ColdFusion Flash Remoting Configuration in Flex 2 Beta 2

I think I have tracked the problem down to some missing lines in the web.xml file involving the flex2gateway. Not sure why after uninstalling everything, neither flex, cf, or the cf connector would add these lines. More info at: http://www.drisgill.com/index.cfm/2006/3/22/Flex-2-Beta-2--flex2gateway-Problem

Still having tons of problems on my home computer, but for reference. I installed everything on my work computer and remoting worked flawlessly out of the box (without editing any xml). So i'm thinking something is crufty on my home computer even after uninstalling cf and fb. Personally I think it had to do with the old Flex Enterprise Data stuff that I installed in prev beta (and have since uninstalled). I think something is hanging on to that rather than the remoting.

I too am having trouble with Flash Remoting in Flex 2 Beta 2. I have the Coldfusion/Flex Connection installed on Coldfusion MX 7 Stardard, and am using the Flex 2 Eclipse Plugin for development. When trying to run the Phones example I am only getting a busy cursor once the app loads. I have updated the flex-enterprise-services.xml file to reflect my configuration (IIS port 80). I have also added the --services argument to the compiler option. I have compared the FES file posted against mine with the only difference being the entpoint-uri.

Rich, is that where you are passing list.selectedItem (an object) to ProductDetails (which expects a Phone object)? If so, change {list.selectedItem} to {Phone(list.selectedItem)}, that casting should do it. --- Ben

I am not having any trouble getting the Coldfusion/Flex Connection to work. I have a made a simple hello world that is able to pass data back and forth from a Flex Client to a .CFC. I just can't get any of your samples to work with Beta 2. I keep getting compile errors: Implicit coercion of a value with static type 'Object' to a possibly unrelated type 'Phone' Main.mxml Phones line 37.

Correction, the endpoint looks like this: <endpoint uri="{context.root}/flex2gateway/" class="flex.messaging.endpoints.AMFEndpoint" />

I kept getting an error like this when trying the new adapter: Error: faultCode:Client.Error.MessageSend faultString:'Send failed' faultDetail:'Channel.Connect.Failed error NetConnection.Call.Failed: HTTP: Status 500' at mx.rpc::AbstractInvoker/http://www.adobe.com/2006/flex/mx/internal::faultHandler() at flash.events::EventDispatcher/dispatchEvent() at mx.messaging::MessageAgent/fault() at mx.messaging::Producer/fault() at mx.messaging::ChannelSet/::faultPendingSends() at mx.messaging::ChannelSet/handleChannelFault() at flash.events::EventDispatcher/dispatchEvent() at mx.messaging::Channel/mx.messaging:Channel::connectFailed() at mx.messaging.channels::NetConnectionChannel/mx.messaging.channels:NetConnectionChannel::connectFailed() at mx.messaging.channels::AMFChannel/mx.messaging.channels:AMFChannel::statusHandler() Took me a while to figure out what was wrong, but when I checked the Coldfusion logs (JRUN4logscfusion-event.log) i noticed the required JVM was not installed. The one that comes with JRUN4 apparently does not meet the required version. I installed JAVA SDK 1.4.2.11, changed the JVM in the JRUN administrator, restarted server and everything started working ;-) Also note that I changed the <endpoint> into: http://{context.root}/flex2gateway/ That way I am able to connect from any PC on the network. Hope this helps, Muzak

After finding more time I was able to finally get a gateway connection. My endpoint uri had to contain the actual host name like this: <endpoint uri="[HOST NAME]/flex2gateway/" class="flex.messaging.endpoints.AMFEndpoint" />. I had also Restarted the server after modifying the flex-enterprise-services.xml file. However, using ServiceCapture as a debug tool for the Remoting calls, the endpoint was NOT relecting my current changes. I'm not sure if it was time, or ONLY making enough modifications to the file and then clicking the Run icon in FB that finally the endpoint was corrected. Now that I have jumped this hurdle, I am encountering anothe issue: Could not find the ColdFusion Component CFIDE.samples.Phones.CF.Catalog. I have placed this sample in the default location, and the test.cfm file included runs fine. Any ideas?

