I have this code

<c:set var="salary" scope="session" value='<%= session.getAttribute( "theName" ) %>' /> <c:if test="${salary == 121}"> <a href="create-news-item">Create News Item</a> <br /> </c:if>

The page must display the create news item link but it doesnt. When I tried to change the value of the salary to 121 it shows the page. Whats wrong here?

Can you explain me what these code does?Is it the same with the asp.net that restricts the folder content for the specified user?

I have a code that use dropdown list in my jsp page

here's the code

<tr> <td width="27"> </td> <td width="164"><label class="textFont">Organization Type</label> </td> <td width="168"><select name="OrgType" class="txtbox" tabindex="1"> <option value="1">Please choose...</option> <% Iterator it2 = Org_Items2.iterator(); while (it2.hasNext()) { OrganizationItems orgItem2 = (OrganizationItems) it2.next(); //EMSItems newsItem4 = new EMSItems(); %> <option value=<%=orgItem2.getOrgTypeId()%>><%=orgItem2.getOrgTypeName()%></option> <% } %> </select></td> <td width="120"> <% if (errors.containsKey("OrgType")) { out.println("<span class=\"warning\">" + errors.get("OrgType") + "</span>"); } %> </td> <td width="30"> </td> </tr>

then I use the following in the header of the page

<%@ page import="java.util.Iterator"%> <%@ page import="data_registration_items.OrganizationItems"%> <jsp:useBean id="Org_Items2" scope="request" type="java.util.List" /> <jsp:useBean id="errors" scope="request" type="java.util.Map" class="java.util.HashMap" />

I tried to verify that the dropdown control does not allow to pass the value of the "Please Select..." by the code

String OrgType = req.getParameter("OrgType"); if ("1".equals(OrgType)) { errors.put("OrgType", "Required"); } else if(req.getParameter("OrgType") != null && !"".equals(req.getParameter("OrgType"))) { long OrgTypeId = Integer.parseInt(req.getParameter("OrgType")); emsItem.setOrgTypeId(OrgTypeId); }

but still I cannot get it...How can I properly handle this situation?
