Hi
We are going to create a large report (30 or 40 pages) for our company using
iText for Java. The report will have a lot of static data and images. The
report will also have dynamic data and graphs about the current logged in user.
I was wondering what the best way to handle the static data and images would
be. I have looked all over the internet and cannot find any articles on this
subject. I have also asked the question in a few forums with no real help.
These reports will need to be generated on the fly and returned to the user
immediately, so performance is a must. The report will be served up using a
Java Servlet in a web application.
These are some of my initial thoughts on how to solve the problem. I would
really like some input on what issues other people have had when doing a report
like this so I can write/design a good solid report that is easily maintained.
1.) We could create a PDF with all the static content and images. Then open
the PDF with Java and insert the dynamic content and graphs. Is there a way to
put place holders in the PDF that I could use with the Java to insert the
dynamic data and graphs (which would be images).
2.) Place the static data in a database and retrieve it whenever a report is
generated. To me the database design would be complex. It would have to take
into account pages, paragraphs, titles. It would also have to takes into
account images and the placement of the image on the page.
3.) We could put the static content in an XML file and cache the content in
the Servlet Context when it initializes. This might help with performance
issues. I would think we would still have the same design issues as the
database would have, but might be easier to maintain.
I am using the iText book as a reference, but did not see that it covered this
particular issue.
Thanks For Your Time
Doug
