<section title="Introduction">
<p>
A number of people are using POI for a variety of purposes. As with
any new API or technology, the first question people generally ask
is not "how can I" but rather "Who else is doing what I'm about to
do?" This is understandable with the abismal success rate in the
software business. These case statements are meant to help create
confidence and understanding.
</p>
</section>
<section title="Submitting a Case Study">
<p>
We are actively seeking case studies for this page (after all it
just started). Andy Oliver (acoliver at apache dot org) has
agreed to have a few T-Shirts printed with the POI logo (once its
chosen) for the first
few best submissions. To submit a case study, either
<link href="http://jakarta.apache.org/poi/getinvolved/index.html">
submit a patch for this page</link> (preferred) or email it to the
<link href="http://jakarta.apache.org/site/mail.html">mailing list
</link>.
</p>
</section>
<section title="Case Studies">
<section title="Edwards And Kelcey Technology">
<p>
Edwards and Kelcey Technology (http://www.ekcorp.com/) developed a
Facility
Managament and Maintenance System for the Telecommunications industry
based
on Turbine and Velocity. Originally the invoicing was done with a simple
CVS
sheet which was then marked up by accounts and customized for each client.
As growth has been consistent with the application, the requirement for
invoices that need not be touched by hand increased. POI provided the
solution to this issue, integrating easily and transparently into the
system. POI HSSF was used to create the invoices directly from the server
in
Excel 97 format and now services over 150 unique invoices per month.

<faqs title="Frequently Asked Questions">
<faq>
<question>
What is the HSSF "eventmodel"?
</question>
<answer>
The HSSF eventmodel package is a new API for reading XLS files more efficiently. It does
require more knowledge on the part of the user, but reduces memory consumption by more than
tenfold. It is based on the AWT event model in combination with SAX. If you need read-only
access to a given XLS file, this is the best way to do it.
</answer>
</faq>
<faq>
<question>
Why can't read the document I created using Star Office 5.1?
</question>
<answer>
Star Office 5.1 writes some records using the older BIFF standard. This causes some problems
with POI which supports only BIFF8.
</answer>
</faq>
<faq>
<question>
Why am I getting an exception each time I attempt to read my spreadsheet?
</question>
<answer>
It's possible your spreadsheet contains a feature that is not currently supported by HSSF.
For example - spreadsheets containing cells with rich text are not currently supported.
</answer>
</faq>
<faq>
<question>
Does HSSF support protected spreadsheets?
</question>
<answer>
Protecting a spreadsheet encripts it. We wont touch encription because we're not legally educated
and don't understand the full implications of trying to implement this. If you wish to have a go
at this feel free to add it as a plugin module. We wont be hosting it here however.
</answer>
</faq>
<faq>
<question>
How do you tell if a field contains a date with HSSF?
</question>
<answer>
Excel stores dates as numbers therefore the only way to determine if a cell is
actually stored as a date is to look at the formatting. This solution from
Jason Hoffman:
<p>
Okay, here is a little code I used to determine if the cell was a number or
date, and then format appropriately. I hope it helps. I keep meaning to
submit a patch with the helper method below.... but just haven't had a
chance.
</p>
<source>
/////// code snippet ////////////
case HSSFCell.CELL_TYPE_NUMERIC:
double d = cell.getNumericCellValue();
// test if a date!
if (isCellDateFormatted(cell)) {
// format in form of M/D/YY
cal.setTime(HSSFDateUtil.getJavaDate(d));
cellText =
(String.valueOf(cal.get(Calendar.YEAR))).substring(2);
cellText = cal.get(Calendar.MONTH)+1 + "/" +
cal.get(Calendar.DAY_OF_MONTH) + "/" +
cellText;
}
/////// end code snippet ////////////
// HELPER METHOD BELOW TO DETERMINE IF DATE
// method to determine if the cell is a date, versus a number...
public static boolean isCellDateFormatted(HSSFCell cell) {
boolean bDate = false;
double d = cell.getNumericCellValue();
if ( HSSFDateUtil.isValidExcelDate(d) ) {
HSSFCellStyle style = cell.getCellStyle();
int i = style.getDataFormat();

