Starting Workflow on a schedule

I have been trying this for a while, and gotten to the point I will describe below.The following is a script which I intend to have run on a schedule (more on that below). For debugging purposes I have also set it up as a rule which runs when I want it to run, but the end result is to have it run o

After trying this for a while, I can re-phrase my problem.

When I give the queryTemplate property a value that exists, such as:

    <property name="queryTemplate">
    <value>PATH:"/app:company_home"</value>
    </property>‍‍‍

the scheduled action runs, or at least tries to run. I get the following as an error:


13:58:00,638 ERROR [freemarker.runtime] Template processing error: "No nodes selected"

No nodes selected
The problematic instruction:
———-
==> ${selectSingleNode('workspace://SpacesStore', 'lucene', 'PATH:"/app:company_home/app:dictionary/app:scripts/cm:findExpiringContracts.js"' )} [on line 1, column 1 in string://fixed]
———-

If I look at the following link (from the person who pointed me in this direction in the first place):

http://4lch3mi5t.wordpress.com/2012/07/26/scheduled-custom-action-alfresco/

the advice given is that the problematic instruction isn't finding the node from my javascript file – which definitely exists, and is a javascript file (so sayeth the Node Browser) – because I'm using Solr rather than Lucene. My production server is using Solr, though, and I'd rather not rebuild the thing just to get this to work. As it is, I have the following as a workaround:

1. Windows Task Scheduler executes a batch file, which contains the line "start http://blahblahblah/ScheduledAction.aspx"
2. This runs a web application, which runs the following web script: modifyProperty (with a nodeRef passed in the querystring)
3. The web script alters the description of the file associated with that nodeRef by passing in the current date
4. Altering this file triggers a rule which executes a script which does what I want it to do

(At this point the crossbow fires, severing the rope which is holding up the anvil, causing the anvil to plummet onto the seesaw, which will launch a net a the Roadrunner…)

So, am I barking up the right tree with respect to the necessity to use a Solr query rather than a Lucene query? If so, what would be the right Solr query?
