You're right, the first one was pretty old. However, the error from SQL2JXLC was from a v5r4 machine on 10/25/2009, and it says the reason for the error was "3 -- Failed spawn of child process."

And you're right, my current problem is that it can't find the file. However, since I can copy & paste the path and open the file with DSPLNK, I know 2 things -- 1) there is no error in the path, and 2) I have permission to open the file.

But when I run an RPGLE program that uses the same path to open the file with hssf_open, it fails. It fails only if the file is in a particular folder, to which *PUBLIC has no authority, but to which I do have authority.

If I move the file to another folder (also in QNTC), the RPGLE program can open it just fine.

The message this time doesn't show any of that. It just says it can't
find the file. That implies there's either an error in the path or
there's a permissions error.

The archive message thread was from V4Rx. With V5Rx, the jvm runs in a
thread in the same job as the RPG program that calls it. You can verify
this by looking at WRKJOB option 20. You should see something like this:

Hi Dan,

In this case, my user profile does have authority to the file in
question -- I can open it with DSPLNK.

The reason I think there's a batch interactive job involved has to do
with this old thread that solved a problem for me some time ago:
http://archive.midrange.com/java400-l/200303/msg00060.html

After that, I was using SQL2JXL and got this message:

The relevant part being: "3 -- Failed spawn of child process." which
means this was running in a job queue or subsystem that only allowed 1
job at a time (i.e. single-threaded).

I'm looking at this job log for an RPG program we have that calls java
methods.

QNTC is pretty flaky. You'll (your user profile name) have to have
permission to the file in the Windows directory and you'll have to
have permission to the Windows share, besides having permission to the
symlink you describe. That means you have to have the same user id set
up as a user profile on the machine where the share lives and that
user has to be granted authority to read and write the file.

Subject: Using HSSF POI to open file in QNTC

Hi Everyone,

I'm using Scott Klement's HSSFR4 service program to open a spreadsheet
in a folder on a Windows box to which my userid/pswd has authority
(i.e.
I can open it via WRKLNK option 5), yet when my RPGLE program tries to
open it with the HSSF_Open procedure, it fails with:

RNX0301
Message . . . . : Java exception received when calling Java method.
Cause . . . . . : RPG procedure HSSF_OPEN in program UTLIB/HSSFR4
received
Java exception "java.io.FileNotFoundException: Permission denied.
/J/Accounting/FRG/ICG/Product Master Maint Template.xls" when
calling method
"<init>" with signature "(Ljava.lang.String;)V" in class
"java.io.FileInputStream".

Note that "/J" is a symbolic link to "/QNTC/MyServer/MyFolder" (names
change blah blah). This does not appear to be a factor. If I move
the spreadsheet to another directory within "/J" to which *PUBLIC has
*RW authority, it opens just fine.

My theory is that the class "java.io.FileInputStream" is actually
running in a batch interactive job spawned from my job, and that batch
interactive job is running under QUSER or some other userid that does
not have authority to the "/J/Accounting" folder.

My questions are 1) is my theory correct? 2) how can I see what user
the batch interactive job is actually using? and 3) is there a way to
have the batch interactive job use my userid/pswd?

tia,
