How to get InputStream from a file with absolute path?

Hi, guys:
If I have file with a absolute path that may be inside/outside
my Eclipse plugin, I want to get an InputStream from it. It just keeps giving me null for "is":
String absFilePath = "/D:/my_dir/.../sample_file.txt";
InputStream is = getClass().getResourceAsStream(absFilePath);
regards,

Don't use resource as stream if you have an absolute path, use FileInputStream.

How to get InputStream of uploaded file from request?

The situation:
Client is uploading xml file to server.
<form METHOD=POST ENCTYPE = "multipart/form-data" action="SendFile" accept="text/xml">
<input type="file" name="SentFile" />
<input type="submit" value="go"/>
</form>Then I need to parse data from file.
I want to use method javax.xml.parsers.DocumentBuilder.parse(InputStream is)
But, how to get InputStream of uploaded file from request?

You cannot get the InputStream of the uploaded file directly. The InputStream you can obtain from request.getInputStream() contains a lot of other data as well as the uploaded file. You will have to parse the data in the InputStream to find the data that belongs to the file.
A short cut is to use the HTTP Multipart File Upload available from www.jenkov.com. It simplifies file upload and makes it easy to obtain an InputStream for only the uploaded file. It also handles upload of multiple files. It is free, open source, Apache license, so if it doesn't fit your needs, you can always read the code and see how it works. Then write your own upload servlet.

How to get data from a file?

Hello everyone, i'm new to this forum and to java too. Ok, so here is what i want to do:
I want to get data from a file containing words and numbers and store them into variables that i will use them after to insert into a database table. For example i have a file called employees.txt in this form:
eid ename zipcode Hire_date
1000 "Jones" 67226 "12-DEC-95"
In C++ i declare variables for each data and store them, for example in this case:
ifstream in("somefile");
string name, hdate;
int eid, zip;
in >> eid >> ename >> zip >> hdate;
So i want to do the same thing in JAVA but i can't make it work. So, i would appreciate if someone could give me a simple example how to do it. Thank you.

How to create PDF from text file with specific layout?

I wanted to create the pdf from text file in specific layout - Landscape orientation and JIS B3 Page size while at Adobe Acrobat Pro.
In past, I could do a right click on a text file (desktop area) and select print to print out the document into .pdf BUT only if I set the Adobe PDF to Landscape and JIS B3 Page size BEFORE. And I could only do 15 text documents at once.
I wanted to see if I could do the create the pdf from text file with specific layout in Adobe Acrobat without having to go to Control Panel to preset the Adobe PDF to specific layout at every time. I would have to set Adobe PDF back to normal layout after I'm done with these pdf print outs. I do lots of pdfs in normal layout. Sometimes I would forget to do that.
So, How do I do that?

No such luck. It would output the contents in letter size even in JIS B3 Page layout at MS word.
Is there a script or action where I could set the orientation and page size before creating PDF on these text files?

How to get InputStream in jar file

Could anyone give me a tip how I can play this sound file inside the application jar file?
I have this package: *{color:#0000ff}com.sikgraf.ui{color}*
with *{color:#ff6600}ArquivoMagneticoUI.class{color}* and {color:#ff6600}*applause.au*{color}
I am tyring to get the InputStream but It's being painful and so far no success
Here are the 3 ways I tried:
InputStream is = ArquivoMagneticoUI.class.getResourceAsStream("applause.au");
is = getClass().getResourceAsStream("applause.au");
is = this.getClass().getClassLoader().getResourceAsStream("applause.au");All them return:
java.lang.NullPointerException
        at java.io.FilterInputStream.mark(FilterInputStream.java:175)
        at com.sun.media.sound.WaveFileReader.getFMT(WaveFileReader.java:241)
        at com.sun.media.sound.WaveFileReader.getAudioInputStream(WaveFileReader.java:160)
        at javax.sound.sampled.AudioSystem.getAudioInputStream(AudioSystem.java:1094)What I am doing wrong?

Thanks for your reply, I just figured out using URL:
    public static void playSound(int index) {
        String files[] = {"applause.au", "cash_register.au", "ding.au", "donkey_1.au", "duck_1.au", "siren_2.au"};
        String sound = "som/" + files[index];
        try {
            URL url = ArquivoMagneticoUI.class.getResource(sound);
            AudioInputStream ain = AudioSystem.getAudioInputStream(url);
            AudioFormat format = ain.getFormat();
            if (format.getEncoding() != AudioFormat.Encoding.PCM_SIGNED) {
                format = new AudioFormat(
                        AudioFormat.Encoding.PCM_SIGNED,
                        format.getSampleRate(),
                        format.getSampleSizeInBits() * 2,
                        format.getChannels(),
                        format.getFrameSize() * 2,
                        format.getFrameRate(),
                        true);        // big endian
                ain = AudioSystem.getAudioInputStream(format, ain);
            DataLine.Info info = new DataLine.Info(Clip.class, ain.getFormat(), ((int) ain.getFrameLength() * format.getFrameSize()));
            Clip clip;
            clip = (Clip) AudioSystem.getLine(info);
            clip.open(ain);
            clip.start();
        } catch (LineUnavailableException ex) {
            //Logger.getLogger(ArquivoMagneticoUI.class.getName()).log(Level.SEVERE, null, ex);
        } catch (UnsupportedAudioFileException ex) {

