Retaining of values in JSP while using JSTL

Dear All,
I have an application using the struts framework, wherein I am facing a problem.
Here goes the problem " In my JSP's I have multiselect, the JSTL tags works fine when all the server side validations are done. But I get a problem when an error(server side validation error) occurs, I have to retain all the multiple values selected in the Multiselect box.
Can anyone suggest me best way to retain the multiple values.
E.g. My multiselect populates 5 values
A
B
C
D
E
As a end user I select "B, C,E", and a server side validation error occurs I have to keep the values "B, C, E" selected in the above list of 5 values using JSTL
Thanking you in anticipation.
regards,
Mohan.

Dear Friend,
The control I am placing(multi select) has the data type in the form as String[],
The validation error(server side) I was talking about is: I have 5 fields in JSP, in one of the 5 fields I have a title, which is unique in the database, if the end user enters an already existing title, then all the values previously (entered, selected) for rest of the controls should be retained and an error message from application resources is populated about the title duplication.
Here I will show the entered values in text box and also the multi-selects, so using JSTL, I want a way out to retain the previously selected values....
In my JSP for the control I say <input type="select" property="propertyname" multiple="true">
of struts...
Thank you
Mohan.

Posting huge data on to JSP page using JSTL tags

Hi,
I have one application where I have to post huge data (approximately 2000 rows of data) into JSP page. I am using JSTL tags and running on Tomcat 5.
It is taking almost 20 to 25 seconds to load the entire page.
Is it the optimal time to load or it could be improved?
Please let me know.
Thanks,
--Subbu.

Hi Evnafets,
Thank you for the response.
Here are the tasks I am doing to display the data on JSP.
0. We are running on Tomcat 5 and the memory size is 1024MB (1GB).
1. Getting the data - I am not performing any database queries. The data is stored in the static cache memory. So the server side response is so quick - less than a milli second.
2. Using Java beans to pass data to the presentation layer (JSP).
3. 10 'if' conditions and 2 'for' loops and 2 'choose' statements are being used in the JSP page while displaying the data.
4. Along with the above, there are 4 javascript files are being used.
5. The jsp file size after rendering the data, is aprox. 160 kb
Hope this information helps you to understand the problem.
Thanks,

Deploying against a JSP site using JSTL

I am reviewing Contribute for use at my company. Our current
corp site is deployed in JSP and makes extensive use of the Java
Standard Tag Library, especially for writing dynamic URLs to
content such as images, pdf, and application download.
Can Contribute and/or my site be configured in such a way
that contributors can edit the JSP pages? I've exploded the war and
deployed it as a set of standard files so Contribute can access the
files, but Contirbute doesn't resolve the JSTL references.
Help!

contribute was designed to allow editting of static HTML
content only.. It does not have the capability to edit anything
dynamic.. It would be better to use Dreamweaver..

Calling a method that returns values in a map - using JSTL

Hi I have a method within an object that returns a List for a particular category
public List<String> getFieldsInCategory(String categoryName){
    return _categoryFieldsMap.get(categoryName); //This is a map that returns a list
}Trying to call the above function in jsp, the object is available as "document",
how do i pass a key to the above function to return a List.
   <c:forEach items="${document.fieldsInCategory('ABSTRACT')}" var="temp">How do i get the list by passing a string key to my method,
please let me know how to go about this.
Thanks

JSTL can not directly call methods that take parameters.
All it can do is access javabean properties - ie via the revealed get/set methods.
You can fudge it by having a seperate variable to set:
Map _categoryFieldsMap;
String category = null;
public void setCategory(String category){
this.category = category;
public String getCategory(String category){
return category;
public List<String> getFieldsInCategory(){
    return _categoryFieldsMap.get(categoryName); //This is a map that returns a list
}You would then do it like this in your JSP:
<c:set target="document.category" value="ABSTRACT"/>
<c:forEach items="${document.fieldsInCategory}" var="temp">
...The other alternative is to return the entire map to the page.
EL accesses maps quite handily.
so given a method that returns the map:
public Map getCategoryFieldsMap(){
return _categoryFieldsMap;
then the expression: ${document.categoryFieldsMap.ABSTRACT} returns what you are after.
Hope this helps,

Hi Chandran,
            I got that Idea too. I created a authorized customer, I created a authorized Object and assigned to a role.But in the role, when I am changing the object to generate profile, it is asking to select list of customers from the customer table.If the customers are always constant then this would work, but in my scenario, customers for the sales rep changes over time and when I ever reps open the query, they should see updated list of customers assigned to them only, as we update the master data everyday from source system and that shud reflect in the value help.
I am trying User Exit to achieve this, but I am not getting proper ideas how to do this.
Any Help on this issue with user exit code???
Thanks in Advance

Drop down values are missing while using the function module KCD_EXCEL_OLE_TO_INT_CONVERT

Hi all,
I am using the function module "KCD_EXCEL_OLE_TO_INT_CONVERT" to upload the excel template to an internal table but i am not getting the complete excel data into the table the fields which contains the drop down list values those values are not coming in to the table.
Is there any other function module which can read even the drop down list values? can any one please provide me the solution.
Thanks in advance
** FYI...i am using the below code:
* upload excel file to a generic table
   CALL FUNCTION 'KCD_EXCEL_OLE_TO_INT_CONVERT'
     EXPORTING
       filename                = l_filename

Print GregorianCalendar using JSTL

I have a GregorianCalendar property (for example exchange.rateDate) and I want to print it in a jsp page using jstl tags.
How can I solve this problem?
liviu

