1. CareWorks Consultants, Inc.
RPG to Java Conversion

2. CCI History
 Established in 1950
 CareWorks bought Compensation Consultants
Inc in 2006 and changed the name.
 Workers‟ compensation risk consulting and
claims management for nearly 30,000 Ohio
employers
 Started using GeneXus in 1992 (DOS Version!)
 200 employees, including case managers, field
staff, and an analysis group

3. Conversion Project
 CCI‟s systems manage all data related to their
clients and the workers that get injured on the job
 System was built entirely on RPG with iSeries
 Over 4,000 objects
 CCI was looking to convert to a web-based
technology
 Easier to train on a web-based system that newer
workforce members are familiar with
 Quicker access to data
 Improved integration with other business software
 Decided to use Java running on Websphere

4. Key Challenges
 Conversion vs. Rebuild
 Felt that a conversion was a shorter timeline
 Users would be more familiar after the launch with how
everything would work
 Could use the old system as a reference for testing and
comparison
 Stateless management of data
 RPG/iSeries - Kept the state of data from screen to screen
seamlessly
 Web – Is “stateless” and we had to find a way to carry
variables forward as if the state of a page in the past was
preserved
 Solution – GeneXus designed a session variables
management algorithm for us

5. Key Challenges
 Various commands that RPG used that Java generator did not
 „ASK‟ command – converted to pop ups („Which date?‟)
 „Cursor‟ command – User Control built to check field cursor is in
 Formatting of “green screen” to a web equivalent
 GeneXus supported us with an early version of Patterns
 Converted the 80-character format of RPG to approximate positioning of fields so
users were not too surprised after the conversion
 Converted Function Keys to buttons, Option numbers to Combo Boxes
 Performance
 RPG is fast and native to the iSeries – Can‟t be beat on performance!
 Java
 Initial challenges, but improved through stress testing (NEOLOAD)
 Memory management improvements
 Java version! Big win by using the IBM version of the Java toolkit.
 Process improvement. Doesn‟t matter if the system is slower if steps are
faster or fewer

11. Key Benefits
 Quick access to key information
 Diaries – All notes related to a business or claim are
always available
 Session variables allow easy movement from one screen to
another to allow a process to flow smoothly
 The business was forced to define their key processes
 Documented BCPs (Business Critical Processes)
 Multiple screens condensed into one
 They are now able to train more easily
 Business now looks more towards overall process
improvements rather than band aid fixes for everything

12. Next Steps
 Integration with imaging software (OnBase)
 Process restructuring continues
 Clean up stateless variable management as we can
 Users are having fun redesigning how their processes
work. Speeding up their days
 Using GeneXus controls for more efficient functionality.
 Re-developing modules from other environments into this
GeneXus application (Lotus Notes apps)
 Review and implementation of User Controls
 Looking towards potential mobile apps for field staff and
clients
