Web services @ work
Agenda
– Everything about web services– SOAP– WSDL– UDDI– Questions– Case Study
What are Web Services ?
• Services offered over the network.
Stock Quote Service Inventory Information
Weather Service
Who should create web services?
– Existing Computing Services– Existing Data storage Services– Existing Search Services– Existing Informational Services– And…..– Everybody who want to leverage existing
functionality and offer the same to whole world.
Typical web services architecture

Clients
SMTP Server
Application Server (Axis)

Service Wrapper New Service Implementation
Enabling existing services
HTTP Server (Apache, Tomcat, IIS)
Who consumes web services ?
– Integrators– Support utilities– CRM Software
How to create web service
• Be Guided by following standards• XML• SOAP• UDDI• HTTP (or any standard protocol)
You can turn any existing functionality into web service, by adhering to above standards
Web services related Standards
– SOAP 1.2– UDDI 1.3– WSDL 1.2– HTTP 1.1
• These are set by standards body like W3C,OASIS.
Major development platforms
– Microsoft’s .NET – Sun’s Web Services API– IBM’s Websphere
When not to use web services
– Performance requirements– Security and reliability– No reuse requirements– Lack of Web services support– Organizational or technical alignment
Simple Object Access Protocol1.2
Goal
• Access objects and services on remote servers in platform independent manner

What is SOAP
– Simple Object Access Protocol– Lightweight protocol for exchanging structural
information– Uses XML Technologies– Independent of any platform/technology– Simple and Extensible
What is NOT SOAP
• A full-fledged distributed object system with support for
• Objects-by-reference• Activation• Message batching• Distributed garbage collection• Naming and directory services
• SOAP sacrifices these features for platform-neutrality and extensibility
Typical SOAP message• <soap:Envelope
xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" >• <soap:Header>• <!-- header element(s) here -->• </soap:Header>• <soap:Body>• <!-- body element(s) here -->• </soap:Body>• </soap:Envelope>
Example SOAP Message• <?xml version="1.0" encoding="UTF-8"?>• <SOAP-ENV:Envelope
xmlns:xsd="http://www.w3.org/2001/XMLSchema"•
xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"• xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">• <SOAP-ENV:Body>• <ns1:echoString xmlns:ns1="http://soapinterop.org/">• <testParam xsi:type="xsd:string">Hello!</testParam>• </ns1:echoString>• </SOAP-ENV:Body>• </SOAP-ENV:Envelope>

</order></ns1:customerOrder></soapenv:Body></soapenv:Envelope>
Processing SOAP Message
– SOAP HEADER Block and Node• Supports Multiple Message Exchange Patterns
– One Way– Request/Response– Peer to Peer
• Each Message is independently Processed• Roles for Node
– next– none– ultimatereceiver
•
What happens when message arrives
1.Node determines set of roles in which it needs to act on message
2.Identify all the header blocks targeted for the Node
3.If header block is not understood, generate fault and no further processing is done.
4.Process mandatory SOAP HEADER block
5.Process BODY if Node is ultimate receiver
6.Relay message if Node is playing intermediary role.
SOAP Extensibility
– SOAP Processing Model– SOAP Binding Framework
• Formal set of rules for carrying soap message over underlying protocol.
• HTTP Binding
SOAP EncodingStyle– http://www.w3.org/2001/12/soap-encoding– To define data types used in the document
<?xml version="1.0"?><soap:Envelopexmlns:soap="http://www.w3.org/2001/12/soap-envelope"soap:encodingStyle="http://www.w3.org/2001/12/soap-encoding">...Message information goes here...</soap:Envelope>
SOAP RPC Representation
– Method Invocation modeled as single struct– Struct is name identical to method– Parameter has the same name and order– Method Response is also modeled as struct
Data Types
• Supported• String• int/Integer• decimal• float/Float• double/Double• date• boolean/Boolean• Long/Long• Short/Short• Byte/Byte• hex
• Not Supported• BigDecimal• Other ?
Where can FAULT Occur
• Client
• Server
• Protocol
Example FAULT Message in HTTP
• HTTP/1.1 500 Internal Server Error• Content-Type: text/xml; charset="utf-8"• Content-Length: nnnn
• <SOAP-ENV:Envelope• xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">• <SOAP-ENV:Body>• <SOAP-ENV:Fault>• <faultcode>SOAP-ENV:Server</faultcode>• <faultstring>Server Error</faultstring>• <detail>• <e:myfaultdetails xmlns:e="Some-URI">• <message>• My application didn't work• </message>• <errorcode>• 1001• </errorcode>• </e:myfaultdetails>• </detail>• </SOAP-ENV:Fault>• </SOAP-ENV:Body>• </SOAP-ENV:Envelope>

SOAP-less web service?
Apache SOAP Architecture
SOAP : Performance
SOAP - Namespaces
SOAP-interoperability
• Following things must happen• The ability for the server to parse the client's SOAP
envelope. • The ability for the server to deserialize the encoded
parameter contained within the envelope • The ability for the client to parse the SOAP envelope
sent by the server in response • The ability for the client to deserialize the encoded
parameter sent back from the server.
• Main concerns• SOAP Specification follow up• Data type• Precision support for float/decimal, date time, Arrays
Food for thought
– Scenario where soap intermediary is needed– How much payload of minimal SOAP Packet.– Do you really need SOAP for web services?– SOAP Over JMS?– SOAP and Performance?– SOAP slower than XML-RPC by almost 8
times !!

Agenda
– What is WSDL– Why WSDL– WSDL Structure– Usage– Consumers of WSDL– Questions
Your business for others…
– You need grammar to describe what your business do. Grammar should address ..
• What services are offered by you• How can others invoke a service• What information your service needs• How user will provide information• What information you can provide• What format you expect
WSDL is the answer

UDDI ConceptsBasics: UDDI– Global registry hosted by UDDI Operators
– UDDI Operators (IBM, Microsoft)– Defined process for managing information– Business publish their information for free– “Registered once, Published everywhere principle”– Information is replicated = Service Cloud
Business Benefits• UDDI project is not industry-specific, hence any
industry offering services can benefit.• Quickly discover the right business from millions
currently online• Reaching new customers • Expanding offerings • Extending market reach • Describing their services and business
processes programmatically in a single, open, and secure environment

tModel
• Acronym for technical Model
• tModel provide the ability to describe compliance with a specification, a concept, or a shared design.
What is tModel
• tModel represents context (namespace)

• <categoryBag>• <keyedReference tModelKey="BusinessTypeClassification"• keyName=“Sport" keyValue=“34343">• <keyedReference tModelKey=“RegionClasification" • keyName=“country" keyValue=“CHN">• </categoryBag>
Example
• Location• Industry• TimeZone
With categorization it is possible to convey that
I am a sports company operating in China, India and USA
bindingTemplate
– Provide Technical description of a web service
– Describes an instance of web service offered at a particular network address.
– Contains following data» description» accessPoint» categoryBag» tModelInstanceDetails
UDDI - Categorization
– Being able to distinguish and differentiate data is as important as being able to find data.
– Adorn UDDI Entities with property bags– Multiple classification system– Powerful search qualifiers– Metadata attributed using keyedReference

Food For thought
• When UDDI really needed
• Do all services registered with UDDI need to be SOAP Services
• Why tModel is called that way?
• Can tModel be categorized as well?
• Try registering your business in IBM Business Registry ( http://uddi.ibm.com)
