Web Service - this gets error . can anyone see why?
I want to consume a web service for converting currencies(at http://www.webservicex.net/CurrencyConvertor.asmx?wsdl )and I used the EXCELLENT implementation in DreamweaverMX to write the code.That drag and drop is an absolute gem for this! Anyway, the resulting page give an error and I cant see why because whats going in seems perfectly logical for what the web service is supposed to do. Heres the code that Dreamweaver wrote: cfinvoke webservice=http://www.webservicex.net/CurrencyConvertor.asmx?WSDL method=conversionRate returnvariable=conversionRateRet cfinvokeargument name=fromCurrency value=GBP/ cfinvokeargument name=toCurrency value=USD/ /cfinvoke Which (I thought) should take the input value GBP and work out a conversion to USD, and return a variable #conversionRateRet#which will be a number such as 1.02, being the conversion rate. However heres what I get: [quote] Could not perform web service invocation conversionRate because java.lang.IllegalArgumentException: argument type mismatch [/quote] And its highlighting the toCurrency line as the one with the error.Huh?If the fromCurrency line is correct, how come the next line isnt?Can anyone see whats wrong?Or is there something else I have to do on the page?

Mike, Did you try the enumerated type work around that Tom Jordahl posted? cfscript ws = CreateObject(webservice,http://www.webservicex.net/CurrencyConvertor.asmx?wsdl); enum = CreateObject(java, NET.webserviceX.www.Currency); argFrom = enum.fromString(GBP); argTo = enum.fromString(USD); result = ws.ConversionRate(argFrom, argTo); /cfscript Regards Stephen [EMAIL PROTECTED] [EMAIL PROTECTED] wrote: I want to consume a web service for converting currencies(at http://www.webservicex.net/CurrencyConvertor.asmx?wsdl )and I used the EXCELLENT implementation in DreamweaverMX to write the code.That drag and drop is an absolute gem for this!

RE: Web Service - this gets error . can anyone see why?
Hi Mike, I'm a bit of a novice at this stuff but I have found that just putting the webservice URL into my browser and then taking a look at the XML displayed is a useful way to solve these kind of issues if there is no better documentation. >From a quick look I would say that rather then two separate arguments, ConversionRate is expecting one structure that contains the 'from' and 'to' currencies.

Re: Web Service - this gets error . can anyone see why?
Mike,
The issue you have is that Currency, which is the data type for
fromCurrency and toCurrency is an enumerated data type.
There is a issue with CF/Axis and enumerated types.I believe that
Macromedia is aware of it, but have no idea what the status is or if
there is a decent work around.
I've been trying to sort out an issue with an enumerated data type on a
web service I'm trying to access and as yet I haven't had been able to
get a solution, other than to hard/hand code the soap packet and pass it
via cfhttp to the webservice. Not a usable solution unfortunately.
The other solution that someone suggested was to import the web service
and rewrite it to accept strings/numerics and post it out to the actual
web service (I think I got that right).Again not really a usable
solution.Why should you have to rewrite someone else's web service... :o{
If get a sensible solution, I would love to know!
Regards
Stephen

RE: Web Service - this gets error . can anyone see why?
Mike,
Yes, enumeration is the problem here.
I have fixed this, and I am working to try and get this fix available to
customers.
I apologize for this bug.No test for a situation means it doesn't work.
Now we have an enumeration test. :-)
In the mean time, try this workaround:
cfscript
ws = CreateObject(webservice,
http://www.webservicex.net/CurrencyConvertor.asmx?wsdl
http://www.webservicex.net/CurrencyConvertor.asmx?wsdl );
enum = CreateObject(java, NET.webserviceX.www.Currency);
argFrom = enum.fromString(GBP);
argTo = enum.fromString(USD);
result = ws.ConversionRate(argFrom, argTo);
/cfscript
The above workaround has one tricky problem however; you will need to copy
the class NET.webserviceX.www.Currency to a directory on the ColdFusion
classpath.I suggest C:\CFusionMX\wwwroot\WEB-INF\classes (adjust to your
installation directory).
Here is how to do that:
1. Run this page at least once and get the Class Not Found error.
2. Go to the CFusionMX/stubs directory and find the WS-
directory that has the NET sub directory.
3. Copy the NET directory to wwwroot/WEB-INF/class.
4. Delete all the .class files in the NET/webserviceX.www directory
EXCEPT Currency.class.
Sean Cornfield originally brought the issue up tome because of a thread on
CFGURU .Here is his web log posting on how to debug these issues:
