hai , iam new to jsp . I Encounterd a problem
My problem is i have one form,where i retrive the values in to one combox box from database.User can select from the combobox,based on his selection, i have to retrieve data from database and has to display in the textbox in the same form.The previous values in the form should be retained
Use Struts and JSP to do that.
Send the value of the combo box inside the struts. Do your work with the database (use EJB's or direct connection) then remeber to send as attributes or parameters back the value of the text field and of the combo box. With a little bit of JSP you should be able to set the selected element in the combo box, and the text inside the text field.

Am I mistaken, or wouldn't that require a page refresh? Which I thought the OP didn't want. Sorry, I don't know Struts, but so far it sounds to me like something a mere servlet/JSP combo could do as well.
Yes in how I said it you would definitly need a page refresh! (Sorry I did not get that point from the OP ... tought he just wanted to keep the combo box value :$
Once i read about doing callbacks if that is what the user wants. However I only did them in ASP.net and not JSP. So I don't know much else about the subject!
