How to fetch data from Database using SUP MBOs

I'm learning to develop blackberry apps using SUP.I am new to both blackberry api and SUP.
I need to make a login page for a Student and then validate the username and password entered using data from a database.
I need to check the database for the username and password entered. What should be my next step? How do i get this data from the database. Using findAll() method is not working . Do i need to connect to SCC or unwired server first. If yes , then someone please provide a sample code for it.

Hi!, I see your code and I see that you have a fee errors, try to use this:
import java.text.*;
import java.sql.*;
import java.util.*;
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
import java.io.OutputStream;
* NOTE: You must put the try-catch and your sql code into the get method
/** Servlet program to take fetchdata from database and display that on the broswer*/
public class Fetchdata
    extends HttpServlet {
String query = new String();
String uid = "ashvini";
String pwd = "******";
public void doGet(HttpServletRequest request, HttpServletResponse response) throws
      ServletException, Exception {
    try {
      Connection con = null;
      Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
      String url = "jdbc:odbc:Testing";
      con = DriverManager.getConnection(url, uid, pwd);
      Statement s = con.createStatement();
      query = "select * from gowri.msllst1";
      ResultSet rs = s.executeQuery(query);
      response.setContentType("text/html");
      ServletOutputStream out = response.getOutputStream();
      out.println("<HTML>" + "<BODY BGCOLOR=\"#FDF5E6\">\n" +
                  "<H1 ALIGN=CENTER>" + title + "</H1>\n" +
                  "<table>" + " <th>ITEM Code</th>");
      while (rs.next()) {
        out.println("<tr><td>" + rs.getString(1).trim() + "</td></tr>");//I change </tr></td> for </td></tr>
      } //end of while
      out.println("</table></BODY></HTML>");
    catch (Exception e) {
      System.out.println(e);
} //end of doGet method

How to fetch data from database in javafx 2.2 table which is editable.

Dears!
I want to fetch data from database in javafx 2.2 tableformat with jdbc , which is also editable and i can add more records in this table also.
Can anybody help me

I can vaguely recall some sort of JavaFX database connectivity feature, I'm not sure if it's valid anymore.The link is based on JavaFX Composer which only applied to NetBeans 6.9 and JavaFX 1.x (both of which are now dead techs).
There is a good chance you will have to write your own. There are several blogs describing other peoples' work. You could probably use them as a reference.Here is Narayan's basic [url http://blog.ngopal.com.np/2011/10/19/dyanmic-tableview-data-from-database/] tutorial for displaying data from a database in a TableView, you'll need to look elsewhere for the editing portion.
The [url http://docs.oracle.com/javafx/2/ui_controls/table-view.htm]JavaFX TableView tutorial gives info about how to handle edits in a TableView, but you will need to tie the updates back to the database yourself.
It is possible that [url http://www.javafxdata.org/]DataFX may provide some facilities to help support you.

Now, the problem is that I want to use this code in Scene Builder fxml ComboBox .
Please Help Me!
I shall be very grate full to you for this kindness.

Hi,
Ok, so you create your FXML :
Add a controller property to your root control. (See Code tab in SceneBuilder or direcly in FXML : fx:controller tag)
Add a fx:id to your controls (your combobox) (First property in SceneBuilder or directly in FXML : fx:id)
Example :
<?xml version="1.0" encoding="UTF-8"?>
<?import java.lang.*?>
<?import java.util.*?>
<?import javafx.collections.*?>
<?import javafx.scene.control.*?>
<?import javafx.scene.layout.*?>
<?import javafx.scene.paint.*?>
<HBox prefHeight="-1.0" prefWidth="-1.0" xmlns:fx="http://javafx.com/fxml" fx:controller="org.lgringo.comboexample.Controler">
<children>
    <TextField fx:id="text" prefWidth="100.0" />
    <ComboBox fx:id="combo" prefWidth="200.0">
      <items>
        <FXCollections fx:factory="observableArrayList">
          <String fx:value="Item 1" />
          <String fx:value="Item 2" />
          <String fx:value="Item 3" />
        </FXCollections>
      </items>
    </ComboBox>
</children>
</HBox>Then, you create your Controler class using @FXML annotation (name of control should be the name of fx:id properties)
You can do some initialisation in the inherit method "initialize"
Example :
package org.lgringo.comboexample;
import javafx.fxml.FXML;
import javafx.scene.control.ComboBox;
import javafx.scene.control.TextField;
public class Controler {
     @FXML
     // fx:id="combo"
     private ComboBox<String> combo; // Value injected by FXMLLoader
     @FXML
     // fx:id="text"
     private TextField text; // Value injected by FXMLLoader
     @FXML // This method is called by the FXMLLoader when initialization is complete
    void initialize() {
        assert combo != null : "fx:id=\"combo\" was not injected: check your FXML file 'ComboboxExample.fxml'.";
        assert text != null : "fx:id=\"text\" was not injected: check your FXML file 'ComboboxExample.fxml'.";
        // Initialize your logic here: all @FXML variables will have been injected
        combo.getItems().clear();
        combo.getItems().addAll("John Lennon","Mick Jagger","David Bowie");
        combo.getItems().add("Others...");
        text.setText("List : ");
}Then you use the FXMLLoader class to load your FXML and Controler.
Example :
package org.lgringo.comboexample;
import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.stage.Stage;
public class App extends Application {
      * @param args
     public static void main(String[] args) {
          App.launch(args);
     @Override
     public void start(Stage primaryStage) throws Exception {
          Parent root = FXMLLoader.load(getClass().getResource("ComboboxExample.fxml"));
          primaryStage.setTitle("Combo Example");
          primaryStage.setScene(new Scene(root, 300, 275));
          primaryStage.show();

