一、实验环境

win2k + jdk1.6 + javee5.0 + Myeclipse5.1
jdk和javee5.0均可从
http://java.sun.com/javase/downloads/index.jsp
下载，安装文件名为
jdk-6-windows-i586.exe
java_ee_sdk-5_02-windows.exe
没有myeclipse的也可以用eclipse代替，只要ide能执行
ant脚本就可以.

二、第一个最简单的例子

jsee5安装以后会在系统中建立一个Application Server pe9，这是sun自带的网络服务器，
和tomcat、weblogic的性质类似。
在D:/Sun/SDK/samples/javaee5/webservices/hello-jaxws下有一个自带的web service入门例子,
(D:/Sun/SDK/为我机器上javaee5的安装路径)
我们就先实验它，来理解webservice的本质
1、把jdk的安装路径如D:/Java/jdk1.6.0/bin 加到系统的path环境变量中
2、运行sun自带的网络服务器，具体方法为
开始-> 程序-> Sun Microsystems-> Application Server PE 9-> Start Default Server
然后当弹出的cmd窗口中出现提示“按任意键继续时”输入回车，窗口会关闭，此时在浏览器输入
http://localhost:8080,应该出现如下内容：
Sun Java System Application Server Platform Edition 9.0
Your server is up and running!

说明服务器已经启动了

3、在Myeclipse打开刚才的例子目录D:/Sun/SDK/samples/javaee5/webservices/hello-jaxws
下的build.xml文件，这个一个ant脚本，具体含义我们以后再讲，现在先执行它
3、在build.xml文件中单击右键，在弹出菜单中选择 "run as "-> "1 ant build "，此时build.xml里的
内容会被执行，在Myeclipse的console中会输出:
buildfile: D:/Sun/SDK/samples/javaee5/webservices/hello-jaxws/build.xml
init:
compile-deploy-service:
[echo] d:/Sun/SDK
get-artifacts-windows:
get-artifacts-unix:
get-artifacts:
compile-client:
[javac] Compiling 1 source file to D:/Sun/SDK/samples/javaee5/webservices/hello-jaxws/build
run-client-windows:
[exec] Hello result = Hello Administrator!
run-client-unix:
run-client:
all:
BUILD SUCCESSFUL
Total time: 43 seconds

其中
[exec] Hello result = Hello Administrator!
的输出结果说明客户端调用服务器的webservice已经成功。
第一个例子就完成了。我们下面会对这个例子进行详细讲解.

/*title: web service入门学习笔记（三）、（四）

*/

三、WebService的本质

从搞c的程序员的眼光来看，webservice实际上就是用java实现的rpc(远端过程调用)，
或者说是dll的变形。服务器把它的接口对外发布成一个wsdl文件，客户端根据这个wsdl的内容生成
本地的代理类，再通过代理类调用远端的接口，代理再把接口的执行执行结果回传给客户端，
进行下一步处理。

四、例子源代码剖析

D:/Sun/SDK/samples/javaee5/webservices/hello-jaxws（以后简称为hello-jaxws）
项目里的源文件只有三个
hello-jaxws/src/endpoint/Hello.java 提供webservice的服务器端实现类
hello-jaxws/src/client/Client.java 调用webservice的客户端测试类
hello-jaxws/build.xml 自动编译的ant脚本

下面我们把这三个文件的内容看一下
1、服务器端的service实现类文件Hello.java，
/* src/endpoint/Hello.java文件的内容 */
package endpoint;
import javax.jws.WebService;

@WebService
public class Hello
{
public String getHello(String name)
{
return "Hello " + name + "! ";
}
}

有这个文件可以看出，编写一个service的实现类，把编写普通的java类
差不多，只不过又多了三点
①要在该类前一个@WebService说明，
②引入javax.jws.WebService;
③在公开的方法前加@WebMethod说明，如果不加的话，
所有的public方法都会自动变成service的对外接口.

