Set text of jtextArea to a text file

I have tried everything in trying to let the user select a text file using jfilechooser and then set the text of a jtextArea as the text file. Nothing has worked so far, so all I have right here is the basic functionality of choosing the file.
If someone could show me a good way to read the whole text file and put that text into a jtextArea, I would really appreciate it.
Since nothing has worked all I have is this:
JFileChooser chooser = new JFileChooser();
int returnVal = chooser.showOpenDialog(this);
String getFile = chooser.getSelectedFile().getPath();

... followed by theJTextArea.read(new FileReader(getFile), null);

How do you read data from a text file into a JTextArea?

I'm working on a blogging program and I need to add data from a text file named messages.txt into a JTextArea named messages. How do I go about doing this?

Student_Coder wrote:
1) Read the file messages.txt into a String
2) Initialize messages with the String as the textSwing text components are designed to use Unix-style linefeeds (\n) as line separators. If the text file happens to use a different style, like DOS's carriage-return+linefeed (\r\n), it needs to be converted. The read() method does that, and it saves the info about the line separator style in the Document so the write() method can re-convert it.

Neither of those methods applies to JTextAreas.

Set a timeout for "read from text file"

I Need to read from a text file on a remote pc and use the read from text file function to do this. It wotks but sometimes this pc is down causing long wait times in my vi.
Is there a way to set a timeout for the read from text file function, or is there an other solution?
Thank you

You could check that the path is valid first before you attempt to read the file. hen put the file read in a True-False case structure based on the results of the check. You can use the function "Check if File or Folder Exists" It checks whether a file or folder exists on disk at a specified path. This VI works with standard files and folders as well as files in LLB files. The function is found in the File I/O --> Advanced File Functions palette.

File adapter-How to set line break in text file-split record into two lines

Dear Guru's,
I have to solve following problem with XML (with mulitiple records) to TEXT file scenario using file adapter. I have to output for ever ONE data record in XML always two identical lines in text file. Second line should have a little bit different mapping in few fields like date,... So I did duplicate fileds in my output structure in mapping and need to know how to set line break in the middle and see half of structure in first line and next structure half in second line
My output structure in mapping is:
CASHFLOW
- INTERFACE
- GESELLSCHAFT
- ANWENDUNG
- PRODUKT
- VERTRAG
- BETRAG
- WAEHRUNG
- DIRECTION
- BEWEGUNGSTYP
- FAELLIGKEIT
- ZINSFESTSTELLUNG
- ZAHLUNGSTAG
- RENDITE
- INTERFACE2
- GESELLSCHAFT2
- ANWENDUNG2
- PRODUKT2
- VERTRAG2
- BETRAG2
- WAEHRUNG2
- DIRECTION2
- BEWEGUNGSTYP2
- FAELLIGKEIT2
- ZINSFESTSTELLUNG2
- ZAHLUNGSTAG2
- RENDITE2
Question is how can I set on receiving file adapter in Content Conversion Parameters that fields from first structure half INTERFACE...RENDITE should be outputed in one line and fields from second half of structure INTERFACE2...RENDITE2 should start on second line in final text file.
I'm getting at the moment one line only and I need to know how can set line break so that second line starting with INTERFACE2(CA)...RENDITE2 will start in new line.
CA,"0100","7","512",20090127010001,-12454762586.6800,"EUR",2,12,2009-01-28,2009-01-27,2009-01-28,"0.0000000",CA,"0100","7","512",20090127010001,-12454762586.6800,"EUR",1,10,2009-01-27,2009-01-27,2009-01-27,"0.0000000"
This should be final output:
CA,"0100","7","512",20090127010001,-12454762586.6800,"EUR",2,12,2009-01-28,2009-01-27,2009-01-28,"0.0000000"
CA,"0100","7","512",20090127010001,-12454762586.6800,"EUR",1,10,2009-01-27,2009-01-27,2009-01-27,"0.0000000"
My file adapter settings:
RecordsetStructure=CASHFLOW
CASHFLOW.fieldNames=INTERFACE,GESELLSCHAFT,ANWENDUNG,PRODUKT,VERTRAG,BETRAG,WAEHRUNG,DIRECTION,BEWEGUNGSTYP,FAELLIGKEIT,ZINSFESTSTELLUNG,ZAHLUNGSTAG,RENDITE
CASHFLOW.fieldSeparator=,
CASHFLOW.endSeparator='nl'
CASHFLOW.fieldNames=INTERFACE2,GESELLSCHAFT2,ANWENDUNG2,PRODUKT2,VERTRAG2,BETRAG2,WAEHRUNG2,DIRECTION2,BEWEGUNGSTYP2,FAELLIGKEIT2,ZINSFESTSTELLUNG2,ZAHLUNGSTAG2,RENDITE2
CASHFLOW.fieldSeparator=,
It wont help if I add two identical structures in mapping because in output i would see for multiple entries section with first lines only and after that section with second lines only. And CASHFLOW is one part of more complex mapping ...
(This is final output structure RecordsetStructure=HEADER,CASHFLOW,CONDITION,REFERENCE,CONTRACT - more sections with different data and all these should have duplicate lines at the end)
Thanks a lot for any help
Cheers
Marian

