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:
JNI_GetCreatedJavaVMs returned -1
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 have tried to call the library xlsx, since I want to save data in multiple-sheets excel files, but I got a Java-related error. Even when I run library(rJava) I have this error code:
Error: package or namespace load failed for ‘rJava’:
.onLoad failed in loadNamespace() for 'rJava', details:
call: inDL(x, as.logical(local), as.logical(now), ...)
error: unable to load shared object 'C:/Users/me/Documents/R/win-library/4.0/rJava/libs/x64/rJava.dll':
LoadLibrary failure: The specified module could not be found.
The solutions I have found online are quite old and none helped to solve the issue: I have tried to reinstall Java 64 bit on my OS (Windows 10-64bit), and the package rJava, I have tried to set Java home with Sys.setenv(JAVA_HOME="C:\Program Files\Java\jre1.8.0_271\") without success. I use R 64 bit.
Do you have any suggestions?
Finally, the solution reported here worked for me. The most important thing is to download the offline version of Java
I am trying to download the xlsx package in R but get the following error message:
Error: package or namespace load failed for 'xlsx':
.onLoad failed in loadNamespace() for 'rJava', details:
call: fun(libname, pkgname)
error: No CurrentVersion entry in Software/JavaSoft registry! Try re-installing Java and make sure R and Java have matching architectures.

I have also tried to download rjava, but get this error message:
ERROR*> JavaSoft\{JRE|JDK} can't open registry keys.
ERROR: cannot find Java Development Kit.
Please set JAVA_HOME to specify its location manually
ERROR: configuration failed for package 'rJava'

I have reinstalled Java to my computer, with the same architecture s my computer and R (64-bit), which most of the help online says that I should try out. Have anyone experienced the same problem?
Hi and thanks in advance,
Don't know why but I get the following error message when trying to load a csv file in my RStudio desktop version that I have installed in my MAC:
Error: package or namespace load failed for 'rJava':
.onLoad failed in loadNamespace() for 'rJava', details:
call: dyn.load(file, DLLpath = DLLpath, ...)
error: unable to load shared object '/Library/Frameworks/R.framework/Versions/3.4/Resources/library/rJava/libs/rJava.so':

Referenced from: /Library/Frameworks/R.framework/Versions/3.4/Resources/library/rJava/libs/rJava.so
Reason: image not found
Could you please help me? I have tried downloading the latest version of Java, but does not work.
Thanks!
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
I am receiving this error when I use packages XLConnect and rJava.
Loading required package: XLConnectJars

I have not seen this specific error in any threads here on in this community. Though I do believe the issue to be related to some other threads.
I have downloaded 64-bit java, and have tried to fix the path to java with:
Sys.setenv(JAVA_HOME='C:\Program Files\\Java\\jre1.8.0_65\\bin\\client\\jvm.dll')
