[groovy-user] GroovyWS - Complex Response
nico2280
Hi,
I'm trying to use groovyWS, but I don't know how to catch the response type
wich is more complex than I used to see ... usually my response is just a
string. With my code below, the result is just the first string ... how can
I make for having all the response's elements ?
Thanks by advance
<element name="checkVatResponse">
<complexType>
<sequence>
<element name="countryCode" type="xsd:string"/>
<element name="vatNumber" type="xsd:string"/>
<element name="requestDate" type="xsd:date"/>
<element name="valid" type="xsd:boolean"/>
<element name="name" type="xsd:string"/>
<element name="address" type="xsd:string"/>
</sequence>
</complexType>
</element>
here is the wsdl file :
http://ec.europa.eu/taxation_customs/vies/api/checkVatPort?wsdl
And here is my code :
//
import groovyx.net.ws.WSClient
def proxy = new
WSClient("http://ec.europa.eu/taxation_customs/vies/api/checkVatPort?wsdl",
this.class.classLoader)
proxy.initialize()
def result = proxy.checkVat("BE","65655");
println result
//

this issue is related to a wrapped/unwrapped call. The way of invoking
the method should be cofigurable (memo for me: write Guillaume) ;)).
Sometimes you have to pass each member. :/ For these cases the error is
always like yours below.
Please try this:
def checkVat0 =
proxy.create("eu.europa.ec.taxud.vies.services.checkvat.types.CheckVat")
checkVat0.countryCode = "LU" //<string>
checkVat0.vatNumber = "21405308" //<string>
def result = proxy.checkVat(checkVat0.countryCode, checkVat0.vatNumber)
This results in (converted into a map) :
0={result=LU}, 1={result=21405308}, 2={SIXTY=null,
LEAP_YEAR_DEFAULT=null, FIELD_NAME=null, SECOND=null,
second=-2147483648, DECIMAL_ONE=null, orig_minute=null,
MILLISECOND=null, TWENTY_FOUR=null, YEAR=null, FOUR=null, TIMEZONE=null,
DECIMAL_ZERO=null, TWELVE=null, orig_fracSeconds=null, daysInMonth=null,
minute=-2147483648, DECIMAL_SIXTY=null, timezone=-2147483648, DAY=null,
orig_eon=null, BILLION=null, HOUR=null, serialVersionUID=null,
year=2009, MONTH=null, eon=null, orig_day=null, orig_month=null,
hour=-2147483648, MAX_FIELD_VALUE=null, orig_second=null,
orig_hour=null, orig_timezone=null, fractionalSecond=null,
PURE_GREGORIAN_CHANGE=null, HUNDRED=null, orig_year=null, month=9,
MINUTE=null, FOUR_HUNDRED=null, MIN_FIELD_VALUE=null, day=17},
3={result=true}, 4={result=---}, 5={result=---}}
Regards,
Dennis.

Just another question,
how do you convert the result in a Map ?
When I use your code Denis, my result.class is a java.lang.String.
Thanks again.

I'm using the reflection mechanism of groovy and a recursive method. ;)
(and I just found a bug because of your service - thx.)
> When I use your code Denis, my result.class is a java.lang.String.
The wsdl says:
<element name="checkVatResponse">
<complexType>
<sequence>
<element name="countryCode" type="xsd:string"/>
<element name="vatNumber" type="xsd:string"/>
<element name="requestDate" type="xsd:date"/>
<element name="valid" type="xsd:boolean"/>
<element name="name" type="xsd:string"/>
<element name="address" type="xsd:string"/>
</sequence>
</complexType>
</element>
The webservice call should return an object of this type. Debugging the
result shows that there is an object-array containing each member stated
above. :/
The current implementation returns only the first element of an array.
This should be _countryCode_ which leads to your string result.
If you create your own ws-client by extending WSClient.java, you could
use this workaround. This workaround was discussed earlier in this
mailing list (it doesn't work out always).
/* (non-Javadoc)
* @see
groovyx.net.ws.AbstractCXFWSClient#parseResponse(java.lang.Object[])
*/
@Override
protected Object parseResponse(Object[] response)
{
if (response.length == 1)
{
return response[0];
}
return new ArrayList<Object>(Arrays.asList(response));
}
Regards.

Okay ...
I'm checking it.
Thanks for your time.

Is this still the case? I'm getting the same error, but with a much bigger
object :(

Denis, I have the same problem. The result is not a map, but a String.
Is it a bug? I have to recompile some classes on server side?
This problem may be very common, it is not strange for you?
Thank you

Hi Francesco,
I don't get it. Could you post some details?

This is my code:
import groovyx.net.ws.WSClient
def proxy = new
WSClient("http://ec.europa.eu/taxation_customs/vies/api/checkVatPort?wsdl",
this.class.classLoader)
proxy.initialize()
def checkVat =
proxy.create("eu.europa.ec.taxud.vies.services.checkvat.types.CheckVat")
checkVat.countryCode = "LU"
checkVat.vatNumber = "21405308"
def resp = proxy.checkVat(checkVat);
print resp
The result (resp) is a String ("LU"), not a map, like the wdsl declare....

Hi Francesco,
I debugged the given service and cxf returns:
[LU, 21405308, 2010-04-15+02:00, true, null, null]
As I stated below GroovyWS contains a bug returning just the first
element of an array (return response[0];). The solution provided at the
end of the mail should be a workaround for you as long as there ain't no
bugfix.
Nevertheless the return value should be an object rather than an array,
I guess. Perhaps someone on the cxf list can answer this?!
Regards,
Dennis.
tog
I am working on this, I should provide a fix today, tomorrow at the latest.
Best Regards
Guillaume