Hi Ivan,
right, I did test just for sure.
Putting constant 'nl' into field CASHFLOW-INTERFACE1 didnt help - still getting one line instead two lines.
CA ,"0100" ,"7" ,"512" ,20090127GTP101 ,-12454762586.6800 ,"EUR" ,2 ,12 ,2009-01-28 ,2009-01-27 ,2009-01-28 ,"0.0000000" ,'nl' ,"GTP1" ,"7" ,"512" ,20090127GTP101 ,-12454762586.6800 ,"EUR" ,1 ,10 ,2009-01-27 ,2009-01-27 ,2009-01-27 ,"0.0000000"
So there is still question. Is there any way (mapping,...) how to output always 2 lines in text file for one record in XML. It always does 1 record in mapping structure = 1 line but we need 2 lines ...
Example:
Input: 4 records in XML
Output: 8 lines in final text file ...
Thanks to you all guys

Dynamic Distribution Group set conditions by importing text file?

Exchange 2010 SP2.
I created a dynamic distribution group via the EMC. We have populated AD with ExtenstionAttribute1 and ExtensionAttribute2. I have created the ddg with custom attribute1 value = employee. What I need to do now is populate custom attribute
2 = 00-0001, 00-0002, and so on. There are about 300 of these numbers I need to add. I have them in a text file or csv file. Instead of adding them one by one in the EMC, is there a way to import them via powershell to the existing ddg?
The ddg is called All Management Employees.

If they go from 00-0001 to 00-0300, you could just add them as follows:
Set-DynamicDistributionGroup <group name> -RecipientFilter "(CustomAttribute1 -eq 'employee') -and (CustomAttribute2 -like '00-0*')"
However, if you have additional items like this (such as 00-0350, etc), you may need to use the following:
Set-DynamicDistributionGroup <group name> -RecipientFilter "(CustomAttribute1 -eq 'employee') -and ((CustomAttribute2 -like '00-00*') -or (CustomAttribute2 -like '00-01*') -or (CustomAttribute2 -like '00-02*') -or (CustomAttribute2 -eq '00-00300')"
Now, if your numbering isn't sequential and it can't be, you would need to add them individually - which may make your search filter unusable, in which case, you may need to create several dynamic groups and add them to a parent group.

Dim p_AcroApp As CAcroApp
Dim p_VDoc As CAcroAVDoc
Dim p_DDoc As CAcroPDDoc
Dim IsOk As Boolean
Set p_AcroApp = CreateObject("AcroExch.App")
Set p_VDoc = CreateObject("AcroExch.AVDoc")
Call p_VDoc.Open(srcFilename, "")
Set p_VDoc = p_AcroApp.GetActiveDoc
If p_VDoc.IsValid Then
Set p_DDoc = p_VDoc.GetPDDoc
' Fill in pdf properties.
p_DDoc.SetInfo "Title", Format(Date, "dd-mm-yyy")
p_DDoc.SetInfo "Subject", srcFilename

1) to be able to set the font face of the destination file ( destFilename)
2) to be able to set the font size of the destination file ( destFilename)
Am using Adobe Acrobat 7.0 Type Library
Kindly Help.
Thanks in advance

We didn't say it doesn't work. We said it isn't supported.
There are a number of other ways to make a PDF. The one which would
give the most control is if your application directly printed to GDI,
controlling the font directly. This could print to Adobe PDF.
You could look for an application that gives control of font for
printing.
You could use a text-to-PostScript system and distill the result. You
could even look for a non-Adobe text-to-PDF.
Working in the unsupported and dangerous world you chose, the font
size for text conversion is set (and this is very bad design from
Adobe) in the settings for Create PDF > From Web Page. There is no API
to this.

