All leading e-business platforms will support at least basic Web services infrastructure by 2002
?
By 2003, more than 75% of Web services in production will be supported by Web services
infrastructure provided by IBM, Microsoft and two to three other vendors
?
"The industry desperately wants vendors to move away from proprietary systems that lock firms into technologies. IBM has seen the writing on the wall, and is moving early. This is the way the industry is moving."

What is the press saying?
?
"Web Services - IBM Gets it “
?
IBM shows an unmistakably greater sense of openness and customer-centricity.
?
With IBM, customers can use the combination of language,
operating system and hardware that makes sense for them, not the one that furthers the platform ambitions of their supplier.
?
In general, IBM "gets it" when it comes to multivendor interoperability on the Web.
?
IBM learned the hard way that embracing open, interoperable standards is not just a good strategy?it's the only strategy.
We wonder how long it will take for Microsoft and Sun to learn
the same lesson.

Building The Web Service
?
1- Build the service as a bean
?
2- Register the service with the SOAP router
?
3- Define a service using WSDL
?
4- Register the service with UDDI
?
5- Call the service from a client using SOAP over HTTP either …
?
5.1- Directly using the basic SOAP interface ignoring the UDDI registration
?
5.2- By looking up the service in UDDI and binding to it
through WSDL
Basic Design Choices
? 1) just SOAP
?
Point-to-Point, single client technology
? 2) SOAP + WSDL definition
?
just WSDL - can configure, but not full repository lookup
? 3) SOAP + WSDL + UDDI
Step 1: Building the SOAP Connection
?
1) Define and build the service and its interfaces
?
build Java classes, C++, VB, COM component
?
2) Register the service with the SOAP router (deploy)
?
Can be entered via Webform at the Apache SOAP administrator GUI
?
Manually create a deployment descriptor and send it to the SOAP router by:
?
Invoking program from Apache to 'deploy' - i.e. a bat file
?
Develop your own program/script to perform deployment
steps automatically
Step 1: (continued)
?
3) Write a client to exercise the service:
?
At a minimum:
?
Build a Java program to make a Apache SOAP API call
?
This will:
?
create the SOAP envelope
?
send HTTP request
?
rpc router picks up the deployment descriptor for the requested services
?
creates a Java object and pass parameter into the correct method
?
which should create a response object or return a fault
WebServer - HTTP
RPC Router Client
Web Service
To define a WebService
1) Create a deployment descriptor file (or use Webform for definition)
2) Invoke Apache utility to deploy to RPC router HTTP
Deploy
WebSphere
1
Descriptor
2
3
Execute the client from a JVM - invoke SOAP APIs
3
2 1
Define the service and its interfaces
HTTP Listener
Step 1: (continued)
Now the service is known by the server hostname, port, and the Servlet "rpcrouter"
Step 2: Creating the WSDL
?
For an existing bean:
?
Use Service Wizard from WSDE to build a WSDL
?
Deploy WSDL to the Webserver:
?
So that it can be located via an URL
?
Can now use WSDL to configure client
?
Still a level of 'manual' interaction required
?
To provide access to WSDL
?
Benefit of WSDL:
?
Other technologies can read it, i.e. MS toolkit
?
(but MS toolkit cannot use the IBM/Apache WSDL today)
?
W3C standardization on WSDL (but implementation is
currently different)
Step 2: Creating the WSDL
WebServer - HTTP
RPC Router Client
Web Service
Make WSDL file external available:
I.e. URL through Webserver
HTTP
WebSphere
1 2
1
Use Wizard from WSDE to create:
• 1) WSDL file
• 2) client proxy
WSDL 2
Client can now request the WSDL data and construct invocation from provided information i.e the URL of the WSDL object
For example, http://localhost:8080/myservicesdescription.wsdl ---or use a provided proxy ! ? ? ?
Step 2: From the Client Side...
? Accessing the WebService:
?
1) Easiest way: using a proxy object (I.e. no changes for the app)
?
2) A bit more work: use the Toolkit APIs
?
3) Terrible way: code the SOAP requests directly
?
(e.g over HTTP today)
? Consequence:
?
The more you code directly into your client application,
the less flexibility you have on choosing aspects of the
service dynamically.
