Live from the first day of the JAX:

Rod Johnson, SpringSource:
The Future of Enterprise Java

Does enterprise Java have a future?
Third answer: "No one will date a Java Programmer" biggrin.gif

Java market is not shrinking and still huge in comparison to e. g. Ruby.
Still growing, but there are strong competitive threats, and Java hasn't fully delivered on its promise, yet.

Forces for change


Six predictions for the future

The productivity challange

Enterprise Java slowed by "baggage",
conception is over 10 years old.

Need of a reaular clean out.

Java EE 6 is an attempt to clean
house; will come out late 2008 or eraly 2009.

Two new philosophies


Profile A - minimal, lightweight
- Tomcat

Key element: Servlet 3.0

biggest change relates to extensibility

extension at runtime instead of web.xml

Profile B - adds persistance
and two (?) component models

still relativaly lightweight

many points still unclear, like EJB
3.1 "lite" and Web Beans

Profile C - "Full platform"

Java EE "classic"

"Titan nuclear Missle of enterprise

Opposing forces: Modularity and Monopoly

Java EE 6 promotes modularity

Current AS market quite consolidated:
WebLogic + WebSphere ~70%

Both market leaders are part of much
bigger plays

Oracle: aggressive vertical play

IBM: services

Both see their Java middleware as part
of a Microsoft-like full-stack solution

How to measure the market?

old measurements are obsolete


1. Real competition will return
to the application server market

Bonus 1: Economic value will become
more aligned with what people actually use

2. Tomorrow's application server will
be lightweight and modular

3. Tomorrow's application server will
not merely implement JCP specifications

Bonus 2: The JCP will change to be run
through open source; Sun is becoming an open source company

4. The market will address the gap between
Tomcat and WebLogic/WebSphere

5. The gap between application servers
and ESBs will be bridged

6. The Black Knight will be defeated

EJB is dying

Why does it matter?

EJB is the centerpiece of "old

It's vital that it is put aside for
progress to be made


Wer are in for a period of rapid change

Java EE 6 may keep Java EE relevantt,
but Java doesn't really shape the future.

One of the key technologies that will
shape the future is OSGi

It will be an exciting time.
