Your jsp form action id when u press submit it will call
the action which is in html form action(some jsp,or
servlet) that jsp will able to get employee id throuh
req.getparameter('employee_id'); and then tht JSP use bean
class for connection to DB using JDBC and then it will
return result to the calling jsp and tht jsp will print
responce (employee details) and tht generated out put will
be sent to the client.
