JSF :: Values Aren't Displaying From Database

Mar 18, 2014

I am using primeface in this project. I have a database with orders, order details and customers. The index page displays the order details and I click on one of the orders I want the customer details of that order to be displayed. But right now when I click on an order the dialog box that appears is empty. I'm not sure if the problem is with the jsf for the customer class.

here is the jsf page:

<p:dataTable value="#{orderDetailsBean.list}" var="anOrder"
paginator="true" rows="10"
paginatorTemplate="{CurrentPageReport} {FirstPageLink} {PreviousPageLink} {PageLinks} {NextPageLink} {LastPageLink} {RowsPerPageDropdown}"
rowsPerPageTemplate="5,10,15">

Text Fields - Input String Character S

Aug 24, 2014

What should be the code if i want to input a different string in case of the typed string. The case is : I have a predefined string S = "Peter,please answer my question" and now when i input another string inside the text field character by character i want characters from the string S to enter instead of the input string. In short, the input string should be disguised as string S.

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.

Order Of Static Fields

Nov 20, 2014

I am unsure of something. In the following class, which is read first; the static field or the main method?

class Test{
static int a = 3;
public static void main(String args []) {
//some code}
}

I put some code in Eclipse and have tried to look at the hierarchy. It would point to all static fields being initialized in order from top to bottom, including the main method.I had thought that the main method was always the first thing in a public class to be initialized, regardless of where in the code it resides. Am I reading the Eclipse hierarchy wrong? I find Eclipse very difficult, especially since I typically code in Textmate. I just want to see how my code is operated upon,

Static Fields And Inheritance

Apr 17, 2014

If I define a class which contains a few static fields, and then have a few classes who inherit this class, then all these classes would have the static field as well. Now my question is the following: would all those sub classes (and the base class itself) share the same object, or would each class have one object for all it's instances?

Sending Values For GUI Fields

Jul 9, 2014

I have a simple class, called InputManager, which has methods that communicate with another class DatabaseManager which has access to Database which is actually object that contains information about actual database.

My JFrame has Navigation class (extends JPanel). There I put all needed JButtons, JLists and so on.. This class has instance of InputManager and when user interacts with GUI components inside of it, Navigation calls InputManager methods, it then analyses the call and calls needed methods on DeviceManager, which then sends queries to Database and etc.

The problem is, that at the beginning (when user runs a program), I want to get information (which is actually values for my GUI components ) from Database. It could, for example, create another DatabaseManager and connect to the Database to get information, but it is okay to have two objects?

I was also thinking about sending same DatabaseManager object through InputManager to Navigation, but it seems strange for me to have two objects, which can interact with each other in both directions(Class A has instance of Class B, and Class B has instance of Class A). Is there anything bad this can do?

Also what I noticed that it seems odd that GUI class would have to get information from database. (Logic in GUI class).

Pickup Selected Text File And Read Line By Line And Output Text Into Visual Text Pane

Dec 12, 2014

I am checking how to do following task.

01. pickup the selected text file and read the line by line and output the text in to visual text pane.

what i did:.

01. I wrote code that read the text file and output in to jave console/ also some of the interface.

the code read txt file:

Java Code:

String fileName = "C:/Users/lakshan/Desktop/lawyer.txt";
File textFile = new File(fileName);
Scanner in = new Scanner (textFile);
while(in.hasNextLine()){

[code]....

so it will read any text file dynamically and output to the text pane in interface. I think scanner code must be execute after the select the file from the browser and set the scanned result in to variable. then later out put the var as string in some jswing component?

Sorting Objects By A Number Of Fields

Mar 17, 2014

I am trying to find a concise way to write the sort methods for my class. I am supposed to make a program that can sort objects by a number of fields: year, rank, artist and title.

I used an idea from this thread : java - Sorting a collection of objects - Stack Overflow

And I am trying to use the custom comparator for my sort methods. However for some reason, the sortingBy variable fails to recognize any of the enum types.

Whenever I try to set the sortingBy variable equal to one of them, for example:

Java Code:

private Order sortingBy = Year; mh_sh_highlight_all('java');

I get a "Year cannot be resolved to a variable" error.

What I want to be able to do is make it so every time a specific method is called, say, for example sortTitle(), sortingBy will change to Title, then the SongComparator will sort using the case Title.

Is it possible to do this? I can't figure out how to modify SongComparator's object variables that way.

Java Code:

import java.util.Comparator;
public class SongComparator implements Comparator<Song> {
public enum Order {Year, Rank, Artist, Title}
public Order sortingBy;

[Code] .....

Sorting Of Multiple Fields Does Not Work

Nov 24, 2014

I am doing the sorting of multiple fields. This sorting requires to sort the emergency numbers first followed by queue time. However, the sorting is fail, which is the emergency numbers are sorted correctly only but not the queue time. I try to figure out the problem but unfortunately I cannot find where the problem is. Below are the codes for my assignment (Please take note that there is no need to check both ListInterface and LList class) :
 
public interface ListInterface<T> {
  public boolean add(T newEntry); 
public boolean add(int newPosition, T newEntry);
  public T remove(int givenPosition);
  public void clear();

[code]....

This is the attachment of the result that I ran earlier:

Capture.jpg

The first list is before sorting while the second list is after sorting.

Enum Properties / Values / Fields

Jul 11, 2014

So I have an Enum file with 119 constants and each constant of that type has 20 fields that come with it. All the fields are the same type and named the same (e.g. there are 119 of Object obj, one for each constant), and I want to run the same methods over them. Since the Objects of the same type are named the same for each constant, I just have them named explicitly in get-er methods.

This worked fine when I just put all 20 fields through the constructor and set them as fields under all the constants. But I realized that if I wanted to make an instance of this Enum class, I'd have to enter in all 20 fields when they are all a set of Objects with unique values. So I then put them as fields under their own respective constant to make it easier to create instances of this enum. But now my methods don't work.

A) I don't really understand why they don't work anymore?
B) Is there a way to fix it without putting all the methods under each constant?

Example:

public enum MyEnum {
AAA {
private MyObject obj = new MyObject (3.0);
},
BBB {
private MyObject obj = new MyObject (1.5);
},
CCC {
private MyObject obj = new MyObject (6.5);
},
DDD {
private MyObject obj = new MyObject (3.5);
};

public double getObjVal() {
return obj.value(); // it can't find this obj should I move it up to where the constants are declared?
}
}

Serialize And Deserialize To A File - Uninitialized Fields

Aug 27, 2014

My code's objective is to serialize and deserialize to a file. I'm in the process of revising the code to allow multiple serializations and deserializations, but for now the code's limited to one serialization and deserialization. I'm also debugging one error, before I debug several others. I've limited my debugging question by accessing the field of one deserialization.

This is the code on pastie: [Code] ....

How to display the code on coderanch? I don't understand how to use the code widget.

I can successfully serialize an object, but I cannot deserialize it and access its fields. If you execute the program, create a new file, add ONE FullTimeEmployee object to the file and then read its firstName field, you'll be returned null.

I'm certain I initialized the field by using a constructor. I'm also pretty sure that I correctly casted Object (if I'm not mistaken,the generic type for a deserialization) into FullTimeEmployee