Fetch Data from Database using JSP

Dear friends,
I am developing a portal for my College. The theme is to automate student details.
Here i have Screens for Posting, Editing , Viewing.
In Editing: I fetch the data from the backend using select query.
In the address field: I have value as "Big House".
The user keyed with double quotes when he keyed.
During extraction of the data i put the value inside a textbox as
<input type=text name=st1 value="<%=res.getString("street1")%>">
Here,
the value becomes as
<input type=text name=st1 value=""Big House "">
Here, you can notice that Big house i prefixed by double -double quotes.
The value should be Big House but the values is empty.
What i should. ???
Thanks in Advance.
Rengaraj.R

Try this:
<%
String addr = res.getString("street1");
//escape the double quotes from the address
addr = addr.replaceAll("[\"]",""");
%>
<input type="text" name="st1" value="<%=addr%>">

<jsp:plugin type="applet" code="NewJApplet.class" codebase="applets"
width="600" height="300">
<jsp:fallback>Could not load applet...</jsp:fallback>
</jsp:plugin>
if i view it in using AppletViewer it runs perfectly and display the data in JLabel. (ie, both jlblTitle and jlblNewTitle).(ie, DATA FETCHES FROM db AND DISPLAYS PROPERLY)
BUT IF I CLICK ON INDEX.JSP, ONLY jlblTitle APPEARS. jlblnNewTitle WILL BE BLANK(this label name is supposed to fetch from database)
EVERY THING IS DISPAYING PROPERLY EXCEPT DATA FROM DATABASE!!!
i signed the applet as follows :
grant {
permission java.security.AllPermission;

How to display data from Database individually??? Anyone can help ?

HI,
i i had select a row of data from database using ,
/* Query * From Table RESOURCEORDER where po = selected no and project = selected project */
     public ResultSet getAllData() throws SQLException
     getConnection();
     Statement stmt = conn.createStatement();
     ResultSet rs = stmt.executeQuery("SELECT * FROM RESOURCEORDER WHERE PROJECT = '" + getSelProject() + "' and PURCHASEORDERNO = '" + getPo() + "'" );
     return rs;
After that , how do i display the data individually ?
Eg select data is ('projectA','7891203-1', '10-4-2005','lcd',2000,'121-45217-8','electrical','pending','donwong')
i want to display them individually, like this in a page
Projectname: /* should display the Project A*/
P.O no:
Date:
Order:
Cost:
Acc no:
Type:
status:
Orderedby:
Can anyone help ? cos i'm new to JSP ......Thanks alot!!!!!
Regards,
khim

I assume PO being a unique key, will always return 1 row from db.
public String[] getAllData() throws Exception
getConnection();
Statement stmt = conn.createStatement();
ResultSet rs = stmt.executeQuery("SELECT * FROM RESOURCEORDER WHERE PROJECT = '" + getSelProject() + "' and PURCHASEORDERNO = '" + getPo() + "'" );
String [] returnValue = new String[9];
while(rs.next())
returnValue[1] = rs.getString("colname");
returnValue[2] = rs.getString("colname");
///and so on
return returnValue;
}Once you get that you could individually view it by setting a loop to run through the returned array.
Hope it helps

Hi Venkat,
I guess you mean an infocube from the SAP BI product. I propose to look at the forum for Business Intelligence to find your answers.

Question regarding Polling data from database using DB Adapters in BPEL

Hi,
I have the following question regarding Polling data from database using DB Adapters in BPEL -
If I am selecting data from multiple tables/view to ultimately generate hierarchical xml document, is there a way that I specify polling all of these tables/views. Is polling limited only to one table/view?
Thanks
Ravi

Hi Ravi,
your question seems to have been answered for the question of polling a set of tables with one as the root, and getting back a hierarchical xml representing multiple related tables.
However you can also poll for changes to both the root table and its related tables. Not sure if this was your question or the one already answered. If the former please check out the sample

Thanks
