[jira] Commented: (AXISCPP-545) getNamespacePrefix() API in Call class does not return NULL for non existing namespace URI.

Mark Whitlock commented on AXISCPP-545:
---------------------------------------

Having investigated it, I believe that Call::getNamespacePrefix is behaving correctly or at least it is doing what it was intended to do.

The problem it is trying to solve happens when the Axis engine or a client application has a namespace that it is going to use for an attribute or a headerblock or something and it wants to get a new prefix for that namespace that hasn't been used before. So if that namespace is already associated with a prefix, Call::getNamespacePrefix returns that prefix. If the namespace is not associated with any prefix, Call::getNamespacePrefix creates a new prefix. The prefixes it creates all start with ns and end with a number that it increments every time to make sure it never returns the same prefix for different namespaces.

The soap serializer handles standard namespaces differently - those namespaces that are not defined by the application. So Call::getNamespacePrefix doesn't know anything about those and so will create a new prefix for them if they are passed in.

I have run DynamicGetNamespacePrefixTest and this is the behaviour you are seeing. Basically the test needs to be rewritten. I am happy to rewrite the test if you would like, just let me know. I will add in better comments in the Call::getNamespacePrefix API docs to explain all this. Please let me know what you would like me do with this JIRA. Thanks.

> Instead of NULL getNamespacePrefix() API returns some prefix for non existing namespace URI. Also API does not return correct prefix for existing namespace URIs.
> DynamicGetNamespacePrefixTest addresses these issues.
