Even i am facing the same issue, some one please help on this

[Chirag_Singh]

When I use "selenium-server-standalone-2.53.0.jar" file then face the same issue but when I use "selenium-server-standalone-2.48.2.jar" file then IT IS WORKING FINE.

I think selenium guys remove any method in the selenium-server-standalone-2.53.0 version. I also tried by adding "commons-lang-2.6.jar" file into my framework but facing the same below issue.

Please provide some help to resolve this issue in the latest selenium version jar file.

[raghutej]

HI Chirag ,

Thanks very much for the reply .

As mentioned , the selenium server 2.48.2 i have included and verified the test . Now the error is resolved .
It seems like more packages included in the "2.48.2" when compared to the latest selenium version .

Thank you very much for the support.

Hi All,

Could you please suggest us regarding this issue.

Thanks,

I think selenium guys remove any method in the selenium-server-standalone-2.53.0 version.

If you think this is so, why not check? It's open source. I don't know what methods you might be looking for, so here's a link:

hi,
I found this solution here

Failed to switch between android apps during appium automation

I had the same problem too. This is due to the problem of StringUtils. I downloaded Apache Commons Lang plugin and problem was solved.
The download can be found here: http://commons.apache.org/proper/commons-lang/download_lang.cgi
After downloading, add commons-lang3-3.5.jar to your external libraries in your IDE.

[Dheeraj_Shandilya]

Thanks Arpit

I also downloaded Commons-lang3.7 from url http://commons.apache.org/proper/commons-lang/download_lang.cgi .
Added this to project folder and run the program. It works fine. I was using Selenium 3.11 jar files

[Sumeet_Panjabi]

Add the CommonsLang3 jar to your project
https://mvnrepository.com/artifact/org.apache.commons/commons-lang3

[Nilanjan_Mondal]

Similar issue I also faced. But after adding latest selenium jar(selenium-java-3.14.0) along with junit, hamcrest-core and commons-lang JAR files issues got resolved.

[Cal_Mobtest]

Thanks for this important info, your solution is working
