I used JTextPane to read logs which comes from telnet server. Problem is that when the new logs occurred and written to JTextPane, my selected text deselected I suppose that I should change default caret of JTextPane but I could not. Please give an any suggestion I want to preserve my selected text.
DefaultCaret caret=(DefaultCaret)theJTextPaneInstance.getCaret();
caret.setUpdatePolicy(DefaultCaret.NEVER_UPDATE);
You can switch off the update policy.

In my application I call an API to get the contents of the file as a String and use the TextArea UIWidget to display the file content to the user.
I want the user to be able to select the text in the text area in order to be able to copy and paste the contents of the file. When I hover over the TextArea in GWT, text selection is not being enabled. The getCursorPos function in the TextArea seems to be useful when modifying the textarea but not for selections
Text selection is enabled in TextArea by default. You either disabled it somewhere setEnabled(false), or you put another widget (panel) on top of your TextArea which prevents users from typing in or selecting a text.
I am creating a text editor using JTextPane that allows the user to bold, color and align the text by highlighting the text then selecting the option to either bold, color or align. After the adjustment is made, the selection goes away, but I want it to stay. Is there a way to get it to stay, or should I manually reselect the text? If so, how can I do that?
The example in Oracle's Java Tutorials does what you need and provides the source code.
In JFrame Form I have added a jTextArea and added a text into it, while still in design mode. But when I run the form I want the text to be invisible, which is not happening. I checked the properties of the JTextArea but I am not really sure how to change the visiblity of the text..
For clearing the JTextArea filed you need to set its text as empty.
For this you need to see JTextArea#setText as null or "".Try this code at the execution of your application.
jTerxtAreaObject.setText("");
Set the color of the text as the same color as the background.
I have JTextPane on my window and i have JTextField. When i press enter enter in JTextField, the text gets added in JTextPane. Everything works fine and scrollbar too appears on its own. But, it doesn't appear properly. It automatically scrolls to the beginning of the content in JTextPane. How do i keep the scrollbar to the end of JTextPane?
The provided link in the accepted answer is an old link. You may want to check out Text Area Scrolling for additional information. The entry is for a text area but I believe the information applies to a text pane as well.
You can try by invoking
scrollPane.scrollRectToVisible(new Rectangle(0,main.getBounds(null).height,1,1));
This should be the most working approach. Otherwise try to search out scrollPane.setValue(..) or work with the caret: editorPane.setCaretPosition(...)
I found a discussion of the same problem. Have a look at http://www.coderanch.com/t/329964/GUI/java/JScrollpane-Force-autoscroll-bottom
I have a jtextarea that is not editable. It has some text in it. What i want is that when a user clicks in the jtextarea, (preferably single click), the entire line be highlighted, and this highlighted text be retrieved.
Each line actually has an email of the form name#emailid.com. To select the entire text would require triple clicks. I want the email to be selected in a single click. Is this possible?
Sure. Just implement you own listener and call http://java.sun.com/javase/6/docs/api/javax/swing/text/JTextComponent.html#select%28int,%20int%29 on the JTextArea.
But wouldn't a JList not rather fit your requirements?
