JSP :: Drag And Drop Images (single Or Multiple) To Upload
May 12, 2014
I am working on a piece of a code - drag multiple files from local window and drop it into a DIV in my application. And then I want to bind the file into Struts which is where I am having issues right now, snippet below :
<form id="upload" action="http://localhost:8080/XXX/xxx.page" method="POST" enctype="multipart/form-data">
<fieldset>
<legend>HTML File Upload</legend>
<input type="hidden" id="MAX_FILE_SIZE" name="MAX_FILE_SIZE" value="300000" />
[Code] ...
Is it an issue when I give the inputType name as userImage?

1: Have drag and drop of elements in jsps?
2: How I can create and store back the form attributes dynamically?

I am just trying to understand during a drag and drop how can I transfer the actual object instead of just creating a new one. I believe I am close but I cannot nail down where I am going wrong. Here is my code I am using to test this.
First/Main:
Java Code:
package main;
import javax.swing.SwingUtilities;
public class Main {
public static void main(String[] args) {
SwingUtilities.invokeLater(new Runnable(){
[Code] ......
When I drag the JPanels it just copies and makes a new one. I tested this by having a sysout send to the console a private int that I set during the initial creation of the object.

I am still learning how to perfectly use the netbeans palette. I just created a GUI and want to use jTable on it. I have also dragged and dropped jTable component on my GUI. What should I do thereafter? My aim is to allow user input figures into cells, sum up the figures and enter same into a database. I have not used jTable before in java.

For example, say I have I BoxLayout with a few JButtons in it. How could I make it such that I could drag a JButton such that it could be in front or behind the others?
I've thought about using ComponentMover and just switching to a null layout right before moving it and switch it back right after like bellow, but I'm not sure how to make it keep the change in order.
import java.awt.LayoutManager;
import java.awt.event.MouseEvent;
public class LayoutComponentMover extends ComponentMover
{
private LayoutManager layout;
[code]....

Is it possible to "drag & drop" controls from a db to the form design in Netbeans? InVB this is possible. How about Java - Netbeans?

How do I keep an item (TreeItem) from being selected when performing a drag -n- drop? I don't want it to be selected because it will end up making the target disappear (selection of TreeItem changes target panel).
Related question: Is there a way to "veto" a tree selection change as well?

I am trying to drag and drop tree nodes within the same JTree. I have a code which uses Java 1.2 java.awt.dnd.I would like to use TransferHandler and newer implementation.I have found a code which works when JTree is drop target but there is no code where Jtree is drag source and drop target.

I am not all secure on the execution of the fileupload Primefaces.
The uploading execution occurs normally, but I would like to have a counter that control's the received files. The problem is that sending files go by so fast by this method that appears to be running in parallel. My question is whether this behavior is normal while sending files.
If it is not, where may be the error. If it is normal what can i do to make the counter really take the right value?
I'm using the scope of the "bean" type of view, but when im trying to run the session the problem also occurs depending on the file size.
If my files are very small, the execution is very fast and I cant follow the counter. If I clean the code the execution usually occurs no matter the size of the files.
@ManagedBean (Name = "bean")
@ViewScoped
public class BeanUpload {
private int counter;
@PostConstruct
public void init () {
counter = 0;
[Code] .....
The result on the console for 3 files is:
COUNTER EX: 1
COUNTER EX: 1
COUNTER EX: 1
If I run the code in debug mode on the console this is the result:
COUNTER EX: 1
COUNTER EX: 2
COUNTER EX: 3
Versions: Mojarra 2.1. Primefaces 5.1.15

My application depends on eight default user roles (or account types). They can be renamed or disabled, but should not be deleted. I want to protect them from deletion using their uuid value from the db. How can I pass their uuids into a single variable so I can use that single variable in my conditional statement? If I should use an array, any example of how I might do this?

This particular program is supposed to prompt the user to input either an uppercase or lowercase Y to process a phone number, they are then prompted to enter the character representation of a phone number (like CALL HOME would be 225-5466), this repeats until the user enters something other than the letter Y. All of the words entered are to be stored into a single array. The program is then to convert these words in the array to actual phone numbers. Here is what I have so far.
import java.util.*;
public class Program1 {
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
String begin;
int phoneNumber = number.convertNum();
[Code] ....
I realize that the second method doesn't have anything to return yet, I just wanted to put that in there while I was doing things that I actually know how to do ha. The convertNum() method is supposed to be the method with which the array of characters is converted to phone numbers.
I'm still trying to think my way through this. I would think it'd be easier to store the inputs from the user as individual letters rather than words for the sake of converting to phone numbers.
Also, we are only supposed to recognize the first 7 letters of each word that is entered, like the CALL HOME example, there are 8 letters but it's still a seven digit phone number, so I'm not sure how that would work.
Also, when printing the phone numbers after they've been converted, we're supposed to print the hyphen after the third number, I have no clue how that would be done from an array.

I have got a pretty good framework working for my hangman game so far, however I am quite stumped on how to find multiple instances of the same letter in a single string. I am using indexOf to find the instance of a character in a string, but it only returns the first instance. So if the words(s) contain(s) multiple instances it doesn't register the rest.
public static void main(String[] args) {
String word = "crazy horse";
String answer="";
String space=" ";
String dash="-";
