J2EE and .NET Implications
 Programming Model
 Distribution
and components
 Presentation capabilities, thin/fat clients
 Database access
 Transaction coordination
 Naming and security
 Infrastructure
 J2EE: application server software for
Windows/UNIX/Mainframe
 .NET: Windows OS (2K+) and .NET server software

Inside the Fortress
Gate
Inbound and outbound message desks
Applications and services
 Applications use
application
server services
 Message desks
relay documents
to and from the
outside world
 Unified document
formats, transmission protocols and service
interfaces guarantee smooth operation
