Webmaster Forum / ColdFusion / Advanced Techniques / September 2007

Starting with the basics, can you type the URI to the WSDL file and get
the WSDL to display in a browser?  If so, you copied this URI into your
createOject code and it fails?

What OS?

Is there any security involved in the system generating the WSDL?

Thanks ian for prompt reply.

Yes I am getting the wsdl and thats what I pasted in my original request.
Exactly - The same URI in createObject or CFINVOKE does not work.

My CF MX 7.0 is on Windows 2k3.

I have been trying hard to make this work using CFINVOKE or CFHTTP invoking
operation name by passing it as a URI but no luck.

Any help will be highly appreciated..

Thanks.

Ian, Thanks but service is running on REMEDY system and is written in Java. The
new  wsdl looks like this..( Please check the complex type input and return
parameter). I cannot change the service permissions as its not in our control

I have modified my code a little to use a struct object and the code looks as
below..

---------------
<cfscript>    CreateInputMap1 = structNew();
     CreateInputMap1.Description = "test";
     CreateInputMap1.Requester_Login_Name = "xxxxxx";
     CreateInputMap1.Requester_Name = "yyyyyyy";

ws=CreateObject("webservice","http://oldtas184/arsys/WSDL/public/OLDTAS184/CHG_C
hange_WebService_OpCreate_DisplayOnly_v2?wsdl");
result= ws.opCreate(CreateInputMap1);
</cfscript>
<cfoutput>#result#</cfoutput>
-----------------
But I still receive the same error..

The REMEDY logs has this message -  "Required element expected in the input
XML document":

Note that the problem reported in the original posting was that the Apache Axis
WSDL2Java tool/library used by ColdFusion MX was throwing an error when trying
to generate the code that ColdFusion uses to consume the web service.

This generally indicates a badly formed WSDL (use a WSDL 1.1 validation tool)
or a bug in the code generator or both.