Ok..I have tried just about every combination that is listed here..so I will give my setup and see what everyone has to say..here is my error> Error: faultCode:Client.Error.MessageSend faultString:'Send failed' faultDetail:'Channel.Connect.Failed error NetConnection.Call.Failed: HTTP: Status 500' at mx.rpc::AbstractInvoker/http://www.adobe.com/2006/flex/mx/internal::faultHandler() at flash.events::EventDispatcher/dispatchEvent() at mx.messaging::MessageAgent/fault() at mx.messaging::Producer/fault() at mx.messaging::ChannelSet/::faultPendingSends() at mx.messaging::ChannelSet/handleChannelFault() at flash.events::EventDispatcher/dispatchEvent() at mx.messaging::Channel/mx.messaging:Channel::connectFailed() at mx.messaging.channels::NetConnectionChannel/mx.messaging.channels:NetConnectionChannel::connectFailed() at mx.messaging.channels::AMFChannel/mx.messaging.channels:AMFChannel::statusHandler() Here is my services entry --services=y:CFusionMX7wwwrootWEB-INFflexflex-enterprise-services.xml I have a mapped drive from my laptop to the webserver and I am using Flexbuilder on my laptop not the webserver.

Here is a section from my coldfusion-event.log but I am still having problems with the endpoint port... 04/18 15:05:27 user failed to load: flex.messaging.MessageBrokerServlet 04/18 15:05:27 error Invalid endpoint port '' specified for channel definition 'my-cfamf'.

Does anyone have any ideas about my previous post? Thanks

I have the same problem as Ben but with the Flex2 Beta3. The flex-enterprise-services.xml file looks quite different to the one above. There is no mention of the coldFusion service in there. Can anyone post a good copy from Flex2 Beta3 for me please? Kevin

can anyone explain me please how to use NetConnectionDebugger with flex2?

Ben, I just installed Flex 2, and have data connectivity between Flex and WebServices (CFC's). If I try to convert to using Flash Remoting I get the errors listed here. I have tried every configuration that I have found on the web but so far it has not worked. Any insight you may have would be a great help to me. I am new to Flex, but so far I am really enjoying how easy it is to program.

Enzo, Are you using a locla CF server running 7.0.2? You should not need to worry about the issues raised in this thread in the final product. So long as Flex Builder can find the CF services-config.xml it should just work. This thread applied to the beta when stuff was not as simple. --- Ben

Pablo, can you make calls to the Flash Remoting 2 path without an error? Also, if you start CF in console mode are you seeing any useful log info? --- ben

I'm having similar problems, with Flex Builder 2 and a local copy of CF 7.0.2. I've configured my services-config.xml to point to the local web server and host, but still no luck. Any ideas?

Thanks for the quick response, Ben. I figured out the problem on my own: the ColdFusion setup was actually fine -- the problem was that my browser (Firefox 2) had cached the SWF from a previous build, where the flex/services-config.xml was pointing to the wrong place. I cleared out the cache, and everything started working. Thanks!

Hi! I am using Flex 3 beta remoting with CF MX 7.0.2 but keep getting "Send Failed" error. Here's snippet from C:CFusionMX7wwwrootWEB-INFflexservices-config.xml: The file originally contained: uri="http://{server.name}:{server.port}{context.root}/flex2gateway/" I changed it to: 1. uri="http://localhost:8500{context.root}/flex2gateway/ 2. uri="http://localhost{context.root}/flex2gateway/ Still no luck. Please help! Thanks.

I am currently experiencing the same problem as Sameer. I developed a Flex application that retrieves data from a ColdFusion CFC by use of a remote object. I'm using Flex Builder 3 along with Coldfusion MX7. I am new to Flex and I am having a hard time trying to troubleshoot my problem. When I deployed the application on my local machine, everything worked perfect. The problem started when trying to deploy it to our company server. I keep getting a "send failed" error. I then tried to verify that my Flex gateway was working properly by entering http://www.my-website.com/flex2gateway/ in my browser. Sure enough I received a 404 error instead of a blank screen. I have saturated forums trying to figure out what I need to do in order to deploy this application. Everything I have tried seems to have a dead end. Halp!

Wow I can't believe that post so long ago is still helping folks. 2006! Glad it helped.

Thanks to rd's post on 3/22, I've launched my first Flex application! If anyone runs into a Flex gateway 404 error, I suggest looking at the link below. It solved my gateway problem and I was able to launch my first Flex application. http://www.drisgill.com/index.cfm/2006/3/22/Flex-2-Beta-2--flex2gateway-Problem Thanks RD! Ben, I would like to thank you for supplying the public with a useful and detailed blog. I have solved many of problems here!
