JSF :: Submit Text That Will Be Displayed In List Of Paragraphs
Nov 17, 2014
I'm new to JSF and I'm facing a problem with displaying German umlauts correctly.
I have built a site that uses an inputText to submit text that will be displayed in a list of paragraphs (as simple html... <li><p>text</p></li> etc.). A managed bean is used as a controller to store data in backend and to retrieve it from backend for display. In backend the data is stored in a list of strings and using annotations this data is written to respectively read from file system on shutdown/startup via serialization. Sometimes when I'm sending German umlauts from my webbrowser they're not displayed correctly, other times however they are which is pretty weird to me.
I've built the project with NetBeans 8 and I made sure that under Properties -> Sources the Encoding is set to UTF-8. In the xhtml page for display the encoding is set as follwed:
<?xml version="1.0" encoding="UTF-8"?> //first line
<meta http-equiv="content-type" content="text/html; charset=utf-8"/> //in the head
<h:form [...] acceptcharset="UTF-8"> //all forms surrounding the inputText and the paragaraph list
I'm developing on a Ubuntu 14.04 desktop. For deployment I transfer the .war file via ssh to my server which is Ubuntu server (currently not sure which version, might be 12) and there I deploy the .war file on my Glassfish server online.
An example of how the input appears when it's incorrectly displayed: ä
The same letter appears like this when it's correctly displayed: ä
Another example, incorrect: ö
correct: ö
Once the data is input its appearance won't change anymore so I assume the incorrect encoding happens already before the data is stored in backend. I'm not sure yet under which conditions the data is displayed incorrectly.

Here I would like to collect automatically in a file ( txt) the characters displayed on the screen. I'm working on a system that the database is remote. To receive information, there is a terminal by which sends commands. The feedback is displayed only on the screen and you can only print. This is actually a terminal black screen, white character, such as command line "DOS" . The software can not export , or access to the database or other means of information retrieval .
I explored the track of the OCR . But the result produced is not consistent with the captured picture. How can I do this? I have no other tracks ....

Trying to read integers from a text file and place them in a linked list in order. Program is compiling and running fine, just not the way I am intending when I am calling the methods. (Note: You have to enter the file location in the var x if you plan on running this.)
import java.io.*;
import java.util.*;
public class Node {
public int value;
public Node next;
Node(int x) {
this.value = x;

How can i convert this linked list code to a read from input.txt
The first line in the input file will give the elements to initialize the linked list with. Consecutive lines will provide operation instructions.
Your code should read one line at a time. After reading each line, it should perform the corresponding operation and print the linked-list on the console.
If an operation is not possible, it should print "N/A".
Sample input file. Please note, the comments (// ...) are given for explanation, the input file will not have them:
4, 5, 6, 3// First line. This will provide the initial values for the linked list : 4->5->6->3
1, 9// Add a 9 at the front of the linked-list. After this operation the linked-list should be: 9->4->5->6->3
2, 1// Add a 1 at the end of the linked-list. After this operation the linked-list should be: 9->4->5->6->3->1
3, // Delete the first node in the linked-list. After this operation the linked-list should be: 4->5->6->3->1
4, // Delete the last node in the linked-list. After this operation the linked-list should be: 4->5->6->3
5, 11// Delete the node with the value 11 in it. Since this is not possible, it should print "N/A"
5, 6// Delete the node with the value 6 in it. After this operation the linked-list should be: 4->5->3
Sample output to the console:
4->5->6->3
9->4->5->6->3
9->4->5->6->3->1
4->5->6->3->1
4->5->6->3
N/A
4->5->3
My Code:
LinkedList.Java
class linkedList
{
protected Node start;
protected Node end ;
public int size ;

I have a list of objects in my bean (ex: List<Apple> applies = new ArrayList<Apple>() ).The object has several fields (ex: supplier, color, width, height, breadth, etc.)I want to show this list on the front end. However I also want to allow the user to edit the attributes of the apples.So from the front end I will have like a list of fields where a set of fields is related to a single object in the list.I would also like to add/delete apples.
What first came to my mind is to map every field in the object Apple to a List. For example if Apple has field suppliers and field color then in the bean I would create two Lists, List<String> supplier, and List<String> color.From the front end I would display the contents of these Lists rather then the List<Apple> apples.T
he name of the field would be the same for each set of attributes.On save (form submit) the Lists would be re-populated with the field values (changed or not) and then I would be my Apple objects from the bean before saving in database.However I am not sure if there is something in JSF that can achieve this in a simple way, working only with List<Apple> rather than adding additional Lists.

A user can dislike/like a topic. However I have to submit buttons in my jsp file, the issue is that when a user presses like/dislike it should print out on the consile line. It does that perfectly but it prints out both when it should only print out either like or dislike.
My JSP code:
<form name = "ViewTripServlet" action="ViewTripServlet" method="post">
</br>
</br>
</br>
<input type="image" name = "like" value="submit" src=images/like.png onMouseOver="this.src='images/like.png'">
</br>
</br>
</br>
<input type="image" name = "dislike" value="submit" src=images/dislike.png onMouseOver="this.src='images/dislike.png'">
</form>
Servlet Code:
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
ViewTri vT = new ViewTrip();
vT.user_like(request.getParameter("like"));
vT.user_dislike(request.getParameter("dislike"));

In my web application (jsf 2.2 + prime 5), when I click the submit button, JSF says: "validation error". I think the problem is related to my equals method contract.
Debugging the equals method, the type received by this method is "Short" (my PK type) and not the object type to compare (professional type in this case). So, equals will return false always!
PK declaration in Entity Class
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
@Basic(optional = false)
@Column(name = "id")
private Short id;
equals method:
public boolean equals(Object obj) {
if (obj == null) {
return false;
[Code] ....
Is this correct?

I have created a gui which accepts username in the text field and once clicking on submit button it fetches user details and throws it on gui via JTable.
But when i click submit for the second time using different username the background process goes well and good the vector that i pass to jtable changes with new data but the values in gui still contain the old data.

I am writing this program for my Java level 1 class. I am able to get it to compile and run, however nothing is outputted. Below are the instructions and the code that I have written.
Instructions:
Write an application that calculates and displays the amount of money a user would have if his or her money could be invested at 5 percent interest for one year. Create a method that prompts the user for the starting value of the investment and returns it to the calling program. Call a separate method to do the calculation, and return the result to be displayed.
Below is the code that I have written
import java.util.Scanner;
public class Interest
{
//main method
public static void main(String[] args)
{
originalAmount();
Scanner input = new Scanner(System.in);