2、客户端测试类的实现文件
/* src/client/Client.java文件的内容 */
package client;
import javax.xml.ws.WebServiceRef;
import endpoint.HelloService;
import endpoint.Hello;

public class Client
{
@WebServiceRef(wsdlLocation= "http://localhost:8080/Hello/HelloService?WSDL ")
static HelloService service;

public static void main(String[] args)
{
Client client = new Client();
client.doHello();
}

public void doHello()
{
try
{
Hello port = service.getHelloPort();
String ret = port.getHello(System.getProperty( "user.name "));
System.out.println( "Hello result = " + ret);
}
catch(Exception e)
{
e.printStackTrace();
}
}
}
客户端调用代码要点为:
①导入WebServiceRef包
import javax.xml.ws.WebServiceRef;
②导入本地生成的stub类，另外编译时也要指明stub类的路径
import endpoint.HelloService;
import endpoint.Hello;
③指明服务器的wsdl路径
@WebServiceRef(wsdlLocation= "http://localhost:8080/myhello/HelloService?WSDL ")
④声明一个静态的service对象
static HelloService service;
⑤对要调用的远程方法声明一个代理对象，通过代理来调用真正的远程方法
Hello port = service.getHelloPort();
String ret = port.getHello(System.getProperty( "user.name "));

3、ant 脚本build.xml

<?xml version= "1.0 " encoding= "UTF-8 "?>
<project name= "hello-jaxws " default= "all " basedir= ". ">

这个脚本有许多在windows平台用不到的步骤，下面我们对其进行改造，把它精简一下.

*/

五、精简后的ant脚本

1、卸载webservice
执行原build.xml里的clean和 undeploy任务，把安装好的webservice删除掉，具体办法为：
(1)在myeclipse里打开build.xml文件
(2)在build.xml文件里单击右键菜单中的 " "run as "-> "2 ant build... " ",
(3)在弹出的对话框中只选择clean和undelpoy任务。然后单击 "run "按钮。
此时再访问http://localhost:8080/Hello/HelloService?WSDL,出现http 404错误，说明卸载成功

2、简化后的脚本内容，在hello-jaxws目录下新建一个buildtest.xml文件，内容为
<?xml version= "1.0 " encoding= "UTF-8 "?>
<project name= "hello-jaxws " default= "all " basedir= ". ">

<property name= "javaee.home " value = "d:/Sun/SDK "/>
<property name= "javaee.domaindir " value= "${javaee.home}/domains/domain1 "/>
<property name= "javaee.server.name " value= "localhost "/>
<property name= "javaee.server.port " value= "8080 "/>


<property name= "autodeploydir " value= "${javaee.domaindir}/autodeploy "/>
<property name= "classesdir " value= "./build "/>


<path id= "classpath ">
<pathelement location= "${javaee.home}/lib/j2ee.jar "/>
<pathelement location= "${classesdir} "/>
</path>

<target name= "all " depends= "run-client ">

</target>

<target name= "run-client " depends= "compile-client,run-client-windows " />


<target name= "run-client-windows ">
<exec executable= "${javaee.home}/bin/appclient.bat " dir= "${classesdir} ">
<arg value= "client.Client " />
</exec>
</target>



<target name= "compile-client " depends= "get-artifacts ">
<javac srcdir= "./src/client " destdir= "${classesdir} ">
<classpath refid= "classpath " />
</javac>
</target>

<target name= "get-artifacts " depends= "compile-deploy-service,get-artifacts-windows "/>


<target name= "get-artifacts-windows ">
<exec executable= "${javaee.home}/bin/wsimport.bat ">
<arg line= "-keep -d ${classesdir} http://${javaee.server.name}:${javaee.server.port}/Hello/HelloService?WSDL " />
</exec>
</target>



<target name= "compile-deploy-service ">
<mkdir dir= "${classesdir} " />
<echo message= "${javaee.home} " />
<javac
srcdir= "./src "
includes= "endpoint/** "
destdir= "${autodeploydir} "
classpath= "${javaee.home}/lib/j2ee.jar "
/>
<waitfor maxwait= "100 " maxwaitunit= "second ">
<or>
<available file= "${autodeploydir}/endpoint/Hello.class_deployed "/>
<available file= "${autodeploydir}/endpoint/Hello.class_deployFailed "/>
</or>
</waitfor>
<condition property= "deploy_succeeded ">
<available file= "${autodeploydir}/endpoint/Hello.class_deployed "/>
</condition>
<condition property= "deploy_failed ">
<available file= "${autodeploydir}/endpoint/Hello.class_deployFailed "/>
</condition>
</target>


<target name= "clean ">
<delete dir= "${classesdir} "/>
</target>

<target name= "restore ">
<delete>
<fileset dir= "${autodeploydir}/endpoint " includes= "Hello*.* "/>
</delete>
</target>

