Re: 3.0 release (and maven)
Hi Jörg, I'm replying this to the poi-dev list as well as poi-user. It seems that Nick (who is building the current POI 3.0 RC candidates) could use some help with Maven. http://issues.apache.org/bugzilla/show_bug.cgi?id=39977 --- Additional Comments From [EMAIL PROTECTED] 2007-04-10 02:50 --- What do we need to change to fix this? (I'm not a maven user myself) The pom file is auto-generated by the maven-dist ant task, based on a template that's in svn. Any patches to build.xml or the template poi.pom appreciated :) Are the guy? I hope so. A release would be sweet! BTW - I would be helpful to the guys clearing bugs before release if anyone who has submitted a bug in bugzilla would test against RC3 and provide a result. If your bug is still there, and you have not already done so, please provide a test case. I expect that large HSSF / lower memory impact is an RFE for 3,X or 4.0.

Re: Numeric Cell Type not consistent
Ah yes, the difference between being rational and precise :-D In programming fortran for IBM 370s you couldn't say: IF ( A.EQ.1.0 ) You had to say something like: IF ( ABS(A-1.0).LT.EPSILON ) where EPSILON = 0.0001 REALly My Finance Professor Father who compiled the first statistically reliable database of NYSE stock prices (Monthly 1925 - 1964 - the CRSP monthly database still maintained by the GSB at the University of Chicago ) has always remarked about the trouble he had when he had to convert to the IBM 360 in the early 60's. A REAL number went from being in a Word of 6 bytes of 6 bits to Words of 4 bytes of 8 bits. His dataset had to be converted from SINGLE to DOUBLE because the loss of precision of going from 36 bits to 32 bits adversely effected his results. A good computer scientist must know how precise their calculations are and make the trade offs. Takahiro is encountering the fact that different implementations have made their own decisions about numeric representations and it can be hard to know how POI's are different from Open Office or Microsoft's.

Re: HSSF - Generating large spreadsheets in streaming manner?
Accept state and follow Michael's suggestion (which is how we do it with our dynamic PPT, XLS and PDF) is to build the file and then serve the file's bytes. While the content is creating we show a progress with a continue working button, if that is clicked then we have a menu bar spot that tracks the progress and when the build thread has completed if the progress is still going the download proceeds automatically, if they have continued working then the menu bar updates to let them the document is ready and they can select it for download at their leisure. Heck according to ComputerWorld this approach defeats the recently discovered Adobe Reader web browsing vulnerability issue. Other technical reasons: IE tends to think it knows what type of file it is being served by looking at the beginning, guessing and then re-requesting the file. Do you want to be building that 50MB file twice? Most of us don't. This is the standards flogging trick that Microsoft used to beat Netscape with their first IE. Alternatively, if you are doing nothing except serving 50MB of data w/ o any style attributes then why not just serve up a CSV file? If you set the mime-type correctly that will stream out just fine.

Would you prefer that when you want to download ,say, a 50 MB zip file (which will take more than a second or two) off the internet that it follow the workflow you describe? The fact that the Excel spreadsheet is generated dynamically is an internal detail. Again, we're talking about a download that takes a few minutes and not hours.

In the situation you described, it would be better to tell the user that their request has been accepted and as soon as it is complete they will be notified through some other mechanism that they can download or view the results.

I think that having a streaming API would be very useful and its not because of trying to generate a massive non human readable spreadsheet. You have to factor in the time it takes to build that data to be used for the spreadsheet too. Consider a use case where a user is trying to download a spreadsheet with 500 - 1000 rows but the logic involved in getting the data for the spreadsheet takes around a minute. Without a streaming API, when a user tries to download such a file they click on the link and basically the browser waits for 1 minute and only then pops up a save dialog since the contents of the spreadsheet could only be written out to the response stream after the entire spreadsheet was generated. Had there been a streaming API, the contents could have been written to the response stream on the fly and a nice download dialog with progress bar would have displayed by the browser.

Yet people generate massive sheets in it. My pensiveness is that no human is likely to read such a large sheet or be able to do anything patricularly useful with it. So who are these sheets for? Often it turns out they are some kind of data transfer, which is frankly BAFFLING. Why?

