Eclipse 3.5 / Statet / R Console not working on Ubuntu linux

Question

Hi,

I had Eclipse 3.4 working nicely with the R Console over rJava. I want to get Sweave working in Eclipse, but need Eclipse 3.5 / statet 0.8 to do it.

When I try to start the rJava Console the JVM starts, but no feedback comes back to the console in Eclipse.

JVM process below - any help gratefully received.

Thanks, Dave

I think I fixed it.

I found the Eclipse option which writes stderr to a console, and basically got the trace this guy got, talking about

SEVERE: Unsupported JRI version (API found: 108, required: 109)

http://lists.r-forge.r-project.org/pipermail/statet-user/2009-August/000200.html

Basically my rJava installation was out of date. The ubuntu repo gives 0.6.3, but installing the latest 0.8.1 from cran fixed it.