<target name= "undeploy ">
<antcall target= "restore "/>
</target>
</project>

3、运行结果
在myeclipse里执行这个刚才编写的buildtest.xml脚本，console里的输出为
Buildfile: D:/Sun/SDK/samples/javaee5/webservices/hello-jaxws/buildtest.xml
compile-deploy-service:
[mkdir] Created dir: D:/Sun/SDK/samples/javaee5/webservices/hello-jaxws/build
[echo] d:/Sun/SDK
[javac] Compiling 1 source file to D:/Sun/SDK/domains/domain1/autodeploy
get-artifacts-windows:
get-artifacts:
compile-client:
[javac] Compiling 1 source file to D:/Sun/SDK/samples/javaee5/webservices/hello-jaxws/build
run-client-windows:
[exec] Hello result = Hello Administrator!
run-client:
all:
BUILD SUCCESSFUL
Total time: 50 seconds

也执行成功

*/

六、一个通用的ant脚本

1、脚本内容
上面的buildtest.xml脚本虽然对原始的build.xml做了精简，但是还不够通用，
比如服务器的类名和方法名等等都写死了，显然还不适合我们的需要，于是我又写了一个相对通用的脚本
mybuild.xml，内容如下
<?xml version= "1.0 " encoding= "UTF-8 "?>

<project name= "hello-jaxws " default= "all " basedir= ". ">

<property name= "javaee.home " value = "d:/Sun/SDK "/>
<property name= "javaee.domaindir " value= "${javaee.home}/domains/domain1 "/>
<property name= "javaee.server.name " value= "localhost "/>
<property name= "javaee.server.port " value= "8080 "/>


<property name= "autodeploydir " value= "${javaee.domaindir}/autodeploy "/>
<property name= "classesdir " value= "./build "/>


<path id= "classpath ">
<pathelement location= "${javaee.home}/lib/j2ee.jar "/>
<pathelement location= "${classesdir} "/>
</path>


<property name= "serviceclass " value= "Hello " />
<property name= "serverclasspath " value= "endpoint " /> 

<property name = "clientclass " value= "Client "/>
<property name = "clientclasspath " value= "client "/> 

<property name= "wsdluri "
value= "http://${javaee.server.name}:${javaee.server.port}
/${serviceclass}/${serviceclass}Service?WSDL " />

<target name= "all " depends= "run-client ">

</target>

<target name= "run-client " depends= "compile-client,run-client-windows " />


<target name= "run-client-windows ">
<exec executable= "${javaee.home}/bin/appclient.bat " dir= "${classesdir} ">
<arg value= "${clientclasspath}.${clientclass} " />
</exec>
</target>



<target name= "compile-client " depends= "get-artifacts ">
<javac srcdir= "./src/${clientclasspath} " destdir= "${classesdir} ">
<classpath refid= "classpath " />
</javac>
</target>

<target name= "get-artifacts " depends= "compile-deploy- ②asadmin deploy --user admin --password laomailaomai --host localhost --port 4848 --contextroot hello --upload=true --target server
service,get-artifacts-windows "/>


<target name= "get-artifacts-windows ">
<exec executable= "${javaee.home}/bin/wsimport.bat ">
<arg line= "-keep -d ${classesdir} ${wsdluri} " />
</exec>
</target>


<target name= "compile-deploy-service ">
<echo message= "${javaee.home} " />
<javac
srcdir= "./src "
includes= "${serverclasspath}/** "
destdir= "${autodeploydir} "
classpath= "${javaee.home}/lib/j2ee.jar "
/>
<waitfor maxwait= "100 " maxwaitunit= "second ">
<or>
<available file= "${autodeploydir}/${serverclasspath}/${serviceclass}.class_deployed "/>
<available file= "${autodeploydir}/${serverclasspath}/${serviceclass}.class_deployFailed "/>
</or>
</waitfor>
<condition property= "deploy_succeeded ">
<available file= "${autodeploydir}/${serverclasspath}/${serviceclass}.class_deployed "/>
</condition>
<condition property= "deploy_failed ">
<available file= "${autodeploydir}/${serverclasspath}/${serviceclass}.class_deployFailed "/>
</condition>
</target>


<target name= "clean ">
<delete dir= "${autodeploydir}/${serverclasspath} "/>
<delete dir= "${classesdir}/${serverclasspath} "/>
<delete dir= "${classesdir}/${clientclasspath} "/>
</target>
</project>

2、脚本的使用方式
以后再写自己service时，只要按实际情况改变以下4条语句中的value值就可以了
<property name= "serviceclass " value= "Hello " />
<property name= "serverclasspath " value= "endpoint " />
<property name = "clientclass " value= "Client "/>
<property name = "clientclasspath " value= "client "/>

*/

七、命令行开发过程

通过以上的学习，我们知道如何在ant脚本和ide环境中开发一个简单的webservice.
但是作为搞技术的人特别是搞c的人来看，上面的过程隐藏了太多的东西，
对我们有钻研精神的人，自然就想搞清楚脚本背后的过程。
假设我们的机器上没有ide环境和ant工具，
我们如何“手工”编译出自己的webservice呢？
这就是本节要讲述的内容--只用命令行工具开发webservice.