<title>Project History</title>

<body>
<section title="Brief Project History">
<p>The POI project was dreamed up back around April 2001, when
Andy Oliver landed a short term contract to do Java-based
reporting to Excel. He'd done this project a few times before
and knew right where to look for the tools he needed.
Ironically, the API he used to use had skyrocketed from around
$300 ($US) to around $10K ($US). He figured it would take two
people around six months to write an Excel port so he
recommended the client fork out the $10K.
</p>
<p>Around June 2001, Andy started thinking how great it would
be to have an open source Java tool to do this and, while he
had some spare time, he started on the project and learned
about OLE 2 Compound Document Format. After hitting some real
stumpers he realized he'd need help. He posted a message to
his local Java User's Group (JUG) and asked if anyone else
would be interested. He lucked out and the most talented Java
programmer he'd ever met, Marc Johnson, joined the project. He
ran rings around Andy at porting OLE 2 CDF and rewrote his
skeletal code into a more sophisticated library. It took Marc
a few iterations to get something they were happy with.
</p>
<p>While Marc worked on that, Andy ported XLS to Java, based
on Marc's library. Several users wrote in asking to read XLS
(not just write as had originally been planned) and one user
had special requests for a different use for POIFS. Before
long, the project scope had tripled. POI 1.0 was released a
month later than planned, but with far more features. Marc
quickly wrote the serializer framework and HSSF Serializer in
record time and Andy banged out more documentation and worked
on making people aware of the project
</p>
<p> Shortly before the release, POI was fortunate to come into
contact with Nicola -Ken- Barrozzi who gave them samples for
the HSSF Serializer and help uncover its unfortunate bugs
(which were promptly fixed). More recently, Ken ported most
of the POI project documentation to XML from Andy's crappy
HTML docs he wrote with Star Office.
</p>
<p> Around the same time as the release, Glen Stampoultzis
joined the project. Glen was ticked off at Andy's flippant attitude
towards adding graphing to HSSF. Glen got so ticked off he decided to
grab a hammer and do it himself. Glen has already become an integral
part of the POI development community; his contributions to HSSF have
already started making waves.
</p>
<p>Somewhere in there we decided to finally submit the project
to <link href="http://xml.apache.org/cocoon">The Apache
Cocoon Project</link>, only to discover the project had
outgrown fitting nicely into just Cocoon long ago.
Furthermore, Andy started eyeing other projects he'd like to
see POI functionality added to. So it was decided to donate
the Serializers and Generators to Cocoon, other POI
integration components to other projects, and the POI APIs
would become part of Jakarta. It was a bumpy road but it
looks like everything turned out since you're reading this!
</p>
</section>
<section title="What's next for POI">
<p>First we'll tackle this from a project standpoint: Well, we
made an offer to Microsoft and Actuate (tongue in cheek
... well mostly) that we'd quit the project and retire if
they'd simply write us each a really large check. I've yet to
get a phone call or email so I'm assuming they're not going to
pay us to go away.
</p>
<p>Next, we've got some work to do here at Jakarta to finish
integrating POI into the community. Furthermore, we're
still transitioning the Serializer to Cocoon.
</p>
<p>HSSF, during the 2.0 cycle, will undergo a few
optimizations. We'll also be adding new features like a full
implementation of Formulas and custom text formats. We're
hoping to be able to generate smaller files by adding
write-support for RK, MulRK and MulBlank records. I'm also
going to work on a Cocoon 2 Generator. Currently, reading is
not very efficient in HSSF. This is mainly because in order to
write or modify, one needs to be able to update upstream
pointers to downstream data. To do this you have to have
everything between in memory. A Generator would allow SAX
events to be processed instead. (This will be based on the low
level structures). One of the great things about this is that,
you'll not only have a more efficient way to read the file,
you'll have a great way to use spreadsheets as XML data
sources.
</p>
<p>The HSSF Serializer, will further separate into a general
framework for creating serializers for other formats and the
HSSF Serializer specific implementation. (This is largely
already true). We'll also be adding support for features
already supported by HSSF (styles, fonts, text formats). We're
hoping to add support for formulas during this cycle.
</p>
<p>We're beginning to expand our scope yet again. If we could
do all of this for XLS files, what about Doc files or PPT
files? We're thinking that our next component (HDF - Horrible
Document Format) should follow the same pattern. We're hoping
that new blood will join the team and allow us to tackle this
even faster (in part because POIFS is already finished). But
maybe what we need most is you! </p>

