   I have a data table with thousands of data. i have a search functionality. if I search a term, the row which contains the term has to be highlighted and scroll position should be on the row. it is working fine. but it takes too much of time to position the scrollbar. this leads to performance issue. can anyone help to fix this.

currently i have set style class to the match row. searching for the style class and calculating the position and setting it with jQuery.

is there any other way?
thanks in advance.

I am working in a jsp web application.
in that i am

storing the login time and logout time in database.

its working fine.....

the problem is when the session timeout (ends automatically) i could not get the logout time.

i think i need to call a function before the session timeout.

is it correct? if so how to solve this?

or any other solution?
hi Ulf Dittmer,

I could not understand your reply.

see this is my problem..... is my systems default ip (localhost);

100.987.0.28 is my TCP/IP ip (system is connected in LAN).

If I call 100.987.0.28:8080 from other system in LAN my application works fine.

if I call then it is not working.

in host file I just configured

should i add 100.987.0.28 also in host file?
