I am new to web development. I have an external JavaScript file which has a function to show
a prompt with error details. I need to pass the error message to the function. I have written contoller in servlet.
How to call the function of that JavaScript file from my servlet.
It is not possible to call a java script function from a servlet. Rather, you can print javascript code using
response.getOutputStream().println("[javascript code]");into the browser and then the javascript function will be executed in the browser.
