Subject [jira] Commented: (AXIS-1308) Axis 1.2 beta and .NET 1.1: Problem with arrays
Date Thu, 11 Nov 2004 15:19:37 GMT
     [ http://nagoya.apache.org/jira/browse/AXIS-1308?page=comments#action_55353 ]
     
Tom Jordahl commented on AXIS-1308:
-----------------------------------

I also see this regression from Axis 1.1 to 1.2 in my product test suite.  The problem is
that the .NET WSDL specifically says that the arrayType should be xsd:string, and for rpc/encoded
services, Axis always prefers the soapenc types.

The root cause of this is that changes Glen made to the TypeMapping system which made it more
sane.  We used to have the SOAP encoded types registered in the DefaultTypeMappingImpl class.
 They were registered first if the encoded flag was NOT set and last if it WAS set. Since
"last one registered wins", this had the effect of preferring soapenc or xsd types in certain
situations.

This is further complicated by the fact that the code is set up to only have *one* instance
of the default type mapping.  We don't really accomplish that very well.

What we really have are *many* default type mappings, depending on lots of things.  There
is SOAP encoded, Literal, JAX-RPC 1.1(lots of types mapped to string instead of Axis custom
classes) and maybe more.

problems.

> I don't know, if this is a bug in Axis or .NET, but I think the interop is very important,
so even a workaround in Axis for a .NET bug should be considered, until MS fixes their bug.
