PI 7.31 EHP1 SOAP-> Java proxy config question

Hi,

I'm struggling to implement the SOAP->Integration Server-> Java Proxy scenario in Netweaver PI 7.31 EHP 1 Dual Stack. Seems like the various documents I read on configuring this scenario are incomplete and sometimes contradictory. So I have a couple of questions.

1) I have an Inbound service defined in ESR. Does it need to be use the Interface pattern "Stateless (XI30-Compatible)" or is Stateless sufficient? I believe I've read that in XI30-Compatible is for legacy compatibility and not necessary in 7.31.

2) If I use the Stateless interface pattern, do I use the WS adapter for the Integration Server to Java proxy communication? If XI30-Compatible is used, then I understand I need an XI adapter.

Thanks,

Steve
