Flash Remoting Call Timing Out

[Jamie Jackson]

I'm trying to get going with some Flash Remoting from Flex, but I'm having a tough time of it. My requests from Flex seem to time out, but if I call the same CFC/method, called via http://mysite/cfc/myCfc.cfc?method=myMethod syntax, it works right away.

Any ideas as to how to fix or troubleshoot this? Please let me know what more info you might need from me in order to help.

Thanks,
Jamie

Here's my CFC's method: (/cfc/AddressService.cfc?method=getStates)
====================================================
        <cffunction name="getStates" access="remote" output="false" returntype="query">
                <cfset var local = structNew() />
<cfscript>
local.states = querySim('
stateID,countryID,state,state_abbr
1|1|Alabama|AL
2|1|Alaska|AK
....snip...
58|1|Wyoming|WY
');
return local.states;
</cfscript>
        </cffunction>
       
        <cffunction name="getCountries" access="public" output="false" returntype="any">
                <cfreturn countries />
        </cffunction>

Here's the service setup in MXML
==========================================
  <mx:RemoteObject id="addressService"
                source="cfc/AddressService"  
                destination="ColdFusion"
                fault="faultHandler(event)"
                requestTimeout="10">
                <mx:method name="getStates" result="resultHandler(event)"/>
        </mx:RemoteObject>

In Flex, I'm having my app dump its error:
==========================================
Request timed out


And here's what I get from the CF console:
===========================================
[Flex] null
java.lang.IllegalStateException

your source is wrong.  Flex uses a . syntax same as Coldfusion when calling
cfcs.
your source should read cfc.AddressService

Thanks for the suggestion, but I don't think it's the ticket.

I get the same behavior with "/" and with "." ...see the following.

Thanks for the idea though, please keep them coming. :)

cfc.AddressService yields:
Request timed out

cfc/AddressService yields:
Request timed out

cfc.blah.AddressService yields:
Unable to invoke CFC - Could not find the ColdFusion Component or Interface cfc.blah.AddressService.

cfc/blah/AddressService yields:
Unable to invoke CFC - Could not find the ColdFusion Component or Interface cfc/blah/AddressService.

Have you tried removing your request timeout?  It is set to 10.  I would
unset it if you are having timeout problems, perhaps that will reveal
another issue, or solve the problem.

I added the timeout because I got bored of the waits. The operation should take very little time.

When I ran the flex debugger without a timeout, I noticed that it went into some kind of re-queueing routine (into native Flex AS classes) seemingly ad infinitum.

I just now set a timeout of 60 seconds, and same timeout. Now I'll do it again without a timeout, but AFAIK, it's not going to end up telling me anything, unfortunately. I'll report back if it does, though.

what happens when you don't run it through the flex debugger?  Have you
tried setting up a new project and just calling the CFC from it?  Perhaps
there is a setting off in the current flex project?  Where are the CFCs
stored?

Thanks for the suggestion. I did just learn about use-mappings this afternoon.

The CFC I'm calling is indeed under the web root, though.

I'll try the non-debugger Flash player and see if it makes a difference, to rule out debugging related stuff.

Yeah, there could be, and it could easily be something like that, but I'm too new to FB to be able to easily spot something that's amiss.

Under the web root, in a dir called cfc, but let me know if you need more detail than that.

Ahh, okay. I've got multi-server, so my paths don't match up quite like that, but no, it's in my virtual host web root, not under the CF8 wwwroot (which is /opt/jrun4/servers/childwelfare_old/cfusion.ear/cfusion.war, I think).

so then you will have to do what Paul suggested and edit the file to go to
the correct web root :)

So is there no way to put the CFCs in any other place, and have them still work? It seems bizarre to require that flash remoting apps need some files to go over here (in the virtual host root), and some to go over there (in the "CF" web root). But is that the way it has to work?

Consider this. Here's the way I wanted it to work.

Say my virtual host doc root is:
/var/www/apps/myapp/wwwroot/

My internal CFCs are here:
/var/www/apps/model/

And my remote apps (that serve as remote proxies for my internal CFCs) are here:
/var/www/apps/model/cfc/

My Flex app is here:
/var/www/apps/myapp/wwwroot/flex/

Is that not possible? If not, why? This stuff is still pretty new and foreign to me.

