- Install rJava & JRI from source or binaries.(Don't install through R's command line prompt -- it will get you a version that's too old). You'll need rJava version 0.8-0 (or any version that has JRI version 0.5-1 -- the JRI versions are not the same as the rJava versions).
- If you downloaded a source package (any unix system will be from source) build JRI.
- Look up the installation path that JRI went into. (TODO Can we improve these directions?)
- Edit your tomcat launch file.
If you're using eclispe (Java programmers only) continue here, remembering that JRI installation path.
If you're installing the normal way using Apache Tomcat, remember the JRI installation path and continue here.Installation Directions
