This upgrade has been a hoot. Turns out that POI dropped support for
setColumnWidth(jshort,jshort) at version 3.14. The preferred and only
method for this now is setColumnWidth(jint,jint). You've been warned.

Subject: POI HSSF Windows Server X11 error resolved
Sent by: "JAVA400-L" <java400-l-bounces@xxxxxxxxxxxx>
We're currently running the Jakarta POI HSSF Excel generation java methods,
version 3.10.1. I attempted to replace this with the current version,
which is 3.14. Identical programs on different IBM i servers reacted
differently to this upgrade. Some worked as on the previous version, but
our production server blew up on an error about Windows Server X11 could
not be located. I found that some other install had created an environment
variable "DISPLAY" with an attribute of "localhost:10" on the production
server. Removing this environment variable let the new version (3.14) work
correctly. This DISPLAY variable has something to do with defining a
display device to Java, which I presume does not exist for an IBM i job
running in batch.
I'm posting this for someone else that may have experienced a similar
issue, so that it might help you.
