I'd like to build GIS applications in my job using free technologies.
I read that 2 great options are Geotools and Jump. I'd like to know the most important differences between one and the other options.

Jump is simply amazing on several levels - it is very easy to use and
get started developing. They have a quick guide to making a plugin in
for example, and it is easy to define your own Style object for
The geotools is a library (not a full GIS application) and is a bit
harder to get started with - it tends to depend on OGC/ISO standards.
It has really good support for data formats, but it would define styling
using "style layer descriptor" files (based on an XML schema from a
specification) rather than an Object.
Back in the spring we evaluated several platforms for the development of
a GIS application:
(The may or may not make interesting reading for you)
The resulting project (User Friendly Desktop Internet GIS) will be
complete at the end of the month, you can download latest version here:
Its main advantage is the ability to "Search and See", you can locate
free data published by web feature servers and web map servers and drag
them onto the screen.
There is also a really nice C++ based project that is gaining momentum
over the last year, and I have recently learned of several other Eclipse
Rich Client platform based GIS applications under development (none of
which are released quite yet).
It is also worth pointing out that all of this work builds on JTS, we
have a lot to thank Martin for (even projects that don't wear JTS on
their sleeve often use it behind the scenes to do the heavy lifting).
could someone provide me with the typical contents of a .prj file for
shapefiles...I generate several shapfiles well, but when I reimport them
in geotools message is given according to the fact there is no .prj
fils available (gt 2.1M1).
