[java] how to fix Cannot call sendRedirect() after the response has been committed?

The root cause of IllegalStateException exception is a java servlet is attempting to write to the output stream (response) after the response has been committed.

It is always better to ensure that no content is added to the response after the forward or redirect is done to avoid IllegalStateException. It can be done by including a ‘return’ statement immediately next to the forward or redirect statement.
