JSP :: JSTL Code To Fetch Text Field Values Dynamically
Apr 16, 2014
I am generating textfields dynamically using JSTL forEach. Here is the code ..
<c:forEach var="underlyingTickers" items="${underlyingTickersList}" >
<tr>
<td ><input name="underlyingTickers" type="text" id = "underlyingTickers" value="<c:out value='${underlyingTickers}' />">
</td>
</tr>
</c:forEach>
If there are 4 values in underlyingTickersList A, B C, D and E ... I am getting those values correctly displayed in each text field.
However if I submit the form with all these value how can I get it in the bean? I guess I need to have dynamic id or name for each text field. How can generate it?
Note** I dont have Struts framework.. I am using request.getParameter to fetch the values and set into the bean variable.

I need to fetch the values inside the tag/node of an XML file.
The xml.file looks like this,
<numeric_values>
<data cc="100" ln="58">2291</data>
<data cc="100" ln="59">2291</data>
<data cc="105" ln="58">2389</data>
<data cc="105" ln="59">2389</data>
<data cc="110" ln="59">1</data>
<data cc="110" ln="57">1</data>
[Code]...
I need the value of cc and ln.
For example the first line contains cc = 100 and i need to fetch 100 and ln = 58 and i need the value 58.

I'm supposed to write a GUI application letting the user enter a file on the text field and display its hex representation in a text area and vice versa.
Here's my code:
/*

* and open the template in the editor.
*/
package hexconvertor;
import java.util.*;
import java.io.*;
public class HexConvertor extends javax.swing.JFrame {

It's not doing anything, I don't understand why.

I have a textField in which I have text in. The text is enter customer name. I would like for this text to disappear whenever the user clicks on the textField to enter a customer name. I am using the automated swing gui builder in NetBeans. Is their some sort of feature for this under properties of the text field? If not then what are my other options?

I have a PDF file and I have a text file that contains this data. It has the name of a PDF field along with a database table column name.
Text file: pdfFieldEmployee=Employee; pdfFieldStartDate=StartDate; pdfFieldSalary=Salary; pdfFieldExempt=Exempt
I also have this hash map that contains the database table column names along with their corresponding values:
Employee, Don Parker
StartDate, 5/6/2000
Salary, $55000
Exempt, N
How would I read through the text file and the hash map and at the same time do this:
if the pdf field is equal to pdfFieldEmployee, then set pdfFieldEmployee equal to Don Parker.
if the pdf field is equal to pdfFieldStartDate, then set pdfFieldStartDate equal to 5/6/2000.
and so on and so on. I would prefer to do this with a loop because I think it would take less code than writing a bunch of if statements.

ResourceBundle messages = ResourceBundle.getBundle(Constants.messageBundle, currentLocale);
messages = Panel.getMessages();
String displayString = messages.getString("101022");

I have a requirement where in the content of the text area is dynamically populated from the database. I am able to successfully retrieve and display the data on the text area.
However when the content is too large, I am not able to dynamically set the height of the text area. When I try to display the same as a label, the display is flawless, dynamically sets the height as per the content. So, I tried to create a label, with same content and dynamically bind the height to the preferred height as below, but it doesn't work.
// Generate User Note Description
TextArea textArea = new TextArea();
Label text = new Label();
// SETTING THE TEXT TO A LABEL TO RETRIEVE THE HEIGHT
text.setText(usrNotes.getNote().trim());

i need to develop a java program in which it will ask the user "Username" and "Password" and by which it will login to a wesite.
I have developed a GUI in which the username should be entered in the User "JTextfield" and Password in Password "JPasswordField". I need to make sure that password should not be displayed in the GUI. but I didnt find a way to parse the string (char) entered in the "JPasswordField" to the website.
It is always passing a 'null' character! I tried to search in internet and i found that it wont be able to pass the passwordfield characters but you will be able to check in the main function itself by comparing with another char array in the main program itself whether the password entered is correct or not.
Is there any alternate way for this?
Objective : Parse the password (which is not displayed in the GUI) to a website or some other function where it will use it

I have a question about JTextArea colors. When i set the color to blue and then write something on the JTextArea (JTextArea.append) and then set it back to black everything will be black. How can i solve that? Like in Notepad++ or Eclipse when you write keywords in a JTextArea (where you write your code) only some words change color.
This is my code:
// All the imports
public class whatever extends JFrame {
JTextArea a = new JTextArea();
public whatever() {
super("Title");
add(a);
[code]...

I'm trying to figure out a good way to allow my users to have some formatting options within a text box in my application. Ultimately, they need to be able to have text that is alternating between two separate fonts, and ideally could have both italicized and bolded words as well.

I am using JSTL library in my jsp. Previously, I was directly printing the text in JSP without using JSTL and it was printing fine.
My text is : Server Down, can't perform operation.
I was getting this error message from my backend code and was able to print this successfully. However, after using JSTL, doing like this:
pageContext.setAttribute("error", someObject.getError());
<c:out value="${error}" />
Here, c refers to <%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
This is now printing the encoded form of the apostrophe char : Server Down, can't perform operation.

So basically I have this alpha.dat file which stores data submitted when I execute the alpha class and here I have a AWT textfield which reads a password from user. I have another class called beta and I have another AWT textfield in it which also reads the same password from user. How do I compare both passwords?(I know I need both classes to refer to alpha.dat but how do I compare both textfields in different classes)

I want to use this class and method with all of my buttons and text fields. My program contains 1 push button that adds questions and answers to a test, 2nd button that starts a test, a 3rd button that scores the test, and a text field that enters the user information. How would this work? I know how to create questions and answers, start a test, and score a test it's just a matter of how to implement the button and text fields. I'll post the code that I have done so far.
See:
private class ButtonListener implements ActionListener{
public void actionPerformed (ActionEvent event)
with all of my buttons and text fields.
import javax.swing.JFrame;
public class TestingDriver
{
//-----------------------------------------------------------------
// Creates and displays the main program frame.
//-----------------------------------------------------------------
public static void main (String[] args) {
JFrame frame = new JFrame ("Testing Program");
frame.setDefaultCloseOperation (JFrame.EXIT_ON_CLOSE);

In my application, some text should be added to a text area in response to a click on a button. So as an action listener to this class, I made another class which implements the ActionListener.
Inside this class, I have obtained the text which I want to be added to the text area. But the text area is in another class and for the action listener I wrote another class.
Now the problem is that when I try to add the text to the text area by the following line of code, it says that textArea_1 can not be resolved or is not a field.
Java Code:
ParentPanel.textArea_1.setText("Name:"+ncrarray[0]+"
Code:"+ncrarray[1]+"
Rank:"+ncrarray[2]); mh_sh_highlight_all('java'); What should I do about it?
Even if I try to write a method like the following in the class in which the text area is created, it gives the same error.
Java Code:
public void printTextArea(String text) {
textArea_1.setText(text);
} mh_sh_highlight_all('java');
The text area is present inside a constructor of the class. I am writing the method outside the constructor (ofcourse).
