To learn web service, we need to learn WSDL. This xml file defines the services that we deploy in our web service.
Here, we get a example of WSDL.

<?xml version="1.0" encoding="UTF-8"?>

<wsdl:definitions targetNamespace="http://localhost:8080/bookstore/services/BookSvc"

xmlns="http://schemas.xmlsoap.org/wsdl/"

xmlns:apachesoap="http://xml.apache.org/xml-soap"

xmlns:impl="http://localhost:8080/bookstore/services/BookSvc"

xmlns:intf="http://localhost:8080/bookstore/services/BookSvc"

xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/"

xmlns:tns1="http://model.bookstore.com"

xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/"

xmlns:wsdlsoap="http://schemas.xmlsoap.org/wsdl/soap/"

xmlns:xsd="http://www.w3.org/2001/XMLSchema">

<wsdl:types>

</sequence>

</complexType>

</Schema>

</wsdl:types>

<wsdl:message name="addBookResponse">

</wsdl:message>

<wsdl:message name="addBookRequest">

<wsdl:part name="book" type="tns1:Book"/>

</wsdl:message>

<wsdl:portType name="BookSvc">

<wsdl:operation name="addBook" parameterOrder="book">

<wsdl:input message="intf:addBookRequest" name="addBookRequest"/>

<wsdl:output message="intf:addBookResponse" name="addBookResponse"/>

</wsdl:operation>

</wsdl:portType>

<wsdl:binding name="BookSvcSoapBinding" type="intf:BookSvc">

<wsdlsoap:binding style="rpc" transport="http://schemas.xmlsoap.org/soap/http"/>

<wsdl:operation name="addBook">

<wsdlsoap:operation soapAction=""/>

<wsdl:input name="addBookRequest">

<wsdlsoap:body encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" namespace="http://bookstore.com" use="encoded"/>

</wsdl:input>

<wsdl:output name="addBookResponse">

<wsdlsoap:body encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" namespace="http://localhost:8080/bookstore/services/BookSvc" use="encoded"/>

</wsdl:output>

</wsdl:operation>

</wsdl:binding>

<wsdl:service name="BookSvcService">

<wsdl:port binding="intf:BookSvcSoapBinding" name="BookSvc">

<wsdlsoap:address location="http://localhost:8080/bookstore/services/BookSvc"/>

</wsdl:port>

</wsdl:service>

</wsdl:definitions>

So many infomations in this file. But first of all, we need to understand the format of this file.
To me, the defination of namespace is a problem.

My qustions are: For xmlns, xmlns:tns1,xmlns:intf..., What do they mean? How to use them?

After I refered to some articles in internet. I get the answer:
每個namespace屬性都聲明了一個縮略語，用在文檔中。例如"xmlns:xsd"就為
But I get another question that no one reply.
refer

'我們都知道，WSDL應(yīng)該是格式正確的XML文檔。進(jìn)一步，還應(yīng)該把它看作一個Schema，因此，<definitions>元素中可以定義targetNamespace屬性，表示在這個元素下的所有元素都屬于這個目標(biāo)名稱空間。

xmlns表示缺省的名稱空間，...'

So what's difference between 'targetnamespace' and default 'xmlns'?
?????????????????????????????????????????????????????????
