Login or register to tag items

RPGtoJ2EE technology modernizes legacy iSeries (As/400) applications by fully transforming them into Java J2EE. The RPG code is transformed into Java Servlelts, JDBC/EJB data access and XML/XSLT for presentation of display and printer files.

RPGtoJ2EE technology employs both a transformation tool plugin to be used during the transformation activities of Analysis and transformation and a the RPGtoJ2EE runtime framework.

Transformation with RPGtoJ2EE provides the following benefits.

• Automated conversion of RPG to Java (J2EE)
• Reduces cost of hardware options
• Ultimate flexibility in deployment choices
• Automatic separation of application code into a modern
  3-tier architecture
• Substantially reduce time and cost compared to a redesign
  and rewrite effort.
• Future application enhancements can be introduced more
  easily
• Smoother transition path for AS/400 staff to Java.
• The “Fit” of the application to the business
  is retained
• Application functionality and familiarity to end users
  is retained
• On-going development option vs. one-time conversion
• Pluggable, layered approach
• Analysis tool that defines the transformation scope and identifies any “non-automatable” issues
• Data access (JDBC/JDO/EJB) to domain model (File/Format/Record)
• Domain model to Program (RPG-style Java programming)
• Program to Presentation (XML/XSLT)
• Servlet/Job Threading Model
