I'm trying to load the "openNLP" library in RStudio and I'm getting the following error. I get a similar error when I try to install the "RWeka" package.
How do I troubleshoot this?
library(openNLP)
Error : .onLoad failed in loadNamespace() for 'openNLPdata', details:
call: .jinit()
error: JNI_GetCreatedJavaVMs returned -1
Error: package or namespace load failed for ‘openNLP’
JavaVM: requested Java version ((null)) not available. Using Java at "" instead.
JavaVM: Failed to load JVM: /bundle/Libraries/libserver.dylib
JavaVM FATAL: Failed to load the jvm library.
Found a solution to my issue. This is what worked for me. Please see below:
Launch R at the command line (to test the solution):
sudo R CMD javareconf
export LD_LIBRARY_PATH=$JAVA_LD_LIBRARY_PATH
LD_LIBRARY_PATH=$(/usr/libexec/java_home)/jre/lib/server: open -a RStudio
Now within RStudio:
install.packages("rJava", type = "source")
install.packages("openNLP")
require(rJava)
require(openNLP)
To launch RStudio from finder (El Capitan), you have to link libjvm.dylib to /usr/lib.
sudo ln -s $(/usr/libexec/java_home)/jre/lib/server/libjvm.dylib /usr/local/lib

I got a problem when I called 'XLConnect' library in R.
Loading required package: XLConnectJars JavaVM: requested Java version
((null)) not available. Using Java at "" instead. JavaVM: Failed to
load JVM: /bundle/Libraries/libserver.dylib JavaVM FATAL: Failed to
load the jvm library. Error : .onLoad failed in loadNamespace() for
'XLConnectJars', details: call: .jinit() error:

Error: package ‘XLConnectJars’ could not be loaded
This error happened after I installed XLConnect and wrote library(XLconnect).
I googled this problem but there are no proper solution in my case.
I have already installed Java 8 and checked java location in terminal.
I run R in mac OS X (10.10.5)
Thank you for your help.
I solve the problem thanks to http://www.r-bloggers.com/getting-r-and-java-1-8-to-work-together-on-osx/
I just downloaded xlsx package in R, but I just can't use the library. (On Mac)

What am I doing wrong?
Make sure you have installed the dependencies:
xlsxjars
rJava
And, of course, if that does not work, verify you have the Java JDK installed in your mac: javac -version If not, just install it from here: https://java.com/en/download/faq/java_mac.xml