0、设置环境变量
把jdk和javaee的路径如
D:/Java/jdk1.6.0
D:/Sun/SDK/bin加到系统的path变量中去

1、建立项目目录
首先建立一个项目的目录，名为WebTest，项目目录下又包含三个子目录
src/ 本目录用于存放源代码，
build/ 本目录用于存放输出的文件
deploy/ 本目录用于对服务器打包

2、编写服务器类实现文件
在项目的src目录下建立一个个子目录endpoint，
在这个endpoint子目录下新建一个Hello.java文件，内容如下

/*src/endpoint/Hello.java文件
提供webservice的服务器端实现类
*/
package endpoint;

import javax.jws.WebService;
import javax.jws.WebMethod;

@WebService
public class Hello
{
@WebMethod
public String getHello(String name)
{
return "Hello " + name + "! ";
}
}
3、编译服务器类
①在build目录下建立一个子目录classes
②在命令行执行如下命令
cd WebTest ;进入项目目录
javac -classpath d:/Sun/SDK/lib/javaee.jar -d ./build/classes src/endpoint/Hello.java ;编译服务器类
执行完后会产生一个build/classes/endpoint/Hello.class文件

4、生成wsdl文件
①在build目录下建立一个子目录generated
②生成wsdl文件,执行
wsgen -cp ./build/classes -keep -d ./build/classes -r ./build/generated -wsdl endpoint.Hello

执行完成会在./build/generated产生两个文件
HelloService.wsdl
HelloService_schema1.xsd
并且在/build/class/endpoint下建立一个jaxws目录，下面有4个文件
GetHello.java
GetHello.class
GetHelloResponse.java
GetHelloResponse.class

这些文件与与前面所说的ant脚本中生成的
D:/Sun/SDK/domains/domain1/generated/ejb/j2ee-modules/endpoint_Hello/endpoint/jaxws
下的文件相同

5、将服务器打包，做成war文件
①建立打包所需要的目录
在项目的deploy目录下建立一个子目录/WEB-INF，
WEB-INF子目录下再建立两个子目录
classes/ 用于存放服务器端类
wsdl/ 用于存放wsdl文件

②将各输出文件或目录拷贝到相应的目录下
(1)把build/classes/endpoint整个目录拷贝到deploy/WEB-INF/class目录下
(2)把build/generated目录下的两个文件
HelloService.wsdl、HelloService_schema1.xsd拷贝到
deploy/WEB-INF/wsdl目录下
③在deploy/WEB-INF/ 目录下新建一个web.xml文件，内容为
<?xml version= "1.0 " encoding= "UTF-8 "?>
<web-app xmlns= "http://java.sun.com/xml/ns/javaee "
xmlns:j2ee= "http://java.sun.com/xml/ns/javaee "
xmlns:xsi= "http://www.w3.org/2001/XMLSchema-instance " version= "2.5 "
xsi:schemaLocation= "http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd ">
<description> WebTier for the Hello Service </description>
<display-name> HelloWAR </display-name>
<servlet>
<description> Endpoint for Hello Web Service </description>
<display-name> HelloWebService </display-name>
<servlet-name> Hello </servlet-name>
<servlet-class> endpoint.Hello </servlet-class>
<load-on-startup> 0 </load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name> Hello </servlet-name>
<url-pattern> /HelloService </url-pattern>
</servlet-mapping>
<session-config>
<session-timeout> 54 </session-timeout>
</session-config>
</web-app>
④将service打包,执行
(1)cd WebTest/deploy ;进入打包目录
(2)jar cvf hello.war * ;将当前目录下的所有内容打包到hello.war文件中

6、将service 类发布到网络服务器上
①启动sun 服务器
方法为
开始-> 程序-> Sun Microsystems-> Application Server PE 9-> Start Default Server
②在项目目录下建立一个passwd文件，内容是sun服务器admin用户的密码，例如
AS_ADMIN_PASSWORD=testtesttest
③将hello.war发布到服务器上，执行
(1)cd WebTest ;进入项目目录
(2)发布服务器包，注意这个命令是在一行执行的，
我为了书写方便而断行。分号后面是注释
asadmin deploy
--user admin ;管理员用户名
--passwordfile passwd ;密码文件名，就是我们刚才写的passwd文件
--host localhost
--port 4848 ;管理端口号
--contextroot myhello ;上下文根名称
--upload=true
--target server
deploy/hello.war

