Hibernate JRCollectionDataSource

2005-05-03 01:05

Hi Jasper Experts,


I have a question.

When i retrieve an object from hibernate it looks like:


relationBean which has a Set of AdresBean.


How can I do this. Do i have to use a subreport?

I looked had hibernate.org where they have posted a HibernateQueryDataSource class but this one only work for a relationBean which has a AdresBean but not a Set of AdresBean.


Anybody suggestions?

If you have a collection of RelationBean and each

RelationBean has a set of AdresBean, then you should

have in your master report a field of type Object that

has the same name as the Set property of the

RelationBean object.

Then, to your subreport, you will pass this as data source:


new JRBeanCollectionDataSource((Set)mySetField)


This way, for each RelationBean in the master report

data source, the subreport will iterate through the

set of AdresBean objects.


I hope this helps.
