-----------------------------------------

Hello,

I got an answer on issue:
https://issues.apache.org/jira/browse/WSCOMMONS-327

I submit a patch that changes the way serialization occurs in the generated Stubs/Skeleton.
Patch is on AXIS2 XMLBeans module:
\modules\xmlbeans\src\org\apache\axis2\xmlbeans\template\XmlbeansDatabindingTemplate.xsl

The patch requires an upgrade to XMLBeans 2.4.0 otherwise an exception will occur (java.lang.IllegalArgumentException: Local name may not be null or empty) due to a Bug in XMLBeans:
http://forum.springframework.org/showthread.php?t=43958

Using this patch you will notice that namespaces are written at the beginning and that prefixes are used in all the document, I chose to set the following options on XMLBeans to reduce at max the message size:
xmlOptions.setSaveNoXmlDecl();
xmlOptions.setSaveAggressiveNamespaces();
xmlOptions.setSaveNamespacesFirst();

Hope you can take this patch into account soon because it is rather critical in terms of network traffic.

> When using XMLBeans as databinding layer.
> XML Requests and responses are very verbose due to same Namespaces being declared and redeclared.
> Example:
> <?xml version='1.0' encoding='UTF-8'?><soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"><soapenv:Body><v1:getLocatedProducts xmlns:v1="http://v1.product.ws.store.kingfisher.com"><v1:param0><xsd:callType xmlns:xsd="http://data.v1.product.ws.store.kingfisher.com/xsd">1</xsd:callType><xsd:familyCode xmlns:xsd="http://data.v1.product.ws.store.kingfisher.com/xsd">1</xsd:familyCode><xsd:moduleCode xmlns:xsd="http://data.v1.product.ws.store.kingfisher.com/xsd">1</xsd:moduleCode><xsd:subFamilyCode xmlns:xsd="http://data.v1.product.ws.store.kingfisher.com/xsd">1</xsd:subFamilyCode></v1:param0></v1:getLocatedProducts></soapenv:Body></soapenv:Envelope>
> You see that http://data.v1.product.ws.store.kingfisher.com/xsd is declared 4 times instead of one.
