I'm trying to set up a 2-way SSL connection to an external web service using Oracle Fusion Middleware (a.k.a. SOA Suite). I've googled and even bing'ed my brains out and have found lots of good documentation on creating the JKS, and even some details on adding <property name="oracle.soa.two.way.ssl.enabled">true</property> to the binding.ws element in the composite's XML (all of which I've done). What I haven't found/figured out is how to explicitly state what alias from the JKS to use for that particular connection. This is especially problematic because depending on some key parameters, I need to use one cert rather than another one when establishing that connection (same endpoint, have to pick from 2 different certs). How/Where do I set this up? Is it in BPEL, in the composite? etc.
I've seen code on how to do this in straight Java, but given the visual nature of BPEL and the Composite, I don't know how to tell the system to use a specific key from a key store.
