The problem is caused by another JAR in the classpath with Apache SOAP classes which are conflicting with the WebSphere Application Server SOAP implementation. The JAR is likely to have these classes which do not come with the SOAP package shipped with IBM® WebSphere® Application Server:

org.apache.soap.encoding.SOAPMappingRegistry
org.apache.soap.encoding.soapenc.CleanSerializer
org.apache.soap.encoding.soapenc.CollectionSerializer
