Hello Kevin:
Thanks Kevin, so, now I put on my hivemodule file this
<contribution configuration-id="tapestry.state.ApplicationObjects">
<state-object name="Logger" scope="application">
<create-instance class="org.apache.commons.logging.Log"/>
</state-object>
</contribution>
I has a doubt about the create-instance part because commons-logging has
its own LogFactory, and other doubt is about how I can set the
properties file maybe (follow the example) <create-instance
class="org.apache.commons.logging.Log,
log4j.configuration=/WEB-INF/classes/log4jproperties.xml"/>?
My .java parent page
@InjectState("Logger")
protected abstract Log getLogger();
But now, my app complaint and show this message on the child page (even
if I inject directly on MainForm.java)
Error at context:/WEB-INF/MainForm.page, line 5, column 50: Method
'protected abstract org.apache.commons.logging.Log
com.pct.SIG.MainPadre.getLogger()' (declared in class
com.pct.SIG.MainPadre) has no implementation in class
com.pct.SIG.MainForm (or enhanced subclass $MainForm_22).
location: context:/WEB-INF/MainForm.page, line 5, column 50

What I'm doing wrong?, because I don't have enough experience managing
hivemind
Thanks

Hi Jorge,
It seems to me that an ASO would be your best bet. Give it an
application scope and you'll only create a single instance for the
life of your app. If you need to do some funky configuration when
starting, then you can create a StateObjectFactory wrapper. A service
would really only be necessary if you were looking to write some sort
of facade, and even then, I'm not sure it'd gain you a whole lot. If
you're looking to do it a bit more dynamically, you could look into
using aspectj to hook in as appropriate.
Hope that helps.
