please help me

Hi
Im krishnamallik
Iam doing webdesigning project ,
My problem is

I hav three jsp pages
Now i hav to access all the parameters from page1,page2 in page3

and in the second jsp page i hav a listbox and by selecting an item from the listbox i will pass that variable to the same page url and then i can access it and store it in a jsp scriplet ie say i stored the variable in String s.
now by doing this all the parameters from the page 1 are becoming null

ie
while passing the selected item from listbox all my data ie available in the url is removed
iam using a javascript event
ie

window.href.location(“page2.jsp?selecteditem=”+se);

becoz of this all the pervious parameters that are in the url are removed
so i am getting null values
is there any other way to access the item form list box and storing the value i the jsp variable ?

I fancy this way becoz depending on the item selectedi form the list box
i hav to retreve relevant data from database.

please help me
