Hi,
Take a look at the rJava package. It includes JRI that lets you call R
from Java. From the README:
This package contains code that is necessary to run
R as a single thread of a Java application. It provides
callback that make it possible to run R in REPL mode
thus giving the Java application full access to the
console.
Currently the API is very, very low-level, comparable
to the C level interface to R. Convenience methods for
mid to high-level are planned, but not implemented yet.
Good luck,
Lars

Hello,
I am interesting in using R from a web application, for basic statistics and
plots. The server is Java-based (tomcat).
The simplest solution is a system call that generates the text or the image,
then the servlet forwards the output. This can be done from any language,
but it is quite inelegant and slow for the initialization time.
Is there any package or approach for accessing R from a Java servlet you can
suggest?
Thanks in advance for any suggestion.
Regards,
