New line inside a JLabel
I know that this sounds like a noobie question but....
I created a JLabel that has a paragraph in it. When I run the program, it prints the paragraph in one line. How do I make it so I can insert new lines? Since this is a GUI, I can't use println. I've tried the following:
Code:
JLabel label = new JLabel("BLAH BLAH BLAH BLAH BLAH BLAH BLAH\n" +
"BLAH BLAH BLAH BLAH BLAH BLAH BLAH");
The "\n" doesn't work either. Help pl x?

Create an ASCII new line inside a variable?
I have
<cfset stringineed = varibale1 & "\n" & variable2 & "\n" & variable3 & "\n" & variable3>
I need "\n" to produce an ASCII new line but it doesn't. it just sends the actual \n characters.
This is not to be dispayed in an HTML page which of coruse I would use <br />
But instead it's to be sent to a coldfusion function which is why I need an ASCII new line.Dont you also have to put the chr(10)chr(13) in pound signs
for them to actually create the ascii character?
Not in the OP's case. Since the variables and functions are not enclosed in quotes, CF will recognize them as something that must be evaluated (not just plain text).
cfset x = variable1 & CHR(10) & variable2
But the real answer is "it depends". If that function were used inside quotes, you typically do need # signs. Otherwise CF will think chr(10) is just a plain string:
--- does not work ---
cfset x = "appleCHR(10)orange"
--- works ---
cfset x = "apple#CHR(10)#orange" -

How to insert a new line character inside CDATA tag in the source xml data file?
values for form fields in the xml data file is contained inside CDATA tags which is an Unparsed Format.
Eg: [CDATA[IBM-01 ~ DSHFSJDSJ ~ FGFGFJ, ~ VA 665665]] delimited by "~" char
Actual o/p:-
IBM-01 ~ DSHFSJDSJ ~ FGFGFJ, ~ VA 665665
Expected o/p is like :-
IBM-01
DSHFSJDSJ
FGFGFJ,
VA 665665
live cycle product does not interpret ~ as a newline character. Please suggest which character should be used instead inside CDATA section or if there is any other way to fix this?I do not have any problem while using IE's XML parser
for XML+XSLT merging.That is because IE's parser does not implement XML correctly.
But when I use JAXP's Transformer object, it does not
preserve the new lines inside attribute values and
converts those into white spaces.That is exactly what the XML specifications say should happen.
>
----If you have text that contains newlines, you
should put it in an element, not in
----an attribute.
That would be my last solution. But I'd really hate
to change my logic just 'coz JAXP is not capable of
handling new lines inside attribute values. I may be
wrong... but If IE can keep those then there has to
be a way to do the same from server side merging....Sure. Write your own parser with the same bug in it. But you don't have any right to demand that other people supply you with parsers that work incorrectly. -
Line in a JLabel that disappear when adding to a new frame

Can anyone helps me? Thanks ;)Hi again crwood!!
Okay, you're taking the content pane, a Container, from a top�level container (you mentioned a frame, "oldFrame"). And this container contains some JLabels which have lines drawn in them. You want to add this container to a card in a Cardlayout. Okay, so far so good.
That�s exactly what I want ;).
So (using your code):
I have the panel:
class SP extends JPanel {
private int x1;
private int y1;
private int x2;
private int y2;
private Color color;
private JLabel label;
public SP(int x1, int y1, int x2, int y2, Color c) {
this.x1 = x1;
this.y1 = y1;
this.x2 = x2;
this.y2 = y2;
color = c;
setLayout(new BorderLayout());
label =new JLabel();
add(label);
protected void paintComponent(Graphics g) {
super.paintComponent(g);
label.getGraphics().setColor(color);
label.getGraphics().drawLine(x1, y1, x2, y2);
public Dimension getPreferredSize() {
return new Dimension(300, 200);
}And the main frame:
public class SF extends JFrame {
private JPanel jPanel1;
public SF() {
// Initialize components.
jPanel1 = new JPanel(new CardLayout());
jPanel1.add(new SP(10,10,100,100,Color.red), "sample 1");
jPanel1.add(new SP(50,150,200,50,Color.blue), "sample 2");
JButton jButton1 = new JButton("OK");
jButton1.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent evt) {
CardLayout cl = (CardLayout)(jPanel1.getLayout());
cl.next(jPanel1);
JPanel south = new JPanel();
south.add(jButton1);
// Configuration and assemble JFrame.
setDefaultCloseOperation(EXIT_ON_CLOSE);
add(jPanel1); // Default center section.
add(south, "Last");
pack();
setLocation(200,200);
setVisible(true);
public static void main(String[] args) {
new SF();
}The problem is I cant see the black line...

