JTextField(Document, string, int)
Dear friends,
Could you just tell me how can I fix the size of the JTextField,
such as just accept the maximum number of digits or characters in JTextField...
I cant create the Document....
Could anyone give me a tips?
I found the best way to do this is to subclass PlainDocument as follows:
public class MyTextDoc extends PlainDocument
int maxCharacters;
public MyTextDoc(int maxChars) {
maxCharacters = maxChars;
public void insertString( int offs, String str, AttributeSet a )
throws BadLocationException {
if( (getLength() + str.length()) <= maxCharacters)
super.insertString(offs, str, a);
else
Toolkit.getDefaultToolkit().beep();
}I then use this document in the constructor for all my JTextFields.
I'm not sure what you mean by "I cant create the Document...."
Cheers
Gary

Checking if input into JTextField is an int value
Is there any way that you can check whether the String entered into a JTextField represents an int?
Thanks for the help!

Hi,
I have this few lines :
JLabel LNSociete = new JLabel( "Nom ");
LNSociete.setBounds(160,5,100,20);
c.add(LNSociete);
INSociete = new JTextField();
INSociete.setBounds(210,5,150,20);
c.add(INSociete);
LNSociete.setLabelFor( INSociete);
NICC = INSociete.getText();
my NICC is define as : String NICC = new String();
and INSociete as a JTextField
When I'm looking in my frame I have a name in the INSociete fields.
I WANT receive the text in my NICC I saw or I modified in my frame, but I have " " in my NICC string.
regards
ThierryAs Kamran said, you will need a listener to get the text.
You have written the code to set up the component but accessing the text must be event driven. As written, your code to get the text happens immediately after the textfield is setup so the user doesn't have time to enter the text before you try to get it out.
When the user enters the text (and hits return, unless you are using a focuslost listener that hears when the component loses focus or a document listener that hears every keystroke) then an event is triggered that you can write a listener to handle. The listener code then can get the text into NICC.
I suggest you have a look at the swing tutorial for text components, especially: http://java.sun.com/docs/books/tutorial/uiswing/components/simpletext.html#textfield
has an example action listener (user has to hit return to triger an action event on a textfield).
Hope that helps,

From JTextField into string array
hello,
Me and my friend are currently doing a cryptography project for UNI. We are required to read in a word from the JTextField into an array. the problem is the whole word seems to be going into the array as one element. Is there any way to read in each letter in the word into a seperate element of the array??Well you can always read the value in the textfield, convert it to a character array and then as you transfer each character to your string array you add a blank string to it, so then it becomes a string.
Example:
String sentence = "hello, I am a really loooooooooong string";
String[] stringArray = new String[sentence.length()];
char[] charArray = sentence.toCharArray();
for (int count = 0; count < sentence.length(); count++)
stringArray[count] = charArray[count] + "";I hope this helps. -
Hi
Can anyone tell me how i can extract the text i entered in a JTextField to a String?

Namespace prefix in created DOM document string
Hello world,
I am creating a DOM document using the standard JAXP APIs. The document is not parsed from anywhere, just created using the DOM API factory methods. This document is a SOAP message with the SOAP envelope, header and body elements. Now I need to have this document transformed to an XML string.
I can manage all this. However, I want to have the SOAP namespace set for the SOAP elements, and I want it set using a prefix (such as "SOAP-ENV" or "env" as in the example below). I have set the envelope, header and body element namespaces to the soap namespace. The rest of the elements inside header and body I have set to null namespace. I want them without any prefix (and what namespace will that be then, default?).
The problem is, when I transform the document to a string, the namespace is set on the envelope without a prefix, and not on the header or body. I guess this is because the child elements will all inherit the namespace? I tried with xalan and saxon.
Here is an example of output that would look like what I want:
<env:Envelope xmlns:env="http://www.w3.org/2002/12/soap-envelope">
<env:Header>
<foo>hello</foo>
</env:Header>
<env:Body>
<bar>is open</bar>
</env:Body>
</env:Envelope>Here is an example of output that looks like what I got:
<Envelope xmlns="http://www.w3.org/2002/12/soap-envelope">
<Header>
<foo>hello</foo>
</Header>
<Body>
<bar>is open</bar>
</body>
</Envelope>So so what am I doing wrong, how should I do it? If my rambling makes no sense, even an example of constructing output like the example of what I want would solve this.. :)
Thanks,You could just create the an attribute like this:
root.setAttribute("xmlns:env", "http://www.w3.org/2002/12/soap-envelope"); where root is the Envelope element.

