I am trying to write to Excel spreadsheet from RPG program using code from Scott Clement article. POI Jar files that I downloaded are 3.5, not 3.1 that Scott used. I am getting error message:
Java exception "java.lang.UnsupportedClassVersionError:
org/apache/poi/hssf/usermodel/HSSFWorkbook" when calling method "<init>"
with signature "()V" in class "org.apache.poi.hssf.usermodel.HSSFWorkbook"
I know very little java. What can I do to fix it?
