An iSeries developer’s roadmap Interface Web service Green screen Web browser Transport 5250 WebFacing Presentation and navigation Display file Struts/JSF Connectors JDBC, MQ, etc. Application logic RPG or COBOL program Session bean Physical or logical file 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. Embedded SQL Entity bean Interface to data store Database DB2/400
