Re: Family Tree web app problem with image map using Tapestry 4..
Hi,
I need to build a family tree maker based on web application using java,
would you help me and tell me the steps please ? I really appreciate if you
would help me to kick start this application.

Re: Family Tree web app problem with image map using Tapestry 4..
Posted by Alex Tian <al...@hotmail.com>.
I can hardly say it's just for fun...
put it short:
from the technical point of view, it demonstrates several things:
complex drawing algorithms to construct the family tree graph and a number
of advanced JSP/html techniques
from the business point of view, one could use it as the core system for
related business... the web site i recommended is a good example.
Dear Alex
I just did not understand the goal and objective of the family tree web
application ? is it only for fun ?
Speaking honestly, it's a tough one to do(though it's a really revolutionary
great topic), especially for undergraduates,
but one the other side, you might have more time than i had...
It took me 2 months to do it using a number of advanced java web
technologies and it was for my M.Sc. final project given 3-month time
constraint.
first thing I would suggest is do a google search on existing related web
apps
http://www.genesreunited.co.uk is a good example...
i just visited their web site 5 mins ago and found out that they ve got a
lot of things updated since my last visit which was over a year ago...
no better starting-point than a good backgound research...
then if u r still interested in it and would like to challenge it,
come back and i ll give u some more in-depth observations about that
project...
all i can say now is it is doable even in pure JSP, because more advanced
java framework makes things far more complex while providing better services
at the same time...
