Server-Side Slice-to-Java Mapping

The mapping for Slice data types to Java is identical on the client
对于Java来讲，Slice数据类型映射在客户端和服务端是一样的。

意思就是，所有的Client-Side Slice-to-Java Mapping底下的内容也都
Slice-to-Java Mapping also applies to the server side. However, for
适用服务端。
the server side, there are a few additional things you need to know
然而，对于服务端来讲，有几点补充说明你需要知道。
— specifically how to:
具体如下：
- Initialize and finalize the server-side run time
初始化和定义服务端，使它运行起来
- Implement servants
实现servants
- Pass parameters and throw exceptions
传递参数抛出异常
- Create servants and register them with the Ice run time
创建servants并且注册运行时的Ice
Because the mapping for Slice data types is identical for clients
由于这Slice数据类型映射对于服务端和客户端是一样的，
and servers, the server-side mapping only adds a few additional
所以这服务端只需要添加一下对客户端的补充机制：
mechanisms to the client side: a small API to initialize and finalize
有些API用来初始化和实现这运行状态
the run time, plus a few rules for how to derive servant classes
加上一些规则为了如何去驱动servant类从skeletons并且如何注册
from skeletons and how to register servants with the server-side
servants用这运行的服务端
