篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了MYECLIPSE 开发Web Service之详细讲解--第一节相关的知识，希望对你有一定的参考价值。

     最近由于青海的项目要求，需要提供一个外围接口给其他厂商，最后决定用WEBSERVICE的方法给外围提供接口，同时内部用EJB来实现组件封装，这就涉及到了WEB SERVICE的开发，部署，测试已经EJB的开发，部署，和测验，那么这2样技术我相信很多人喜欢吧，也很想学，是吧，那我就实例开发来讲解吧，先讲WEBSERVICE的开发，然后我会一节一节的来完善，最终让大家都知道，现在我就将我自己的一些心得写下来。

网络上的相关资料很多，但是很抱歉，我真的很少有按照他们的示范成功过的，也许是我的悟性还不够，好了，废话不讲了，直接开发了。

=一：环境

 工具： Eclipse 3.2 +MyEclipse 5.0.0.

JDK是1.4，相应的JAR包：axis.jar axis-ant.jar等，这些你必须自己准备好，呵呵

上面的应该您都会吧，不会你可以和我联系tropica@163.com

二：开始

1：先创建一个WEB工程，这个所有人都会的，不要我多讲。工程名称为：CallSmsService

2：替换相与的配置文件，这一步主要完成相关SERVELET的配置，找到WEB-INF下面的WEB.XML文件，然后加上下面的内容

 <listener>
  <listener-class>
   org.apache.axis.transport.http.AxisHTTPSessionListener
  </listener-class>
 </listener>

 <servlet>
  <servlet-name>AxisServlet</servlet-name>
  <servlet-class>
   org.apache.axis.transport.http.AxisServlet
  </servlet-class>
 </servlet>

 <servlet>
  <servlet-name>AdminServlet</servlet-name>
  <servlet-class>
   org.apache.axis.transport.http.AdminServlet
  </servlet-class>
  <load-on-startup>100</load-on-startup>
 </servlet>

 <servlet>
  <servlet-name>SOAPMonitorService</servlet-name>
  <servlet-class>
   org.apache.axis.monitor.SOAPMonitorService
  </servlet-class>
  <init-param>
   <param-name>SOAPMonitorPort</param-name>
   <param-value>5001</param-value>
  </init-param>
  <load-on-startup>100</load-on-startup>
 </servlet>

 <servlet-mapping>
  <servlet-name>AxisServlet</servlet-name>
  <url-pattern>/servlet/AxisServlet</url-pattern>
 </servlet-mapping>

 <servlet-mapping>
  <servlet-name>AxisServlet</servlet-name>
  <url-pattern>*.jws</url-pattern>
 </servlet-mapping>

 <servlet-mapping>
  <servlet-name>AxisServlet</servlet-name>
  <url-pattern>/services/*</url-pattern>
 </servlet-mapping>

 <servlet-mapping>
  <servlet-name>SOAPMonitorService</servlet-name>
  <url-pattern>/SOAPMonitor</url-pattern>
 </servlet-mapping>

 <!-- uncomment this if you want the admin servlet -->
 <!--
  <servlet-mapping>
  <servlet-name>AdminServlet</servlet-name>
  <url-pattern>/servlet/AdminServlet</url-pattern>
  </servlet-mapping>
 -->

 <session-config>
  <!-- Default to 5 minute session timeouts -->
  <session-timeout>5</session-timeout>
 </session-config>

 <!-- currently the W3C havent settled on a media type for WSDL;
  http://www.w3.org/TR/2003/WD-wsdl12-20030303/#ietf-draft
  for now we go with the basic 'it's XML' response -->
 <mime-mapping>
  <extension>wsdl</extension>
  <mime-type>text/xml</mime-type>
 </mime-mapping>


 <mime-mapping>
  <extension>xsd</extension>
  <mime-type>text/xml</mime-type>
 </mime-mapping>


 <welcome-file-list>
  <welcome-file>index.html</welcome-file>
  <welcome-file>index.htm</welcome-file>
  <welcome-file>index.jsp</welcome-file>
  <welcome-file>default.html</welcome-file>
  <welcome-file>default.htm</welcome-file>
  <welcome-file>default.jsp</welcome-file>
 </welcome-file-list>

3：上面的完成后，请您发布WEB应用，测验刚才的SERVELET是不是已经发布成功，访问地址：

http://localhost:7001/CallSmsService/servlet/AxisServlet  如果正确的话，会出现下面的内容：

And now... Some Services

如果没有出现上面的，那请你自己仔细检查原因，不知道原因的，哈哈，按照我的经验，错误应该是你发布的时候错了，没有搞清楚上下文，那你得继续好好学习WEB了。。

4：上面的OK了，好了，开始我们的核心的东东了，编辑deploy.wsdd,定义接口,将deploy.wsdd拷贝到工程应用的lib目录下，注意lib就是库文件，一般位于WebRoot/WEB-INF/lib下面，deploy.wsdd的内容为：