Service Discovery (Binding)
? 1) Dynamic - at runtime
? 2) At startup of services (deployment time)
? 3) Static ? services found and bound to at development time
?
Tools browse/search
?
? UDDI registry is a services directory
?
Contains service definitions
?
Programatically searchable
Step 3: Connecting to a UDDI Registry
GOAL: be able to obtain WSDL from UDDI
?
1) Use e.g. UDDI browser to register business (service provider) with UDDI
?
2) Register services (e.g. through UDDI4J)
?
3) from client: need to issue a ‘ FIND ’
?
Very specific:
?
Category #
?
Get WSDL file (first instance) from list
?
Queries could be:
?
‘ Give me all services of this company ’
?
Once the service description is obtained, the service can be
invoked as described in ‘ Step 2 ’
Client Side API Selection
? 2 options for Interface APIs again … .
? What Storebrand did not use … ..
?
1) SOAP level APIs using MS SOAP Toolkit V2 B1
? This beta does not support security reliably (too many bugs)
? It was also not supported for production
?
status of March 2001
Client Side API Selection
?
What Storebrand has implemented:
?
2) low level API: WININET
?
APIs from INET access (as explorer)
?
Gives for HTTPS well known interfaces
?
We needed to prove during the project the same level of security as the WEB solution with Smartcards
?
Use of client side certificate authentication
?
distribution method of certificate has not been determined yet
?
SSL
?
Consequence of using the WININET APIs:
?
need to construct SOAP envelop
?
cumbersome to get the messages right
Context Propagation
?
SOAP does not offer a standard mechanism to pass
additional information to a service beyond the parameter description
?
Need for adding data like session ids, admin or security data
?
Apache has implemented a ‘ pluggable provider ’ facility that can be used as a temporary remedy
?
Future versions of Apache SOAP will provide AXIS (Apache eXtensible Interaction System)
?
A pluggable (handler) framework for pre- and
postprocessing
To WSDL or Not?
? Storebrand did not use a WSDL - Why ?
? This is what actually got implemented:
?
Services information retrieved from a property file
?
Contains location info PLUS config parameters for COM environment, e.g. max msg size, etc.
?
No benefit of using WSDL in current scenario
Interoperability
?
No standard test suite available
?
Check discussion at:
?
http: // groups.yahoo.com/group/soapbuilders
?
who should do this ?
?
Apache / IBM vs MS
?
SOAP support fixed since Toolkit V2.2
?
WSDL 1.0 support problematic
?
SDL - NASSL heritage
?
document structure different from MS / IBM
?
can be fixed, by manual editing
?
W3C acknowledged standard submission of WSDL 1.1 on
March 6th
Reliable Message Delivery
? QoS - Quality of Service
?
Not there - at least in the specs
?
Need to be solved either
? on application level
? transport level
? Today: XML over HTTP (HTTPS)
?
Message Ids provided by application will guarantee that a message is delivered, and only delivered once
?
Data integrity guaranteed through SSL encryption

Review of Achievements
MicroDoc GmbH
?
Challenge
? Help a customer to provide information and services to third parties having a variety of IT infrastructures. Online access was essential, so they needed a technology that allowed them to create manageable B2B connections. As the customer services evolve, they must publish these offerings as quickly as
possible. To help their customers achieve a more efficient level of integration, MircoDoc looked to Web Services technologies and partnering with IBM.
?
Solution
? Provide the customer with a Web Services-based call management center, using SOAP messaging to communicate between the host site and 80 remote offices. The solution was designed to be expanded to handle new service types which will be published in a UDDI registry.
?
IBM Content
? Call management system based on WebSphere, SOAP, JSPs, and DB2.
?
Value
? The customer will be able to share new internal processes with business
partners through the use of Web Services without extra effort. Application design is simplified because a single service-architecture will be used for
HTML and XML communication to end users and business partners alike. TCIs ability to quickly respond to new market demand will significantly be improved.
