Inventory Form Program - User Update Data In The Table
Apr 30, 2015I'm getting ready to code a program that takes record of items loaned and return in a table. I want more than one user to access the program to be able to update the data in the table. For instance, if one user added 5 new items to the table, all other users would be able open the program to see a modified table with 5 new items. Was looking for some advice and was wondering if implementing a database would work best.
View Replies View RelatedProgram That Will Allow To Enter Information From Form To Keep Track Of Attorney Who Signed Up
Jan 13, 2015I work for my local probate court, and one service we offer is email reminders. They fill out a form, it's entered in the system, and they will be notified when something is due. I've been allowed to create a program that will allow me to enter the information from the form to keep track of the attorney's who have signed up.
import java.sql.*;
import java.util.*;
import javax.swing.*;
import javax.swing.table.DefaultTableModel;
public class Attempt1 {
public static void setConnection() throws SQLException {
Connection conn = null;
Statement state = null;
[Code] ....
The issue I have is the method setQuery. It displays a table with the data entered. Where it currently sits at line 21, it does not display the table, nor does it seem to terminate the program. The goal was to update the table with a few entries, and then display the Jtable. When placed above the setInsert method, it displays just fine, and will reflect the new entries added the next time you start it. I'm still learning Java outside of a classroom environment on my own, so I can only imagine that this is riddled with poor coding, but I just can't seem to figure out why it doesn't display the table after the setInsert method is called. In it's current state, this program is just meant to test functions of SQLite with Java. From there it will be created with a GUI.
Servlets :: HTML Form - Possible To Send Data (image / Text) Along A Single Form
Jan 8, 2015I want to understand how is it possible to send data (image + text) along a single form. Here is my code:
<form method="post" action="updateAccount"
encType="multipart/form-data">
<input type="file" name="file" value="Select image ..." /> <input
type="submit" value="Start Upload" /> <br>
<textarea rows="8" cols="54" name="about">Yes
EJB / EE :: Maintaining Values From Primefaces Form After Form Submit
Jan 29, 2015I have a form containing several fields, 2 of which persist to different table in a database than the rest of the fields on the form. I have no problem persisting the data into both tables of the database, and after the form is submitted I reset the form to its default values. That all works fine.
But in the same session, when I open another form (a search form) and enter search criteria, which then displays a datatable containing the search results, those 2 values that are persisted to another table are not showing up, but the rest of the data is.
Here is the method that calls the persist methods:
@ManagedBean(name = "foreignPartyController")
@SessionScoped
public class ForeignPartyController implements Serializable {
...
public void saveData() {
[Code].....
The values do show up, but the problem is, when a subsequent form is opened in the same session (e.g. a search form) the field for that value shows the actual value, instead of the field being blank.'
I am not sure why the data from the one database ("parent") is showing up, yet the data from the other database ("child") is not.
Is it something I am doing wrong? I thought by setting the setter in the child controller class back to a new instance of the Entity class (PolicyPayment) that it would reset the form to default values, but at the same time retain (or save) the inputted values in the same session.
JSP :: Synchronous Form To Asynchronous Form Submit?

Java Date Keeps Reverting To 1935 Form 2035
Aug 21, 2014Having an issue with an application I'm testing that takes in several Date parameters from a user, while testing I've noticed if i enter a date that's in or before 2034 everything works fine but once i go from lets say 21/08/34 to 21/08/35 the year reverts to 1935, not 2035.
I'm using the java.util.Date Class to store the Data entered... is there any known restrictions on the Date class that might be causing such an issue??

Program Prints 2 Values When It Should Only Print 1
Feb 4, 2015When I run this code, it is supposed to get one value from turnTimer(); and return it, just as a test. This works when I enter a valid pit. For example. If I were to input "A" when it's player one's turn, it will return 1, like it should. However, if I were to type "H" when it's player one's turn, it returns "Not a valid pit!"(like it should) but then it also returns 12. It shouldn't know that H is 12 because it's in a separate method. I'm confused as to why it's printing both values.
import java.util.*;
public class Mancala
{
static Scanner input = new Scanner(System.in);

Program Should Print Array As Output
Jul 11, 2014Write a program to create an integer array of size 20. Then, the program should generate and insert random integers between 1 and 5, inclusive into the array. Next, the program should print the array as output.
A tremor is defined as a point of movement to and fro. To simulate it, the program will generate a random number between 0 and 19, which represents the location in the array (i.e. index number). Then, the 3 numbers to the left and right of this location should be reset to the value 0. If there isn't 3 numbers to the left and right you may assume a lesser number depending on the boundaries of the array.
Then, the final array should be printed as output. There is no user input for this program.Your program must include, at least, the following methods:
-insertNumbers, which will take as input one integer array and store the random numbers in it.
-createTremor, which will generate the random number as the location and return it.
A sample run of the program is shown below:
Sample output #1:
Array:1 2 2 3 1 5 4 2 3 4 4 2 1 1 3 2 1 4 3 2 1
Random position: 5
Final Array:1 2 0 0 0 5 0 0 0 4 4 2 1 1 3 2 1 4 3 2 1
Java Servlet :: How To Receive Parameters From A Form And Insert Values In DB
May 23, 2012I'm trying to create a Servlet that takes input from a form and process it and insert it in database.tablename.
My MAIN ISSUE IS WITH THE NUMBER OF COLUMNS THAT WOULD BE DYNAMIC AND THUS CANT RECEIVE THE PARAMETERS IN STATIC CODE.
Here is the form code
<%@page contentType="text/html" pageEncoding="UTF-8"%>
<!DOCTYPE html>
<form action="Test" method="post" />
<table width="90%" border="1" cellspacing="1" cellpadding="1">
[Code] ....
And here is the Servlet
import javax.servlet.*;
import javax.servlet.http.*;
import java.sql.*;
import java.io.*;
public class Test extends HttpServlet {
[Code] ....
This is the basic code structure and I'm trying to figure out this special case with handling the multiple parameters:
I don't want to use String []a=request.getParameterValues("studentname"); as hard code. The reason being the number of rows will be diyamic and I would like to get the column name and then then use an array of string to take values. But how can I connect these to form a query so that the rows goes on inserted one after other.
Java Servlet :: Multiple Time Submission Of A Form Automatically In Struts
Jan 10, 2013I have a button in jsp, when the onclick event is fired, it will send the request to someaction.do to generate a report and display that report in a new window.
After clicking the button to generate the report, in the business class a sql query is getting executed.
If the query result has less data, then I don't have any problem, I could view my report page.
If the query result has more data, then the query takes at least 5-6mins to complete. However, before the query completes its execution, the same request is automatically invoked again. Due to this the report is not getting generated because [...of the multiple requests?], the browser shows an Internet Explorer error and ends up at a blank page.
No exception is thrown and the only place I could find the place of query execution it stops and starts as a new request from web.xml with Servlet Filters, Action.
Note: For a single .do request, the request is getting repeated for 3 times. Overlapping of request also takes place.
