Hi Raul,
I do not know Tapestry, but I know HiveUtils (I wrote it;-)), the
contribution you describe below seems OK to me (at first sight).
However it depends exactly on what you want to achieve.
In particular is your POJO a singleton in your application, or do you need
to inject a new instance every time? From your initial Tapestry example, I
believe it is a singleton, so when using HiveUtils, you should probably put
the "cache" attribute to true to make sure HiveUtils will not create more
than one instance:
<contribution configuration-id="hiveutils.ObjectBuilderObjects">
<object name="globalMenu" cached="true"
class="com.estudiowebs.CMS.DAO.GlobalMenu">
<inject
object="service:com.estudiowebs.CMS.services.EntityService" />
<inject-arg />
</object>
</contribution>
Please note however that according to the above config (independently of the
cache attribute), you need to use hiveutils.ObjectBuilder service to get the
instance of your object because, you have declared your POJO to require a
runtime argument in the constructor ("<inject-arg/>") which means the
constructor for it should look like:
public GlobalMenu(com.estudiowebs.CMS.services.EntityService
service,
MyArgType myarg) {...
NB: MyArgType can be any type.
Then to get the instance of your POJO you need to do:
ObjectBuilder builder =...
GlobalMenu globaleMenu = builder.create("globalMenu", myArg);
where myArg is of type MyArgType.
Is this what you want to do?
Do you really need the extra runtime argument?
If not then it would make it easier to inject globalMenu into other objects,
services, or configurations by using:
"object:globalMenu"
I hope it gives you a better view of what you can do and how you can do it,
now if you need further precisions or if you want to give more details about
what you want to do, you are welcome.
One last point: HiveUtils is part of the HiveMind Utilities project on
SourceForge (formarly known as "hivetranse"), which is independent of
HiveMind and Tapestry (by independent I talk about the involved persons and
the communication channels). So it might be better to proceed with this
discussion on the HiveMind Utilities forums, except if this is a common
Tapestry problem.
Cheers
Jean-Francois

Subject: Re: Injecting registry services to POJOS
I was trying to do that using hiveutils, sorry, but still very new to
hivemind and IOC:
<contribution configuration-id="hiveutils.ObjectBuilderObjects">
<objectname="globalMenu"cached="false"class="com.estudiowebs.CMS.DAO.GlobalM
enu">
<inject
object="service:com.estudiowebs.CMS.services.EntityService" />
<inject-arg />
</object>
</contribution>
I just need and example on how to inject one of my services in one of my
POJO so that I can access my hibernate session from my pojos.
Thanks.
Raul.
