Based on the provided code, it seems that the issue lies in the logic of the "mesActionServlet" class. In the "service" method, the "path" variable is not being assigned a value, thus it remains null. As a result, the condition if (path.equals("addemp")) will throw a NullPointerException and the code inside the if block will not be executed.

To fix this issue, you need to assign a value to the "path" variable. You can modify the code as follows:

String path = requestURI.substring(requestURI.lastIndexOf('/') + 1, requestURI.lastIndexOf('.'));

This will extract the desired path from the request URI and assign it to the "path" variable