How to get resources from jar-files

Hi
in my app I load an image via the Toolkit.getImage() method.
Works fine if the app and the image are in folders on disk.
It fails to load the image, if the app (and the image) is packed in a jar file.
How can I get the image from there?
I try to get the image as follows:
String s = getClass().getResource("MyApp.class").getFile();
AppPath = s.substring(0,s.lastIndexOf("/"));
String PathToImages = "/images";
MyImage = (Image)Toolkit.getDefaultToolkit().getImage(AppPath+PathToImages+"/logo32.gif");The App starts and works, it just fails to load the images.
Any solutions??
thanx in advance
Herby

This is actually pretty easy. First a little background.
A Jar file is just a Zip file, with a few constructs for Java.
The getResource() method is used to create a mapping to data within the Jar file, but is actually not necessary after you know how the mapping works.
Just to give you an example of getResource:
// returned is a url to the resource you want from your Jar file.
URL myURL = MyClass.class.getResource("images/myimgage.gif");
// then you can use this URL to load the resource
Image img = getImage(myURL);If you were you look at the value of myURL you would see something similar to the followiing.
jar:http://www.mywebsite.com/mydir/myjarfile.jar!/images/myimage.gifJust to break it down for you.
The line always starts with the word jar:
Followed by the path to your jar file.
A sepearator !/
Then the file you are loading from the Jar file.
jar: path_to_jar_file !/ path_to_resource_in_jar_fileSo if you'd like, you could just create a URL object, and define the path to the object using the above method rather than using getResource.
Anyway, back to your code. What I would do is print out what you get for:AppPath+PathToImages+"/logo32.gif"I'm thinking you might be getting 2 "/" in your path because I think:AppPath = s.substring(0,s.lastIndexOf("/"));will leave the "/" at the end and the next line you add the "/" in front of the image directory name. So you my have the following for your image path.mypath//images

How to import data from CSV file with columns separated by semicolon?

I migrate database from MS SQL 2008 to ORACLE 11g
I export data to CSV file from MS SQL
then I try to import it to Oracle
several tables goes fine using Import data option in the SQL Developer
Standard CSV files with data separated by comma were imported.
chars, date (with format string), and integer data are imported via import wizard without problems
the problems were when I try to import table with noninteger numbers with modal part separated by comma not by dot
comma is the standard separator for columns in CSV file
so I must change the standard separator to semicolon
then the import wizard have problem to correct recognize the columns data because it use only standard CSV comma separator :-/
In SQL Developer 1.5.3 Tools -> Preferences -> Migration -> Data Move Options
I change "End of Column Delimiter" to ; but it doens't work
Is this possible to change the standard column separator for import data wizzard in SQL Developer 1.5.3?
Or maybe someone know how to import data in SQL Developer 1.5.3 from CSV when CSV colunn separator is set to semicolon?

A new preference has been added to customize the import delimiter in main code line. This should be available as part of future release.

How to get InputStream from String ?

Hi !
I want to get InputStream object from String.
String str = "balabalabala";
InputStream stream = getInputStream(str);
How to realize getInputStream(str) function ?
Thanks!

The preferred method nowadays is to use Readers and Writers for String data - hence StringReader(String). If you're going to operate on the InputStream directly, then I'd modify your code to use the Reader calls and go that route.
If, however, you need to pass the InputStream to some other piece of API that requires an InputStream instead of a Reader, then the ByteArrayInputStream is probably your best bet. StringBufferInputStream is deprecated because it doesn't work reliably in the face of many character encodings.
Speaking of encodings - never call Strng.getBytes() - always use the getBytes(character-encoding) version, so you KNOW what encoding you're getting!

How to get data from XML file having korea Text

I have a one XML File with Korean Text, How to read this File.
i tried with this code
BufferedReader in = new BufferedReader(
new InputStreamReader(new FileInputStream("C:/test1.xml"), "EUC-KR"));
String str = in.readLine();
but it is giving exceptions.
please suggest me, how to retrive EUC-KR text from the XML file

Standard Java does not support this Charset. You have to find a charset provider that implements "EUC-KR". But you should also consider using Unicode, which is implemented in standard Java.
