To make this function work at all, you need MS-Excel (95 - 2003),
and/or the Java package > 1.2.6 plus either Apache POI > 3.5 or
JExcelAPI installed on your computer + proper javaclasspath set.
These interfaces are referred to as COM, POI and JXL, resp., and
are preferred in that order by default (depending on their
presence). For OOXML support, in addition to Apache POI support
you also need the following jars in your javaclasspath:
poi-ooxml-schemas-3.5.jar, xbean.jar and dom4j-1.6.1.jar (or later
versions).
Le problème est que je ne connais pas du tout Java et je ne suis pas du tout capable de comprendre quoi faire !!
