But it works, and there is no comparable RPG library. It would take quite a bit of work to make one that has the capabilities of POI. As Vern mentioned, you can make something that will work for your purposes, but then you need to understand the xlsx file structure, and adding new features is more work. If someone knows of something that is comparable, let me know. Maybe if there are enough interested parties, we could port something. Maybe there is something written in C or C++ out there that is compiled for PASE, or that can be ported to qshell?

Thanks, I missed that it passes back an unused object, but now that you say that, I see it in the Java docs.

For anyone who was following this thread, the following will
correctly provide all the required entries in hssf_h:
D AUTOFILTER_CLASS...
D c 'org.apache.poi.ss.usermodel-
D .AutoFilter'
D SSAutoFilter...
D S O CLASS(*JAVA
D : AUTOFILTER_CLASS)
D ssSheet_setAutoFilter...
D PR like(SSAutoFilter)
D EXTPROC(*JAVA: SHEET_CLASS
D :'setAutoFilter')
D ref like(CellRangeAddress) const
In the rpg program references as an example:
range = new_cellRangeAddress(0:10:0:4);
ssSheet_setAutoFilter(sheet:range);
The missing piece was provided by a gentleman in England
who figured out that the ssSheet_setAutoFilter needed a reference back
to SSAutofilter using the "like(SSAutoFilter)" as shown.

Well as you know ILE programs do not have to be homogenous as far as the
language goes. The procedure START_JVM is in Scott's HSSFR4 service
program, but I am calling it from my CLLE program STARTUPJVM. I use a
binding directory to provide the reference. It appears that I had to go
into the HSSFR4 source and put Export on the start_jvm procedure. I also
had to move the prototype for that procedure from hssfr4 to hssf_h (but
not to call it from my CLLP program). Then you should be able to make the
startupjvm program compile.

Mark,
Yes you are right about the typo. Range is defined correctly.
I'm actually using 3.12. However when I change my
CLLE to include the java_home to go to 626 and then run
java -version I get:
Directory /QOPENSYS/QIBM/PRODDATA/JAVAVM/JDK626/32BIT in
JAVA_HOME environment variable not found.
So I know that I've got something amiss/different from yours. (And yes
the above directory is there.)
Since you have a binding directory involved at the CLLE level, I'd be
interested in how
you implemented the START_JVM. Not something I had considered. Not
sure it will make a difference but I'd like to run that down. That's
pretty
interesting.

No, I'm using Java 6.
The Range should be defined as:
d range ... Like(CellRangeAddress);
But that may be a typo on your part since using RangeAddress vs.
CellRangeAddress would likely cause it to fail compile.
If I am sure of my definitions, I usually look at my JVM and environment
variables. If something gets hosed, you have to sign off, then sign back
on since you only get a single JVM per job and once it is corrupted you
need a new job to get a new JVM. I created a CL to start my JVM so I could
manage it manually, but eventually once I got things stable, I just put it
into my initial program. Here is my SETUPJVM CLP.

Note that procdure call to START_JVM which resides in HSSFR4. Also there
are some classes not found in POI since you only get one shot to declare
your classpath, and if that is wrong when you start your JVM, you need to
log off and log back on to get a new JVM. Unfortunately I have not found a
way to discover your current classpath, because it might not be what is in
the environment variable. Note, the environment variable can be changed,
but the class path is based on the value of the environment variable (or
maybe a command line option if you use runjava) at the time the jvm is
started. But if you use this simple setupjvm clp, then you know what it
is. Another advantage of a cl like this is you can call it in a batch
stream to set up the JVM for that job, and you know it is correct. Note,
this is my development clp, the production one uses POI 3.12.

Mark,
I'm back on my setAutoFilter problem.
After playing with different versions
including 3.7,3.11,3.12 I still have a problem
with the setAutoFilter showing up as an
invalid method. I got past the class not being
defined but now the error is:
"received Java exception "java.lang.NoSuchMethodError:
org/apache/poi/ss/usermodel/Sheet.setAutoFilter(Lorg/apache/poi/ss/util"
when calling method "setAutoFilter" with signature
"(Lorg.apache.poi.ss.util.CellRangeAddress;)V" in class
"org.apache.poi.ss.usermodel.Sheet".
The range is defined as D range ... like(RangeAddress)
The code is:
range = new_cellRangeAddress(0:100:0:4);
ssSheet_setAutoFilter(sheet:range);
hssf_h has been changed to include the setautofilter:
D SSSheet_setAutoFilter...
D PR EXTPROC(*JAVA: SHEET_CLASS
D :'setAutoFilter')
D ref like(CellRangeAddress) const
In your example you indicate that you are on 7.1.
So my question is a simple one: Do you think this would
have anything to do with my being on version 6.1 with java 6.0
instead of java 7?
Any help would be most appreciated.

First, you are correct about the call to new_cellRangeAddress(0,10,0,5);
should use : instead of , to separate parameters.
Second, to enable this, you only need to modify hssf_h.
Third, what is the error message, I am unsure what your problem is. Is
setAutoFilter not found in org.apache.poi.ss.usermodel.Sheet?
Do you have range declared as a Java Object?
dcl-s range Like(CellRangeAddress);
What does you code look like?

but that can be addedPOI does it starting with version 3.7, here is a Java example:
Workbook wb = new HSSFWorkbook(); //or new XSSFWorkbook();
Sheet sheet = wb.createSheet();
sheet.setAutoFilter(new CellRangeAddress(0,100,0,10));
Now, Scott's HSSF prototypes do not include the setAutoFilter method,
// ----------------------------------------------------------------
// ssSheet_setAutoFilter()
//
// sets an auto filter for a range of cells
// ref - a range to set the filter on
// ----------------------------------------------------------------
dcl-pr ssSheet_setAutoFilter
ExtProc(*JAVA
: SHEET_CLASS
: 'setAutoFilter');
ref Like(CellRangeAddress) const;
end-pr;
Call in RPG using HSSF this way to set auto filter on the first ten rows
and first five columns:
wb = new_XSSFWorkbook();
sheet = ss_newSheet(wb: 'Sheet1');
range = new_cellRangeAddress(0,10,0,5);
ssSheet_setAutoFilter(sheet: range);
Back in December Mark Murphy injected the above as a modification toMark Murphy

mmurphy@xxxxxxxxxxxxxxx
Scott's HSSF_h.
I'm wondering if Mark would elaborate on what he did.
I tried to add this addition to HSSF_h (using POI-3.11) and I'm not sure
what I'm missing
as far as modifications go because while compiling a program it says the
setAutoFilter
is not defined.
Also, I'm concerned that what's shown ...Address(0,10,0,5) probably
should be (0:10:0:5)
at least in the rpg code. Should there be entries in HSSF_h as well as
HSSF4?
D SSSheet_setAutoFilter...
D PR EXTPROC(*JAVA: SHEET_CLASS
D :'setAutoFilter')
D ref like(CellRangeAddress) const
Thanks!