<section title="Logo Contest">
<!--
<p>
The POI committers have voted to
<link href="http://jakarta.apache.org/ant">"innovate"</link> and hold a
logo contest. The big P at the top of the page is just a placeholder.
So the rules are pretty much this:
</p>
<ul>
<li>
<link href="http://burnallgifs.org/">Only PNG submissions</link>
be accepted (we can convert them as needed).
</li>
<li>
Submissions must be sent to the <link
href="http://jakarta.apache.org/site/mail.html">POI
User's mailing list</link> via an http link. If you do not
have an available webserver contact Andy (acoliver at apache dot
org) and ask him to post it for you (and he will if it doesn't
suck royally). Large binary attachments annoyingly posted to
the list will be rebuked. :-)
</li>
<li>
Image authors must be willing to work with us on any font and
sizing issues, etc.
</li>
<li>
All submissions become property of the Apache Software
Foundation to do whatever it wants with them (thanks!).
</li>
<li>
A non-binding poll will be taken and everyone can vote.
</li>
<li>
Based on the poll results and the fact that Andy won't vote for
anything that isn't some kind of tiki god or hawaiian theme
(maybe a poi pounder would be acceptable), the committers will
vote on the new POI logo.
</li>
<li>
Logos should be submitted in two flavors: one for the top of the
page and another for posting on other sites that note projects
that use POI technology.
</li>
<li>
The winner will get credit posted somewhere on the POI site and
have their logo used wherever POI is proudly served.
</li>
</ul>
<p>
You can see the current submissions <link
href="news/logocontest.html">here.</link>
</p> -->
<p>
Entries for the POI logo contest are now finished. Time to begin voting. Remember, Andy really
likes Tiki gods, but Glen suggests voting for what you like. :-)

</section>
<section title="Purpose">
<p>
The POI project consists of APIs for manipulating various file formats
based upon Microsoft's OLE 2 Compound Document format using pure Java.
</p>
<p>
OLE 2 Compound Document Format based files include most Microsoft Office
files such as XLS and DOC.
</p>
<p>
As a general policy we try to collaborate as much as possible with other projects to
provide this functionality. Examples include: <link href="http://xml.apache.org/cocoon">Cocoon</link> for
which you'll soon find generators and serializers for our projects;
<link href="http://www.openoffice.org">Open Office.org</link> with whom we collaborate in documenting the
XLS format; and <link href="http://jakarta.apache.org/lucene">Lucene</link> for which we'll soon have file
format interpretors. When practical, we donate components directly to those projects for POI-enabling them.
</p>
<section title="Why/when would I use POI?">
<p>
We'll tackle this on a component level. POI refers to the whole project.
</p>
<p>
So why should you use POIFS or HSSF?
</p>
<p>
You'd use POIFS if you had a document written in OLE 2 Compound Document Format, probably written using
MFC, that you needed to read in Java. Alternatively, you'd use POI to write OLE 2 Compound Document Format
if you needed to inter-operate with software running on the Windows platform. We are not just bragging when
we say that POIFS is the most complete and correct port of this file format to date!
</p>
<p>
You'd use HSSF if you needed to read or write an XLS (Excel) file using Java. You can also read and modify
spreadsheets using this API, although right now writing is more mature.
</p>
</section>
<section title="What does POI stand for?">
<p>
POI stands for Poor Obfuscation Implementation. Why would we name our project such a derogatory name? Well,
Microsoft's OLE 2 Compound Document Format is a poorly conceived thing. It is essentially an archive structured
much like the old DOS FAT filesystem. Redmond chose, instead of using tar, gzip, zip or arc, to invent their own
archive format that does not provide any standard encryption or compression, is not very appendable and is prone
to fragmentation.
</p>
<p>
Poi is also a Hawaiian delicacy that <link href="http://www.m-w.com">Merriam Webster's dictionary</link> defines as:
"A Hawaiian food of taro root cooked, pounded, and kneaded to a paste and often allowed to ferment." This seemed
strangely descriptive of the file format.
</p>
<p>
So if you like acronyms, then POI is an acronym. If you hate them, then we just used the name of the food for our
project. If you wish to signify your love or hate for acronyms, use POI or Poi to refer to the project respectively.
</p>
</section>
</section>
<section title="Components To Date">
<section title="Overview">
<p>A common misconception is that POI writes Excel files. POI is the name of the project. POI contains several
components, one of which, HSSF, writes Excel files. The following are components of the entire POI project
and a brief summary of their purpose.</p>
</section>
<section title="POIFS (POI Filesystem)">
<p>POIFS is the oldest and most stable part of the project. It is our port of the OLE 2 Compound Document Format to
pure Java. It supports both read and write functionality. All of our components ultimately rely on it by
definition. Please see <link href="../../poifs/index.html">the POIFS project page</link> for more information.</p>
</section>
<section title="HSSF (Horrible Spreadsheet Format)">
<p>HSSF is our port of the Microsoft Excel 97(-2002) file format (BIFF8) to pure Java. It supports read and write
capability. Please see <link href="../../hssf/index.html">the HSSF project page</link> for more information.</p>
</section>
<section title="HDF (Horrible Document Format)">
<p>HDF is our port of the Microsoft Word 97 file format to pure Java. It supports read and write capability.
Please see <link href="../../hdf/index.html">the HDF project page for more information</link>. This component is
in the early stages of design. Jump in!</p>
</section>
<section title="HPSF (Horrible Property Set Format)">
<p>HPSF is our port of the OLE 2 property set format to pure
Java. Property sets are mostly use to store a document's properties
(title, author, date of last modification etc.), but they can be used
for application-specific purposes as well. Currently HPSF supports
read functionality only. Please see <link
href="../../hpsf/index.html">the HPSF project page</link> for more
information.</p>

