I am having the same problem and trying the solution you posted. But how can I find where I download the selenium standalone server?

RobertMyles · 2015-09-08T18:46:55Z

Hi lli48, if you search your computer for "selenium-server-standalone.jar" you should find it. I manually clicked on this, and then had no more problems with the browser.

private-quant · 2015-09-13T21:51:08Z

RoberyMyles is right. It will throw an error depending on your security settings. You must approve the .jar to run from an unknown author (depending on your security settings).

englianhu · 2015-09-20T00:02:38Z

@RobertMyles, any idea to install selenium?
https://gist.github.com/textarcana/5855427#gistcomment-1577613

olivmx · 2015-12-07T04:51:23Z

Ok I was able to solve this for Mac OS 10.10.5:

First find the selenium-server-standalone.jar in your mac. and copy it to your R working directory folder

If you have already issued this command in R:

install.packages("RSelenium")

Then you should have the .jar already somewhere in your Hard Drive, but property of root user, so in order to find it I had to issue some commands in Terminal:

#change folder to top
cd /
# find file with root user. this might ask for your password:
sudo find -L . | grep selenium-server-standalone.jar

# copy the file to the getwd() folder in R; so in R issue the getwd() to see where to copy the .jar file in my case it was: 
sudo cp ./Library/Frameworks/R.framework/Versions/Current/Resources/library/RSelenium/bin/selenium-server-standalone.jar /Users/me

#change the security of the copied file (some might find this overkill permits)
cd /Users/me
sudo chmod 777 selenium*

Now find the .jar file with finder, right click on it and open it using with Jar Launcher app
If you don't have this Jar Launcher app find the java complement in apple site and install it
https://support.apple.com/en-us/HT204036

That should solve it

thomasKuilman · 2016-01-01T22:45:03Z

Hi guys,

For me the problem was that startServer() function does not work. Internally it starts the selenium-server-standalone.jar (in file.path(find.package("RSelenium"), "bin") folder) as follows:

java -jar /PATH/TO/selenium-server-standalone.jar

but for me this failed due to an outdated java version (1.6). Updating to the latest 1.7 version solved things. You could test on the command line whether the line above works; if you get an error message this is likely the reason for your error message.

Cheers,

Thomas

arvi1000 · 2016-01-04T03:40:06Z

+1 @thomasKuilman. startServer() fails for me too. It attempts to run this:

java -jar /Library/Frameworks/R.framework/Versions/3.2/Resources/library/RSelenium/bin/selenium-server-standalone.jar

and returns no message, but when I try the above from the command line I get Invalid or corrupt jarfile. (Also using java version 1.6, on Mac OS X 10.9)

@olivmx I tried to grant permission by $ sudo chmod 777 /usr/lib64/R/library/RSelenium/bin/selenium-server-standalone.jar to run the selenium-server file.

For the sake of completeness to those who know what's going on with this error.
I have the follwing code in a function:

startServer()
remDrv <- remoteDriver()
remDrv$open()

When I run it for the first time, I get same error as most people here:

[1] "Connecting to remote server"
- Undefined error in RCurl call.
- Error in queryRD(paste0(serverURL, "/session"), "POST", qdata = toJSON(serverOpts))

But if I re-run the function (without any other change), then it runs smoothly.

Hi.. I have the same issue... I searched for the the selenium-standalone-server and tried to double click on it when I get the error as "could not find the main class:" in the Java virtual machine launcher dialog box.
And it says Program will exit and nothing happens. Can anyone please help.

daattali · 2016-07-28T21:37:53Z

I'm getting the same issue too

I have two Windows 7 laptops that are very similar, same version of R. On one it works fine, on the other I get this error:

KrysD · 2016-08-02T08:34:14Z

Any solution to the Error in queryRD(paste0(serverURL, "/session"), "POST", qdata = toJSON(serverOpts)) : ?
May be tricky but by installing the latest version of java (8) the problem wa solved.

startServer() # run Selenium Server binary
$stop
function () 
{
    tools::pskill(selPID)
}
<environment: 0x0864e8c4>

$getPID
function () 
{
    return(selPID)
}
<environment: 0x0864e8c4>
remDr <- remoteDriver(browserName="firefox", port=4444) # instantiate remote driver to connect to Selenium Server
> remDr$open(silent=T) # open web browser

johndharrison · 2016-08-02T10:52:04Z

See the Selenium changelog:
https://github.com/SeleniumHQ/selenium/blob/master/java/CHANGELOG#L294
and
https://github.com/SeleniumHQ/selenium/blob/master/java/CHANGELOG#L6

So at least Java 7 is required for v >= 2.47 and now Java 8 is required for v >=3

daattali · 2016-08-02T16:26:13Z

I have java 8 and still got the error

johndharrison · 2016-08-02T17:02:13Z

There is an issue with firefox 47 and selenium 2.53.1. Firefox released 47.0.1 to fix this
https://www.mozilla.org/en-US/firefox/47.0.1/releasenotes/ however some linux distros are still showing 47.0.0 as latest version. Updating to dev version firefox 48 on ubuntu 16.04 for example worked for me.

dpost723 · 2016-08-04T15:53:45Z

My solution worked on my Mac:

I followed all instructions listed here about opening the .jar file first, which did not work by themselves (although they may be necessary for what did work).

What ended up working for me was downloading an older version of FireFox (I used version 28.0), then I turned off Firefox auto-update, and then everything started working.

I also ran:
java -jar "/LOCATION_OF_YOUR_JAR_FILE/selenium-server-standalone.jar" -Dwebdriver.firefox.bin="/Applications/Firefox"
in the terminal and kept the terminal open while running RSelenium as that helped me with error catching more than anything that showed up in the R console.

Note that there are safety concerns about downloading an older version of a browser so I only use this Firefox while using RSelenium.

johndharrison · 2016-08-04T16:15:58Z

Happy that worked for you. The java call is:

java [-options] -jar jarfile [args...]
           (to execute a jar file)

in this instance -Dwebdriver.firefox.bin="/Applications/Firefox" is being passed to the JVM. You are passing it to the selenium binary. Up until recently the binary would also parse system property flags
see SeleniumHQ/selenium#2566 . This will change in future versions and you would need to pass the options to the JVM:

java -Dwebdriver.firefox.bin="/Applications/Firefox" -jar "/LOCATION_OF_YOUR_JAR_FILE/selenium-server-standalone.jar"

The Selenium Server in theory should work as follows:

Selenium support for Firefox is the latest release, the previous release, the latest ESR release and the previous ESR release.
Currently that should be firefox 48, 47.0.1, ESR 45.3.0, ESR 38.8.0
Issues can arise if latest or previous release doesnt work with selenium binary you can try an ESR version of firefox
Can download previous firefox versions from https://ftp.mozilla.org/pub/firefox/releases/

I solved this problem. Undergrading Mozillafirefox to version 46.0.1 . It worked for me.
