Subject RE: INOUT / OUT parameters
Date Fri, 29 Nov 2002 08:49:47 GMT
Brian told me that Call.getOutputParameters should return a map with the
parameter names as strings.

According to the specification, he is right :
"
getOutputParams
public java.util.Map getOutputParams()
Returns a Map of {name, value} for the output parameters of the last invoked
operation. 
The parameter names in the returned Map are of type java.lang.String.
Returns:
Map Output parameters for the last Call.invoke(). Empty Map is returned if
there are no output parameters
"

But we return a map with the parameter names as QNames

So, are we JAX-RPC compliant here ?
