Hi, I already did this before I added the typeMapping to the example. It has to be something else but I can't figure out what the problem is.

Does anybody know why you don't need to specify the factories in the deployment descriptor? best regards, kris -----Original Message----- From: Kris Melotte Sent: Wednesday, February 20, 2002 6:25 PM To: [EMAIL PROTECTED] Subject: samples.encoding with samples.userguide5 problem Hello, 1. I tried the samples.encoding.TestSer example and this worked fine. 2. Next, I changed the samples.userguide5 example to use the Data custom mapping - I added a property data to the Order. bean with getter and setter - added this to Client.java: QName qnd = new QName("urn:BeanService","Data"); call.registerTypeMapping(samples.encoding.Data.class, qnd, new samples.encoding.DataSerFactory(), new samples.encoding.DataDeserFactory()); - added this to deploy.wsdd: <typeMapping qname="myNS:Data" xmlns:myNS="urn:BeanService" languageSpecificType="java:samples.encoding.Data" serializer="samples.encoding.DataSer" deserializer="samples.encoding.DataDeserFactory"/> 3. Next I deployed the service Then, the client gives this error: Error : java.lang.NullPointerException What am I doing wrong?
