Re: How do others configure classpath? - /Qibm/ProdData/Java400/ext

[johnking@xxxxxxx]

All,

 I wanted to resurrect this thread to find whether there is an emerging
consensus or "best practices" about where to store user-written java
programs.

 Numerous useful Java utility programs have been posted on these lists and
each seems to install in a different directory structure. Some load
directly off the /root, other install in /'javautil/whatever' and others
install in 'ext' under /QIBM/proddata/ or /QIBM/userdata/. Some processes
require maintenance to the CLASSPATH or environment variables. Judging
from the number of email posts, setting CLASSPATH is a major source of
frustration for both new and experienced users.

 I make no pretense about being an experienced sysadmin and am uneasy
about too many /root directories and too much fiddling around with
CLASSPATH. My first project, calling POI from RPG, was achieved by
placing the POI files in /QIBM/userdata/java400/ext". This worked because
'ext' is available by default and the POI package consisted of only two
.jar files.

 What about 'javamail', though? Is javamail enough of a well-recognized
app that it should have its own directory? If so, where should the
directory be located and should it be added to the *sys environment to
avoid CLASSPATH hassles?

 Our shop will surely be using Java more frequently in the future and it
would be good to start with a strategy in place. I'd hate to end up with
directories scattered all over the IFS and having to remember to do one
thing when calling Java from RPG, another in qshell and something
entirely different when submitting from CL.

 Would one of you gurus be kind enough to publish some pros and cons of
the various install strategies?

 Many thanks, JK
