[flexcoders] Re: Choice of backend systems - which provides best functionality
WS-Security is the standard spec for securing web service calls. Most web service stacks have some level of support for it. Among the things it offers are username/token style security and encryption of some/all of the SOAP envelope. There is an overview and a few good links here: http://www-128.ibm.com/developerworks/library/specification/ws- secure/ Also, see the Adobe AS3 UsernameToken support in the corelibs project here: http://weblogs.macromedia.com/as_libraries/docs/corelib/ Hope that helps, Derek --- In flexcoders@yahoogroups.com, Darren Houle [EMAIL PROTECTED] wrote: Franck, Makes sense to me.

[flexcoders] Re: WSDLError:Element not resolvable
I use a similar system in my app for disabling the controls until the service is loaded. In the "load" handler, I add handlers for faults and results for the various operations (I don't use operation tags, but instead manually register everything in AS). Here is the general idea...
!-- Web service connector -- mx:WebService id="MyWebService" wsdl="http://services.cadtel.com/jbpm-webapp/wsdl/jbpm.wsdl" useProxy="false" showBusyCursor="true" concurrency="multiple" load="MyJbpmWebService.init(); Dashboard.enabled=true;" fault="MyJbpmWebService.defaultFault(event);" /
The "init()" method looks like this... public function init():void { service.addEventListener("fault", defaultFault); service.GetProcessDefinitions.addEventListener("result", getProcessDefinitionsResponse); service.GetProcessInstances.addEventListener("result", getProcessInstancesResponse); service.NewProcessInstance.addEventListener("result", newProcessInstanceResponse); service.SignalProcessInstance.addEventListener("result", signalProcessInstanceResponse); }
... and the method that is failing looks like this ...
/** * Create XML and send apos;getProcessInstancesapos; message to web service. */ public function getProcessInstances(definitionId:int):void { var xml:XML = new XML( "jbpm:GetProcessInstances xmlns:jbpm=\"http://org.jbpm/service\" " + " xmlns:typ=\"http://org.jbpm/types\"" + " definitionId=\"" + definitionId + "\"/"); service.GetProcessInstances.request = xml; service.GetProcessInstances.resultFormat = "e4x"; try { service.GetProcessInstances.send(); } catch (e:WSDLError) { // TODO: Nasty hack to get around first call failing... service.GetProcessInstances.send(); } } /** * Handles response from getProcessInstances() web service call. */ protected function getProcessInstancesResponse(event:ResultEvent):void { if (!checkForFault(XMLList(event.result))) { controller.receivedGetProcessInstancesResponse( XML(event.result[0].types::ProcessInstances)); } }
Note the try...catch block that resubmits the message. Ths fixes the problem, but seems like a huge hack. I have no idea why all of the other operations work fine, but the first call to that particular one always fails. It would be nice to have the source for the WebService class so that I could trace into it, but that doesn't seem to be included in the SDK.
Thanks,Derek Adams

This can take some time and is an asynchronous process. This means that the webservice loads the WSDL in the background. If it is not finished loading/parsing the wsdl and you try to invoke an operation it will return errors.Try to wait a few seconds and invoke it then, if the error still remains, then this is the reason. How to solve it? I did it like this:secWsImpl = new WebService(); secWsImpl.addEventListener(LoadEvent.LOAD, handleWsLoaded); secWsImpl.addEventListener("fault", handleWsError); secWsImpl.loadWSDL("/FlexTestWebServices/wsdl/SecurityWebServiceRpcEnc8080.wsdl");In the method 'handleWsLoaded' you can then invoke an operation if you'd like, or enable a button or something like that.Cheers, Frnack -- From: flexcoders@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Derek Adams Sent: Sunday, August 06, 2006 11:56 PM To: flexcoders@yahoogroups.com Subject: [flexcoders] Re: WSDLError:Element not resolvableDid you have any luck figuring this one out?

[flexcoders] Re: Spring Enable Flex
You can emulate a lot of what Spring provides without adding anything to Flex. For instance, you can use dependency injection by exposing a public variable on a class and using data binding to inject the object/value from MXML. I guess what I am getting at is that MXML pretty much becomes the Spring config file. --- In flexcoders@yahoogroups.com, Allen Riddle [EMAIL PROTECTED] wrote: I'm not having any issues, it's just nice because it's one less configuration format to learn.

[flexcoders] Re: How to parse web services response doc containing namespace
I have been successful in doing that by declaring the namespace as a
local variable in ActionScript, then using it in the e4x query. For
instance:
private var aps:Namespace = new Namespace
(http://cadtel.com/APWebService;);
model.currentOrderPaths =
results.aps::Order.aps::RelatedPaths.aps::Paths.aps::NetworkPath;
Hope that helps,

If you do not set resultFormat as e4x, but instead do:
var xmlResult:XML = newXML(result.toString())
for me, that created an xml object without the namespace stuff.
Let me know if it works.

Subject: [flexcoders] How to parse web services response doc
containing
namespace
I am a complete newbie to Flex, ActionScript et al, so please
forgive me if my questions appear simplistic.
I've implemented, and got working, the sample app which invokes
a
web service and displays the Top 5 popular posts from a blog
service.
I now want to modify this app so it calls my own homegrown web
service. I have been able to get the invocation working, and I
get a
valid response, which I confirmed by displaying the lastResult
object in a textbox.
My problem now is I want to parse through the result document,
which
contains a namespace, and populate items on the form - I have
not
yet been successful in my attempts.
Here is the source code to my MXML application, followed by the

[flexcoders] Re: FileReference and mimetypes
I had the same problem with mime types. My solution was to use the file suffix to figure out the content type. I was using a servlet on the backend, so I just called getServletContext().getMimeType(filename). In your case, you may want to pass the mime type in a separate variable on the URL and use that to override the content type in the backend processing logic. Something like this:
var vars:URLVariables = new URLVariables();vars.sessionId = manager.getSessionId();vars.contentType = overridingContentType;uploadRequest = new URLRequest();uploadRequest.url = ""http://my-upload-processor/upload">http://my-upload-processor/upload";uploadRequest.data = "">file.upload(uploadRequest);
Hope that helps,
Derek