Thanks again,
Jamie

Bah, I messed up those paths, so just to correct them to avoid confusion:

Say my virtual host doc root is:
/var/www/apps/myapp/wwwroot/
 
My internal CFCs are here:
/var/www/apps/myapp/model/
 
And my remote CFCs (that serve as remote proxies for my internal CFCs) are here:
/var/www/apps/myapp/wwwroot/cfc/

My Flex app is here:
/var/www/apps/myapp/wwwroot/flex/

yes there is a way, you add the dir to your CF mapping and then in your flex
install edit the config to look for CFCs inside the CF mapped directories.
 Your situation will work fine, with external and internal CFCs just that
the external CFC directory has to be known to CF so that it can share it
with Flex when needed.
to do so, go to your ColdFusion 8 (i presume 8) install directory, go to the
wwwroot dir, open the web-inf dir, open the flex dir, open the
remoting-config.xml  in there you will find the following:

            <access>
                <!-- Use the ColdFusion mappings to find CFCs, by default
only CFC files under your webroot can be found. -->
                <use-mappings>true</use-mappings> **** Change this to TRUE
                <!-- allow "public and remote" or just "remote" methods to
be invoked -->
                <method-access-level>remote</method-access-level>
            </access>


then you can use the local references from your mapped dir to get to your
CFCs, and this would be a one-time thing.  I personally don't have a
multi-server model, so I can't say if there is anything else required for
that.

Jamie,

cfcs don't need to be directly exposed under the webroot, I also use
your approach by putting them under some other folder and I also use
multiserver version. The only thing you'll need, like others mentioned,
is to set use mappings = true so the MessageBroker /flex2gateway
endpoint use any mappings used by that application.

Using Application.cfc you can use <cfset this.mappings['/model'] =
'/var/www/apps/myapp/model/'/> and then your remote project just have to
use invoke them using
createObject('component','model.pathToYourDesiredCFC');

Thanks João and Rob.

Unfortunately, I think I already have the things in place that you mentioned. Let me recap everything I've got. Please let me know if you see anything wrong, or if you need to see anything else.

The following always times out from Flex, but works every time, right away, from
http://myapp.localhost/cfc/AddressService.cfc?method=getStates

Here are all the details I can think of:

My virtual host doc root is:
/var/www/apps/myapp/wwwroot/

My internal CFCs are here:
/var/www/apps/myapp/model/

And my remote CFCs (that serve as remote proxies for my internal CFCs) are here:
/var/www/apps/myapp/wwwroot/cfc/

My Flex app is here:
/var/www/apps/myapp/wwwroot/flex/

"/myapp" CF Mapping points here:
/var/www/apps/myapp

Here's the relevant bit from my remoting-config.xml file:
<access>

    <!-- Use the ColdFusion mappings to find CFCs, by default only CFC files under your webroot can be found. -->

    <use-mappings>true</use-mappings>

    <!-- allow "public and remote" or just "remote" methods to be invoked -->

    <method-access-level>remote</method-access-level>

</access>

My Flex RemoteObject is defined like this:
<!-- I've tried it with both myapp.wwwroot.cfc.AddressService and cfc.AddressService -->
 <mx:RemoteObject id="addressService"
        source="myapp.wwwroot.cfc.AddressService"  
        destination="ColdFusion"
        fault="faultHandler(event)"
        >
        <!-- This service's returned query has the following columns:
                stateID,countryID,state,state_abbr
                notice that it has a specific result handler -->
        <mx:method name="getStates" result="resultHandler(event)"/>
</mx:RemoteObject>

And the method it calls looks like this:
<cffunction name="getStates" access="remote" output="false" returntype="query">
<cfset var local = structNew() />
<cfscript>
local.states = querySim('
stateID,countryID,state,state_abbr
.... snip ...
58|1|Wyoming|WY
');
return local.states;
</cfscript>
</cffunction>

Wait, I think I might be on way towards fixing this. I think the symptoms were misleading me as to the source of the problem. I'll post back with the resolution if I fix it.

If you are loading as
http://myapp.localhost/cfc/AddressService.cfc?method=getStates you can't
use
<mx:RemoteObject id="addressService"
source="myapp.wwwroot.cfc.AddressService" ... but you should use instead
<mx:RemoteObject id="addressService" source="cfc.AddressService" ...

The main app's Application.cfm was doing strange things in the context of an AMF call, and causing misleading symptoms.

Here's what finally fixed it: I put a new Application.cfm in my (external) cfc directory, and used <cfapplication name="myMainApp'sAppName" />. This way, I'm using the main app's app variables (which are all I need from it), but I'm disinheriting all the garbage that's in the main app's Application.cfm.

Thanks very much to both of you, as your help jumpstarted my change of tack!
