导读：Webservice地址为? http://192.168.13.232:8989/ws_01/umgsai JSP页面地址为?http://192.168.13.232:8080/Demo/index.jsp Webservice的请求体如下 soapenv:Envelope?xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"?xmlns:q0="http://ws.umgsai.

Webservice地址为?http://192.168.13.232:8989/ws_01/umgsai

JSP页面地址为?http://192.168.13.232:8080/Demo/index.jsp

Webservice的请求体如下

<soapenv:Envelope?xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"?xmlns:q0="http://ws.umgsai.com/"?xmlns:xsd="http://www.w3.org/2001/XMLSchema"?xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
??<soapenv:Body>
????<q0:sayHello>
??????<arg0>sa</arg0>
????</q0:sayHello>
??</soapenv:Body>
</soapenv:Envelope>

Webservice的响应体如下

<S:Envelope?xmlns:S="http://schemas.xmlsoap.org/soap/envelope/">
??<S:Body>
????<ns2:sayHelloResponse?xmlns:ns2="http://ws.umgsai.com/">
??????<return>Hello?sa</return>
????</ns2:sayHelloResponse>
??</S:Body>
</S:Envelope>

JSP页面如下

<%@?page?language="java"?contentType="text/html;?charset=UTF-8"
	pageEncoding="UTF-8"%>
<!DOCTYPE?html?PUBLIC?"-//W3C//DTD?HTML?4.01?Transitional//EN"?"http://www.w3.org/TR/html4/loose.dtd">

	<button?onClick="reqWebservice()">Ajax请求Webservice</button>
	<button?id="WebserviceJQuery">Ajax请求Webservice?with?JQuery</button>
</body>
</html>

存在跨域访问的问题，只能通过?http://192.168.13.232:8080/Demo/index.jsp?来访问。

通过?http://localhost:8080/Demo/index.jsp来访问是提示错误。
