We already have 
a)      Apache Axis2 and
b)      JAX-WS
        Web Services on a OpenVMS 4 core Itanium, Java 1.6.0_26 / Tomcat
5.5.26 server in use


BUT
for huge file transfers 
upload/download in a streaming mode 
not to run into heap space problems 
what is the best / robust technology to use 
a)      Apache Axis2, 
b)      JAX-WS or
c)      Apache CXF

Any hints or examples appreciated ! 

The current implementation is a JAX-WS MTOM enabled web service 
@javax.xml.ws.BindingType(value =
javax.xml.ws.soap.SOAPBinding.SOAP12HTTP_MTOM_BINDING)
which works nicely on a fast 8 core Itanium OpenVMS with java 1.6.0-p2
from HP
getting feed by a Vista Visual Studio C# WCF/.NET 4.0 Client (also MTOM
enabled)

The same service implementation (moved just the war file to the other
machine) 
fails on a slower 2 core Itanium OpenVMS with java 1.6.0-4 from HP, with
a " java out of heap space".

So I guess something is wrong with my upload design.
