Query data with some value & display in datatable at page

Question

hi,
I have bean and when user enter some page i use datatable to display some data from oracle:
<h:dataTable id="dt1" value="#{GetDataOracle.rep_tcok_pl2_connects}" var="item" bgcolor="#F1F1F1" border="10" cellpadding="5" cellspacing="3" width="70%" dir="LTR" frame="hsides" rules="all" summary="This is a JSF code to create dataTable." >i want to first user defined start date and end date of report, type it into the form and later click submit and display report.
I know how to do that not using framework, please tell me how to do that in JSF?
I have main Controller servlet and my Bean is sth like this:
package logic;
import java.util.ArrayList;
import java.util.List;
import javax.naming.*;
import java.sql.*;
import exception.NoConnectionException;
* @author pawel
public class GetDataOracle {
Connection con = null;
Statement ps = null;
ResultSet rs = null;
private List perInfoAll = new ArrayList();
private List rep_dws_wnioski_wstrzymane_cnt = new ArrayList();
private List rep_dws_wnioski_wstrzymane_graph = new ArrayList();
private List rep_tcok_ppi_connects = new ArrayList();
private List rep_tcok_pl_connects = new ArrayList();
private List rep_windyk_hip_umowa_to_call = new ArrayList();
private List rep_tcok_pl2_touchpoint_count = new ArrayList();
private List rep_tcok_pl2_connects = new ArrayList();
public List getperInfoAll() {
    int i = 0;
    try {
    con = Database.createConnection();
    ps =    (Statement) con.createStatement();
    rs = ps.executeQuery("select sso, fname, sname, lev, last_login, login_count from stg123054130.oraclereports_user order by sname");
    while(rs.next()){
      perInfoAll.add(i,new getUsersData(rs.getString(1),rs.getString(2),rs.getString(3),rs.getString(4),rs.getString(5),rs.getString(6)));
      i++;
    } catch (NamingException e) {
        e.printStackTrace();
        throw new NoConnectionException(); 
    } catch (SQLException e) {
        e.printStackTrace();
        throw new NoConnectionException(); 
    } catch (NullPointerException e) {
        e.printStackTrace();
        throw new NoConnectionException();  // obsluga bledy na wypadek jesli braknie wolnych polaczen do bazy
    } finally {
    try {
        if(con != null)
        con.close();
    } catch (SQLException e) {
        e.printStackTrace();
    } catch (NullPointerException e) {
        e.printStackTrace();
        throw new NoConnectionException();  // obsluga bledy na wypadek jesli braknie wolnych polaczen do bazy
return perInfoAll;
public class getUsersData {
String sso;
String fname;
String sname;
String lev;
String last_login;
String login_count;
public getUsersData(String sso, String fname, String sname, String lev, String last_login, String login_count) {
    this.sso = sso;
    this.fname = fname;
    this.sname = sname;
    this.lev = lev;
    this.last_login = last_login;
    this.login_count = login_count;
public String getsso() {
    return sso;
public String getfname() {
    return fname;
public String getsname() {
    return sname;
public String getlev() {
    return lev;
public String getlast_login() {
    return last_login;
public String getlogin_count() {
    return login_count;
}How should i send to my Bean info that i want data where:
select sso, fname, sname, lev, last_login, login_count from stg123054130.oraclereports_user
where last_login > to_date('20091101','YYYYMMDD')
order by sname;
?

Hi 404116,
Here's another method :
1. After you have queried the Block-3 <Subject Block> you have the Student-id from Block-2 which you can use to query the Block-1.
-- I will use the following code to query the Block-1
1. Check the Block Status of Block-1. As you have queried the Block-3 and Not Block-1, the Block Status of Block-1 should not be 'QUERY'.
2. If status of Block-1 is not 'QUERY' And
status of Block-2 is 'QUERY'
Then
/* The query process is reverse from Block-3 first */
2a. Use the Set_Block_Property Built-In to define the Where Condition for the Block-1.
Where column to Query = : Block-2.Student Id
2b. Remove the Relation between Block1 and Block-2 at Run Time.
2c. Go_Block ('Block-1');
Clear_Block (No_Validate);
Execute_Query;
And Remember,
1. To remove the Where Condition set in Block-1 when you query from Block-1 first
2. And re-define the MD relation from Block-1 to Block-2
