Allows Existing RPG/Cobol applications to
be deployed on an application server.



Conversion occurs during development not
at run

time.


Allows customization in DDS.

Java Beans


All of the required objects are placed in a
WAR file.(Web Application Archive)


The WAR File is deployed/installed onto
the Application Server.(WebSphere,
Tomcat….on a xSeries, iSeries, zSeries…)

What Does Webfacing

Do For Me?


Allows me to add a browser based interface
to an existing application in minutes.


Allows one program to support browser
based clients
and

green
-
screen clients.


Allows existing staff to develop browser
based applications in RPG/Cobol while
learning Java.

How Much Does Webfacing
Cost?



User Time
-

WebFaced/Java applications
are slower than Green
-
Screen applications


Interactive CPU
-

WebFaced applications
run as interactive jobs. (300 CPW min)


Requires an Application Server


Tomcat
-

“Free” (You get what you pay for)


WAS Express as low as $500.00 for 20 users

Summary


IBM wants you to use WebSphere. Over the
next year, IBM will be spending $500
million dollars to put WebSphere based
solutions in front of Small/Medium sized
businesses.


IBM provides tools to iSeries users that cost
thousands on other platforms.


WebFacing is an ideal entry method into the
WebSphere environment.
