Hi Paulo/Bruno,

   You guys have been really awesome and helpful through out our PDF report
generation development.
The development is totally completed and we are doing some
load/stress/performance testing for PDF reports. We are encountering lot of
issues during out tests in the test environments.

   Issues like,

  1. Most of these reports are more than 500 pages. Depending on the
criteria that customer had selected in the UI report may vary from 500 -
3000 pages of PDF. what happens now is that it takes around 15 mins for this
3000 page report and around 7 mins for 500 page report and during the PDF
report generation process it consumes all the heap and load averages on the
servers goes more than 7.0. Everybody in my team says that this is
unacceptable and I have been really struggling to make them understand that
PDF generation is always a complex process because it has to generate binary
data.

  2. I have done everything that I could to improve from application code
perspective but there is no big change in performance. 

 So that's the reason I thought I will send you both an email and explain
the issues that we have over here and get some good ideas. We have invested
lot of time into this project for PDF report generation and so I have lot of
pressure from my management to find a solution. We use to have a web
reporting tool from IBI called webfocus for PDF report generation and that
takes only 50% of the time that iText takes. We are getting rid of webfocus
and converting all the reports to stored procedures. 

   I have couple more questions, can we generate PDF report in chunks what I
mean is generate 20 pages at a time and stream it back and then generate
next 20 pages some thing like that??

  And also is it better to generate a PDF report dynamically or write it to
a temporary location and then read it from there???

I will really wait for your reply.

Thanks & regards,
Madhu Vempati.

If you are looking for an iText analogy with <A HREF="...">,
you can use the Anchor-object. If you want to change the appearance
of the clickable text, try experimenting with the Font.
see http://www.lowagie.com/iText/tutorial/ch03.html#anchor
for more info.
