Thanks for the suggestion, Romulus - I have tried this workaround, but it doesn't look like it is going to give me what I want. When I follow this model, Axis generates an additional class called "_void" and then my methods return that object, rather than actually returning void. It seems like the only way to generate methods that truly return void rather than returning an Object of some sort is to define an empty message with no parts in the WSDL, but then the service doesn't know what to do with it at runtime...And therein lies my problem. Regards, Sabrina

CIV Sys Eng Branch 1B 9512 [mailto:[EMAIL PROTECTED] Sent: Monday, June 14, 2004 11:44 AM To: [EMAIL PROTECTED] Subject: Problems returning void in document-literal operation I have seen a few postings about this problem, but no resolution. I am working on a document-literal service and several of the operations should have a "void" return type. We are following the top-down model, writing the WSDL first and then using WSDL2Java to generate the Java classes. For the operations that should return "void", I have defined the following message in the WSDL (no parts): <wsdl:message name="EmptyMessageResponse" /> Axis has no problem generating the Java code - The methods using this response message are correctly generated as returning "void". But when I try to call the service, I get the following error: org.xml.sax.SAXException: Deserializing parameter 'ModifyUnofficialRecordRequestResponse': could not find deserializer for type {http://xml.apache.org/axis/}Void All of my operations that do not return void seem to be working just fine. Is this an Axis bug, or do I need to do something special to "massage" the WSDL or WSDD to get this to work? I am using Axis 1.1. Any help would be greatly appreciated! Regards, Sabrina
