JSP - capture the value from the dropdown list
I got the JSP page which calls itself where the Search button is clicked.
I don't know how to capture the value from the drop down list and pass back the value to the page itself.
For example, if the user select 'Perth', from the downdown list, it then triggers off the search fuction (all work - ejb function) and return all records with the location, Perth.
But in the dropdown list, i dont know how to place the selected value.
Because whenever the page calls itself, it resets the dropdown list.
==========================
<td width="50" align="left" >
<select name="pickupLocation">
<% for (int j = 0;j < Constants.SR_STATUS.length
String value = Constants.SR_STATUS[j];
%>
<option value="<%=value%>"><%=valu
<% } %>
</select>
</td>

ooops.. the else part needs to take the "selected" out of it
<% }else {%>
<option value="<%=value%>" ><%=value%></option>
<%}} %>
<% }else {%>
<option value="<%=value%>" ><%=value%></option>
<%}} %>

I got compilation error
<option value="<%=value%>" <%= value.equals(request.getPa
<option value="<%=value%>" <%= value.equals(request.getPa

You're missing an ) there
value.equals ( request.getParameter ( "pickupLocation" ) )
You're missing an ) there
value.equals ( request.getParameter ( "pickupLocation" ) )
(so was I)
there is a missing parentheses in it...
Ooops..
Late again..:-)
