Stub.getHeader(namespace, partname) in axis1.1

[Nan Xiong]

Hello,
I have a .NET web services that passes session id (a string) in the soap header, we 
were able to use 
Stub.getHeader(...) and Stub.setHeader() to make axis client talking to the .NET 
services using axis1.1 RC2, 
however, in axis1.1 final release, getHeader returns null.  Anybody has the same 
problem?  
Can someone confirm this is a bug?  or intentionally disabled?  Whats the alternatives 
to access the header? (client handler?)
Thanks in advance
Nan
