Getting JRI/rJava to work

not think the notes about a deprecated API are a problem. But

JRI and XTS library

I am using JRI with the XTS library.

Trying to create R dataframe with JRI
Hi all,
I am writing here because the JRI mailing list seems abandoned...
maybe some of you guys know an answer or has a pointer into the right
direction.
I am quite confused by the jars that exist between rServe, JRI and
rJava. What I want to do is simply using a local R instance from Java
and I thought (and still think) JRI is the way forward. I did the
