywordRelationship(
       new Packages.nz.co.eunomia.KeywordRelationshipPK(
           new Packages.nz.co.eunomia.Keywords(new 
java.math.BigDecimal(keyword_id))
           , new Packages.nz.co.eunomia.Programme(new 
java.math.BigDecimal(programme_id)
           )
   ),
   //obviously this shouldn't be hard coded - but for the purposes of 
testing it's fine.
   new java.math.BigDecimal("4")
   );

   hs.save(create_rel_bean);
     hs.flush();
     //release
     hs.close();
     cocoon.releaseComponent(factory);
 </fb:save-form>
</fb:javascript>
into my binding document.
Now, this doesn't strike me as the cleanest thing in the world - does 
anyone have any comments or thoughts?

Thanks,
Corin

Hi All,
I sent an email a few days ago asking for some advice on how to map a 
hibernate one-to-many relationship to cforms using the binding 
framework.  My request may have been a bit vauge, as I haven't had any 
response yet.   The original email can be seen here:
http://marc.theaimsgroup.com/?l=xml-cocoon-users&m=111214181513587&w=2

Since then, I've tested my understanding of the hibernate side of the 
question by doing the following in flowscript:

   var create_rel_bean = new Packages.nz.co.eunomia.KeywordRelationship(
       new Packages.nz.co.eunomia.KeywordRelationshipPK(
           new Packages.nz.co.eunomia.Keywords(new 
java.math.BigDecimal("4"))
           , new Packages.nz.co.eunomia.Programme(new 
java.math.BigDecimal("1")
           )
   ),
   new java.math.BigDecimal("4")
   );

This creates a new keyword_relationship entry perfectly.  Of course, 
the references to Keywords and Programme (with hard coded ids) is 
where the binding should be happening - as part of the context of (for 
example) a "Programme" bean. Given this, and the other material 
included above,  is there a simple way to do this with binding, or 
should I rely on using flow-script and getting a handle on form values 
to do this?

Thanks,
Corin
