前面两种SOAP绑定是指采用SOAP规范来形成HTTPRequest，SOAP:binding是采用SOAP1.1版本。soap12:binding是采用SOAP1.2版本。

<soap:binding

<soap12:binding

<http:binding 是采用HTTP规范来填写消息内容，调用方式如下

交互的 Web 接口：

<html>
<head>
<title>HTTP POST vs. WSDL SOAP Web Services
</title>
</head>
<body>

<br>
<center>
<h2><P>Semantic Web Service invoked
via HTTP/POST by JSP/Java Servlet</h2></P>
<FORM action=
"http://157.182.136.51:8080/HttpApp/servlet/SendHTTPRequest" method="post">
<P><b><font color="blue">Simple Server URL:
</font>

<P><b><font color="blue">GIS Server URL:

<P><b>(--The GIS Server will create a new buffer feature for any

<br>
<div><TEXTAREA NAME="request" COLS=60 ROWS=25></TEXTAREA>
<TEXTAREA NAME="response" COLS=60 ROWS=25></TEXTAREA></div>

<br>
<b>Request</b>
<INPUT TYPE=SUBMIT VALUE="Submit Request">

</FORM>
