Answer 1

We cannot help you without seeing your "some code".

You should be able to use System.in class which provides you access to STDIN without any issues. Something like:

def userInput = System.in.withReader { reader ->
    OUT.println 'Please enter test parameter'
    reader.readLine()
}

OUT.println('You have entered: ' + userInput)

vars.put('userInput', userInput)

Be informed that due to multithreaded nature you wil need to provide the input for each thread (virtual user) so the suitable location for the JSR223 Sampler would be setUp Thread Group with 1 user and iteration.
