There are 2 slides, firstly an iSeries version and secondly a Unix version.
The red arrows indicate the ‘legacy’ setup. In the iSeries environment I would count WebFacing as ‘legacy’.
The blue arrows indicate first steps towards a J2EE deployment using either Struts or Java ServerFaces. The need arises at this stage to decouple the 5250 interface from its accompanying back end logic, but this work should require no new skills. Navigation and presentation are taken over by Struts or JSF, interfacing with the back end logic via appropriate connector technology (JDBC+stored procedures, MQ, etc.). This is the point at which IDE (e.g. Eclipse) and Java skills start to be acquired. There is little requirement at this stage for detailed OO understanding, since the vast majority of the code is either generated automatically by the Java IDE or remains within the legacy code base (‘thin layer of Java, fat layer of RPG’).
The green arrows indicate J2EE Enterprise JavaBeans deployment. Here the logic has been migrated to session beans, and the data is held as entity beans, persistence involving storage within the existing relational database. At this stage there is a need for detailed OO understanding and extensive Java skills.

15. Domestic & General – Domino - 1999
CHALLENGE
D&G, a long time Logicalis customer, is a leading provider of domestic appliance and central heating breakdown services
Their second Web initiative was a Web self-service application integrated with their AS/400 back end, aimed at delivering domestic appliance repairer information to the general public (
Their first Web initiative, while successful, had had major project and technical issues
SOLUTION
Make use of Logicalis’ Web-AS/400 integration expertise, together with its Domino development and Web project management expertise

16. Domestic & General – WebSphere - 2004
CHALLENGE
To design and implement a user-friendly Campaign Management solution
To leverage the existing enormous and highly complex DB2/400 data repository
Highly functional graphical interface delivered in applet form
SOLUTION
Web-based solution built around the IBM WebSphere Application Server and WebSphere MQ products running on an iSeries platform
This provides the basis for a Service Oriented Architecture (SOA) enabling the new web applications to utilise the customer’s existing investment in legacy RPG technology
