Have you developed an application based on the CHARVA library? If so, please send me
a project description, screenshots and/or a project logo and I will insert a link to your
project on this page.
"We are developing an open source cross platform installer framework. We have used charva
for the TextUI purpose in the project. .... Thanks for writing such an excellent library
which helped us a lot."
Sun Microsystems Inc.
"First I would like to thank you for all the work you must have put into
Charva. It really is a nice idea, implemented very well.... I am using Charva to provide
a text-mode administrative interface for our product which is a Linux-based server....
I decided I would use gcj (the GNU compiler for Java) to create a native executable.
The speed it runs at now is very impressive, you wouldn't know it was written in Java!"
"Our business unit CPP within the
SteelCompany Corus in Ijmuiden (Holland) uses
your Charva application now for 6 months with success and I want to thank you for
all the blood sweat and tears that you have put into the application. We are using
your application as a user-interface for our mobile terminals in cranes and trucks
and the application - which runs under AIX - proved itself as fast, stable and
maintainable." (Leon van Rooijen)
"This communication is to let you know that for our specific purposes,
CHARVA has proven to be extremely suitable. It is working well and the
system using it will be going into production shortly.
Over a number of years, Fujitsu in Australia
has developed and maintained a Train Management System for Pacific National
The Train Management System
is supported by Fujitsu's office in Adelaide South Australia (contact 61 8
8305 8500) and manages Pacific National's locomotive, wagon, freight and
container movements around Australia.
Pacific National is the largest private rail freight operator in Australia
with annual operating revenue of more than $1 billion dollars (AUD).
Pacific National operates nationally and has around 3100 staff, 1000
locomotives, 10200 wagons, and 85 sites.
Recently Pacific National requested that Fujitsu add a Container Handling
Module to track container movements for containers in Pacific National's
possession. A component of that module is used by crane and forklift
operators (placing containers on trucks, wagons, etc) who have wireless
networked computer systems in their cabins.
These systems (486's running DOS 6.22) connect to a central server and run
a "CHARVA" based application which interfaces to the main system giving the
operators interactive communications, work orders, status updates, etc.
The actual "charva" application system is quite complex and has real time
screen updates via event callbacks and other advanced java usage. The 486
systems in the cabins have a screen display of only 40 characters wide by 8
lines so we have had quite a challenge getting things to fit (we had to
remove all line drawing capabilities, etc to save screen space).
Thank you for providing such an excellent package.

Craig O'Shannessy has developed
a Charva-based application for
UndercoverWear that runs on
ruggedized mobile computers mounted on forklift trucks. Each mobile
computer has an 8-row by 40-column screen and a pass-thru printer, and
Telnets using a radio link into a Linux box. The back-end is an EJB-based
application running on jBoss. Here's a recent
message from Craig:
"I've been using Charva commercially for about 2 years, with no problems
at all. I'm only using it on about 7 terminals, but they are going hell for leather
(vehicle RF terminals mounted on trolleys with scanners and printers), all together
I found your library VERY useful and well-written; in my application
(Faktotum3, a Cocoon-based application for invoice management) it is the
framework for my setup procedure. Thanks a lot!
I tried your library on Solaris 9 SPARC, Solaris 10 x86, Linux x86 and Mac OS
X Panther: it worked well, but for Mac OS X Panther I had to give the
"-Djava.library.path" switch to the JVM.

"I have been using charva for the past one year and it has turned out to be
the most ideal solution for my project which has an expansive module that
deals with handheld terminals. The TUI for handhelds was done using charva
with least of changes made to the actual charva framework. The product
has gone live in two customer sites and the performance so far has been
extremely good. I would like to thank you for the support during this
period. I would be happy to serve as a reference to anyone who has doubts
on the usability or dependability of charva."
Thanks once again
The result of testing of ASBT Software Company:
- Hardware: HP NetServer TC4100 P3 1.26 Ghz 256mb U160 (it's a very poor server).
- OS: SuSe Linux 9.
87 simultaneous users on a single server work without problem in real time.
The application is for paying communal services and I want to change all web technology on this one because it's
low bandwidth in Uzbekistan.
Thank You a lot!
Adrian Papari used Charva in his
GILoT project (Generic
Interpretative Log Tail).
