We use POI as well, the best place to start is the Quick Guide: http://jakarta.apache.org/poi/hssf/quick-guide.html Niall - Original Message - From: Wendy Smoak [EMAIL PROTECTED] To: Struts Users Mailing List [EMAIL PROTECTED] Sent: Thursday, March 11, 2004 6:37 PM Subject: RE: [OT] PDF generation (was: Reporting + Struts) Niall Pemberton wrote http://www.lowagie.com/iText/ BTW, I wasn't doing it in a web environment and the pdf generation is slow, can take up to 30 seconds for a large report.

I found this really helpful: http://jakarta.apache.org/poi/hssf/quick-guide.html It's their Busy Developers' Guide to HSSF Features and it gives you the complete needed to produce a worksheet to see each feature, one at a time. I got 95% of what I needed there, and the rest by studying the method signatures of the different classes. Hubert __ Do you Yahoo!? Yahoo!

Re: [OT] PDF generation (was: Reporting + Struts)
Wendy's post about this suggests that she isn't having a problem with it (120 pages in 7 seconds). To get a sexy looking grid on the page, with nice headers (multi-line, cell spaning stuff) we created our own TableRenderer based on iText's PdfPTableEvent - it handles drawing the headers and nice colored lines around all the cells. I think that slows it down quite a bit. As well as that, we wanted nice page headers and footers, with page numbering and ended up doing that through the PdfPageEvents. I think the combination of all that slows it down. Its probably not as bad as I think though - we currently generate a report by kicking of a batch script which starts up its own jvm and initializes a db framework - if I put it in a web app, that wouldn't happen every time, plus we could cache our report definitions - so maybe we would save a proportion of the 30 seconds. Thats next on my list after the current stuff I'm doing.

I am going to be putting If you think that is slow, wait till you try Apache's FOP. It's been a while, but IIRC, when my reports went five pages or more, I believe it took around 30 secs. With 50 pages, my users started calling and asking if the app was still running.

If that's slow too, ar e there other alternatives? __ Do you Yahoo!? Yahoo!
