I finally got it running (sorta) on my RH7.1. I would make sure you
have the latest package from Omegahat first. Then, I believe
the most likely culprit is the LD_LIBRARY_PATH env variable.
Mine includes the following (my bash profile).
<p>You can replace the java directories with the jdk you are using.
Also make sure that error messages aren't pointing you to a '.so' (in the
libs directory of SJava) that you don't have. I had to rename one
of them in an earlier version of the SJava package.
<p>Even with this, I am only able to run an example after I run java at
least once. I would open the BASH shell and run any java class and
then open R and be able to run the examples ( library(SJava);.JavaInit();source(....example.r);example.r();
) . This makes it a little difficult to use the package (or
at the least, inelegant) by running R in batch. I have had a lot
of difficulty creating any original code with this package. My goal
was to create some original code to allow me to run a java app that called
R. Not much luck. I put a message out some time ago but I haven't
had much luck getting responses. If anyone out there has had any
luck using this package with Redhat and IBM JDK please let me know.
Hope this helps.
<p>For the future, the omegahat help list would probably be a better place
to put this. Although I realize that list doesn't get nearly as much
feedback as this one.
