How to get request object in Servlet If I am not using any HTML or JSP page.So in this case How doGet() will understand what is request coming from browser.

Hello Steve,

you can eve try out this because i am not allowed to out the code , so if you can ,try out this . one program having field count which auto increment when say, you click a button (assuming that you got scenario .. like a screen which is having a textfield dispalys current count value and a button . On actionEvent of this button increments the count value.) so if you and one more person trying to use 'same program at same time' ,then both of you will get same number, which is wrong. it should not allow same number .

so i hope you got exact situation.....

thanks

hello ,

what i exactly want to say is, if i have an application which have one field which is autoincremented, like as n when user add the record, the number will get incremented automatically.. now my problem is when 2 or more user trying to add record , from different machin. all of them are getting same number by saving the record. so the next process goes on toss.. i want something which will restrict record from saving when such condition occure. synchronization is not work in this case. so what could be its solution. whether a kind of class lock will be my solution. or something else.?

thanks in advance

Thanks guys.

why do we need an explicit call to event subpackage..like if i used any listener interface from awt.event,can i just write import statement like import java.awt.*;? .actually i tried it out already but it throws an error.so is it like that whenever i used event subpackage i need to specify it in import statement like import java.awt.event.*;.and if it is so,why?

Jim
Thanks for suggesting me a way,but i have already tried out that one....

Hello Peter,
I do not know how to convinced you,but i am genuinely interested to know each and every thing related to java ,even if it basic thing or a so called "tricky" thing..."to be the best in any thing you should know everything "

as well as one more thing i want to ask is can we set heap size in java,i was trying to do that using command prompt as"java maxheap <size>",i have tried a lot of option like setmaxheap,heapmax and stuff.. but i was not successful. so now i hope you will definitely going to help me.