④在浏览器中输入地址
http://localhost:8080/myhello/HelloService?WSDL，
如果浏览器能显示出正确的内容，就说明成功。

7、生成客户端的stub类
①在项目的build/classes目录下建立一个stub子目录
②执行
(1)cd WebTest ;进入项目子目录
(2)wsimport -keep -d ./build/classes/stub http://localhost:8080/myhello/HelloService?WSDL

执行完成后会在build/classes/stub下建立一个endpoint目录，下面有这些文件
GetHello.java
GetHelloResponse.java
Hello.java
HelloService.java
GetHello.class
GetHelloResponse.class
Hello.class
HelloService.class
ObjectFactory.class
ObjectFactory.java
package-info.java
package-info.class
这些文件和ant脚本中import执行的结果一样

8、编写客户端测试程序

在项目的src目录下建立一个子目录client，在这个目录下面建立一个
Client.java文件，内容为

// src/client/Client.java文件调用服务器提供的webservice的测试类
package client;

import javax.xml.ws.WebServiceRef;
import endpoint.HelloService;
import endpoint.Hello;

public class Client
{
@WebServiceRef(wsdlLocation= "http://localhost:8080/myhello/HelloService?WSDL ")
static HelloService service;
public static void main(String[] args)
{
Client client = new Client();
client.doHello();
}
public void doHello()
{
try
{
Hello port = service.getHelloPort();
String ret = port.getHello(System.getProperty( "user.name "));
System.out.println( "Hello result = " + ret);
}
catch(Exception e)
{
e.printStackTrace();
}
}
}

9、编译客户端程序
执行
(1)cd WebTest ;进入项目目录
(2)javac -classpath ./build/classes/stub;d:/Sun/SDK/lib/javaee.jar;d:/Sun/SDK/lib/appserv-ws.jar -d ./build/classes/stub src/client/Client.java
执行成功后会在F:/exercise/java/WebTest/build/classes目录下建立一个
client目录，下面有一个Client.class文件

10、运行客户端程序
(1)cd WebTest/build/classes/stub ;进入client的上级目录
(2)set APPCPATH=. ;设置环境变量APPCPATH，不然运行appclient程序时会出一堆莫名奇妙的错误
(3)> appclient client.Client运行测试程序，结果为
Hello result = Hello Administrator!
执行成功

八、小结

开发webservice的基本步骤为
1、编写服务器端，要点有
①导入WebService包和WebMethod包
import javax.jws.WebService;
import javax.jws.WebMethod;
②实现的服务类前加@WebService符号
③为了代码清晰,类提供的公开方法前加@WebMethod符号,这个不写对编译也没影响，

2、编译服务器端，要点为
①javac命令的classpath选项中要有javaee.jar的路径，如
javac -classpath d:/Sun/SDK/lib/javaee.jar -d ./build src/endpoint/Hello.java
②用wsgen命令生成wsdl文件.
③将服务器端打包
注意如果是sun的服务器，那么把service类直接编译到
javaee5安装目录/domains/domain1/autodeploy下，可以自动完成②和③的工作。
我们介绍的sun自带的入门脚本就是这么做的。
3、在客户端机器上自动生成stub类,要点为
①客户机上必须也装有jdk和javaee5
②用wsimport工具将服务器传过来的wsdl文件转换成本地的stub类
4、编写客户端调用代码，要点:
①导入WebServiceRef包
import javax.xml.ws.WebServiceRef;
②导入本地生成的stub类，如
import endpoint.HelloService;
import endpoint.Hello;
③指明服务器的wsdl路径
@WebServiceRef(wsdlLocation= "http://localhost:8080/myhello/HelloService?WSDL ")
④声明一个静态的service对象
static HelloService service;
⑤对要调用的远程方法声明一个代理对象，通过代理来调用真正的远程方法
Hello port = service.getHelloPort();
String ret = port.getHello(System.getProperty( "user.name "));
5、编译客户端调用程序，注意classpath参数中要有
①stub类的路径
②javaee.jar的路径
③appserv-ws.jar的路径

6、用appclient执行客户端程序，要点为
①进入到客户端程序的上级目录
②把APPCPATH的值设置为当前目录 " . "
③appclient的第一个参数为客户端程序名，
后面的参数是传给客户端程序本身的命令行参数。
