web service 初识 axis (一)

1.依赖类库

环境变量：

    set AXIS_HOME=c:/axis
    set AXIS_LIB=%AXIS_HOME%/lib
    set AXISCLASSPATH=%AXIS_LIB%/axis.jar;%AXIS_LIB%/commons-discovery.jar;
          %AXIS_LIB%/commons-logging.jar;%AXIS_LIB%/jaxrpc.jar;%AXIS_LIB%/saaj.jar;
          %AXIS_LIB%/log4j-1.2.8.jar;%AXIS_LIB%/xml-apis.jar;%AXIS_LIB%/xercesImpl.jar

 

axis的lib目录下所有的jar文件

activation-1.1.jar和mail-1.4.jar，没有这两个文件，在运行的时候会有警告信息，不过程序可以正常运行。我是在xfire中找到的这两个文件。

xmlsec-1.3.0.jar这是一个可选包，没有也不会出现警告信息。从这个可以找到它 http://xml.apache.org/security/。

2.配置服务器端

%tomcat_home%|-webapps  |-axis    |-WEB-INF      |-web.xml      |-lib        |-*.jar

按照结构放置好目录和文件后，修改web.xml的内容。

<?xml version="1.0" encoding="GBK"?><!DOCTYPE web-app PUBLIC     "-//Sun Microsystems, Inc.//DTD Web    Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd"><web-app>    <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>101</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>102</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 id="WelcomeFileList">    <welcome-file>index.jsp</welcome-file>    <welcome-file>index.html</welcome-file>    <welcome-file>index.jws</welcome-file>  </welcome-file-list></web-app>

3.发布jws

HelloWorld.jws

public class HelloWorld {    public String sayHello() {        return "hello world!";    }}

把HelloWorld.jws复制到tomcat的webapps/axis下，然后将其改名为HelloWorld.jws。

在浏览器访问http://localhost:8080/axis/HelloWorld.jws，可以看到提示发布成功的信息。

编写客户端

package anni;import org.apache.axis.client.Call;import org.apache.axis.client.Service;import javax.xml.namespace.QName;public class TestClient {   public static void main(String [] args) {       try {           String endpoint = "http://localhost:8080/axis/HelloWorld.jws";           Service service = new Service();           Call    call    = (Call) service.createCall();           call.setTargetEndpointAddress(new java.net.URL(endpoint));                      call.setOperationName(new QName("sayHello"));           String ret = (String) call.invoke(new Object[]{});           System.out.println(" got '" + ret + "'");       } catch (Exception e) {           System.err.println(e.toString());       }   }}

 

注意：使用jws只能发布没有使用package打包的类,有一定的局限性，但是比较简单，适合入门。
