problem using rJava with parallel::mclapply
Dear all,
I got an issue trying to parse excel files in parallel using XLConnect, the
process hangs forever.
Martin Studer, the maintainer of XLConnect kindly investigated the issue,
identified rJava as a possible cause of the problem:
This does not work (hangs):
library(parallel)
require(rJava)
.jinit()

RJava question(class not found with rJava's vm, though found with alternate vm)
Not sure if this the right place, but I can't seem to subscribe to the rJava
mailing list. Sorry for the noise.
I have a jar file in the CLASSPATH variable. On running .jinit and checking
.jclassPath, i can see the jar file containing the class. Yet when trying to
instantaite the class, i get a class not found error.
Now If if, create my own vm (see below), and then run .jinit (which will

rJava and matrices
Hi list,
I'm wanting to use a matrix as input to some java code, but I seem to be
unable to do this (See code below). When searching online for a solution I
found that rJava 0.5-2 (the version under development not yet in CRAN) is
adding "direct support for raw vectors as method parameters". Is this
related?
I also tried to use .jarray / .jcast in various combinations to no avail.

rJava Broken on Linux + R 3.4
Hi Dirk,
It was unclear to me to which extent it is a
kernel/security patch vs (r)Java issue.
In any case, this is really problematic for me as it prevents me de
facto from running some key R packages for my daily work.
I'll post again if I see some solution (other than downgrading the
kernel) somewhere.
Meanwhile, any suggestions for a fix is welcome.
Cheers

ClassNotFoundException when running distributed job using rJava package
Hi,
I have a MapReduce Java code, which I am calling from R using rJava. I have
prepared the R package and tested that successfully. But when I deployed
the package in a cluster and executed it, I am getting
ClassNotFoundException. If I run the same job directly without integrating
with R, it runs perfectly.
Here is my R code:
