关键�? webservice

1. Introduction
This document will outline the process of developing a JAX-WS web service and deploying it using MyEclipse 6.5 to the internal MyEclipse Tomcat server. The web service used in this tutorial will be a very simple calculator service that provides add, subtract, multiply and divide operations to the caller.

MyEclipse also supports developing web services using the existing XFire framework from previous MyEclipse releases. For folks needing to develop and deploy WebSphere JAX-RPC or WebSphere JAX-WS web services, please take a look at our MyEclipse Blue Edition of the MyEclipse IDE.

Additional resources covering web service creation using JAX-RPC, JAX-WS or XFire are included in the Resources section of this document.

2. System Requirements
This tutorial was created with MyEclipse 6.5. If you are using another version of MyEclipse (possibly newer), most of these screens and instructions should still be very similar.

If you are using a newer version of MyEclipse and notice portions of this tutorial looking different than the screens you are seeing, please let us know and we will make sure to resolve any inconsistencies.

3.新徏一个工�E?
开始我们新��Z��个Web Service Project工程File->New->Web Service Project(Optional Maven Support)

Note:A JAX-WS web service can also be generated in any existing Java EE 5 web project.

我们�l�这个工�E�取名�ؓWebServiceProject.注意JAX-WS支持只在javaEE5或更高版本的工程中是可行的。如果你需要��用低版本的工�E�类�?java1.4或�?.3)�Q�那么只能��用XFire Web Service代替JAX-WS�?

�q�里我们使用上面的JAX—WS�?
4.创徏服务�c?
服务�c�d��是一个普通的java�c�，负责提供我们惌��发布的执行方法。这里我们写一个简单的计算器类�Q�实现几个典型的计算器应用方法，如加减乘除�?
首先我们先徏一个包�Q�WebServiceProject->src->new->package,取名com.myeclipseide.ws

让后我们在这个包下徏一个类,Calculator.java.

�Ҏ��上面提到的，�q�个计算器类实现计算器的加减乘除��法�Q�简单实玎ͼ�
Java代码

package com.myeclipseide.ws;

public class Calculator {
public int add(int a, int b) {
return (a + b);
}

public int subtract(int a, int b) {
return (a - b);
}

public int multiply(int a, int b) {
return (a * b);
}

public int divide(int a, int b) {
return (a / b);
}
}

可以看出�Q�这个类中的�Ҏ��是非常简单的�Q�没有用到特�D�的注释�q�有接口�Q�父�c�M��cȝ��东西�?
5.创徏一个Web Service
在上面的工具条中点击新徏Web Service

Note�Q�如果没有的话可以File->New->others->Myeclipse->WebService->webService
点击之后出现的屏�q�，在Strategy中选择Bottom-up scenario�Q�因为我们已�l�徏立好了Calculator�c�而且��x��据它建立JAX-WS服务�?br />

下面是创建的最后一个屏�q�，你需要选择提供webService�Ҏ��的javaBean�Q�在我们�q�个例子中就是我们已�l�徏立好的Calculator�c�R�?br />

填好之后�Q�Myeclipse会自动帮我们填满其他的项�Q�Select Generate WSDL in project and hit Finish.

点击完成之后�Q�Myeclipse会自动生成CalculatorDelegate代理�c�，�q�有一些必��ȝ��JAX-WS描述�W�，而且会自动在服务器目录下的web.xml中配�|�WebService的一些mappings�Q�方便将webService部��v到服务器中�?

到此web service已经建立好了�Q�我们开始部�|�它然后�q�行��试�?
6.部��v和测试webService�?
�q�里我们不��用用Myeclipse自带的tomcat服务器，使用自己应经在电脑中部��v好的tomcat5.5�?
在server面板中右击，选择configure

部��v自己的tomcat注意选择jdk要跟��目中的相同�?

现在要向工程中导入JAX-WS的jar�?
在项目名�U�C��叛_��->properties->Add Library->Myeclipse Libraries->最后面的两个�?

点击完成�Q�导入成功�?
Note�Q�Myeclipse自带的tomcat中有自带的这两个jar包，可以不用导入�?

