在现有应用中加入WebService

在现有应用中加入WebService

第一步:添加必须的类库

列表于下:

activation.jar
axis-ant.jar
axis.jar
commons-discovery.jar
commons-logging.jar
jaxrpc.jar
log4j-1.2.8.jar
mail.jar（可选)
saaj.jar
wsdl4j.jar
xmlsec.jar（可选)

第二步:修改web.xml

1.添加servlet定义

 <servlet>
    <servlet-name>AxisServlet</servlet-name>
    <display-name>Apache-Axis Servlet</display-name>
    <servlet-class>
        org.apache.axis.transport.http.AxisServlet
    </servlet-class>
  </servlet>

  <servlet>
    <servlet-name>AdminServlet</servlet-name>
    <display-name>Axis Admin Servlet</display-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>
    <display-name>SOAPMonitorService</display-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>

2.添加servlet映射

  <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>
 -->

3.添加MIME类型

  <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>

第三步:编写WebService程序

例：在应用目录下添加文件Hello.jws

源代码于下：

public class Hello{
    private static int time=1;
 public String hello(String name){
  if(name==null){
   name = "";
  }
  return "你好"+name+"，欢迎来到Web服务的世界.Today is " + new java.util.Date();
    }
}
无需编译，http://localhost/ws/Hello.jws?wsdl即该webservice地址，访问即可执行。
