My query retrieves more than 5000 records from Oracle database. I want to display the records 100 per page. I know it is called pagination. Any detailed styp-by-guide or tutorial or example available?
View RepliesI have done 90% of the coding however i am stuck with producing the output, i just cant get the user fields to show.
I have attached a picture of the output that is required. The program consists of two classes i have attached the database class, and have inserted my coding below.
import java.sql.*;
import java.io.*;
import java.util.*;
public class QueryDB {
private Connection con = null;
String userID,

I have to get my output to show as per the image attached i am very close but not there yet. I have also attached the database where i extract my information from

here is the code,
ResultSet rs = result.executeQuery(selectsql);
int columns = rs.getRow();
while(rs.next()){

I can print out the result correctly, there are three rows of result from the database, but they are shown in one row on the browser, how could i show the result one row after another to let it looks pretty?

I am unable to get a best code for this and trying since long time.
I have a Stock Database query class, it compiles and runs well. Thing is when i enter a user, it shows a user stock information but it repeats showing the same user in the command prompt. the repetition is so fast, you can't see the information. All i wanted was the application to show a user's info, then asks you to enter another user again and so forth. Here is the code
import java.io.*;
import java.sql.*;
import java.util.*;
public class StockDatabaseQuery {
public static void main(String[] args)throws Exception {
String userID;
String firstName;

I have code which query value from database, the use case is the user can enter value as 1,01,11 in database but when the user enter value in xml file he can only enter 11,01,12 in database there is two columns lets say column test1=1 and test2=2 combination of this is 12, which is the value the use will enter in xml, but sometime the use can enter test1=04 than column test2=00 how can i approach this
I got table called card with column crdind,crdpos1,cardpos2 as primary key. The user can enter value as
crdind=1
crdpos1=5
crdpos2=3
inactivedate=2013-05-24
activedate=null
another row
crdind=1
crdpos1=5
crdpos2=5
inactivedate=2013-05-24
activedate=null
another row
crdind=6
crdpos1=02
crdpos2=00
inactivedate=2013-05-24
activedate=null
The rule say if you enter one number in crdpos1 eg 2 than you must enter value in crdpos2 it can be any number 1-9 but if you enter 00-09 in crdpos1 than crdpos2 is 00
The challenge I have is to query this value after they been enter. I have xml file which got field crdpos the use enter 15 which is the combination of column crdpos1=1 and crdpos2=5 ... How can I split the value crdpos and got and able to query in database in two separate column ....

I am trying to make connection with oracle database but when i run java file it's raise an error

I want to store an image/file into oracle database using jsp.

I want to create an application wich can handle xml files ( display xml files's data on a html page) + insert those data into an oracle database.
I'm new to that, it a project for my internship. wich API is the most appropriate for that ( Jdom or Xstream or other), wich framework i can use ( there is only 3 IHM : connexion, upload file, display data, confirmation insertion data)?
I have small Java code, which execute every day and checks for data in database using Cronj Schedular and everything works fine, but recently I have observed that, it is failing due to
java.sql.SQLException: No suitable driver found for jdbc:oracle:thin:@160.110.xx.xxx:1521/test
At the same time, when I run my test code to check Database connectivity that works fine without above exception. I'm unable to figure it out. Although, there was just slight code change, but that was nowhere related to Database or Database connection.
dbconf.java
public class dbconf {
private Connection connect;
private String connstr;
public Connection getConnection() throws SQLException {
connstr = "jdbc:oracle:thin:@160.110.xx.xxx:1521/test";

I am learning how to program in JAVA servlet+MySQL. Decided to make a simple program where it shows who is celebrating birthday today by retrieving data from database. At the moment I managed to get it working by loading a form.html and pressing the button in it which gets to the result.jsp and shows results there.
My plan was to get a list of people who are celebrating there birthdays initially when the website is loaded/being loaded, I mean when you enter URL into your web browser and you get it instantly in browser. Is there a way to do it the way I want (JAVA+servlet+MySQL) instead of pressing a button/link?

TabPane and Pagination controls. However, I would like to be able to create a vertical toolbar that controls page or tab display.
Is it possible to create a Pagination with no page control? Or is my guess of sizing the Pagination control so that the lower section is off of the displayed window, thus hiding the page info? Or, is it possible to create a TabPane with panels, but no tabs?
