In spite of any software could be hacked, the objective must
not be to avoid the piracy at any price, but rather develop
useful programs without annoying anti-piracy systems.
This fact despite of being so logic and simple sometimes is
forgotten. In our case, a long time ago we started developing
Smart Positioning Architect, an RTLS desktop application. In
that moment the future of that application was not clear and we
decided to develop under Java and Eclipse Rich Client Platform
(RCP) without having in mind the possibility of licensing
The Smart Positioning Architect was designed as a tool for
private use to design, configure and calibrate the environment
for Wi-Fi real time location systems. This tool in addition
provides a real time and on demand visualization of an
enterprise asset (objects, people, mobile devices) location.
Using this tool an enterprise can have a global visibility of
what happens in it and improve its workflow, specially the key
processes where the enterprise needs to maintain positioning an
Some years later we realized that we had a very powerful
software, so we decided to launch it as a commercial software.
Unfortunately, as anybody knows, any Java application
(including Eclipse RCP) could be easily decompiled, revealing
the source code of the system.
We tried to securize the application with a lot of
anti-piracy techniques: fuzzing the jar files (but it only
difficult to understand the source code), hardware dependant
techniques (not secure at all and not always possible), etc. We
wasted valuable time and money and we did not solve the
problem, moreover some of these techniques were annoying for
customers or should be customized with the consequent increase
in the distribution costs.
In that moment we assume that this situation was untenable,
so we decide to search an alternative. If we did not find a
solution we decided to redevelop the system from zero,
converting it into a Web application, a task that would be too
expensive. Fortunately, when we were searching for a new
solution, we found Excelsior JET which is easy-to-use and have
powerful features: creates executables and dynamic libraries,
maximizes performance, protects Eclipse RCP applications from
decompilers, encrypts program data and resources, built-in
advanced installer feature, etc. In summary, Excelsior JET
guarantees a powerful securization including a simple process
to create a custom installer to distribute your software with
As a result, we can finally distribute our RCP-based system
without the fear of somebody is going to decompile it.
Moreover, we can send time limited demos of our system to
anybody who demand it, enabling an increase of our potential
customer base and benefits.
Simply amazing and only possible with Excelsior JET.
