Learning Objectives<br />
* To understand the place of SOAP in Web services<br />
* To appreciate the advantages of using SOAP<br />
* To understand the basic SOAP structure<br />
* To explore SOAP requests and responses on a Web service<br />
=SOAP Protocol Messaging=<br />
[[File:SOAP 1.png|600px]]<br />
<br />
=SOAP Metaphor ⌘=<br />
*XML = Language of message<br />
-English<br />
<br />
*SOAP = Style of message<br />
-Business letter <br />
<br />

=SOAP Definition ⌘=<br />
“a lightweight protocol for exchange of information in a decentralized, distributed environment”<br />
(W3C)<br />
=SOAP ⌘=<br />
* Originally: “Simple Object Access Protocol”<br />
* Just “SOAP” since 1.2<br />
* Protocol used for exchanging data<br />
* Uses XML to describe information<br />
* Usually uses HTTP(S) for transportation<br />
=Advantages of SOAP ⌘=<br />
* XML<br />
* HTTP<br />
* Additional Benefits<br />
=XML Benefits ⌘=<br />
*Interoperability<br />
-Platform-neutral<br />
<br />
-Language-neutral<br />
<br />
-Vendor-neutral<br />
*Easy to implement <br />
-Minimum Web server + ASP page/CGI script<br />
=HTTP Benefits ⌘=<br />
* HTTP well known and used network protocol<br />
* Firewall-safe<br />
* Can use HTTP over SSL (HTTPS)<br />
* NB: SOAP can use other transport protocols<br />
=Additional Benefits ⌘=<br />
*Robust <br />
-Can create own XML structure<br />
<br />
*Use other XML technologies<br />
-E.g. XML-Signature for security<br />
<br />
*Can use attachments<br />
*Flexible<br />
-Can represent complex messages<br />
<br />
Can cope with messages being passed along a chain<br />
=SOAP Structure ⌘=<br />
*Envelope<br />
-Container for message <br />
*Header<br />
-Information about the message<br />
*Body<br />
-The message<br />
=A SOAP Service Request ⌘=<br />
[[File:SOAP 4.png|600px]]<br />
<br />
=<Envelope> ⌘=<br />
<mySoap:Envelope <br />
xmlns:mySoap="http://schemas.xmlsoap.o<br />
rg/soap/envelope/" <br />
xmlns:wsx="http://www.webserviceX.NET"><br />
<br />
* Root element for XML doc<br />
* Lists namespace declarations, e.g:<br />
-mySoap = SOAP XML namespace<br />
<br />
-wsx = namespace for service provider<br />
=<Header> ⌘=<br />
<mySoap:Header/><br />
(<mySoap:Header></mySoap:Header>)<br />
<br />
* Optional<br />
* Often omitted<br />
* Could contain instructions for handling message<br />
-e.g. user credentials<br />
=<Body> ⌘=<br />

<br />
=A SOAP Service Response ⌘=<br />
[[File:SOAP 6.png]]<br />
<br />
=A SOAP Service Response - Fault ⌘=<br />
[[File:SOAP 3.png]]<br />
<br />
=<Fault> ⌘=<br />
[[File:SOAP 7.png]]<br />
<br />
=Summary Exercise ⌘=<br />
Using the JMeter test tool, send a request to the Periodic Table Web service<br />
<br />
* Use Get Atomic Number to get the atomic number of Hydrogen<br />
* Analyse the Service Response and identify SOAP structural elements: namespaces, root element, header, body, fault<br />
* Investigate other methods/Web services available</div>Łukasz Sokołowski
