How to select value from list with multiple selections ?

Question

HI,
i have a list with multiple selections where i show email address retrieved from database.
what i want to do is to send the selected email address to the invoiceedit.jsp.
please look at the following code which gives you the better idea.
<td class='smalltext'><select name="email" size="3" multiple="multiple">
   <% 
   Connection conn = null;
   Statement stmt = null;
   Statement stmt_contactperson = null;
   Statement stmt_address = null;
   try{
      conn = getREConnection();
       stmt = conn.createStatement();
   ResultSet rs = null;
   rs = stmt.executeQuery("SELECT PROPERTYID, VALUE FROM PROPERTIES WHERE ENTITYID="+ g_strGroupID+" AND NAME = 'invoice_default_email'");
   int numofrows = 0;
   while(rs.next())
           %>
   <option value="<%= rs.getString("VALUE") %>" selected="selected"> <%= rs.getString("VALUE")  %> </option>
    <%
       }//end of while
      %>
     </select>
    <a href="invoiceedit.jsp?entityid=<%=g_strGroupID%>&add=1"><font color="#000000">Add</font></a>
     <a href="invoiceedit.jsp?entityid=<%=g_strGroupID%>&email_to="><font color="#000000"> Edit</font></a> </td>thanks

Answer 1

Use a form button instead of a link so that you can send it as a request parameter to the server. In the server side just use HttpServletRequest#getParameterValues() to obtain all values for the given parameter name. If you really need a link rather than a button, then use Javascript to submit the form on click of the link.
That said, your design is bad. Java code belongs in Java classes, not in JSP files. Database access logic belongs in a DAO class. Business and controlling logic belongs in a Servlet class. Only presentation logic belongs in the JSP file. Avoid scriptlets as much as possible and use JSP EL and/or JSTL instead.
