- 6. What is SOA?
Service Oriented Architecture
Term originated from IBM Web Services work in 2000?
Million and one attempts to produce a ‘catchy’ paragraph
– Strategy (both IT and Business)
– Services
– Interoperable
– Standards
Aims to address perceived limitations in previous application
integration techniques.

- 7. SOA Evolution
Service Oriented Architecture – ‘Plateau of Productivity’
Not just about enabling a legacy application to be called as a web
service.
High level business process design
SOA Maturity Model
Availability of tools
– Server : Oracle SOA Suite (+ others, I guess!)
– Designer : Oracle JDeveloper (ditto)
SCA – Service Component Architecture (OASIS Standard)

- 8. What are Web Services?
Not just an API!
Salient points
– Platform independent (XML everywhere…)
– Transport independent (i.e. not tied to a specific protocol)
– Loosely coupled
– Contract
– Standards (next slide!)
8 Copyright © 2012, Oracle and/or its affiliates. All rights reserved.
- 9. What are Web Services?
Gradual emergence of standards
– XML & XSD
– SOAP
– WSDL
[Side note: even W3C gets confused between Web Service Definition
Language and Web Services Description Language!]
– Java Platform
JAX-RPC
JAX-WS (initially called JAX-RPC 2.0)

- 13. Security Before ‘Web Services Security’
Applies to OTM versions from v5.0 to v6.2
Credentials were passed according to transport protocol
– For example, SOAP over HTTP used Basic Authentication HTTP Header
Encryption required SOAP over HTTPS
Commonly include credentials in the message itself.
– OTM accepted Transmission Header with username/password or
username and IP authentication.

- 14. Web Services Security – WS-Security
WSS: SOAP Message Security v1.1
OASIS Specification of an XML syntax for security related data in the
SOAP Header
Supports different ‘profiles’
– Username Token Profile
– SAML Token Profile
– X.509 Token Profile
– Kerberos Token Profile
– Rights Expression Language (REL) Token Profile
14 Copyright © 2012, Oracle and/or its affiliates. All rights reserved.
- 15. Web Services Policy – WS-Policy
WSP: Web Service Policy 1.5 – Framework & Attachment
W3C Recommendation for an XML syntax to describe the
requirements and capabilities of a web service.
Defines the concept of an ‘assertion’ and how to declare policy
alternatives.
Examples :-
– Security
– Transactions
– Reliable Messaging
– Addressing

- 16. Web Services Security Policy –
WS-SecurityPolicy
WSSP: WS-SecurityPolicy 1.3
OASIS Specification for WSS related policy assertions
Service can specify which token profiles are required or supported
Service can specify which transport protocols are required or
supported
Declared in the service WSDL
16 Copyright © 2012, Oracle and/or its affiliates. All rights reserved.

- 19. WSS in OTM v6.2 - Inbound
Partial support for Username Token Profile
Full support for HTTP and HTTPS
Not declared in WSDL
Password Digest was initially supported but may be removed
19 Copyright © 2012, Oracle and/or its affiliates. All rights reserved.
- 20. WSS in OTM v6.2 - Outbound
Partial support for Username Token Profile
Full support for HTTP and HTTPS
External WSDL is not parsed for WSSP assertions
Password Digest was initially supported but may be removed
Requires settings on Web Service and External System records in
OTM.
20 Copyright © 2012, Oracle and/or its affiliates. All rights reserved.
- 23. WSS in OTM v6.3 - Inbound
Full support for Username Token Profile (except Password Digest type)
Full support for HTTP and HTTPS
Full support for Message Encryption
Declares security policy in WSDL for inbound services
– Defaults to Username Token over HTTPS
– Policy can be customised

- 25. Custom Policy
Installation deploys a policy file for each web service
– <otm home>/glog/glog_resources/policies/<service name>-Policy.xml
– For example,
<otm home>/glog/glog_resources/policies/IntXmlService-Policy.xml
To override default policy – DO NOT EDIT base file
– Create file under configured custom directory, for example
<otm home>/glog/glog_resources/custom/policies/IntXmlService-
Policy.xml
25 Copyright © 2012, Oracle and/or its affiliates. All rights reserved.
- 26. Custom Policy (contd.)
Sample files installed
– otm-default-policy.xml
policy installed by default (currently Username Token over HTTPS)
– otm-Wssp1.2-2007-Https-UsernameToken-Plain.template.xml
– otm-Wssp1.2-2007-UsernameToken-Plain.template.xml
– otm-Wssp1.2-
wss10_username_token_with_message_protection_policy.template.xml
26 Copyright © 2012, Oracle and/or its affiliates. All rights reserved.
- 27. WSS in OTM v6.3 – Outbound
Full support for Username Token Profile (except Password Digest type)
Full support for HTTP and HTTPS
Full support for Message Encryption
WebLogic Server handles parsing of policy assertions
– Requires additional WebLogic Server administration
All pre-existing outbound Web Services defined in OTM will operate
according to v6.2 logic i.e. will not automatically have access to v6.3
capability
27 Copyright © 2012, Oracle and/or its affiliates. All rights reserved.
- 28. WSS in OTM v6.3 – Outbound (contd.)
WSDL Document content needs to be URL
Existing records would not contain any WS-Policy details and so need
to be reloaded.
Use of Message Encryption requires additional administration tasks.
– Storage of external X.509 Certificate in WebLogic keystore
– New Web Service Security Configuration via Console (or config.xml)
– Configure OTM property to match keystore alias to service endpoint
glog.webservice.pki.alias.myalias=https://myserver/services/myEncrypti
