RAMADDA is available on GitHub. With Java and ANT installed run the following:

git clone https://github.com/geodesystems/ramadda.git
cd ramadda
ant

The build files above will be in the dist sub-directory

To run quickly on your local machine do:

sh dist/ramaddaserver/ramadda.sh

This will create a RAMADDA home directory at ~/.ramadda. To change this do:

sh dist/ramaddaserver/ramadda.sh -Dramadda_home=/some/other/directory

RAMADDA will be available at http://localhost:8080/repository