6.1部��v
在部�|�好的tomcat服务器上叛_��选择Add Deployment

点击完成�?
6.2��试
�q�行tomcat服务器，在工��h��中点击launch WebService Explorer

打开后，点击右上角的WSDL视图�Q�可以看��C��面的屏幕

在WSDL URL中填写�\径：http://localhost:8888/WebServiceProject/CalculatorPort?WSDL
解释下�\径组成：
http://localhost:8888/是服务器的�\径，我的端口��h��8888�Q�可以根据自��q��更改�Q�一般都�?080�?
/WebServiceProject = We know by default the Web Context-root that is used to deploy(部��v) web projects matches the name of the projects. (因�ؓ我们没有��个工�E�自定义我们的Web Context-root�Q�所以他��是�q�个工程的名�?
/CalculatorPort = As we saw from the last screenshot in Section #5, when our JAX-WS web service was generated, it was bound using a servlet-mapping in the web.xml file to the /CalculatorPort path.
XML代码

<servlet>
    <description>JAX-WS endpoint - CalculatorServicedescription>
    <display-name>CalculatorServicedisplay-name>
    <servlet-name>CalculatorServiceservlet-name>
    <servlet-class>
        com.sun.xml.ws.transport.http.servlet.WSServlet
    servlet-class>
    <load-on-startup>1load-on-startup>
  servlet>
  <servlet-mapping>
    <servlet-name>CalculatorServiceservlet-name>
    <url-pattern>/CalculatorPorturl-pattern>
  servlet-mapping>
<servlet>
    <description>JAX-WS endpoint - CalculatorServicedescription>
    <display-name>CalculatorServicedisplay-name>
    <servlet-name>CalculatorServiceservlet-name>
    <servlet-class>
        com.sun.xml.ws.transport.http.servlet.WSServlet
    servlet-class>
    <load-on-startup>1load-on-startup>
  servlet>
  <servlet-mapping>
    <servlet-name>CalculatorServiceservlet-name>
    <url-pattern>/CalculatorPorturl-pattern>
  servlet-mapping>

WSDL = This is a universal query string argument that can be added to the end of any web service which will tell the web service to return it's full WSDL to the caller. In this case, the WSDL is returned to our Web Services Explorer tool which loads it up, and displays the web services exposed operations to us.
弄清楚之后，我们开始测试，比如我们选择add�Ҏ��Q?
填写args�Q�点击go�Q�在status中就会显�C�结果�?nbsp;

�l�果是正��的�?
7.创徏Webservice Client
现在我们已经部��v好Webservice�Q�而且应经��试�q�了�Q�那我们新徏一个Webservice client�Q�来调用Webservice提供的方法�?
7.1新徏一个java project�Q�给他取个名字。比如我们叫它ClientofWebService

在工��h��中点击new Web Service Client

然后按照以下步骤操作�Q?

The last step of the web service client creation is to specify either a WSDL File or a WSDL URL for the wizard to retrieve the web service WSDL from. In our case we are using the URL and generate the client into the new package com.myeclipseide.ws.client:

http://localhost:8888/WebServiceProject/CalculatorPort?WSDL

点击Next知道完成�?
可以看到在新建的java project ClientofWebService中，src文�g夹下产生了许多的文�g�Q�根据名�U�我们大体可以了解其意思，可以打开看一下源代码�Q�其实不隄��解。比如add文�g�Q�就是Calculator�c�M��add�Ҏ��的两个参数的get和set�Ҏ��。其他类伹{�?
我们在文件夹下见一个类test.java写一个main函数��试
Java代码

public static void main(String[] args) {
    /* Create the service instance */
    CalculatorService service = new CalculatorService();
    CalculatorDelegate delegate = service.getCalculatorPort();

    /* Using the web service, perform the 4 calculations */
    System.out.println( "1. 3+7=" + delegate.add(3, 7));
    System.out.println( "2. 12-2=" + delegate.subtract(12, 2));
    System.out.println( "3. 9*9=" + delegate.multiply(9, 9));
    System.out.println( "4. 40/2=" + delegate.divide(40, 2));
}

�q�行得到如下�l�果�Q?
1. 3+7=10
2. 12-2=10
3. 9*9=81
4. 40/2=20
��试完成�?
