this application.Would you please suggest me nessesary
steps,technologies,resourses which will be useful to me
for developing this applcication?

Dinesh

Hey,
The version of geotools is critical since *lots* has changed in the past
few months, let alone the past few years. The name of the geotools files
should give you the version.
>From your file it seems like you are using a geotools version prior to
2.0. Geotools 0.x/1.x was a very different design meant to be used in an
applet. That version is very, very old and few of us know much about it.
It's so old that you are probably better off looking at alternative
technologies.
What is your overall goal? To have a desktop client viewer (see uDig) or
to serve up a web page with a shapefile image (see Geoserver, MapServer,
OpenLayers...)?
