Why Mage::log not write any thing in my log file and also how will i check my cron is running or not. pLease help me out !!!!

回答1:

You don't declare your models in your config.xml but observer is a model. You should add

<models>
        <jr_createadmincontroller>
            <class>JR_CreateAdminController_Model</class>
        </jr_createadmincontroller>
    </models>

In the global node. And change this

<run><model>createadmincontroller/observer::setStatus</model></run>

By this:

<run><model>jr_createadmincontroller/observer::setStatus</model></run>
