Swing/AWT/SWT :: Reading From HTMLEditorKit Doesn't Display Text While In Text / HTML Content Type?
Apr 24, 2015I'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?

View Replies View RelatedServlets :: Shopping Cart - Show Text Based On Which Page A User Is Coming From
May 30, 2014I am making a shopping cart app in JSP and servlets to bring it all together. Finally.
I have a registration servlet (c1), a registration form jsp (c2), a login jsp (c3). c1 checks if a username is in the database or not.
If the username is not there, then register the user and send them to c3. I want c3 to display a "registration successful" message if a user has just registered successfully and is coming from c1. ELSE, take the user back to c2 with a message which tells them to choose a different username or password etc.
How do I implement the logic of showing a message depending on where a user is coming from ? The servlets and jsps are ready and I only need to add this logic for a custom message. Of course, I could make a JSP for Registration Successful and one for Registration Failure. But, that seems to be unnecessary.

Identifying File Type By Reading Its Content
Oct 27, 2014Is there a way of detecting the file's type (whether it is a pdf, jpg, png,or anything else) by reading the content of the file. We could read the extension of file to determine it's type, but then extensions can be forged too. So I would like to know if the content inside a file is of a particular type or not. I'm not sure about this, but I have heard somewhere about each having having a specific kind of header which determines its type. So is it possible to read that header and determine it using a program?
View Replies View RelatedDouble Data Type Outputting To Exponent?
Nov 9, 2014I was struggling to use BufferedReader to extract some data and then perform some calculations and then have the results as outputs.
I haven't quite solved that issue but in order to progress, I hard coded some values into my application and proceeded with the actual calculation loops etc.
Currently, the value out put from one of my calculations is given as:
1.1704926E7
How can I make the console show it in a natural way. I've performed the calculation manually and it should be 11704926.5 I don't want to lose that .5!
Unable To Use Double Data Type In For Loop
Aug 12, 2014I am trying to use double data type in a for loop for precise operations and just to see if there could be any problem doing that I tested a small code :
public class doubleLimit {
public static void main(String[] args){
for(double i=-0.1;i<=0;i+=0.01)
System.out.println(i); }}
The output I was expecting is :
-0.1
-0.09
-0.08
-0.07
-0.06
-0.05
-0.04
-0.03
-0.02
-0.01
0.00
But the output of the code is :
-0.1
-0.09000000000000001
-0.08000000000000002
-0.07000000000000002
-0.06000000000000002
-0.05000000000000002
-0.040000000000000015
-0.030000000000000013
-0.02000000000000001
-0.01000000000000001
-1.0408340855860843E-17
Why is the code not working the way I expected, I think it has something to do with any property of double but I am not sure.

For Loop Program - Increment Hours By 12 And Double Population By 2 Each Time
Oct 3, 2014So I need to make a for loop for this problem: A certain type of bacteria doubles its population every twelve hours. If you start with a population of 1000, how many hours will it take for the population to exceed 1,000,000? Output needs to be in table format, such as:
Hours: - Population:

int population;

Apr 8, 2014I 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.
