ClearPath Java Role-Based Security
• Unisys value add integration
• Role-based Java Security between
JBoss and ClearPath
• Access permission assigned to roles,
new users get access permissions
based on their role
• Provides simplified administration
• Unified authentication between Java
and ClearPath

ClearPath OS 2200
Page 9
OS 2200 software SOA enablers
• Java
The right tool
for every job
– Native JVM implementation
– JBoss application server
– Resource adapters for RDMS, DMS,
TIP/HVTIP, DTP services, BIS
– Eclipse plug-ins
• Other OS 2200 SOA-enabling software
– OpenDTP (Open Distributed Transaction
Processing)
– MQseries
– DTI (Distributed Transaction Integrator)
– MSMQI (Interface to Microsoft Message Queuing)
– NTSI (Messaging Integration Services)
– CITA (Communications Interface for Transaction Applications)
– Third-party products for screen-scraping and ODBC access
Page 10
Java on OS 2200
• Java Virtual Machine
– Native implementation on OS 2200
– Integrated with OS 2200 security and file
systems
• JBoss
– Open source Java EE application server
– Validated, prepackaged and enhanced
for 2200 with security, transaction
integration and more
– Redhat-JBoss offers additional open source
products, including JBoss Enterprise
Middleware Suite (JEMS) – “The open source
platform for SOA.” They are also developing
an open source enterprise service bus.

Web Services
What are Web Services?
• Standardized way to implement
SOA over the Internet (or any
network)
• Based on XML files and
messages
– WSDL (Web Service Description
Language) to describe services
– SOAP (Simple Object Access
Protocol) to format messages
– Dozens of other standards at
varying levels of maturity
When should you use them?
• When you want the highest
degree of standardization,
platform independence, and
future flexibility
• When functionality is needed by
business partners, clients, and
suppliers who operate in a wide
variety of computing
environments
• When you have technology that
supports them, such as the Java
EE environment on OS 2200

Remember: SOA and Web
Services are NOT
synonymous!
Use native middleware…
• When you have no need to extend
the services outside the data center
and your internal, active networks
• When you have real-time
performance needs that cannot be
met in a Web Service environment
• When you have specific platform and
technology integration needs
• When you do not have Java
expertise but do have expertise in
direct use of these middleware
solutions
• When you are using distributed
transactions that span services

SOA provides the “Structural Abstraction” that links Business Architectures
to traditional IT Architectures (Application & Infrastructure)
Component Architecture
3D Blueprinting provides methods and frameworks to structure “services” at the Business
Process layer, Application Layer, and Infrastructure layer, providing a robust
and “aligned” SOA implementation across an implementation
