RE: [flexcoders] flex2gateway error
It could very well be that your request response time is exceeding the default time out for Remote Objects, but I'm not sure about app not working *at all* after that. This can create the intermittent behavior you're seeing, depending on load or query response time from the app's database. In AIR this is a real problem because on windows, the request times out at 30 seconds no matter what you do. But you say you're running a Flex app so, you *should* be able to set the requestTimeout on your RemoteObject to a higher value and see a mitigation of the behavior. HTH.

Running on Windows on Apache. Everything seems to work fine but then randomly (as far as I can tell) I'll start getting those flex2gateway errors: [RPC Fault faultString=Send failed faultCode=Client.Error.MessageSend faultDetail=Channel.Connect.Failed error NetConnection.Call.Failed: HTTP: Failed: url: 'http://localhost/flex2gateway/'] Everything I've read on this list and elsewhere refers to this error appearing when the gateway isn't working...but it seems to be for me. When I manually call the URL above (http://localhost/flex2gateway/) I get the whitepage that is expected (I double-checked the headers and they do give me 200 response). Once this error appears I have a VERY hard time getting rid of it and getting my application to run again. I've tried restarting Apache, ColdFusion, even rebooting, I've tried rebuilding the project, I've tried manually setting the gateway in my remote object tags. Nothing seems to work, but invariably it *will* go away for a time, everything will run correctly...and then boom, it shows up again and I'm stuck again. But I have yet to figure out the pattern for when it occurs. Any ideas?? I'm really frustrated trying to figure this out and what it causing it. -- Mary Jo Sminkey Author, CFWebstore ColdFusion Ecommerce

Re: [flexcoders] flex2gateway error
I think Charles Proxy may be useful for you to diagnose these problems. Also take a look at your server log. What server technology are you using? PHP? Apache? Generally when we see these types of fault they appear as a 500 response from the server. Have you stepped thorough your server side code. Also we have seen intermittant errors in Internet explorer that were due to a badly configured https remote connection.

Re: [flexcoders] flex2gateway error
I think Charles Proxy may be useful for you to diagnose these problems. Okay, not familiar with it, but I'll look into it. Also take a look at your server log. Which one? Nothing appears to get written to any of the CF server logs when I hit the application, I don't see any errors in Apache or any reference at all to the flex2gateway. Are there other logs I should be checking? What server technology are you using? PHP? Apache? ColdFusion 9.01 running on Windows with Apache. Generally when we see these types of fault they appear as a 500 response from the server. Nope, that's what is so weird in my case, if I hit the localhost/flex2gateway manually it returns a normal 200 response. But for some reason, within the Flash component, it can't seem to find it.

Re: [flexcoders] flex2gateway error
Okay in a default apache install there is a request log. Take a look at that when you see the error on screen and make sure theres no lines ending in 500 (most lines should be 100, 200) Charles proxy is used for debugging what data is sent over the wire via amf.

There doesn't seem to be a channel config, and I'm not seeing anything
in the remoting config that would play into this. Perhaps you mean the
services config file? That is where I see all the channel definitions,
which all look similar to this:
endpoint
uri=http://{server.name}:{server.port}{context.root}/flex2gateway/;
class=coldfusion.flash.messaging.CFAMFEndPoint/
I did one point try manually setting that endpoint to
localhost/flex2gateway and restarted the CF server to see if that
effected it, but still did get the error.

Re: [flexcoders] flex2gateway error
Well, I'm still dead in the water, tried uninstalling and reinstalling Flash Builder to no avail. Tried a couple other things as well that didn't effect it either. The link to the forums that I posted below is a bit hard to follow with the broken English, but they seem to describe their application working when FB is open, and not working when it is closed. Mine is not running regardless of whether it is open or not...and in the debug error message it doesn't show that port address even though the http listener is showing it so I'm not convinced the Network Monitor has anything to do with it. I *do* have a feeling I've hit some kind of FB bug so I may see if we have an Adobe support contract to make use of. If not, I may have to figure out how to compile via the SDK just to verify that the Flash Builder product is the problem. -Original Message- From: flexcoders@yahoogroups.com mailto:flexcoders%40yahoogroups.com [mailto:flexcoders@yahoogroups.com mailto:flexcoders%40yahoogroups.com] On Behalf Of Mary Jo Sminkey Sent: Thursday, August 19, 2010 3:30 PM To: flexcoders@yahoogroups.com mailto:flexcoders%40yahoogroups.com Subject: Re: [flexcoders] flex2gateway error On 8/19/2010 2:43 PM, Wesley Acheson wrote: Charles proxy is used for debugging what data is sent over the wire via amf.

Re: [flexcoders] flex2gateway error
Got it fixed! Found the bug report on the Flex Jira site that included instructions for fixing it. Was indeed the Network Monitor causing the problem. Here's the link in case anyone else runs across this: https://bugs.adobe.com/jira/browse/FB-27235 Thanks for the help in finding this. --- Mary Jo

Subject: [flexcoders] flex2gateway
error, Coldfusion and Flex intergration
I have been trying to integrate a flex application into a
Coldfusion application. I first developed a standalone flex application in Flex
Builder 2.0, which worked fine. I then imbedded the SWF file into a page on my
Coldfusion application and moved the CFCs into the application. The
application runs on another instance of Coldfusion. I have configured the
additional compiler arguments in Flex builder 2.0 to point to the new server
instance:
-services C:\JRun4\servers\{server name}\cfusion.ear\cfusion.war\WEB-INF\flex\services-config.xml
-locale en_US
also I have changed the flex server root:
C:\JRun4\servers\{server name}\cfusion.ear\cfusion.war\
All CFC paths have been updated to reflect the new locations.
When the app runs the SWF has a button that calls a function of a
remote object, which returns a string to be displayed (very simple), but all I
get back is an error:
fault:Channel.Call.failed
faultString: error
faultDetail:NetConnection.Call.Failed: HTTP:
Failed
On the server side I can see the client communicating with the
server and then an error is thrown:
[Flex] HttpFlexSession has not been registered as a listener in
web.xml for this application so no e
vents will be dispatched to FlexSessionAttributeListeners or FlexSessionBindingListeners.
To correct
this, register flex.messaging.HttpFlexSession as a
listener in web.xml.
18/08 11:03:08 error No configured channel has an endpoint path
'/flex2gateway/index.cfm'.
flex.messaging.MessageException: No configured channel
has an endpoint path '/flex2gateway/index.cfm
'.
Can anyone point me in the right direction, maybe some
documentation?
Thanks, Justin
