Re: POI HSSF Windows Server X11 error resolved

I can't say for sure but I thought you needed to run them headless when it is looking for an X Windows entry. Something like:

ADDENVVAR ENVVAR(QIBM_RPG_JAVA_PROPERTIES) +
VALUE('-Djava.awt.headless=true;+
-Dos400.awt.native=true;') +
REPLACE(*YES)

Not sure about your environment but I have used entries like this (in CL and Shells) to get past the DISPLAY problem.

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.
