Hi Folks,
Im developing a jsp page where I set the value obtained from a dropdown to insert into a database.
Im using java script to fetch the value of the dropdown in the jsp , and then use the value for processing in the servlet. Im able to pass the value of the dropdown successfully here .
Its something like this..


However , when I click on a value in the dropdown the page submits as expected and the form is submitted to the Servlet , which processes the request,but when the page reloads after submission the dropdown value is lost and is set to the default "--Select--" value , any ideas where i could be going wrong ?

Dear Vic Hood,
Once the page is submited, the response is commited. When the page reloads after submission the request is new request hence the value whichever you set before submit will not be available. If you need to maintain the value you had assigned to the 'd-down' drop down you need to set the value to the 'd-down' attribute in the servlet and get the value form the request attribute in jsp and set that value to the 'd-down'

You need to put the selected attribute on the <option> that you wish to be selected. Otherwise it defaults to the first choice.
