12. Productivity without compromise
●
Roo's innovative approach is free of any
compromises:
–
Program in Java!
–
Full IDE support (with features like code assist,
refactoring and debugging)
–
No runtime portion, which means easier adoption in
enterprise with approval requirements
–
Excellent runtime performance, as there's no runtime
memory usage, deployment footprint, control flow
invocation time etc

13. Productivity without compromise (2)
●
●
●
●
Lower risk of bugs impacting your project, as Roo
operates entirely at development time (just like your
IDE)
No lock-in to Roo, as you can remove it from your
project in just minutes
Easy extensibility to new features thanks to OSGibased add-on extensibility
We could go on, but you get the point: Roo doesn't
make you compromise (ever) :-)

14. How it works
●
●
In a nutshell, Roo is a lightweight console shell that
you load up while developing your projects. While
the Roo shell can be used to complete timeconsuming operations in just one quick command,
most of the time you'll just ignore Roo and go off
and develop your project in your IDE or text editor.
As you go about editing code in your normal way,
Roo keeps an eye on your project files and
automatically modifies them in response to your
actions. Depending on the Roo add-ons you have
running, Roo can help you with different types of
files.

15. How to install Roo
●
If you downloaded the standalone Spring Roo,
simply unzip it to a location of your choice. Then:
–
Windows users: add %ROO_HOME%bin to your
path
–
*nix users: create a symbolic link to
$ROO_HOME/bin/roo.sh (eg sudo ln -s ~/springroo-1.x.x/bin/roo.sh /usr/bin/roo)