If the object you are trying to print is a GregorianCalendar, then you need to get the time property of the Calendar, which returns a Date object; the formatDate tag cannot handle a "raw" GregorianCalendar.
Using the previous example, it should be:
<%@taglib uri="http://java.sun.com/jsp/jstl/fmt" prefix="fmt" %>
<fmt:formatDate value="${exchange.rateDate.time}" type="date" dateStyle="SHORT"/>
<fmt:formatDate value="${exchange.rateDate.time}" type="date" pattern="dd/MM/yyyy"/>

Error while using Enumeration and Vectors

Hi all,
I am new bee in java i am using enumeration and vectors in my JSP page,

          String enumString = (String)enum.nextElement();
          String[] enumValue =request.getParameterValues(enumString);
          for(int n=0;n<=enumValue.length;n++)
          tempbean.dbRows.add(enumValue[n]);     //tempbean.dbRows is a vector,
if I seperate the For block out of While loop then im getting cannot resolve enum variable, bcoz its declared in while loop, I cannot declare it out side of while loop because I dont know the perfect size of the array and it will change dynamically.
pls help

Thankyou ,

How to populate a form based on values in a database with JSTL?

I know how to write Java code to connect to a database, but where exactly (and how) in my JSP page , using JSTL tags will I actually call the function that connects to the database?
Should the code to connect and populate the Java Bean fields go into the JavaBean constructor or anther method ( but from what I understand I can't really call the Java Bean's methods through JSTL - unless I did it througha scriplet)

I know how to write Java code to connect to a
database, but where exactly (and how) in my JSP page
, using JSTL tags will I actually call the function
that connects to the database?You won't. The point of writing JSPs with JSTL is to realize that the purpose of JSP is to produce HTML, and not to do extraneous things like accessing databases. You would write a servlet that connects to the database, extracts the data, and puts it somewhere the JSTL can find it. (Most likely in a List object in request scope.)
Then the servlet forwards to a JSP, where you use JSTL simply to scan through that List and convert the objects in it into HTML.

Send Vector class to JSP and print this Vector using JSTL

Hello All!
I need your help to solve my question.
I developed a Servlet + jsp application.
I tested it in local with Apache Tomcat/6.0.20 and it works correctly.
I write and use these classes:
class for execute query, and including data page:
package MySQL;
* To change this template, choose Tools | Templates
* and open the template in the editor.
import java.util.*;
import java.sql.Connection;

* @author initmax
public class MySQLQuery {
    private Connection CurrentConnect; //obj for connect to databae
    private Vector VectorPageObj = new Vector(); //save array object page, after execute query
public MySQLQuery() {}
//constructor accept current conection database
public MySQLQuery(Connection CurrentConnectBase)
    CurrentConnect = CurrentConnectBase;
//method accept name table and return all info on this table
public void SelectAllField(String NameTable)
       try
         Statement st = CurrentConnect.createStatement();
         String query = ("select * from "+NameTable);
         ResultSet resultQuery = null;
         resultQuery = st.executeQuery(query);
//step in cycle after execution query, and create Vector object
           while (resultQuery.next())
              GenPageMySQL PageObj = new GenPageMySQL();
              PageObj.setId(resultQuery.getInt("id"));
              PageObj.setTheme(resultQuery.getString("theme"));
              PageObj.setPage(resultQuery.getString("page"));
              VectorPageObj.add(PageObj); //add obj in tail vector
       catch (SQLException e) {
         e.printStackTrace();

      getpage = request.getParameter("page");
      out.print("MySQLConnectObj.GetConnection() = "+MySQLConnectObj.GetConnection());
//Check curent connect to database
      if(MySQLConnectObj.GetConnection() != null)
           MySQLQueryObj.SelectAllField("up_menu");//execution query
           MySQLConnectObj.DisConnected();
            request.setAttribute("up_menu_theme",MySQLQueryObj.getVectorPageObj(null));

//        MySQLConnectObj.DisConnected();
}I forward Vector "MySQLQueryObj.getVectorPageObj(null)" to JSP, how I can print data vector using JSTL?

your right, I learn Java however this very Interesting!
I change code, change Vector on List
class MySQLQyery:

    CurrentConnect = CurrentConnectBase;
//method accept name table and link on List, after work return all info on this table inside List
public List<GenPageMySQL> selectAllField(String NameTable, List<GenPageMySQL> ListPageObj) {
       try {
         Statement st = CurrentConnect.createStatement();
         String query = ("select * from "+NameTable);
         ResultSet resultQuery = null;
         resultQuery = st.executeQuery(query);
//step in cycle after execution query, and create Vector object
           while (resultQuery.next()) {
              GenPageMySQL PageObj = new GenPageMySQL();
              PageObj.setId(resultQuery.getInt("id"));
              PageObj.setTheme(resultQuery.getString("theme"));
              PageObj.setPage(resultQuery.getString("page"));
              ListPageObj.add(PageObj); //add obj in tail vector
       catch (SQLException e) {
         e.printStackTrace();
       return ListPageObj;
    *@set the CurrentConnect
    public void setConnection(Connection CurrentConnectBase) {
         CurrentConnect = CurrentConnectBase;
List<GenPageMySQL> ListPageObj;
            //get List<RowObject>
            ListPageObj = MySQLQueryObj.getListPageObj();
out.print("Size Page objects = "+ListPageObj.size());
            request.setAttribute("upMenu",ListPageObj);
            RequestDispatcher Dispatcher = getServletContext().getRequestDispatcher("/WEB-INF/jsp/index.jsp");
            Dispatcher.forward(request, response);string out.print("Size Page objects = "+ListPageObj.size()); == worked, I get count objects correct
How I can output fields Object GenPageMySQL in JSTL?
writing so:
         <c:out value="hello, Max" />
         <c:out value="${10+20/2}" />
         <c:forEach items="${upMenu}" var="Object" >
               <c:out value="${Object.getId}"> </c:out>