I am having problems getting my strings into new lines with jlabels. I know i can do it with <html>...<br>...</html> but the string in the label changes. What is the best way of getting the strings on to mulitaple lines without spliting up words.
You can do whatever you want to the text area to make it look like a label:
setBackground(...);
setForeground(...);
setBorder(...);
setEditable(...);
Its all there in the API. -
I have a long string that contains couple of words, say 10 words. After every 3rd word i want to insert "\n" newline so that next string gets displayed in next line. Now if i display this final string in JLabel i expected there would be three lines displayed in Jlabel. But that doesnt work.
have you tried to use HTML? That just might work for
you.Oh thanks for the hint. I searched that in google and got this link. Thanks for the tips.

Records are not getting imported due to new line charactor in the field
Dear All,
I am trying to load a file into target but the import is failing. The error thrown is as below;
During the import of leads into CRMoD through loading the New lead/Step lead file received from CA, leads have not been imported and we encountered the following
error message:
"Import field 'LAST_NAME' had a blank value for the required Oracle CRM On Demand field 'Last Name'. This record was not imported. Please enter desired values for
the required fields and re-import this record."
Reason:
Leads are not imported due to an additional new line (Enter) character, which results in the subsequent lines not being picked up and the error of import failure.
Please help me to resolve this to remove the new line charactor in the field so that import succeeds..
By the way, I am working on ODI 11g.
Thanks in Advance
Regards
SantyWhile i was reading your post i remembered an issue that madded me. I don't know Oracle CRM, but a possible workaround could be to create a temporary Oracle table and load all data inside it. After that load in CRM only valid rows.

On my incoming messages, under my toolbars & above the msg header, is a new line. It sort-of looks like another toolbar, but different. It reads from left to right and each word is highlighted white:
Back Forward Refresh URL: ___________________ Go
Each of these words except for "URL:" are in boxes as if they are links but they don't work like links.
What is this and how do I get it off my incoming messages?
Thanks, nanciewandaI have no idea. Perhaps you could post the troubleshooting information so we can have a better look at what is going on.
Click the Help menu (Alt+H) and select ''Troubleshooting Information'' from the menu.

