Hi Jakob,
The root is just the root from which to evaluate the path. This is just like
the root option to xdmp:spawn. The path is then relative to the root. So if
your root is /foo/ and your path is hello.xqy, then it will resolve to
/foo/hello.xqy.
It looks like things are configured correctly in your system, but it is easy to
accidentally overlook something. Is it possible you added that module to a
different database?
Here is what I tried successfully:
1) create a text file that is an xquery main module. I created mine in the
database names "Modules":
xdmp:document-insert("/test/test.xqy", text {"xdmp:log('hello')"})
2) configure a scheduled task. Mine has these setting:
task path /test/test.xqy
task root /
task type daily
task period 1
task start time 2:12 PM
task database Modules
task modules Modules
task user admin
task host server-name.marklogic.com
At 2:12 I saw the following in my ErrorLog.txt:
2009-08-10 14:12:00.532 Info: TaskServer: hello
3) Test my module in cq as follows:
xquery version "1.0-ml";
xdmp:spawn("/test/test.xqy", (),
<options xmlns="xdmp:eval">
<modules>{xdmp:database("Modules")}</modules>
<root>/</root>
</options>)
I see the following in my log:
2009-08-10 14:18:41.499 Info: TaskServer: hello
Maybe if you can try something like that, then compare the process with what
you are doing, it will help find the solution?

yes, it does.

doing this for my xquery file returns, as hoped for, "text".

yes, this has become an RFE, it seems. :)
so, does this mean, on paper everything works as it should? what's
the next step to test? could you explain the idea behind the task
root property, I haven't grasped it so far.
