RE: Dynamic java for Excel spreadsheet

If you're generating spreadsheets via RPG jobs you may want to consider a 3rd party tool such as our RPG2SQL Toolset for this.

We have export CL commands and an RPG service program you can use for simple exports and programmatic spreadsheet building.

Since we utilize Excel on a connected PC, there's no memory issues unless of course the PC has issues.

An alternative worth considering.

Feel free to request a 30-day demo from our web site.

We have run into various memory and performance issues using the JNI
interface from RPG to Java to generate spreadsheets using the POI HSSF
API's. Sometimes to get around this, we generate the spreadsheet in a .CSV
format, but this obviously generates a pretty ugly output when imported
into Excel. I'm currently researching generating the java code dynamically
in an RPG program, compiling it, and running that, meaning that the there
would be at least one java code source record for every cell on the
spreadsheet. I believe that the resulting program would perform much
better than the JNI interface does. Does anyone see any show stoppers with
this approach? Anyone tried something like this before?
