unable to source a .R file using RJava
I am unable to source a ".R" file using RJava. I tried a couple of different tests:
1) using java and the evaluation method core dumps
2) using ./RJava --example --gui-none to invoke source core dumps.
3) The line of R works if I go directly thru R and not RJava.
Version info and code are below. Any help would be appreciated.

SJava help
Hi,
I installed SJava 0.66-1 on my linux RH 7.2 machine. I am using R-1.7.1.
I set LD_LIBRARY_PATH up then called library(SJava) and it was fine. But
when I called .JavaInit(), I got weird error that states it could not
find java/lang/Hashtable. The session is below and shows my java
configuration. I am using j2sdk1.4.2_01 from Sun.
Thank you very much.

SJava embedded in R
Hi,
Here's some suggestions for troubleshooting the
