I received an exception after trying to setup a connection to selenium-server-standalone by using remoteWebDriver in an application test written in Java.<\/p>\n
The issue is related the usage of remoteWebDriver starting selenium-server-standalone (with Xvfb) by using maven (because by running manually by a different session Xvfb and then selenium-server stand alone the application test is working). The environment is composed by RH Linux R4.1.x , Selenium 2.1, firefox 3.6. Both selenium-server-standalone and application test are executed on the same machine (Virtual Machine).<\/p>\n
As previously said, the application test run successfully connecting to the instance of selenium-server-standalone-2.21.0 if this instance is started by a separate PUTTY session (separate from the one used for starting the application test) with the following commands:<\/p>\n
#Xvfb :20 &\n#export DISPLAY=:20\n#Java -Dwebdriver.firefox.firefox=\"\/opt\/firefox\/firefox\" -jar selenium-server-standalone-2-.21.0.jar -port 4441.\n<\/code><\/pre>\nThe application test code for connecting to selenium-server-standalone is the following :<\/p>\n
DesiredCapabilities capability = DesiredCapabilities.firefox();\ncapability.setPlatform(Platform.LINUX);\nWebDriver driver = new RemoteWebDriver (new URL(\"http:\/\/127.0.0.1:14444\/wd\/hub\"),capability);\ndriver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);\n<\/code><\/pre>\nNow trying to use maven for starting also xvfb and selenium-server-stand alone before starting the application test I get the following error (then within same putty session):<\/p>\n
