Returning Arrays from .net web service to Java ME web service results in compile error of stub?
- by sphereinabox
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;
}
