Re: Trying to get a RPG program to read a xlsx

For all the good Scott's API is - and it's most excellent - I've wondered about reading the XLSX directly. It is, after all, just a ZIP'd file of a bunch of XML files.

jar or 7-Zip on i can extract it to a directory - then there's a tree to maybe walk down some - if created by Microsoft Excel, each sheet is in a directory /xl/worksheets - sheet1.xml, for example.

Strings are held often in something called sharedstrings.xml - this is in /xl - it's a zero-based array of each text used in the workbook - the <sheetdata> section of the xml will have the index.

Personally I don't think this would be all that hard to read with, and it'd be a lot faster than all those individual Java calls from RPG.

Just a thought

I need help. I have loaded the POI and other libraries onto the machine and

I am stuck with an error trying to open the spreadsheet with the
hssf_Open(path_and_filename). It errors out and the job log shows that the
file is not found.


1. The file name and path is long, over 100 characters. Is this a
problem?

2. The file name contains blanks. Is this a problem?

3. I cannot debug the HSSFR4 code. The compiler jumps over it and will
not allow me to put in a break point. I am using the Java/GUI debugger
included with iAccess.


Any suggestions would help.

TIA
