首先下載soap，把soap.war放到tomcat/webapp/目錄下，在classpath下面加入soap.jar、mail.jar和 activation.jar，然后創建一個Service和Client，把Service.class放到 tomcat/webapp/soap/WEB-INF/classes目錄下，然后把mail.jar和activation.jar放到 tomcat/webapp/soap/WEB-INF/lib下面，并寫一個配置文件用于部署服務。
<isd:service
?? xmlns:isd="http://xml.apache.org/xml-soap/deployment"
?? id="urn:service" checkMustUnderstands="true">
????? <isd:provider type="java" scope="Request" methods="setAlarm">
????? <isd:java class="work.Service" static="false"/>
?? </isd:provider>
</isd:service>
上面的work.Service是類的全名，setAlarm是提供的服務名,urn:service是URI。再寫一個腳本來調用配置文件部署服務
java org.apache.soap.server.ServiceManagerClient
http://localhost:8080/soap/servlet/rpcrouter deploy deploy.xml
啟動Tomcat之后，啟動腳本，然后執行Client代碼就可以了，Client的主體代碼很簡單，代碼里面就不加入注釋了。
