in dropdown problem

Hello Ranchers

I'm doing a program in jsp-oracle.. and when a jsp page is called the combo box in that page has to display a particular field in the database

the problem comes next
the combobox now have the employee ids (100 nos)
so when ever i click one from the combo
i want to get the emp name, and details in the text box..

for that can i call another query for that
or can i do that using java scripts

please help me ranchers

can you elaborate your question

hello!!
my question is this
i'm doing a project in jsp - oracle using the webserver tomcat.. ok

now the module i'm developing is salary details of the employees
for that in the page there is one combo box and three text boxes

combo box referes to employee id
text box1 refers to employee name
text box2 refers to employee details
text box3 refers to salary

in the combo box i've connected it to the database oracle
so when the page is loading it will shows all the 100 employee id
when we select any one from the combobox the details corresponding to the employee number should display in the text boxes

for egs:
if i select the employee number : 45
name = Aravind Prasad
details = Project student
salary = 5000

like wise

for getting the values in the combo box i use the jdbc connection
the query is like this
select * from table1;
while (rs.next())
{ String name = rs.getString(1);
%>
<option><%=namme%></option>
<%
}
but for onChange() function in combo box i've to use java scripts

so again in inside the function
do i want to write the whole jdbc code..

please help me ranchers

You should not do all the DB stuff in the JSP view.
Do it in a module controlled by a servlet.
Set all the necessary information into a bean, and use it in the jsp view.