Re: [NEW] - RE: Excel Sheet Title - Message is from an unknown sender
It is very important that: (1) You don't output anything to your response you setHeader and setContentType. response.setHeader(Content-disposition, attachment;filename= + file); response.setContentType( application/vnd.ms-excel ); (2) It is also important if using JSP in say Tomcat that you use a Servlet instead. JSPs are NOT intended for binary file types. The spec says text only. We get away with sending (1) through JSP, but you will get in big trouble with PDFs: (4) MS IE has sticky features for remembering download/save as/inline choices. I'm a MacOSX/Solaris user, avoiding windows and it seems to me that the place to undo these settings moves a lot. It is in a strange, non-web location in the other explorer - Windows Explorer that is reached from My Documents or My Computer You should use the most accurate mime-type possible. Avoid application/octet-stream - as some other website's interaction for a completely different unknown file type could cause stickiness later. If the user decides on certain settings he could defeat all of your attempts. I suggest that you avoid automatic choices. (5) Inline vs. attachment Using inline for excel and ppt will avoid the download and, if the files are very large, may make it look like nothing is happening. I would not use inline unless your client requires it. I've learned all of this the hard way Good luck.

Re: HSLF
Hi, I'm sure that others will answer with the details, but yes you can generate PPT w/o PowerPoint from java using POI. Styles are possible and so are object oriented graphics, tables, etc. My third party developer, Yegor, has extended POI to do a lot of this and has been making contributions to POI through Nick. Regards, Dave Fisher I am new in this mailinglist, but I am thinking of using POI for a project and have several questions! I wanna generate out of Java a Powerpoint file! But I cant find HSLF in any Jar-File, where can I download that? Is it necessary to have Powerpoint on the Server to generate it? or do i dont need to have Powerpoint to generate it? just for viewing? is it possible to give that powerpoint a style? because i didnt find a real documentation for hslf yet! so far! thanks for helping regards tom - To unsubscribe, e-mail: [EMAIL PROTECTED] Mailing List: http://jakarta.apache.org/site/mail2.html#poi The Apache Jakarta Poi Project: http://jakarta.apache.org/poi/ - To unsubscribe, e-mail: [EMAIL PROTECTED] Mailing List: http://jakarta.apache.org/site/mail2.html#poi The Apache Jakarta Poi Project: http://jakarta.apache.org/poi/
Re: Servlet and Excel
Hi Daniele,
I think I can help. Here is an example using tomcat.
(1) In Tomcat 4.1.31, in your web.xml
servlet
servlet-namemodelxls/servlet-name
servlet-classcom.pathtoyour.XlsServlet/servlet-class
/servlet
servlet-mapping
servlet-namemodelxls/servlet-name
url-pattern/yourxls.jsp/url-pattern
/servlet-mapping
The url-pattern doesn't have to be yourxls.jsp, it could be *.xls or
xls/*, etc.
(2) Your xls servlet.
public class XlsServlet extends HttpServlet {
public void doGet(HttpServletRequest request,
HttpServletResponse response) throws ServletException, IOException {
response.setContentType(application/vnd.ms-excel);
response.setHeader(Content-disposition,
inline;filename=+whatever+.xls);
// output your poi output to response.getOutputStream()\
...
My experience indicates that this is the best Content Type and
Disposition. You can change inline to attachment if you want to
try to force the save as dialog. Note that I say try, as user's IE
settings can get in the way and the only way to fix that is to go to
the other Explorer - Windows Explorer and change the way that
the .xls files (application/vnd.ms-excel) are Viewed.
Good luck.
Regards,
Dave

Can you explain what you mean by responding with a jsp page a
little more.
I have some code that will send back the spreadsheet into an IE
browser for
display, but it wants the whole screen. I can also send it as a
file for
download.

Hi
I need to find an example on how to produce an Excel file from a
servlet
and how to send it to the user responding with a jsp page. Does anyone
know where can I find a similar example?
Thank you
Daniele