How to count number of lines inside methods() using the Doclet API
Wrote a custom doclet using the [Doclet API|http://java.sun.com/j2se/1.3/docs/tooldocs/javadoc/doclet/index.html ] .
The purpose for the doclet is to load Java source files and create stubs (which are identical Java source files but do not contain any method implementation details).
Instead, the method implementation details need to be replaced with blank lines...
public class MyDoclet {
private static String TAB = "\t";
public static boolean start(RootDoc root) {
ClassDoc[] classes = root.classes();
// Parse through class or interface
for (ClassDoc clazz : classes) {
Type superClass = clazz.superclassType();
// Print Methods
MethodDoc[] methods = clazz.methods();
for (MethodDoc method : methods) {
Parameter[] parameters = method.parameters();
println();
if (!method.isPrivate()) {
print(TAB + method.modifiers() + " "
+ method.returnType().simpleTypeName() + " " + method.name());
print("(");
for (int i=0; i < parameters.length; i++) {
Parameter parameter = (Parameter) parameters;
print(parameter.type().simpleTypeName() + " " + parameter.name());
if (i != parameters.length - 1) {
print(", ");
print(")");
println(" {");
println("\n");
println(TAB + "}");
return true;
As one can see, I am just creating the method and placing the opening and closing curly braces (along with a new \n line escape sequence, in between).
Am not really that familiar with the Doclet API...
Question(s):
(1) What is the best way to figure out how many lines of code are inside each method and then use a for loop to insert the exact same number of blank lines inside the methods?
(2) Is there a way to do it using the com.sun.javadoc.SourcePosition.line() method?
Would really appreciate it if someone could help me because this is an important requirement (hence the 10 Duke Stars).
Happy coding to all,
MikeThis is not possible using the Doclet API, because JavaDoc does not store any information regarding implementation detail. Although MethodDoc#position will give you the line where the method is declared, there is no way to determine where the method body starts and ends.
If you need that much information, maybe you would be better of using a tool such as Eclipse's Abstract Syntax Tree parser. AST will provide you with line numbers for each code expression, hence it is relatively easy to compute the first and last line in a method body. -
How to make new line in JButton.setText()?
how to make new line in JButton.setText()?
I want to set the text of jbutton in tow line ,as follows
| jbutton-line1 |
| xxxxxxx-line2 |
i konw i can jbtton.settext("<html>line1<br>line2</html>");
but i find it's ugly using html,
is there anyother way to create new line in JButton's TextAs for the above comment....
I thought the question was well purposed. Using HTML was not acceptable in this instance, which was made clear, so why critisize his comments? "Using HTML" is a poor solution, it does NOT work in many instances due to browser, OS variations. Usually the "common answer" is never a COMPLETE answer.
Possible Solution:
Use JLabels to render the text on the button.
import javax.swing.*;
import java.awt.*;
public class ButtonMaker {
public static void makeButton(JButton jb, String[] titleList) {
jb.setLayout(new FlowLayout());
for (int i = 0; i < titleList.length; i++) {
JLabel tmpLabel = new JLabel(titleList);
tmpLabel.setForeground(Color.black);
jb.add(tmpLabel);
public static void clearButton(JButton jb) {
Component[] cList = jb.getComponents();
for (int i = 0; i < cList.length; i++) {
if (cList[i] instanceof JLabel)
jb.remove(cList[i]);
Known Limitations:
1. Flowlayout does not work well with single line text buttons... perhaps another layout manager may work better for various buttonsizes-linenumber combos.
2. Mac OSX : The default UI for Mac OS X (and above it seems), is to have rounded edged buttons. These rounded edges are destoryed when using JLabels, leaving a square, blocky button in its place.
POSSIBLE SOLUTION:
(this is ugly and time consuming)
- create images of the button with text on them. -

Inserting new line to a text file at position #
Hi,.
Is it possible to do this in java?
1. Open a new text File (woutFile)
2. woutFile.write(" line #1\r\n"); // write new line
3. woutFile.write(" line #2\r\n"); // write new line
4.woutFile.write(" line #3\r\n"); // write new line
5. Go to line #2 position on a text file
6. Insert NEW LINE between line #2 and Line #3
7. move to the end-of-file
8.Close the file
Please helpIs it possible to do this? please look at question
inside comments.Your question has already been answered. Beyond that,
if you have some code and you want to know if it will
work, then run it and see.The answer was no. It's one of the fundamental properties of files that you cannot insert content in the middle, just at the end. To insert content you first have to make room for it. In this respect a file works like an array and not like a linked list. -

Writing to a new line in a text files
I have a servlet that collects results from a questionnaire by getting the parameter values of the radio buttons on a questionnaire page. I am trying to store the results of the questionnaire by writing them to a text file. I can get it to write to the files fine but cannot seem to get it to write the next set of results to a new line. I have many different ways but cannot seem to get it to work. Any ideas?
Heres the part of the code that writes to a text file
String lineRead = "";
int lineCount = 0;
while((lineRead = input.readLine()) != null)
lineCount ++;
String result = request.getParameter("question" + lineCount);
output.write(result + ",");
output.write("\n");Heres the part of the code that writes to a text
file
String lineRead = "";
int lineCount = 0;
while((lineRead = input.readLine()) !=
adLine()) != null)
lineCount ++;
String result =
String result = request.getParameter("question" +
lineCount);
output.write(result + ",");
output.write("\n");
Can you do output.writeln(result + ",");?
Failing that, putting output.write("\n") inside the while loop should do the trick.
