[PATCH] Fix handling of default encoding style for chained mapping registries

[Scott Nichol <sn...@computer.org>]

Committers:

I believe I have located a bug in the current Apache SOAP source that prevents
the default encoding from being correctly applied.

The SOAPMappingRegistry class, a subclass of XMLJavaMappingRegistry, now support
chaining, i.e. an instance has a parent, with the parent being null for the
"root" instance.  When looking up a mapping, the chain is followed if necessary
to resolve the mapping.

The XMLJavaMappingRegistry class has a method setDefaultEncodingStyle, which
sets the default encoding style.  When this method is called on a
SOAPMappingRegistry instance, the default encoding style is set only for the
particular link in the chain.  It is *not* set for the parent (and recursively
for all parents).  This breaks the proper application of the default.

The attached patch properly overrides setDefaultEncodingStyle for
SOAPMappingRegistry.
