ok... I merged the two WSDL documents into one WSDL document and the code
worked. It appears as if there might be some kind of bug with the Axis
code that consumes WSDL's with imports. The bug was introduced post Axis
1.0.

RE: Bean Mapping Issues
James:
I made a couple of small changes to your WSDL, notably compressed it into
one file and corrected the address to match the service on my machine ("
http://localhost:8080/axis/services/quote";). Then I ran it through
WSDL2Java, creating a server-side implementation, stubs, and the data
classes.
Used this impl:
public NasdaqQuotes_types.NasdaqQuote getPrice(java.lang.String symbol)
throws java.rmi.RemoteException {
NasdaqQuote nq = new NasdaqQuote();
nq.setSymbol(symbol);
nq.setLastSalePrice(45.5D);
return nq;
}
Then I ran this:
public class NQTest {
public static void main(String[] args) throws Exception {
QName svcQName = new QName("http://NasdaqQuotes-Interface";,
"NasdaqQuotesService");
QName portQName = new QName("http://NasdaqQuotes-Interface";, "quote");
QName typeQName = new QName("urn:NasdaqQuotes-types", "NasdaqQuote");
Service service = new Service("NasdaqQuotes.wsdl", svcQName);
Call call = (Call)service.createCall(portQName, "getPrice");
call.registerTypeMapping(NasdaqQuote.class, typeQName,
BeanSerializerFactory.class,
BeanDeserializerFactory.class);
call.setReturnType(typeQName);
NasdaqQuote nq = (NasdaqQuote)call.invoke(new Object [] { "foo" });
System.out.println(nq.toString());
}
}
And when I had the debugger stop at the println at the end, the
NasdaqQuote was filled in correctly. So I don't know what's going on for
you - it could be that something weird is happening with the import, since
I did squash it into one WSDL, but that seems unlikely. I'm using the
latest codebase, btw.
Did you figure anything more out after you were fortified by your snack?
:)
