Hello !!

I wrote a web service in Netbeans 6.7, and two clients for it, one web client, and a mobile client. The web client works fine, but the mobile clients does not work when i use complex types in the methods. When i generate the mobile client on Netbeans 6.5, it works.

I found that the error is in the Stub class generated by the IDE:
The "complex type" :

Code:

public class IGCAddress
{
public String fullname;
public String id;
public String nbhoodL;
public String nbhoodR;
public int height;
}

The service method:

Code:

@WebMethod(operationName = "getTestAddress")
public IGCAddress[] getTestAddress() { ... return array }

The 6.7 method, in IGCService_Stub class:

Code:

public igcAddress[] getAddress(String streetname, int height) throws java.rmi.RemoteException {
Object inputObject[] = new Object[] {
streetname,
new Integer(height)
};

Operation op = Operation.newInstance( _qname_operation_getAddress, _type_getAddress, _type_getAddressResponse );
_prepOperation( op );
op.setProperty( Operation.SOAPACTION_URI_PROPERTY, "" );
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;
}

return igcAddress_ArrayfromObject((Object[]) resultObj);
}

The 6.5 method, in IGCService_Stub class:

Code:

Note that differ only in the last line (return line). If you change the last line in the 6.7 method
by the last line in the 6.5 method, then it works. If not, this is the error:

java.lang.ClassCastException
at igcservice.IGCService_Stub.igcAddress_ArrayfromObject(IGCService_Stub.java:175)
at igcservice.IGCService_Stub.getAddress(IGCService_Stub.java:166)
at Displayable1.invokeServlet(Displayable1.java:93)
at Displayable1$1.run(Displayable1.java:66)

The line is:

Code:

private static igcAddress[] igcAddress_ArrayfromObject( Object obj[] ) {
if(obj == null) return null;
igcAddress result[] = new igcAddress[obj.length];
for( int i = 0; i < obj.length; i++ ) {
result[i] = new igcAddress();
Object[] oo = (Object[]) obj[i];
result[i].setFullname((String )oo[0]); //<----------- HERE!!
result[i].setId((String )oo[1]);
result[i].setNbhoodL((String )oo[2]);
result[i].setNbhoodR((String )oo[3]);
result[i].setHeight(((Integer )oo[4]).intValue());
}
return result;
}

I think it's a bug. Someone else with this problem?
Thanks!!
