SOAP and WebService

[exobyte]

I'm trying to send SOAP requests with WebService.

WebService.loadWSDL seems to load the configuration stuff. I know I can use getOperation, then Send to send things, but the callbacks from the AsyncToken never seem to get called.

Am I doing things right? I don't want to do this with the UI XML; I want to do it in ActionScript.

I'm not sure Send is what I really want to do, and I'm not sure what the parameters are for a remote call.

Say I have

<SomeOperation xmlns="http://foo.com/file">
  <Parameter1>foo</Parameter1>
  <Parameter2>bar</Parameter2>
</SomeOperation >

the xmlns and SomeOperation part should have been parsed with loadWSDL (I think). I'm not sure how to send the parameters. I tried making XML objects with Parameter1 as the root, but I didn't get a response.

Pointers, examples, and anything else would be appreciated.

Thank you!

Update:

I can call functions and get callbacks, but the calls aren't working, yet.

To call a function, do "<webservice object>.<method name>(<parameters>);"

Callbacks are done with "<webservice object>.addEventListenter(<Event ID>, callback);"

My problem is that I keep getting faults, and the message is null, so I'm not sure how to debug it.

I grabbed Hotfix 3 for Flex 2. I know that I'm not having any cross-domain issues (same domain, and I fixed it when it was on a different domain).

Now I get this:

HTTP request error
(mx.messaging.messages::ErrorMessage)#0
  body = (Object)#1
  clientId = "DirectHTTPChannel0"
  correlationId = "C5EF8C74-6413-12CF-7737-7E8FE675B002"
  destination = ""
  extendedData = (null)
  faultCode = "Server.Error.Request"
  faultDetail = "Error: [IOErrorEvent type="ioError" bubbles=false cancelable=false eventPhase=2 text="Error #2032: Stream Error. URL: https://foo.com/soap"]. URL: https://foo.com/soap"
  faultString = "HTTP request error"
  headers = (Object)#2
  messageId = "55F24685-6626-C774-F58E-7E8FE6E39495"
  rootCause = (flash.events::IOErrorEvent)#3
    bubbles = false
    cancelable = false
    currentTarget = (flash.net::URLLoader)#4
      bytesLoaded = 0
      bytesTotal = 0
      data = (null)
      dataFormat = "text"
    eventPhase = 2
    target = (flash.net::URLLoader)#4
    text = "Error #2032: Stream Error. URL: https://foo.com/soap"
    type = "ioError"
  timestamp = 0
  timeToLive = 0

I'm calling the method like this:

<webservice object>.<method>(<string parameter1>, <string parameter 2>);

Both strings are the XML strings the server expects.

Ideas?

http://bugs.adobe.com/jira/browse/SDK-11250 hmm...

If I use "_<tag>foo</tag>" I do indeed get a malformed XML error, but replacing < and > with &lt; and &gt; gives me the same error. I'm not sure what was mean by "escape," either--XML or unix \, though \ has meaning to the parser, and this is at runtime.

Passing XML arguments instead of XML strings gives me the same error.

Using the mxml version gives me the same error, so that's not it.

Using Paros (very cool tool for this stuff, might I add) I noticed a "tns:" preceding the normal XML stuff. This is what was actually sent to the server.

<tns:Command xmlns:tns="http://foo.com/path/file">
      <tns:Parameter>bar</tns:Parameter>
</tns:Command>

I don't have access to the server, but from the docs, it isn't expecting any of the "tns:" stuff.

Ideas?

I found my bug. It looks like there was a server error. The message just didn't make it back to Flex.

I read about a feature request/bug about this.
