Invoking bpel process from java in oracle soa/bpm 11g

Question

Hi,
We have some java code to invoke bpel process in oracle BPM 10g following the instructions in http://download-east.oracle.com/docs/cd/B14099_19/integrate.1012/b14448/invoke.htm.
Basically the steps are:
1) get a Locator (com.oracle.bpel.client.Locator)
2) get IDeliveryService (com.oracle.bpel.client.delivery.IDeliveryService) reference from locator
3) call IDeliveryService method request or post with input message and get the response back.
Recently we want to migrated from oracle bpm 10g to oracle soa/bpm 11g. But I can not find the similar API in 11g. It seems now some adapter/binding need to be added in exposed service lane in soa composite view, for example, ADF-BC, direct binding etc, in order to allow java to invoke a bpel process. Here are two very useful links from Edwin about the detail how this is implemented.

My question is:
1) what are the choices and the official/best way to invoke a bpel process in oracle soa/bpm 11g from java?
2) does user need to add an adapter/binding in exposed service lane in order to let the bpel service be called in java?
3) what is the real difference between a bpm application and soa application in 11g?
I will really appreciate any expert's opinion.
Thanks,
Bin

Thanks for your reply and confirmation, really appreciate it.
Yes, I found the difference of the invoking process API and was able to invoke bpel process using direct and ADF-BC binding by following Edwin's blog. But I have not found any official reference to compare this API difference between 10g and 11g ( I will mark this question as answered if anyone can find an official source from oracle, need to prove it to the team). The API to work with human task workflow seems pretty much the same between 10g and 11g.