<section title="What happened to the HSSF Serializer?">
<p>The HSSF Serializer, which was part of our 1.0 release and last builds on
<link href="http://www.sourceforge.net/projects/poi">Sourceforge</link>, has been donated to the
<link href="http://xml.apache.org/cocoon/">Cocoon</link> project, and is available starting from version
2.0.2.</p>
</section>
<section title="Contributing ">
<p>
So you'd like to contribute to the project? Great! We need enthusiastic, hard-working, talented folks to help
us on the project in several areas. The first is bug reports and feature requests! The second is documentation -
we'll be at your every beck and call if you've got a critique or you'd like to contribute or otherwise improve
the documentation. We could especially use some help documenting the HSSF file format! Last, but not least, we
could use some binary crunching Java coders to chew through the convolution that characterizes Microsoft's file
formats and help us port new ones to a superior Java platform!
</p>
<p>So if you're motivated, ready, and have the time, join the mail lists and we'll be happy to help you get started on the
project!

These are articles/etc. posted about POI around the web. If you
see POI in the news or mentioned at least somewhat prominently
on a site (not your homepage that you put the work POI on in
order to get us to link you and by the why here is a picture of
your wife in kids) then send a patch to the list. In general
equal time will be given so please feel free to send inflamatory
defamation as well as favorable, technical and factual. Really
stupid things won't be mentioned (sorry).

<p>The POI project is the master project for developing pure

property sets to serialize their document objects.

This is an <strong>informal</strong> list - in chronological order -
of some of the noteworthy patches that have been posted
to the <code>developers</code> mailing list.
These patches are not (yet) part of the Poi project, but need reviewing for possible
inclusion. This system was instituted because, due to the large volume of mail and
the lack of time of the committers, some patches tended to get forgotten about. This
queue does not guarantee that any patch will be reviewed within a reasonable time frame,
but it does at least make them easier to find!
</p><p><strong>Reviewers wanted!</strong> - If you have time to review and/or test these patches,
we would be grateful for your time. Please post comments to the dev mailing lists.
</p><p>
Before submitting a patch, please read the page on <connect href="contrib.xml">Third-Party
Contributions</connect>. The preferred submission method for patches is:
</p><ul><li>Post to Poi developers list</li><li>Describe the patch, the reason for it and (if necessary) why this is important.</li><li>Generate the patch in <code>diff -u</code> format from CVS</li><li>Also generate a documentation patch or new file, if this is something that should be documented.
</li><li>Post as an attachment rather than inline (unless it is trivially small).</li></ul><p>Following the above guidelines will facilitate your patch being reviewed
and applied efficiently.</p></section><section title="Patch Queue"><p><strong> [Under Construction] </strong> Archive links will be added later.

<section title="Who we are">
<p>
The Poi Project operates on a meritocracy: the more you do, the more
responsibility you will obtain. This page lists all of the people who have
gone the extra mile and are Committers. If you would like to get involved,
the first step is to join the mailing lists.
</p>
<p>
We ask that you please do not send us emails privately asking for support.
We are non-paid volunteers who help out with the project and we do not
necessarily have the time or energy to help people on an individual basis.
Instead, we have set up mailing lists which often contain hundreds of
individuals who will help answer detailed requests for help. The benefit of
using mailing lists over private communication is that it is a shared
resource where others can also learn from common mistakes and as a
community we all grow together.
