使用 Apache CXF 調用全球氣象 GlobalWeather 提供的 WebService

範例來源: http://www.webservicex.net/globalweather.asmx

Tags: jaxws, cxf, apache, webservice, myeclipse, maven, hello world, java, eclipse, byron, wsdl2java, wsdl first, jetty, tomcat, jaxb, marshal, unmarshal, dom4j, jaxen, global, weather, 氣象

提及技巧:

* WDSL 內定目錄

* 用 DOM4J 取得温度節點

* 用 Spring 取得 proxy bean

* pom.xml
