JSP :: Download Data In Different Sheets In Excel

May 27, 2010

I have a requirement to download the data from DB to CSV/Excel. What I did is retrieving all the records from DB and store in the List and pass that list to the jsp page. In JSP page, I am using the below setting to download it to CSV/EXCEL.

response.setContentType("application/vnd.ms-excel");
String fileName = "Report"+System.currentTimeMillis()+".xls";
response.setHeader("Content-disposition","attachment;filename="+fileName);

It was working fine. But I have an issues in it. Excel is capable of storing it only 65,536 rows. Even all the data getting downloaded to CSV/excel (> 65,536), while saving I am getting error from excel saying that it can't save more than 65,536 rows and the below data won't be saved.

This workbook contains data in cells outside of the row and column limit of the selected file format.

Data beyond 256 (IV) columns by 65,536 rows will not be saved.
Formula references to data in this region will return a #REF! error.

I am not opt for POI apache third party at this point of time. Is it possible to download it in other sheets if it exceeds the max limit.

Example: Having data of around 100,000.

Download 65,536 - Sheet 1
Remaining in Sheet 2,3.. of the same excel.

Write A Java Program To Fill Excel Spreadsheet

Jul 15, 2014

I have an excel spreadsheet, with a specific filename and location which doesn't change (e.g. C:/workbook.xls)What I would like to do is have a window open when I open an .exe file, and in this window is a bunch of check boxes, text areas and drop down boxes (I can implement these, that's about my level of JAVA)

Then, when I click on a button in this window (for example, a button which says "Save"), the data from all these boxes and menus etc. goes into specific cells in the excel spreadsheet. Or if certain values are selected from a drop down menu, then a bunch of cells are empty.

Fill A Panel With Seats

Jun 13, 2014

We get a database and some DAO classes. We had to fill a ShowPanel with different shows being given in a theatre, and then when you choose from this you get several dates. Then when you click a date, the seatings appear in the SeatPanel. I got the first part with the shows and dates. But Im stuck at getting the seatings.We have a controller class which calls the shows+dates (this happens in one method). But i always get a nullpointerexception for the seatings. (this happens in a different method). I think i just don't know how to link the chosen show+date with the seatings.For the moment i have

public ArrayList<Seats> getSeating() throws SeatingException{
Show s = shows.getName();
ArrayList<Showdate> showdate = s.getDates();
ArrayList<Place> seating = new ArrayList<Place>();
try{
for (Showdate sd : showdate ){

[code]...

The given class PlaceDao has a static getInstance() method and an ArrayList<model.Place> getSeating(model.Showdate showdate) method.In the next stage i have to try and fill the panel with the seatings, but first i need to be able to call them.

Fill Different Size Boxes With Bags Most Efficiently

Jan 23, 2015

I have to write an example program to fill boxes most efficiently with bags. All bags are the same size. The boxes come in Large, Medium and Small. Large boxes hold 20 bags. Medium boxes hold 10 bags. Small boxes hold 5 bags. I am getting input from JOptionPane input dialog box and then parsing that input to an integer.

I have to fill the large and medium boxes completely. I am not sure how to do this without an if statement. I can use one, but we have not covered it in class, so I am skeptical about using one to solve the problem. If I just divide the input number with integer division, I'm not going to get the remainder, right? So I'm thinking that I can mod my input number by 20 (the number of bags the user inputs) and then mod that number by 10 and then mod that number by 5, would that work?

How To Deal With Exam Like PDF - Fill In Oval Image

Feb 1, 2015

So, let's say I have a pdf that looks like an exam or anything that has answer choices and an oval to fill in.

So, if I want to create a program that fills in some of those ovals, I would first need to find the coordinates? I can use something like gimp?

And once I have those coordinates, what do I do? Like do I extract the oval image and replace it with a filled in one? Is there a library that lets me do this - also lets me set the size to make sure the new filled in oval image is the same size?

Bingo Board - Having Array To Fill A Grid

Dec 16, 2014

I am attempting to make a 5x5 bingo board. My array generates 75 numbers(15 per bingo letter) and displays them in a random order. What I am having trouble figuring out is how to fill the 5x5 grid with 25 numbers from my array. And yes, my code is probably much longer and much more redundant than it needs to be. Also, I think I'm using cells and grids terribly wrong (possibly the entire java language) but I'm not sure.

import java.util.*;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JLabel;
import java.awt.event.*;

import javax.swing.JButton;

Swing/AWT/SWT :: How To Fill Text Fields With Selection From JList

May 2, 2015

I have an addressBook GUI where I have a JList that populates with the contacts names, and once I double click a contacts name I'm wanting to fill the textfields with the contacts corresponding data.

ex) ContactType: Family (enum), Name: Zoidberg, Address: 111 Space Drive, City: New York City, etc...