I have a problem with using a JTextField in an IF statement. What im trying to achieve is that when the variable "TOLASuser" (JTextField) has a blank text (null) the IF statement then goes on to tell the user through a JTextArea that a null entry is not valid. The problem i'm having is that the IF statement does not read the TOLASuser.getText() as null when there is nothing entered into it, and goes straight on to the else clause.
Do I need to add anything additional to the code prior to using the IF statement. Below is my code.
This is only a small simple program if the entire source code is required I can provide it.
private void BtnValidateActionPerformed(java.awt.event.ActionEvent evt) {
ConsoleView.append(TOLASuser.getText() + '\n');
String User = TOLASuser.getText();
if(User == null)
ConsoleView.setForeground(Color.red);
ConsoleView.append("You must enter your TOLAS username");
else
LblInputpath.setText("\\" + "\\adrsydtolastest\\TOL_USR_DIR\\" + TOLASuser.getText() + "\\RUN\\DTOPLAB.txt");
LblOutputpath.setText("\\" + "\\adrsydtolastest\\PAST_IN_RDY\\" + "TO891.CAF");
ConsoleView.setForeground(Color.red);
ConsoleView.append("PLEASE CHECK THE INPUT AND OUTPUT PATH BEFORE EXECUTING" + '\n');
BtnGo.setEnabled(true);
}Thank you very much for you help. the use of a new string variable initialised as "" and the use of the equals() methods works perfectly.
below is my new code. not that you need to see it, i just want to make sure i used the CODE tags properly.
Thanks again.
private void BtnValidateActionPerformed(java.awt.event.ActionEvent evt) {
String Varify = "";
String User = TOLASuser.getText();
if(User.equals(Varify))
ConsoleView.setForeground(Color.red);
ConsoleView.append("You must enter your TOLAS username");
else
LblInputpath.setText("\\" "\\adrsydtolastest\\TOL_USR_DIR\\" TOLASuser.getText() "\\RUN\\DTOPLAB.txt");
LblOutputpath.setText("\\" "\\adrsydtolastest\\PAST_IN_RDY\\" "TO891.CAF");

Hi,
i'm building a webapp to simply allow the user to enter his or her details which will be submitted with all the details stored in the bean. When deciding to either make properties such as age or telephone number as string or int in a bean, i read somewhere that it is a rule of phumb to set these properties as Strings as they are easier to validate. If that is the case, if i create a property of String age with it's corresponding getter and setter method i.e
public void setAge(String n) {
age = n ;
public String getAge()
return age;
doing something like the above would not convert the value into an int which is what i would like to do. Therefore, i was thinking of doing the following in my bean class:
package beans ;
public class Person
private int age ;
// Constructor
public Person() {
age = 0 ;
public void setAge(int n) {
age = n ;
public void setAge(String s) {
try {
age = Integer.parseInt(s) ;
catch (NumberFormatException e) {}
public int getAge() {
return age ;
}doing the above would i think be more convenient. Would that be the better way do you think?

I've seen my example duplicated in many exampls and in books. I'm not to concerned if it has to be duplicated in every bean and int, it's not what i was asking.
In terms of the fomatting errors, what errors? Do i need to correct something?
Thanks for your input raychen.

I'm sure this sort of thing has been asked but i cant find it in the forums.... I'm trying to read in a string from a form and then convert it to an int so that i can use it in a select statement so i can compare it to a field declared as "Number" in the Access Database.
String sess = request.getParameter("num"); //num comes from form
int eventNum = Integer.parseInt(sess);
//connected ot the database
String query = "SELECT * FROM EVENT WHERE event_id = 'eventNum' ";
ResultSet result = stmt.executeQuery(query);
//event_id is a number in the database
Its saying "Data type mismatch in criteria expression"
Thanking you in advance,
BrianSince you are building a string as query, you don't need to convert it
String sess = request.getParameter("num"); //num
String query = "SELECT * FROM EVENT WHERE event_id ='eventNum' ";
ResultSet result = stmt.executeQuery(query);This error "Data type mismatch in criteria" comes from event_id = 'num'
event_id is numeric, so it should not contain quotes in the sql statement
this will do it:
String query = "SELECT * FROM EVENT WHERE event_id =" + sess -
i want to convert a string var into int var?
how is that possible in jsp?
thank you!int intvar = Integer.parseInt(StringVar);

Sending more than one original document via INT
Hi all,
I've created a DIR with 2 Original Documents uploaded in.
When I start the distribution (Distribution type --> INT) I receive the e-mail without any attachment.
Otherwise, if I upload a single original document in the DIR, I get the correct e-mail (with the attachment).
Suggestions?
Thanks,
Marco.

Hi,
I have a JTextField field, which is supposed to be read only field to show time.
My application gets from server a long value, which represents the time.
This JTextField field shows the time (from server) in format mm:hh:ss (need to convert the long value to the format).
My question is:
Which document model should I use and how? I don't find a good example for that.

JTextField Document validation
What is the best way to use Document to validate a textfield that will only accepts numbers between 1 and 30.
Lets say there is a situation where we really need to prevent users from typing numbers out of range (instead of showing an error message afterwards). I looked at the tutorial and there is an example on how to use DocumentFilter to restrict input to Integers. I tried to adapt it to do range checking. I was successful in enforcing max value but I can't get it to enforce min value. If the min value is 2 and if the user types 11 then DocumentFilter.insertString is called twice. First with just 1 and then with 11. Is there someway to stop insertString from being called until the user is done typing? I must be missing something obious.
