Do you want
to develop a reporting capability within java based application? I have shared
my knowledge/experience on reporting projects which I have worked earlier.
Happy to hear if from you if you have any concerns/suggestions.
To work with PDF Reports:
We have
used FOP and iText earlier (not both in a same project) to create a pdf report
using Java. Please read the below for each of its pros and cons.
FOP:
It is an
open source Java API to create a PDF report dynamically in a template format.
If you have a XML data and formatting object template (xsl), creating PDF
report using FOP is very easy. I would
say only 3 lines of code will help you to create a PDF report.
XSLFO is a
XSL formatting objects and can be used for formatting XML data and to generate
PDF report. Using FOP, it is easy for us to generate a read-only pdf. At the
same time, we can’t alter an existing pdf or we can’t apply any security within
a pdf using FOP. Want to know more? Have a look @ http://www.codeproject.com/Articles/37663/PDF-Geneartion-using-XSLFO-and-FOP
iText:
It is an
open-source and more powerful java api for creating a PDF file using java.
Using iText, developers can create a PDF file with digital signature and
security (including having permission for opening a document, print/copy the
pdf). In addition to that, we can manipulate, split and concatenate the
existing PDF(s) within Java program. Also, we can build a form within PDF
document. Good set of working examples are available @ http://itextpdf.com/
You can
choose the right framework to address your pdf needs.
To work with Excel Reports:
We have
used POI and JExcel earlier (not both in a same project) to create a Microsoft xls
(spread sheet) report using Java. Please read the below for each of its pros
and cons.
POI:
It is an
open source Java API to read/write/modify Excel spread sheets dynamically if
you have a template already (xsl). Say implementing the POI will be very easy
if you already have the xml data response and xsl template for your report. As
I understand, POI is not improved as much like JExcel in terms of protecting
the xls spread sheet data. Want to learn more, please look at http://poi.apache.org
JExcel:
It is an open
source Java API to read/write/modify Excel spread sheets dynamically. If you
want to apply security OR to derive a new data (Sum, average etc) using the
existing data, JExcel will be the right option. It is a Java API, we wanted to
write Java code for column alignment, font, style etc. Also, it supports copying charts and images
into excel sheet. Want to know more? Visit http://jexcelapi.sourceforge.net/
If you
unable to follow the examples used in the above links, any issues or sample
codes, reach put to me.

Nice article man. Particularly it helped me to refresh the FOP stuff (our first project). Thanks for that.

No Problem Mr.Sakthi US.
You can let me know if you need any sample program for this.
