Service Invocation with strange namespace declaration
Hi,
I have a problem with the messages, which are sent by ODE. There's a strange setting of the namespaces. The following example is taken from my process:
<startProg xmlns="http://api.milling/">
<arg0 type="p0:AnyTypeDataObject">1</arg0>
<mil:arg1 xmlns:mil="http://api.milling/">10000</mil:arg1>
</startProg>
All elements are defined in the same namespace (http://api.milling/) and the Message sent is also correct xml. But it is not nice. The parent element has a namespace declaration, the child not (because it needs not) and the second child has a namespace declaration with prefix. I need the message in a fomat like:
<api:startProg xmlns:api="http://api.milling/">
<arg0>1</arg0>
<arg1>10000</arg1>
</api:startProg>
The Parent has a namespace and prefix, and the cildren do not. The reason why i need it is, that the service (a tuscany service) does not recognize any arguments otherwise.
Could anybody please help me?
Thank you very much in advance...

It's going to be hard to fix on our side unless someone is interested in
developing namespace optimizations before sending a message. The
multiplication of namespace declarations that you're seeing is the result of
assignments, as elements are copied from a document to another. Most XML
APIs don't do any namespace consolidation so we don't either.
I would ask on the Tuscany side why they refuse the message, it is valid XML
as you mentioned.
