Re: CF Start a process - don't wait for it to finish
If only it were as simple as: !--- MyThread.cfc --- cfcomponent extends=java.lang.Thread cffunction name=run access=public returntype=any !--- do stuff that you don't need to wait for here, like launching an .exe --- /cffunction /cfcomponent !--- .cfm page --- cfscript mt = createObject(Component, MyThread); mt.start();// start is a method that would be inherited from Thread /cfscript But alas, it's not that simple.CFC's can't inherit from java classes.. So... in this situation it might make sense to create a Java wrapper that extends thread, and lets us assign a function to run as the thread.Maybe something with a simple API like this.. cffunction name=someFunction ... cfscript ThreadWrapper = createObject(Java, ThreadWrapper); ThreadWrapper.setMethodToRun(someFunction); ThreadWrapper.start(); /cfscript But I'm not sure have Java/CF play together with function references since I've never tried passing one from CF to Java before.If I get a chance, I'll play around with this when I get home from work tonight. -d - Original Message - From: Christian Cantrell To: CF-Talk Sent: Thursday, January 22, 2004 12:24 PM Subject: Re: CF Start a process - don't wait for it to finish On Wednesday, January 21, 2004, at 11:06PM, Taco Fleur wrote: What's the best way to start/call a process in CF and not wait for it to finish?

Re: CF Start a process - don't wait for it to finish
The onTap framework has a built-in method of doing this which is easily portable to other applications. Basically you generated content then use cfflush to push that content to the user, and perform the NSLookup (however it's performed) after the flush, so it processes after the user has already received their content. The onTap framework does this by providing a default flush and a queue of processes to be executed in the OnRequestEnd.cfm template. If you have concerns about users refreshing the page and causing unnecessary overhead on the system, you might want to include a page redirection (meta tag or _javascript_ - you can't use cflocation after a cfflush tag) in the content going to the browser. I use the _javascript_ location.replace() method which is analogous to cflocation in that it replaces the current entry in the browser's history, allowing the user to use their back button normally. The onTap framework has this function encapsulated into a couple of ColdFusion functions which provide some additional features. hth s. isaac dealey 214-823-9345 team macromedia volunteerhttp://www.macromedia.com/go/team chief architect, tapestry cmshttp://products.turnkey.to onTap is open sourcehttp://www.turnkey.to/ontap What's the best way to start/call a process in CF and not wait for it to finish?

RE: CF Start a process - don't wait for it to finish
That's a good question. IIRC on CF5 it was fairly easy to execute CFM pages with cfexecute if you knew how. Not sure if there's an easy way to do it with CFMX. If there is, it's probably different than it was on CF5. My tendancy would be to shy away from using either method, just for the sake of having a solution that's not dependant on a given version of the CF Server. But then I'm also fairly stringent about making my code as version agnostic as possible.

RE: CF Start a process - don't wait for it to finish
gotcha... in this case I'd recommend a similar solution. Use cfhttp to execute the other page and then use cflocation to redirect to someplace else. I _think_ you can execute cfhttp with a timeout of 0 and have the page continue processing immediately without waiting for the cfhttp content. I'm not certain of this tho -- I don't do a lot of work with cfhttp, so I'd have to go back to the docs and test it. For my own work, I have yet to run into any real issues with the way the framework handles it -- doesn't mean there aren't any, just that I haven't experienced them. Of course the framework also encapsulates the processes executing in the onrequestend to insulate them some from the remaining page.

RE: CF Start a process - don't wait for it to finish
I had been using cfhttp timeout=0 thinking it would timeout immediately. However it seems if you do this, the tag doesn't time out at all. Just something to watch out for. -Original Message- From: Taco Fleur [mailto:[EMAIL PROTECTED] Sent: Thursday, 22 January 2004 4:07 p.m. To: CF-Talk Subject: CF Start a process - don't wait for it to finish What's the best way to start/call a process in CF and not wait for it to finish?

Heh.

RE: CF Start a process - don't wait for it to finish
I was afraid of that.. After testing it, the answer is NOPE... It sits there and waits... I have one page that makes the call to another page, the timeout is set to 0 The other page contains a delay of 8 seconds and then writes a file More ideas needed...

Re: CF Start a process - don't wait for it to finish
Hi Taco, use cfschedule with action="" to create a task which runs once at now() + the scheduler interval to make sure it gets picked up.It will be stored as a schedule and triggered under a different thread, while your template goes about it's business.
