利用axis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
