Hi Nilesh
The problem is that some of jars are missing, so please check what you have done maybe remove the files. Do you get the same problem when executing other jobs? Do you execute the job in studio or out of studio?

Hi Nilesh,
Have u added any new classpath variables in the environment variables or the classpath is set?. This error may some times come because of this

Hi
Ok, can you please install a new studio into another folder? and then create a simple a job and test whether the problem still exists, if not, we will migrate all the jobs from old studio to the new one.
Note that: don't remove the old studio before you backup the projects.
Best regards
Shong
