It's actually easier than you think. Libraries like CXF have taken care of
the dirty work. You don't really have to write the wsdl. And the client stub
can be generated automatically.

Jersey 2.0加入了对Async的支持，但是一般情况下不需要用。
https://jersey.java.net/documentation/latest/async.html
“ This model (Synchronous mode) is typically sufficient for processing of
requests for which the processing resource method execution takes a
relatively short time. However, in cases where a resource method execution
is known to take a long time to compute the result, server-side asynchronous
processing model should be used. ”

I am not sure if there are any good use case of server side async. For
server to server communication, you can achieve the same goal by doing the
processing in a separate thread, and calling back on the caller's web
service (or use MQ). A connection doesn't need to be kept open during the
processing, I am sure that will be more efficient.
For client-server communication, the connection can easily time out, and the
result will be lost. It's much better to save the result and allow the
client to poll periodically or do long poll. Then fetch the result when
state is changed.

这个goodbug可能说的更清楚。node里面任何api都是non-blocking的。因此你可以同时
处理大量的request。而且只需要一个thread，所以没有context switch， thread
stack，节省CPU和memory a lot。简单来说就是可以把CPU用到极致。

seems nodes is using Asynchronous I/O so that no thread is idle to fully
utilize the resource. It's similar as what Jersey 2.4 can do as server side
async. But from caller, it doesn't see any difference. It is still a
blocking call.

现在所谓“standard based” SOA和Enterprise Integration还是SOAP/WSDL/BPEL那一
套。不新潮不代表legacy。SOAP和REST都会长期存在。
都没啥难的，SOAP/RESTful都算计算机工作中最简单的了吧。
其实SOAP和REST不是并列词汇。REST是architecture style，与之并列的是RPC。SOAP
是spec。把它们俩列在一块就像问“你觉的iOS好呢还是Nexus 5好” :)

你吧SOAP也好，Rest也好，想象成调用SDK的API，从一个固定语言，变成了任意语言。
这些东西，找到了specification，看两遍，写俩程序就OK了。
不过，现在大趋势是RestFUL。XML会慢慢变成大数据feed和consume用，而这种需要快
捷的通信JSON还是更好一些，负担小！