Why does saving text from a jtextarea to a text file result in....?

one long string that includes square blocks when the new line should be?
Why can't I read normal text from a text file. It looks like i have to save it first for it to be read.
Also why is it that my application succesfully reads and displays the contents of a text file that i just saved but when i manually open that file I don't see it. All i can see is what the text that i manually entered into the text file.
I use a buffered reader so wondered if there was some caching but have no idea.

one long string that includes square blocks when the new line should be? If you use something like:
write(textArea.getText())
then "\n" will be written to the file as a newline string, but on a Windows platform the newline string is "\r\n".
You should be using the read(...) and write(...) methods of the JTextArea and the newline string will be handled correctly.

Reading in Latin Extended-A character set from a text file

Hello all,
I am writing a small program that reads in a text file containing special characters (beyond the ASCII char set) and converting it into "regular" characters. For example I would read in a uaccent and replace it with a u.
Now I realize that Unicode support is built into Java from ground up but it goes only so far, you actually have to have the relevant character set to read it. My code is as follows:
InputStreamReader inStreamReader = new InputStreamReader(new FileInputStream("input.txt"), "ISO-8859-1");
BufferedReader bufferedReader = new BufferedReader(inStreamReader);
String line = null;
StringBuffer buff = new StringBuffer();
while((line = bufferedReader.readLine()) != null) {
char[] charArray = line.toCharArray();
for(int i = 0; i < charArray.length; i++) {
int x = (int)charArray;
switch(x) {
case 224: // this is agrave .. we need to replace it with a
buff.append('a');
break;
case 230: // this is aelig .. we need to replace it with ae
buff.append("ae");
break;
///////// and so on
Since I am reading in as ISO-8859-1, this works up to unicode 255. For the rest of the characters, apparently I need a Latin Extended-A and Latin Extended-B character set. How can I get that installed on my Windows OS machine? I am using jdk 1.4.1 on Windows XP. Any help is appreciated.
Thanks,

Any help is appreciated.If your file has characters outside of 8859-1's range (0 - 255), then it isn't ISO-8859-1 encoded. You need to know what encoding was used to store the file. It sounds like you it actually may be Unicode text, in which case you need to know which encoding (UTF8, UTF16, etc) was used.

How to redirect "-verbose" Java Runtime Parameter setting to text file

Simple question: I am adding a "-verbose" Java Runtime Parameter in the Java Applet Runtime Settings of the Java Control Panel. When I run my applet, a Windows console opens which outputs all the method calls, classes, and jar file information. How can I redirect this output to a text file?
I noticed Xloggc:+filename+ but there does not seem to be an equivalent for redirecting the '-verbose' output to a file.
Thanks!
Edited by: zillius on Dec 14, 2007 1:47 PM

Thank you both for the reply, but unfortunately that is not quite what I am looking for. The console Window I am talking about is a DOS console screen, not the Java Console
What I am really after here is the ability to redirect a thread dump of a running applet to a text file. When the applet is active, and the "-verbose" parameter is set in the Java Runtime Parameters", I can see all the classes, methods etc. being loaded in the DOS window. Hitting Ctrl-Break at that point will produce a thread dump in the DOS console screen. I would like to be able to redirect THAT output to a text file. It is not in the Java Console. To me it looks like tracing and logging are only for the Java Console, no?
Thanks again for your help.

Text file will only print one set of input and puts in end for name.

Okay, I have this more or less straightened out. Only thing is, it creates the text file, and will only enter one set of data. It will not print the other students information to the text file. The other thing it does is puts in the student name as end. I think that has something to do with the fact that I need to compare the student name field (SName) to end, so the program can be ended. Anyone have some ideas? I have been working on this for almost 2 weeks, and am about ready to throw the computer off a cliff..
Thanks.

Not 100% sure this is what you're after, but it seems to work OK
