Hi, Henrik,

Thank you very much for replying.

I actually have the JAVA_HOME environment variable set in a linux shell
script .bash_profile which set up all of my development environment
before I install this SJava package and it points to the current java
cdk I am using. So it is weird that R could not find the common java
libraries. Do you think I need to use .Renviron instead of
.bash_profile?
