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;
I 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.
I have a button on UI which adds messages and when the user clicks on it the form gets submitted, meanwhile the user is clicking on refresh(F5) multiple times which is causing the same message to be displayed multiple times. To resolve this , I am converting the form from a synchronous submit to Asychronous but it is still not working. Below is the code:
I have a GUI that prompts the user for information. When they click 'submit', a new customer gets created from a class like so ...
Java Code:
public void actionPerformed(ActionEvent arg0) { Customer customer = new Customer(); // New customer object customer.name = view.getName(); customer.age = Integer.parseInt(view.getAge()); customer.ccn = view.getCCNumber(); mh_sh_highlight_all('java'); I am having difficulties validating my variables for nulls. For instance ...
Java Code:
// METHOD TO RETRIEVE TEXTBOX INPUT -- NAME public String getName() { String name = null; if (jtfFirstName.getText() == null || jtfLastName.getText() == null || !jtfFirstName.getText().matches("[a-zA-Z]+") || jtfLastName.getText().matches("[a-zA-Z]+")){ // Validate name fields JOptionPane.showMessageDialog(null, "<html><i>Improper Input Detected.</i>
[code]...
I can't seem to win with this. Whether the fields are filled in properly or not, I get the error message and the program continues to completion using the name "null".
i get this error when trying to Persist a customer Entity in my web application using netbeans with the default glassfish server persistence provider eclipselink(JPA2.0)
error is

the table that i want to write to has the following colums id ==> primarykey auto increment not null int name == varchar(45) not null phone ==> varchar(19) nationalIdNo ==>varchar(19) balance ==> bigdecimal(6,2) not null default(0.00)
in my addNewCustomer i only need to set name, phone and nationalIdNo only this is my code

How to highlight an inputText in JSF 2.0 when a server-side validation error occurs? I have the server side validation,if validation fails, text box color (style) should change. Else it should display in normal color.
I am Having trouble with my program to validate. It is outputting null into the validation statement then it brings back a run-time error to that validation Statement for the String.
public String validateData () { if (nm == null)nm = "Error! Must enter at least one character"; else nm = name; return name; }//end validation method
Why is this happening, and then once that is completed, why is the validation Sentence in tests Scores not able to validate. I traced it back to out put "Error, a number between 1<100".
public void validateTests () { String testschange; if (test1 < 0 || test1 > 100) { testschange = " You have entered an invalid number, between 1-100. Please restart!"; testschange = Integer.toString( test1 ) ;
I'm trying to learn java by making a login page using java, servlet, javascript, html and mysql. I can login with username and password, I can get all the information from database in the edit page. However, when I edit and click on "Submit" in EditPage.jsp, it gives HTTP Status 404. Same screen appears when I click on "Sign Up" from first page (NewFile.jsp) and click on "Submit" button after filling up user information.
I am posting all my code here but probably important ones are:
EditPage.jsp, Edit.java, EditDetails.java, UpdateUser.java and for Sign Up SignUpPage.jsp and Registration.java.
Firstly here are my error message and ss from my project explorer:
I'm a new Java user and I'm trying to code a simple login page. In first page (NewFile.jsp) users should enter their username and password and should click on "login", or click on "sign up".
1.) If user enters his username and password correctly, a login page (LoginPage.jsp) appears and says "welcome null" but it should show the name of that user instead of null.
2.) In that login page there is an edit button to edit profile information. When I clicked on it, every information is "null" and when I edit them and click on "Submit" button;
HTTP Status 404 - type Status report message description The requested resource () is not available. GlassFish Server Open Source Edition 3.1.2
that message appears.
3.) If I click on "Sign Up" button at the beginning, a registration jsp (SignUpPage.jsp) appears. After filling up text boxes and clicking on "Submit", same Status 404 screen appears.
I created a mysql database called "loginpage" using xampp. In that database there is a table called "users" and it has un, pass, name, surname, email and degree attributes.
import java.util.Scanner; public class Exercise1{ public static void main(String[] args) { String employeeName, employeeNumber, position, department ; double otpay, salary, deduction, hrs, rate ; Scanner input = new Scanner (System.in);

That's my codes but its wrong according to our prof. it should be in frame form. i don't know how to do it since i did not encountered framing since i was started in java.
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.
Using JSF framework. when you select one drop down value and click on refresh before submit the initial value got selected in chrome and IE .
But getting issue in firefox. The initial value is not populating.With the text box also the same issue. when we enter something and refresh before submit values are not refreshing in Firefox
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">
The class does get compiled but the submit button doesn't work?

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.
i have a jsp page which contains two text areas inside two separate form tags. i want to submit unicode date in one textarea and display it in another. But nothing is working for me. i have to show basically all Indian Languages and english as well. here is the code of it
I want to create a online examination system.i want to know to how to get questions 1 by 1 on the same jsp page and on clicking the submit button the result should be saved in database.
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.
In a form i used <h:commandButton> i called a Javascript function. Though the function returns false , form is submitted and action method is called. I used like this
I'm trying to right a GUI in swing, and as part of my program, I want to open a secondary window out of the main window when a mouse clicks on the main window. Then, once I click a button on the secondary window, I want that window to close and submit data to the main window (like an info form). I have almost figured out how to do this, except for one problem. By putting a variable inside my form window called "ready," and then in my main window running a loop that constantly checks if ready is true and doesn't proceed until its true, I can create the form window, modify the values in it (currently just one value called "difficulty" that's modified by a jSlider), and then when i click the "begin" button, ready is changed to true, the form window closes, and the main window can proceed. However, when I try to put the while loop checking the ready variable inside a mouseClicked method in the main window, the form window freezes when it opens, and you can't see any of its content or modify it in any way (you can't even close it).
Here is my code:
//form window class import java.awt.*; import java.awt.event.*; import javax.swing.*; import javax.swing.event.*; public class formWindow extends JFrame { private JTextField instructions1;
