Hi Raul,
>From what I saw in another of your emails, I guess what you have to do if
you want to use HiveUtils is a config like this:
<contribution configuration-id="hiveutils.ObjectBuilderObjects">
<object name="globalMenu" cached="true"
class="com.estudiowebs.CMS.DAO.GlobalMenu">
<inject name="EntityService"
object="service:com.estudiowebs.CMS.services.EntityService" />
</object>
</contribution>
This will call the default constructor of GlobalMenu and then inject the
EntityService through the setter method.
Now the problem still remains on the Tapestry side: how to inject the pojo
globalMenu to the tapestry.state.ApplicationObjects configuration?
Since I do not have Tapestry on hand I cannot check what is possible to do
in the contributions for this configuration, but I suppose there must be a
way (an attribute) to inject your POJO by using "object:globalMenu".
Now for your question about a HiveMind utilities newsgroup, unfortunately
not (or not yet). The only way currently is to use the online forums (I hate
that but I discovered that my provider's email server was not recognized by
SourceForge so that any mail sent to the SF newsgroup would fail because of
my own email address! Actually I plan to change this addres, but that is not
done yet). Hope to create a mailing list soon.
Cheers
Jean-Francois

Subject: Re: Injecting registry services to POJOS
Hi Jean-Francois, first of all thanks for your help,
My pojo is basicaly the menu of my webapp, since everybody will have the
same I thought that the best thing would be to make it an application
scope object and fetch the records at startup. since i have already
declared a Hibernate Session service I wanted to inject that service
into this object so that I could use it to query the objects.
I have also many webservices in the same webapp that are not tapestry
related and I'd like to use these services both in the tapestry and
servlets.
I think this is or would be a common problem for Tapestry 4 users.
Many have already asked how to access the Tapestry hivemind registry
from other objects that are not of type Component or Page. My problem is
that I don't even know if this is posible since someone mentioned in
this newsgroup that the Tapestry hivemind registry wasn't available
directly and also annotations like @InjectObject only work within pages
or components.
Anyway, I'll try your solution,
Is there a newsgroup for Hivemind utilities?
Thanks,
Raul.