I've got it to where I select open from the JMenu, it populates the JList, but once I select a contacts name, all the textfields are populated, but only with the contacts name

ex) Name: Zoidberg, Address: Zoidberg, City: Zoidberg, etc....

What am i doing wrong here, and how can i fix it to where it fills out the correct data?

Here's my code so far:

public class AddressBookGUI extends JFrame {
private final int WIDTH = 450;
private final int HEIGHT = 300;
private JLabel currentlySelected;
private JTextField contactTypeTextField;

[code]...

I'm certain the logic is messed up near the end where i set all text fields to the index, because no matter what field i want to fill it's at it's going to set it to whatever index I select, but I don't know how to fix it.

Unable To Fill Blank Squares On Minesweeper Game

Nov 12, 2014

I'm having trouble filling in the blank squares on a Minesweeper game. What I am trying to is, if a user clicks a square and that square(s) does not have a bomb in it, or adjacent to it, should be set to an empty square.

Here's my recursive method below:

public void revealZeros(){
for(int x = -1; x <= 1; x++)
for (int y = -1; y <= 1; y++){
Square zeroSquare = (Square)board.getSquareAt(xLocation+x, yLocation+y);
if (!(zeroSquare.SquareHasBomb)){
setImage("images/empty.jpg");
}
}
revealZeros();
}

I am traversing around the square that the user clicks on with the use of two for-loops. Getting the square at that location and then applying an empty square image. On that square.

The function should then recurse itself and go onto the next square, if the next square does not have a bomb or does not have an adjacent bomb.

I keep on getting an infinite recursion problem

Calculate Cost To Fill A Pool Based On Its Shape / Length / Width And Depth

Sep 17, 2014

This program is for a swimming pool filling service company. They charge 2 cents per gallon and $50 per hour to fill a pool. The truck can fill at a rate of 730 gallons per hour.

Create the Pool class that calculates the cost to fill a pool based on it's Shape, length, width and depth. (Input order is S L W D)

The pool class will need data fields for String shape, double length, double width, double depth, static double GallonsPerSqFoot = 7.4805, static double price per gallon = .02, static double FillingFeePerHour = 50.0, and static double FillingRate = 730gal/hr.

Create a No-Arg constructor and a constructor that accepts the non-static values, and has the methods: getShape, getLength, getWidth, getDepth, getGallons, getHours, getFillingFeePerHour, getHourlyCost and getTotalCost.

At the end of the class, create a main() method that asks for the input and returns the output based on the Pool class gets.. methods.

The shape options are oblong or rectangle. (A round pool would be oblong with the same width and height, a square pool would have the same width and height)

Formulas:
Rectangle cubic ft = length * width * depth.
Oblong cubic ft= ((Math.PI * Math.pow(width/2,2)* depth) +((length-width) * width * depth))
Gallons = cubic ft * 7.4805.
hours = total gallons/730.
Total cost = (total Gallons * .02)+(hours * $50)

Example Output
An oblong pool 18.00 feet long by 12.00 feet wide and 5.00 feet deep will use 6923.10 gallons of water and take 9.48 hours to fill. The total cost will be 612.65.

Here is my code:

import java.util.Scanner;
import java.util.*;
public class Pool
{
private String poolshape1 = "oblong";
private String poolshape1 = "rectangle";
private double length;
private double width;
private double depth;
private static double GallonsPerSqFoot = 7.4805;

Implementing Methods - Draws Ovals Or Rectangles On Screen And Can Change Fill / Outline Color Of Shape

Oct 5, 2014

import model.Model;
import shapes.Rectangle;
import shapes.Shape;

[Code] .....

I have to implement the methods for what is happening if on some panel the action selected are Remove/Move/Change/Resize (Draw is already implemented).

The Applet in question draws ovals or rectangles on the screen and you can change the fill-color and outline-color of the shape. All this works already. I have dabbled with the move-method, but am not going anywhere.
