Debugging CFML

Trying to invoke a remote web service in ColdFusion and I want to see the exact request that's being generated and sent out.

I'm using some code like this:

<cfinvokeargument name="useremail" value=""/>
<cfinvokeargument name="userpass" value="samplepass"/>

How can I view the SOAP request that ColdFusion is generating from that? If it turns out ColdFusion's not formatting things in a way the web service wants, how else can I make a request with more control over the arrangement of the XML?

i remember seeing some sort of eclipse plugin that did exactly this, but i dont recall the name right now. You can always use an ethernet sniffer like wireshark (running on your cf server/development machine). If you use the "follow tcp stream" function you can see the request/response in all its ascii and hex glory.

Unfortunately, I don't have that level of access to the server. I'm really hoping to find something I can run within ColdFusion itself. Barring that, a public-access web service I can invoke that simply returns my request verbatim. That would be sufficient for debugging, and surely one exists somewhere... right?

Could you maybe just replace "" with the path to your own quick and dirty thingy that just echoes out what it's receiving?

If you're on windows, you might try Fiddler. It will let you view the request and response and also let you craft your own.

(1) Have you tried Stack Overflow for questions like this?

(2) I had a very similar problem recently, so I just hacked up this http proxy to rewrite the path of the request and print the request (and, optionally, response). Then I replaced with http://localhost:8080/path/to/webservice.asmx. This was sufficient to prove that the problem was on the other end :)

Charles is pretty great for this. It's similar to fiddler, but much better (interface-wise). It pretty-prints JSON and XML, and can parse AMF if you're into it. You can even rewrite and edit requests. The free version will run unrestricted for 1/2 hour before you need to restart it.

Thanks for the suggestions, I'll look into those. Does anybody know the structure of requests generated by <cfinvoke> as a general rule? It must follow some basic template.
