1.Why does only one copy of a servlet object get created? What happens if you want to remove an old servlet object currently running but do not want to stop the entire servlet engine? 2.How does one servlet object deal with interactions from many browser? (e.g. if your servlet ran an email site, how can it keep track of hundreds of users logging in, reading their mail, etc.)

Design a timer circuit using VHDL which has the following: input : start_timer(ST) output: long_time(LT) short_time(ST) when the timer is triggered by the ST(either 0 or 1) signal the timer should generate two timing signals accordingly.While the long time is going ON the other should be OFF and vice versa.

I have a file which contains so many lines and variable number of lines are treated as a record. For example *first ooooo xxxxx ttttt mmmm vvvvvvv *end uuu bbbb *first kkkkvvvvvv nnnn mmmmm kkkkk fffff gggg ffff kkkk lllll *end. Here the lines from *first to *end are treated as a record. The number of lines between *first and *end is not same for all the records. Suppose there are 100 records (or number of records are not predefined)like the format given in the above example. Now the entire file needs to split into two files, first having 40 and remaining in the second file. Can we split using sort utility? If possible then what is the sort card?