<!-- Use this file to deploy some handlers/chains and services      -->
<!-- Two ways to do this:                                           -->
<!--   java org.apache.axis.client.AdminClient deploy.wsdd          -->
<!--      after the axis server is running                          -->
<!--   author  xuzr@                                                         -->
<!--   java org.apache.axis.utils.Admin client|server deploy.wsdd   -->
<!--      from the same directory that the Axis engine runs         -->

<deployment
    xmlns="http://xml.apache.org/axis/wsdd/"
    xmlns:java="http://xml.apache.org/axis/wsdd/providers/java">

  <!-- Services from HelloImplService WSDL service -->
 
  <service name="CallSoapImpl" provider="java:RPC" style="rpc" use="encoded">
      <parameter name="wsdlTargetNamespace" value="http://localhost:7001/CallSmsService/services/CallSoapImpl"/>
      <parameter name="wsdlServiceElement" value="CallSoap"/>
      <parameter name="wsdlServicePort" value="CallSoapImpl"/>
      <parameter name="className" value="com.linkage.soap.CallSoapImpl"/>
      <parameter name="wsdlPortType" value="CallSoapImpl"/>
      <parameter name="typeMappingVersion" value="1.2"/>
      <parameter name="allowedMethods" value="*"/>
      <beanMapping languageSpecificType="java:com.linkage.soap" qname="ns1:CallSoapImpl" xmlns:ns1="urn:BeanService"/>
  </service>
</deployment>

里面的相关东西我解释下，CallSoapImpl是你的逻辑实现类，CallSoap是接口，如果你不明白，没有关系，下面我会讲相关的类，你就会明白了。上面的配置好了，就把这个文件放到LIB下面吧

5：发布接口，发布前要设计环境变量哦，我这里的为：

set classpath=E:/beaapp/mydomain/applications/CallSmsService/WEB-INF/lib/axis.jar;E:/beaapp/mydomain/applications/CallSmsService/WEB-INF/lib/commons-discovery-0.2.jar;E:/beaapp/mydomain/applications/CallSmsService/WEB-INF/lib/commons-logging.jar;E:/beaapp/mydomain/applications/CallSmsService/WEB-INF/lib/jaxrpc.jar;E:/beaapp/mydomain/applications/CallSmsService/WEB-INF/lib/saaj.jar;E:/beaapp/mydomain/applications/CallSmsService/WEB-INF/lib/wsdl4j-1.5.1.jar;E:/beaapp/mydomain/applications/CallSmsService/WEB-INF/lib/j2ee.jar;$classpath
细心的你就会发现，我这里的就是开始准备里的包，有的包你没有，自己去DOWNLOAD吧，网络这么发达，你表说你不知道怎么下。然后执行命令：java org.apache.axis.client.AdminClient -lhttp://localhost:7001/CallSmsService/services/AdminService deploy.wsdd  注意哦，这一补重要呢，发布成功的话，会出现这样的提示信息：

Processing file deploy.wsdd
<Admin>Done processing</Admin>

6：继续访问：http://localhost:7001/CallSmsService/servlet/AxisServlet  会多出一个节点，为：

And now... Some Services

这个就是发表成功的哦，点下CallSoapImpl这个节点，会发现有这样的提示：

CallSoapImpl

Hi there, this is an AXIS service!

Perhaps there will be a form for invoking the service here...

同时会出现最关键的东西，就是我们提供给外围的，见下面：

<?xml version="1.0" encoding="UTF-8" ?>

- < wsdl:definitions targetNamespace =" http://localhost:7001/CallSmsService/services/CallSoapImpl " xmlns:apachesoap =" http://xml.apache.org/xml-soap " xmlns:impl =" http://localhost:7001/CallSmsService/services/CallSoapImpl " xmlns:intf =" http://localhost:7001/CallSmsService/services/CallSoapImpl " xmlns:soapenc =" http://schemas.xmlsoap.org/soap/encoding/ " xmlns:wsdl =" http://schemas.xmlsoap.org/wsdl/ " xmlns:wsdlsoap =" http://schemas.xmlsoap.org/wsdl/soap/ " xmlns:xsd =" http://www.w3.org/2001/XMLSchema ">
- <!--

- < wsdl:port binding =" impl:CallSoapImplSoapBinding " name =" CallSoapImpl ">
  < wsdlsoap:address location =" http://localhost:7001/CallSmsService/services/CallSoapImpl " />
  </ wsdl:port >
  </ wsdl:service >
  </ wsdl:definitions >

如果出现上面的内容，那么就恭喜你，发布成功了，到这里为止，你只是发布成功了，可以给外围使用的，但是你要 测验自己的是不是正确，怎么办呢，OK，下一节我继续讲。
