jsp:setProperty tag
In a jsp page I use: jsp:useBean id="personaFisicaNP" class="it.unical.anagrafiche.np.PersonaFisicaNP" /jsp:setProperty name="personaFisicaNP" property="*" / This page is called from another form jsp page with a certain number of form fields... Well, some fields of my bean are String, some other are Integer. I get that the setProperty tag works well with String type fileds, but Integer ones return nulls... I got jsp specification from Sun and I saw that Integer, String, Byte and so on should be returned well from a form containing this kind of objects. I tryed my code on JRun 3.1 and it goes with no problem. Is this an Orion problem or am I missing something? Thanks in advance, Nicola

Re: Returning Collections from ejbFindXXX()
When you return something in a Collection ejbFindByXXX method, what you
return is the KEY of your table (in your case I think the key is a
String...). What you get in the home interface is a collection of remote
references of your ejb-object (for example Customer object in a CustomerBean
ejb...).

Subject: Returning Collections from ejbFindXXX()
Hi,
Has anyone tried to return Collections from a BMP ejbFindAll() type of
operation?
I return an ArrayList of String objects, the client receives this list ok
but gets a cast exception on trying to extract the String from the list.
eg.
public Collection ejbFindAll() throws java.rmi.RemoteException,
javax.ejb.FinderException
{
ArrayList v = new ArrayList();
v.add("First");
v.add("Second");
return v;
}
and the client code:
Collection coll = home.findAll();
System.out.println(coll.size() + coll.toString()); // this shows
correct count and contents: "2[First, Second]"
Iterator iterator = coll.iterator();
while(iterator.hasNext())
{
String s = (String)iterator.next();// class cast exception
System.out.println("Desc=" + s);
}
On closer inspection with a debugger it turns out the objects in the list
are of class __Proxy5, some sort of orion proxy object.
This appears to be a bug but I'd like to be sure in case its me. Has
anyone
done this successfully?
I'm using orion 1.4.5, I cannot seem to upgrade with autoupdate due to
(probably) firewall restrictions.
TIA
Permjeet
Re: usebean tag
Dear Alessandro,
the problem is in the page where I use the tag. I miss that value just
there and I save the dipartimentoQuery in the session. The mai problem is
with the jsp:setProperty tag. It saves string values, but losts Integers!
You're Italian, aren't you? I'm from Cosenza...
Thanks...

This is the code:
jsp:useBean id="dipartimentoQuery"

jsp:setProperty name="dipartimentoQuery" property="*" /
In my jsp page this code would take the values from a previous form and
take them in my bean, but I lost the Integer value idUniversita (it was
in
a select tag). So I had to take it by a
request.getParameer("idUniversita")... Is this an Orion bug, is this a
Nicola's bug? Too strange!
Thanks in advance...
Nicola,
When you use the jsp:useBean tag with that syntax, you are inserting
that
bean in the page scope. Once the page is completed, that scope will be
cleaned up and your bean will be lost, so, if in a previous page you have
set the idUniversita member, it will be lost. Try inserting that bean in
the session scope, for example, so it will be accessible to the next page
and you will not use that value.
Best Regards,
Kazuma
