We have recently migrated our JAX-RPC web services from Websphere 5.1 to 7.0. The web services have not changed during the migration and the WSDL files for both versions are identical. However, there is one difference in the web service response that is causing problems for the client. Apparently there is a namespace prefix (p909) added for the elements that originally did not have any prefix. This prefix is not in any of the WSDL files nor is it part of the request. It just appears out of nowhere.
Does anyone know why this prefix is being added and how to prevent it? Could it be a Websphere setting?
