1) you'll be able to write junit tests to see if the backend is behaving
2) decouple your application layers into something resembling MVC
3) If you decide one day to use something other than Hibernate, you will be able to rip out the persistence mechanism without touching your flow controllers
4) you can reuse your facade in other applications
etc.
All I am suggesting to you is that your flow code goes against a facade like this:
...
var myFacade = new ApplicationFacade();
var bug = myFacade.getBugsByStatus('UNCONFIRMED');
myFacade.close();
...The flow doesn't know or care that Hibernate/OJB/SOAP/JDO/JDBC/foo is behind the facade, which is precisely the point. Business logic shouldn't live in flow.

Hi all,
I am trying to add criteria inside a flowscript. Here is what i think should work:
1 var criteria = hs.createCriteria(Bug.class); 2 criteria.add(Expression.eq("status", "UNCONFIRMED")); 3 var bug = criteria.list();
this spits out : missing name after . operator on line 1
I have tried variations of switching to the the [""] syntax of calling methods, but while they fix the error, criteria is always undefined.
Anyone have insight into how i can call these methods in flow?
full function:
function search_bug() { // Create The Form var form = new Form("forms/bugSearchModel.xml");
// Set Some Form Specific Text Fields var model = form.getWidget(); model.buttonText = "Search"; model.title = "Search Bug Database";
form.showForm("internal/show-form/bugSearch");
// Create Hibernate Session
var factory = cocoon.getComponent(Packages.com.kismetsoftware.insecticide.PersistenceFactory.ROLE);
var hs = factory.createSession();
// Might as well quit now if the session is no good :(
if (hs == null){throw new Packages.org.apache.cocoon.ProcessingException("Hibernate session is null ");}
// This is problem Line: var criteria = hs.createCriteria(Bug.class); criteria.add(Expression.eq("status", "UNCONFIRMED")); var bug = criteria.list();
// Clean Up Our Mess :) hs.flush(); hs.close(); cocoon.releaseComponent(factory);
// Send The User Their Result
cocoon.sendPage("internal/generate-view/bug_summary", {title : "Bugs",bug : bug});
}
