Java reports a long stack of possible errors - the one you listed is described in many places - a google search was productive. The quote I posted is not about signatures - that is a different error. This one seems to be about the version supported by a class - that version would be of the JVM.

Of course, since this is being called in an RPG program, this should maybe to posted in the RPG list. Or in the Java list, since it is a Java error, not an RPG error. You'd get better help in the Java list, methinks.

Cause . . . . . : La procédure RPG XLCRTDEMO du programme FOXWELL/XLCRTDEMO a
reçu une erreur Java "java.lang.UnsupportedClassVersionError:
org/apache/poi/hssf/usermodel/HSSFWorkbook" en appelant
la méthode
"<ini"
avec la signature "" dans la classe
"org.apache.poi.hssf.usermodel.HSSFWorkbook".

Is it the version of JAVA on the i or the wrong version of
hssfr4.rpgle?
How do I check?
You'll be doing yourself and others a big favor by indicating the message ID associated with the error. You copied everything else but what we need.

sorry RNX0301.

It's the RPG procedure new_HSSFWorkbook() that fails. D new_HSSFWorkbook...
D PR like(HSSFWorkbook)
D ExtProc(*JAVA:
D 'org.apache.poi.hssf.usermodel-
D .HSSFWorkbook':
D *CONSTRUCTOR)

The message seems to indicate a problem of comparison of signatures.
