Confusion about how the "Run Service" Webtools tool works

[Ruth Hoffman]

Hello List:

Back in the "old" days, you could use the Webtools "Run Service" tool to 
invoke a service synchronously from an HTML form. The process was, if 
I'm not mistaken: enter in the service name, any input parameters, hit 
submit and the Service was run. You didn't need to schedule it to have 
it run.

I'm trying to use the 9.04 & Trunk versions of the "Run Service" tool 
with testScv (as my service to run) and it appears as though I'm not 
able to run the service without actually scheduling it. Although the 
"Run Service" tool to tells me that my service was "Scheduled" 
successfully it never shows up any where on the Service Log.

Am I not using this tool correctly? Do I need to also "schedule" a 
service to have it run using the "Run Service" tool?
TIA
Ruth
