– The age of Web Services. WS-I.ORG
A Fantastically Fertile Field of
Opportunity
• Tough Times Lay Down Compost

April 2, 1997: Sun Announced EBJs
June 15, 1999: J2EE Announced
December 8, 1999: J2EE Platform Ships
January 31. 2002: Java 2 SDK Enterprise Edition, Version

third tier)

Scott McNealy’s View: We’ve been doing it all along
Sorry, Scott but you are wrong
The sad, sorry, saga of ebXML
Where the real action is:
– SOAP, WSDL, UDDI
– IBM and Microsoft Drive the Stack
– WS-I.ORG
• Built in vs. Bolted On. Pet Shop Disaster
• Web Service in J2EE 1.4
Benchmarks
• Middleware Company. Leading J2EE
consulting firm.
• www.middleware-company.com
• Hosts of www.TheServerSide.com
• Leading Java Community Web Site.
The Present and Future State of
the Java Platform
• J2EE 1.3 (and EJB 2.0)
– Rounds things out (e.g. JCA, Message Beans)
– Partially addresses performance issues with Enterprise Java
Beans in general, entity beans in particular
– A (very) thin smear of web services
• J2EE 1.4
– Various incremental improvements
• I/O, JFC updates, long-term persistence, printing, etc.
– More web services stuff
• J2EE Beyond 1.4
– Where does the platform go from here?
– Vendors going their own ways?
– Tools?

Just What the Heck is .NET
Anyway?
• Understanding .NET can be be a bit tricky, because Microsoft uses the
name in several different ways.
– As the brand name for the latest version on the Microsoft serverside approach generally
– As the brand name for Microsoft’s server software products in
particular
– In the context of Microsoft’s own approach to web services
– . NET binary technologies

A Bit of .NET History
• Builds on, but also goes beyond the COM/COM+/DNA
legacy foundation
• More than four years in development
• Not a reaction to Java
• XML and web services were designed in early in the
process
.NET Myths and .NET Realities
“Proof by Repeated Assertion”
• Myth: Unlike Java .NET is Proprietary
– Reality:.NETTM is no more proprietary than J2EE TM
• Myth: Unlike Java, .NET is not a standard
– Reality: Key parts of .NET are standards – Java, however, is not
• .Net is not scalable, reliable, secure
– Reality: .Net implementations, properly done, are at least as
scalable, reliable, and secure as anything J2EE, correctly done
• .Net is not a reliable platform for industrial strength
systems in the enterprise
– Reality: .NET is at least as well suited for the job as is J2EE
• .Net is Windows Specific
– Reality: Myth of Lock-in and Portability
The Truth About Vendor Lock-in
• No technology, regardless of the promises made for it, truly delivers
complete platform independence. This is a fantasy. The truth is that
any non-trivial application systems will end up locked into one vendor
or more vendors’ products. The issue is not that of zero lock-in, but of
which vendors you prefer to lock-in with.
• With J2EE, you will in fact end up with substantial lock-in, not only to
some particular vendor’s J2EE application server suite, but to some
particular operating system as well.
• With .NET, you will certainly lock-in with Microsoft Windows – but
you become free to choose your server hardware from any vendor that
sells servers, with only two exceptions: Apple and Sun.
The Tools Dimension, Languages, and
Roles of C#, VB, and so forth
• Practically speaking, tools matter – and a lot, too!
• Anders Hejlberg has long been associated with the best
tools in the business outside Microsoft. And for the past
four years, he’s been working on .NET and C# at
Microsoft.
• Reusability of code is nice – but reusability of the IT skills
people actually have can often deliver even more
immediate substantial business value.
• C#, VB.NET, ASP.NET, Cobal.Net, etc.
.NET and Web Services
• .NET and Microsoft’s initiatives are very closely linked
• There is, however, no necessary connection between .NET and the
IBM/MicroSoft web services protocol stack (WS-1.ORG).
• .NET will, for most organizations, provide the most effective platform
from which to build and to consume web services simply by virtue of
offering the most immediately accessible, practical, understandable
way to do so.
• XML and web services are not bolted on to .NET. They are built in at a
very deep level. This is a key practical advantage that .NET has over
J2EE.
Some Basic Facts Beneath the
Choices
• Costs do matter
• There is no reason to choose a more complex, costlier
option over a simpler, less expensive one
• Good enough is good enough
Conditions Favoring .NET
•
•
•
•
•
Business requirements can be adequately met using Wintel servers
Cost minimization is a top priority
Existing Windows-based server infrastructure is in place
Windows deployment and administration skills are readily available
Business experienced Basic, C, C++, COBAL, etc. programmers
readily available
• Integration with MS Office applications is advantageous
• Rapid responses to changing business requirements is critical
A Simple Decision Model for
Choosing Between J2EE and .Net
• If circumstances absolutely require or strongly favor using
J2EE, then use J2EE
• Otherwise use .NET
• It really is that simple!
• Absent compelling business reasons favoring J2EE, .NET
will generally be the lower cost, more agile option offering
the best overall return for IT dollars invested
