You must install the Android SDK before you can develop apps.
Windows、Intel-based Mac OS X、i386-based Linux operating systems.
下载并解压后，更新PATH环境变量。
下载和安装SDK的前提条件：
Android SDK支持一下操作系统：
（1）Windows XP（32-bit），Vista（32- or 64-bit），or Windows 7（32- or 64-bit）.
（2）Mac OS X 10.5.8 or later（x86 ...
Apache Axis™ is a second generation SOAP engine, the successor to the Apache SOAP project, itself based on the original SOAP4J code that IBM contributed to Apache in April 2000. In contrast to its predecessor, Axis is fully WSDL aware. It also supports the JAX-RPC API.
Today, Apache Axis is to a la ...
Metro是Java web service specifications的开源参考实现。
它由JAX-WS、JAXB构成，并且还支持legacy JAX-RPC APIs。
Metro stack是由GlassFish社区搞的，但它也可以在GlassFish之外使用（JavaEE或JavaSE环境）
要调用一个document style web service里的一个操作，你只需要发送input message里仅有的那个part就行了。
注意，它不会发送operation name。那么如果在该web service中有多个operations，它又是怎么决定调用的是
哪个operation呢？这种情况下，它可以看出来input message是一个<concatRequest>或是一个<someElement>。那么假如都叫<someElement>呢？那就出错了，无法工作。
That is, the input message will contain a single part only which is well defined in a schema.
RPC style web service和document style web service的不同之处：The significant difference is that the former
can't be validated with a schema while the latter can. Therefore, document style web service is becom ...
That is, the operation QName and the names of the parts are used to create the input message.
Getting ready for the SDK
over 4 GB.
It gives you the tools you need to program（Xcode 4）,debug（Instruments）,and test（Simulator）your
iPhone, iPod Touch, and iPad code.
Note: You must have an Intel-based Apple Macintosh running Mac OS X 10.6.5 or higher to use the SDK.

方法1：用mysqladmin命令在命令行指定密码。
shell> mysqladmin -u user_name -h host_name password "newpwd"
方法2：执行set password语句。下例中将账号'jeffrey'@'%'的密码改为'biscuit'。
mysql> set password for 'jeffrey'@'%'=PASSWORD('biscuit');
如果是修改自己的密码，可以省略for语句：
mysql> set password=PASSWORD('biscuit');

（1）Your service must be accessible by different languages and platforms.
（2）Your service must be able to go through firewalls.
Given these requirements, the best solution is to provide a so-called "web service".
For example, you may make a web service accessible on the host www.ttdev ...
Data binding
Data binding is the key for any web service development. Data binding means
mapping between Java objects and XML elements. As we know, with web service,
messages are exchanged as XML artifacts. So there has to be some way to convert
these XML into Java objects and vice versa for ...
Service model
The Service model, in a true sense, models your service. It is a framework of
components that represents a service in a WSDL-like model. It provides functionality
to create various WSDL elements such as operations, bindings, endpoints,
schema, and so on.
The components of ...
Messaging and Interceptors
One of the important elements of CXF architecture is the Interceptor components.
Interceptors are components that intercept the messages exchanged or passed
between web service clients and server components. In CXF, this is implemented
through the concept of Interce ...
Frontend
CXF provides the concept of frontend modeling, which lets you create web services
using different frontend APIs. The APIs let you create a web service using simple
factory beans and JAX-WS implementation. It also lets you create dynamic web
service clients. The primary frontend supp ...
Yellowdog Updater, Modified(YUM)是一个RPM包管理工具。它使用repositories。Repositories可以在本地目录、FTP服务器或者甚至HTTP。
如果你溢出一个包，同时又有其他包依赖于该包，则YUM将帮助你解决此事。首先，YUM将找出你要移除的包的所有依赖包，然后，如果你确定要移除包，YUM会先移除
那些依赖包，最后再移除你要移除的包。
命令格式：
yum command packagename[ packagename1 packagename2 .. packagenameN]
一、安装包
yum install ...
当JVM加载classes时，它必须跟踪关于这些classes的特定的元数据。这样的元数据被放在一个独立的heap space中。Java 7里叫permgen，Java 8里叫metaspace。
Permgen和metaspace不是同一个东西。java 7里，permgen包含了一些杂项对象（和class data无关）；它们在Java 8里被移到了平常的heap中去了。Java 8还从根本上改动了保存在
该特殊区域里的元数据的类型。作为一般用户，我们只需要知道permgen和metaspace存储了一些class相关的数据，在特定的情况下，这些区域的size需要被调整。
