How to solve java.lang.NoClassDefFoundError?

Question

I\'ve tried both the example in Oracle\'s Java Tutorials. They both compile fine, but at run-time, both come up with this error:

Exception in thread \"main\"         


        

Answer 1

For my project, what solved the issue was that Chrome browser and chromedriver were not compatibles. I had a very old version of the driver that could not even open the browser. I just downloaded the latest version of both and problem solved. How did I discovered the issue? Because I ran my project using the Selenium native firefox driver with an old version of FF inculded with my application, I realized then that the problem was incompatibility of between browser and driver.

Hope this can help anyone with a similiar issue as mine, that generated this same Error Message.
