inconsistent behavior in RSelenium
library(RCurl)library(RJSONIO)library(XML)# running seleniumsystem("java -jar selenium-server-standalone-2.44.0.jar")I faced same issue and try to run above code. Finally know that there only support 1.7 but not 1.8 as time being. You might try to download jre7 and jdk7.
I faced the same error in Mac, but I noticed that due to security settings the system does not let me to run the file with that piece of code. I downloaded the selenium standalone file and using control key I single-clicked the file and then from the menu I chose the open. Then the problem get solved.
