          over 9 years ago Hi Lalit, I was in the same condition few days back, the solution I find for the problem is that I downloaded the new jar files from http://www.seleniumhq.org/download/ , next thing you have to do is to remove old jar files and add new jar files. Just follow these easy steps to add new jar files 1. Right click on the "My project" you are working on. 2. Go to "Build-Path" -> Click on "configure Build Path". 3. A window will open "Properties for My Project", Now Click on Libraries Tab and select all the files except "JRE System Library", click on "Remove". 4. Now click on "Add External JARs...", Select All the files from you have downloaded from http://www.seleniumhq.org/download/ , Click on "Open". 5. Now "Run your Scripts". I hope you will not face any Problem

          over 9 years ago You need to check the jar files for that. Download new selenium jar and upload it. http://www.seleniumhq.org/download/

          about 10 years ago Hi Lalit, Although this is not clear from your question which selenium component you are using for your test cases but still you can try again after downgrading your browser version which is compatible with selenium version.
