I want to create a combo box in jsp that contains values fetched from my database.
Here's the code that I've written,but it returns a blank combo box,even though there are values in the database.
<select>
<%
Connection con=null;
ResultSet rs=null;
try
{
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
con=DriverManager.getConnection("jdbc:odbc:db","root","root");
HttpSession ss=request.getSession();
String uid=(String)ss.getAttribute("id");
PreparedStatement pst=con.prepareStatement("select name from emp where uid=?");
pst.setString(1,uid);
rs=pst.executeQuery();
while(rs.next())
{
out.print(rs.getString("name"));
%>
</select>
<%
}
}catch(Exception e)
{ out.print(e);
}
%>
