XML中的命名�I�间学习

Fri, 14 Mar 2008 02:11:00 GMT

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>
    <schema targetNamespace="http://model.bookstore.com" xmlns="http://www.w3.org/2001/XMLSchema">
      <import namespace="http://schemas.xmlsoap.org/soap/encoding/"/>
      <complexType name="Book">
        <sequence>
          <element name="ISDN" nillable="true" type="xsd:string"/>
          <element name="name" nillable="true" type="xsd:string"/>
          <element name="page" type="xsd:int"/>
        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:
每个namespace属性都声明了一个羃略语�Q�用在文档中。例�?xmlns:xsd"��׃ؓ
But I get another question that no one reply.
refer

'我们都知道，WSDL应该是格式正��的XML文档。进一步，�q�应该把它看作一个Schema�Q�因此，元素中可以定义targetNamespace属性，表示在这个元素下的所有元素都属于�q�个目标名称�I�间�?/p>

xmlns表示�~�省的名�U�空��_��...'

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

关于UndoManager的小故事

Wed, 17 Jan 2007 05:24:00 GMT

现在正在做的��目中，��有undo、redo的操作。��用的是java本��n的undoManager。但是因��Z��用的�W�三方��Y件包已经把它��装�q�了�Q�所以用��h��q�不是直接��用java的undomanager。其��_��遇到�q�样的问题：有些操作不想被undo所��理�Q�但是图形上的变换却��L��会被listener加入到undo的edits中。想了很多办法，包括�l�承再封装undomanager��edits传出来保存，需要恢复的时候再设进厅R��discard所有的edits、找�ȝ��三方软�g��装undoableEdit的方法，以��得操作不被undo....最后，用最��单的�Ҏ��解决问题�Q�设�|�一个boolean变量,然后重蝲listener的方法，用这个变量来控制是否调用super.undoableEditHappened卛_��?唉，真笨啊，用这么简单的问题都能解决的，搞了老半�?.. ---------------------------- A ja A ja, fighting fighting
