JSF :: Passing Content Of Input-text To Bean?

Apr 8, 2014

I have an xhtml file with this content:

<h:inputText tabindex="7" styleClass="input" id="title" value="#{register.title}"
required="true">
</h:inputText>

Basically I want the user to enter his title (e.g. Mr., Dr.), which would be passed on to a bean which would send this information to me in email.

I also have a bean called register, along with setters and getters:

private String title;
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}

I want to pass this information to a String called body, within the bean:

body = body+"Title: "+this.title+"
";

I would then send the String in an email.

Passing Java Bean Name In A Method

Jun 13, 2014

Here I am taking response data from JSON using jackson API.I found a feature like using Jackson the properties can be set to bean properties.
 
private static String readUrl(String urlString) throws Exception {       
BufferedReader reader = null;       
try {           
URL url = new URL(urlString);           
reader = new BufferedReader(new InputStreamReader(url.openStream()));     

[Code] ....

I got the correct output here. But now I want to generalize my method into a utility class so that I can reuse the same method for setting response data directly to respective beans as given below:-
 
My question is how will I pass the bean object in my utility class?

public static Object getResponseData(String response,[b]String bean[/b]) throws Exception {       
ObjectMapper mapper = new ObjectMapper(); 
mapper.configure(DeserializationConfig.Feature.FAIL_ON_UNKNOWN_PROPERTIES, false);       
JsonNode root = mapper.readTree(response);

[Code] ....

Swing/AWT/SWT :: Reading From HTMLEditorKit Doesn't Display Text While In Text / HTML Content Type?

Apr 24, 2015

I'm working on a simple text editor, and I'm currently saving the contents of my JTextPane in a file using an HTMLEditorKit (text is a JTextPane):

private void save() throws IOException {
int returnVal = fc.showSaveDialog(window);
if (returnVal == JFileChooser.APPROVE_OPTION) {
StyledDocument doc = (StyledDocument)text.getDocument();
HTMLEditorKit kit = new HTMLEditorKit();
BufferedOutputStream out;

[Code] ....

The problem I'm having is that after opening a file that I saved, it does not display (if I disable text/html, it displays the entire html code, but when I re-enable it, nothing displays at all.) Am I loading it wrong, or am I setting the JTextPane's text incorrectly? Or is it, perhaps, another error that I didn't catch?

Reading / Outputting A Text File With Modified Content

Feb 15, 2014

This is sort of like the last problem I had but it's all about the formatting at the end. I have a file that reads something like:

Name
a bunch of text here
and perhaps a second
or even a third line

I need to output this as:

Name; "a bunch of text here and perhaps a second or even a third line"

Right now I find 'Name' and it outputs:

Namea bunch of text here and perhaps a second or even a third line

How would I add ";" and quotes in the middle? I can imagine that I may need to find name, then skip to the next line and just add name manually as the variable output of the search string.

This is where I am now

public static void main(String[] args) {
boolean output=false;
String name="";
String junk="CHAMBERS";
TextIO.putln("Search for a name");
name = TextIO.getln();
TextIO.readFile("doc.txt");

[Code] .....

So I'm almost there, but those dange double Names are killing me. I tried to add a bit of code where:

if (line.indexOf(name) >= 0){}

Reading Input From JTextField And Passing It To Another Class

Sep 7, 2014

I am having trouble taking user input and passing it to another class as a variable. If I assign the value explicitly (see line 59), it works just fine. What I want to do though, is assign the input from inputField to the variable inputVariable. I tried using:

inputVariable = inputField.getText();

This does not work. Regardless of what is typed into inputField, the output I get is just:

"The user typed "

package example;

import java.awt.BorderLayout;
import java.awt.Dimension;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.JButton;
import javax.swing.JFrame;

Enterprise JavaBeans :: Calling Singleton Bean From Session Bean Returns NullPointerException

Feb 23, 2013

I am doing this

@Startup
@Singleton
@ConcurrencyManagement(ConcurrencyManagementType.CONTAINER)
@Lock(LockType.READ)
public class ResourceBean {

[Code] ....

And I call this singleton bean from a stateless session bean like this

@Stateless
public class ClientBean {
@EJB
ResourceBean resource;

public String create(String r)
{
String res=resource.returnString(r);
return res;
}
}

But resource.returnString(r); gives a org.apache.jasper.JasperException: java.lang.NullPointerException I started the glassfish server in debug mode and found out that "resource" was null. but @PostConstruct in singleton does print which means singleton bean exists.

Can we call singleton beans with no interface in such a way form a session bean? I actually want to acquire instance of singleton bean when a client invokes method in Client bean...

Generate QR Code From Input Text And Display Information About Input / Output Bits

Nov 12, 2014

I am trying to write a program that will generate a QR Code from an input text and also display some information about the input/output bits. So far I have created the frame and what to do next. And I'm not sure if I am on the right track since my level of programming is not that great. By the way, I am using zxing libraries from GitHub. I know, there are plenty of generators online for the QR Code, but that is not what I am looking for. As you can see on the attached image, I am more interested in the efficiency of encoding 2D data. Also, I noticed that almost all the online projects regarding 2D codes are for Android. Which is not very useful.

// QR Code Generator
package qrcode;
import javax.swing.JFrame;
import javax.swing.JButton;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.JTextField;
import javax.swing.border.EtchedBorder;
import javax.swing.border.TitledBorder;

Swing/AWT/SWT :: Can Text Area Also Be Used For Input

Apr 7, 2014

I have a popup that displays textual info and sometimes gets text input from the user. I'm using the following code:

JTextArea textArea = new JTextArea( getGameHistory( true, -2 ) );
JScrollPane scrollPane = new JScrollPane(textArea);
textArea.setLineWrap(true);
textArea.setWrapStyleWord(true);
textArea.setFont(new Font("courier", Font.PLAIN, 12));
scrollPane.setPreferredSize( new Dimension( 30, 100 ) );
String input = JOptionPane.showInputDialog(null, scrollPane, "Fun Chess ",
JOptionPane.YES_NO_OPTION);

This shows a nice text area and an input field underneath it.The getGameHistory() method just returns a long string detailing the current game.Is there a way of just showing the text area without the input field underneath?Can the text area also be used for input instead?

Compare User Input To Text File

Jun 6, 2014

I'm attempting to compare user input to a text file that I have set up whenever the user types in an employee ID number. I want to be able to tell the user that either the ID number is valid, or that it is not valid and must be re-entered by comparing it to the employee.txt file, and then record the valid ID number to the timeclock.txt file. I'm recording the next available employee ID number instead of the one I typed in. The output of the program looks like this: i82014/06/06 12:16:56 (I typed 1 as the employee ID.)

import java.text.*;
import java.util.*;
import java.io.*;
import java.nio.file.*;

public class TimeClockApp {
// declare class variables
private static EmployeeDAO employeeDAO = null;
private static Scanner sc = null;

Write User Input To Text File

Dec 8, 2014

I need to write a program where the user inputs name, age, email, and cell and write the user inputs to a text file. I need to have it so the file can be added to if more than one set of information is added. Currently, every time I click the button, the file is overwritten instead of added to. How do I correct this? Current code is as follows:

try
{
FileWriter writer = new FileWriter("ContactInformation.txt");
BufferedWriter bw = new BufferedWriter(writer);
nameTextField.write(bw);
bw.newLine();
ageTextField.write(bw);
bw.newLine();
emailTextField.write(bw);
bw.newLine();
cellTextField.write(bw);
bw.newLine();
bw.close();
nameTextField.setText("");
ageTextField.setText("");
emailTextField.setText("");
cellTextField.setText("");
nameTextField.requestFocus();
}
