TargetNameSpace for a ComplexType

Hello everyone,

I'm new and I'm not sure if someone has asked this before, if that's the
case, sorry, guys :)

Anyway, I'm trying to invoke a service that returns a complex type (let's
say, "blah"), and as you must know it's necessary to map the type:

QName qn = new QName( targetNS, className);
service.mapType( qn, Class.forName(classLocation));

Currently, I'm presuming the user of my class knows the targetNS for that
complexType, but unfortonately, that's not possible. Does anyone knows how
to get the targetnamespace for a complex type? I know I can get the
targetnamespace using this command:
(presuming I've read the wsdl already)

System.out.println(def.getNamespaces());
In my sample, the result would be:
{impl=http://cit05:8080/axis/services/ServerFileTrans,
intf=http://cit05:8080/axis/services/ServerFileTrans,
wsdlsoap=http://schemas.xmlsoap.org/wsdl/soap/,
apachesoap=http://xml.apache.org/xml-soap,
soapenc=http://schemas.xmlsoap.org/soap/encoding/,
xsd=http://www.w3.org/2001/XMLSchema,
wsdl=http://schemas.xmlsoap.org/wsdl/,
tns1=urn:ServerFileTrans, =http://schemas.xmlsoap.org/wsdl/}

The targetnamespace I need is named "tns1" in this case. But that's not a
standart, I mean, it could be different. (I've seen "targetnamespaces"
with different names in other samples)

Is there any other way to get the TargetNameSpace for a ComplexType,
reading it from the WSDL? Could anyone please help me??

Thanks and sorry about my english :(
