I _think_ 801 may have been out around then, but if it was not, then it certainly makes sense why you would need this workaround. :) I just worry that people will see this entry and think they can't capture errors in cfexecute.

Unfortunately they were only documented in the 801 release notes (and missing from CF9!) but they provide support for capturing errors (either to a file or to a variable).

However getting access to the standard or error output is difficult to achieve with this approach. Hi Chris

I don’t believe we can access the PID from Java without extending out into some native win32 code, but for a non-blocking solution you may be able to do something like this:

<cfset cmd = "… your command …">
<cfset runtime = createObject("java", "java.lang.Runtime")>
<cfset process = runtime.getRuntime().exec(cmd)>

You could stores the "process" variable in your session or application scope and have access to it at a later time to terminate. However getting access to the standard or error output is difficult to achieve with this approach.

I'd like to run a short-lived server process and briefly interacts with Coldfusion, but I need the PID so I can terminate the process at the end of the request.
