So, I'm getting some compile errors on netbeans 6.5 generated web service code for a java ME client to a c# (vs2005) web service. I've trimmed my example significantly, and it still shows the problem, and not being able to return a collection of things is pretty much a deal-breaker.

c# web service (SimpleWebService.asmx)

<%@ WebService Language="C#" Class="SimpleWebService" %>

using System;
using System.Web;
using System.Web.Services;
using System.Web.Services.Protocols;

[WebService(Namespace = "http://sphereinabox.com/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
public class SimpleWebService  : System.Web.Services.WebService {

    [WebMethod]
    public CustomType[] GetSomething() {
        return new CustomType[] {new CustomType("hi"), new CustomType("bye")};
    }
    public class CustomType {
    	public string Name;
    	public CustomType(string _name) {
    		Name = _name;
    	}
    	public CustomType() {
    	}
    }
}

Generated (netbeans) code that fails to compile, this was created going through the "Add -> New JavaME to Web Services Client" wizard. (SimpleWebService_Stub.java)

    public ArrayOfCustomType GetSomething() throws java.rmi.RemoteException {
        Object inputObject[] = new Object[] {
        };

        Operation op = Operation.newInstance( _qname_operation_GetSomething, _type_GetSomething, _type_GetSomethingResponse );
        _prepOperation( op );
        op.setProperty( Operation.SOAPACTION_URI_PROPERTY, "http://sphereinabox.com/GetSomething" );
        Object resultObj;
        try {
            resultObj = op.invoke( inputObject );
        } catch( JAXRPCException e ) {
            Throwable cause = e.getLinkedCause();
            if( cause instanceof java.rmi.RemoteException ) {
                throw (java.rmi.RemoteException) cause;
            }
            throw e;
        }

//////// Error on next line, symbol ArrayOfCustomType_fromObject not defined
        return ArrayOfCustomType_fromObject((Object[])((Object[]) resultObj)[0]);
    }

it turns out with this contrived example (the "CustomType" in my production problem has more than one field) I also get errors from this fun code in the same generated (SimpleWebService_Stub.java) generated code. The errors are that string isn't defined (it's String in java, and besides I think this should be talking about CustomType anyway).

private static string string_fromObject( Object obj[] ) {
    if(obj == null) return null;
    string result = new string();
    return result;
}
