How to display unicode values in file to corresponding characters

Hello Java-ians !
Could you please calrify my doubt ! I am able to generate unicode values for arbic, russian characters. I did it by generating a UTF-8 format file and I used native2ascii tool to generate unicode values. No I am unable to dispaly the characters. I read the file using FileReader and used JTextFiled.setText method to redisplay the characters. Instead of displaying the corresponding character, I am getting only unicode values. Why it's happening ?
Also could you plese tell me how ResourceBundle works ? It reads the unicode values and displays proper charcters, how ?
Please help me ! I need it desperately !
Martin Sunder Singh D.S.

you have to do like this:
FileInputStream fos = new FileInputStream(new File("japanies.out"));
BufferedReader bw = new BufferedReader(new InputStreamReader(fos,"UTF8"));
System.out.println(bw.readLine());
bw.close();

How to remove Unicode from XML file

I get following error when unmarshal xml:
[java] org.xml.sax.SAXParseException: An invalid XML character (Unicode: 0x15) was found in the element content of the document.
Anyone know how to remove Unicode from xml file? Can I remove the unicode by rebuild the file?
Thanks

These sort of error usually occur when you're using a different character encoding to read the file than the one you wrote it with. Perhaps if you were to post the problem section of the file and/or the code that created it in the first place.

How to display negative values in a screen field of a screen

Hi All,
Please let me know how to display negative values in a screen field of a screen.
thanks

Hi Kishore,
You can do this method. In the screen , create a text field of CHAR instead fo creating an INT4 field.
I have created a field of CHAR of name say TEXT.
In the main program,
declare a variable of the same name ie. TEXT.
data: TEXT(5) TYPE C.
In PBO, just assign the negative values.
It will work.Since there is automatic conversion between character and integer data types, it will work for positive values as well.

How to display korean text in file name

Hi, I want to know how to make my system recognize and display Korean text in file names and such. My mp3 files are all a bunch of gibberish and they display that way in the itunes as well; the title, artist, and everything else.
How can I fix this?

Thanks. I tried that but the application wouldn't save any of the files for some reason.
But it made me look for something else. In iTunes, I selected the song and right clicked, selected Convert ID3 Tags-->Reverse Unicode. Then it went to Chinese I think. I did the same thing again and it finally went to Korean.

Hi,
Add this line inside your run() method, right before your call to repaint():
if (image != null) {image.flush();}Hope this helps,

How to display(binding) values in the table from more than one node?

Hi,
I have two nodes (TRIPS & AMOUNTS)in the context. How to bind these values into the table control?
When i bind second one, first one is getting replaced.

Hi Mog,
Of course it is possible to create a table from attributes of more than one node, and in some cases this is still necessary, but you have to do this the hard (manual) way.
If you have a table control, have a look at the properties and the elements belonging to it.
First of all, there is the property "dataSource", which binds to a multiple node (let's name it TableRootNode). This means that for each element of THIS node, one row is created. In each row the data of exactly one element of this TableRootNode is displayed.
Then you have columns in this table. Inside of the columns there is a header and an editor. The editor is the interesting part.
Normally the primary property of this editor is bound to an attribute of the TableRootNode. Then everything works as expected. If it binds to an attribute of a subnode (SUB) of TableRootNode, then in row i the data of the subnode of the i-th element of TableRootNode is displayed. There is no need for SUB to be a multiple node, but it must not be a singleton.
If you bind a property of the editor to an attribute, which does not lie in the subtree of TableRootNode, then you will see the same value in each row.
Now it depends on the structure of your context. Take the node, which is relevant for the change in each row (I assume it is TRIPS) and bind the table to the node as you are used to. Then for each additional column, you have to create a new column in the tree, create a new header element with a title and a new editor (e.g. textview or inputfield) and then bind the right property of the editor to the corresponding attribute in node AMOUNTS).
If these 2 nodes do not have parent-child-relationship, the tip to create a new node, which consists of the attributes of both nodes is the only solution.
Ciao, Regina

How to display the values in JSpinner in format day:HH:mm

Hi All,
I want to know how can I display the values inside a JSpinner in the format day:HH:mm. Here the value of 'day' can be anything say from 0 to 365 and HH stand for hour and mm stands for minutes.
I tried to implement it using
mSpinner.setEditor(new JSpinner.DateEditor(mSpinner, "DD:HH:mm"));
but here the values of day was not proper. Please let me know if there is any standard format or how can I configure my own editor.
Thanks,
Rohit.

Hi,
It worked well for 112 as 112 comes under April month.. i.e. it will work properly for the range 91 to 120 as the current month is April and if we start counting from january 01 then for April month , the number of day will fall under range 91 to 120.
See, it will allow you to change the values beyond the limit (i.e. less than 91 or more than 120) but the real problem is that I used this spinner in the table and when I will try to save the value of spinner , then if the value of day in beyond the limit 91 to 120 then it will automatically changing in the range between 91 to 120.
I tried to use format DD:HH:mm ...... do I need to use any other format..
Hi All,
I want to know how can I display the values inside

I tried to implement it using

day 112 for today which seems correct.
