I was trying an example of the example of above book on page 190(example is given as newservlet.jpeg(please open it with any text editor as it is not a valid .jpeg file)).The first time when the
servlet is run though the output is 22 and 42,but as the context attributes arent
thread safe,the second time when I run the servlet the result should have been affected(as pointed out in the book),but i see the same output.Why do i see the same output each time?
