How to gzip a file using java

Friends,
I want to gzip a file in unix using my java program, can I use Runtime.exec() method and run the gzip command to achieve this ?
Is there any other way to zip/compress a file using java api ?
Thanks

How to print PDF files using java print API

Hi,
I was goign throw lot of discusion and reading lot of forums related to print pdf files using java api. but nothing seems to be working for me. Can any one tell me how to print pdf files using java api.
Thanks in advance

Mike,
Can't seem to get hold of the example described in your reply below. If you could let us have the URL to get then it would be great.
My GUI application creates a pdf document which I need to print. I want to achieve this using the standard Java class PrinterJob (no 3rd party APIs I'm afraid, commercial restraints etc ..). I had a stab at it using the following code. When executed I get the pretty printer dialog then when I click ok to print, nothing happens!
boolean showPrintDialog=true;
PrinterJob printJob = PrinterJob.getPrinterJob ();
printJob.setJobName ("Contract.pdf");
try {
if (showPrintDialog) {
if (printJob.printDialog()) {
printJob.print();
else
printJob.print ();
} catch (Exception PrintException) {
PrintException.printStackTrace();
Thank you and a happy new year.
Cheers,
Chris

How to hide hidden files using java FileSystemView

My application has a browser. I use the following method from FileSystemView
public File[] getFiles(File dir,
boolean useFileHiding)
with false as the second argument so that the browser doesn't display hidden files.
It doesn't work completely.
I found out there are two types of hidden files in Mac. the ones that being with "." (unix based) and the ones that have an invisibility attribute for the meta of the file (folders like /usr, /bin, /tmp, /etc).
The getFiles filter works only for hidden files that start with "." but it still shows the second type of hidden files.
For the second type of hidden files in Mac, how can I get the invisibility file attribute information in Java so that I can hide them from the file browser?
thanks,

The GetFileInfo tool that ships with the XCode Tools can display the file's information. Additionally, the SetFile tool allows setting those flags. How you use java to implement those, I suggest you ask at the Unix forum under OS X Technologies.

How to play movie file using java tv

hi,
i am trying to play movie file(.mov or mpg or mp3) using java tv in linux plotform and also using jmf jar.
problem is while running appear black screen and getting exception or errors like
Unable to handle format: ima4, 480x320, FrameRate=25.0, Length=460800 0 extra bytes
Thank in adv

Well...
I don't know how to load and play a video with JavaTV. But I've seen some posts telling that .mpg files aren't accepted by the JavaTV.
Some people said that I had to use .avi files and these .avi files, if they were converted from a .mpg file, must had been converted with the Cinepack technology, but I don't know how to do this.
If you find out how to load and play a video, I'd like to know, please send me an email or access my page and post there in the comments, so I can continue doing my application with a video.

How to read SGML files using Java

I've got a text categorisation test collection called Reuters-21578 for my Information Retrieval project. It is distributed in 22 files. Each of the first 21 files (reut2-000.sgm through reut2-020.sgm) contains 1000 documents, while the last (reut2-021.sgm) contains 578 documents. The files are in SGML format. Each of the 22 files begins with a document type declaration line:
<!DOCTYPE lewis SYSTEM "lewis.dtd"> The DTD file lewis.dtd is included in the distribution. Following the document type declaration line are individual Reuters articles marked up with SGML tags.
My questions is how to write a java program to read those 21578 documents or transform them into 21578 seperated text files.

I guess I missed something. What is Renes link?. The
parser stuff isn't really what I'm looking for. I'm
a new at and just learning java and I just want to
know the easiest way to read a SGML file. Should I
use a buffered Reader with a Pushback Input Stream?Hang on.....you want to just read the file without intelligently extracting the SGML data contained within and so have no need of a parser?
Well, in that case, its just text.....so just use BufferedReader or whatever to read the text data. If I understand you correctly, all you really wanted to ask was "how do I read a text file?"

How can I trasfer file using java program (from NT to Unix)

Hi all,
I want to transfer a text file from Windows NT to Unix machine inside the Java program.
How should i do it.
Thanks in advance.
Regards
Rajeev

you have several options:
- make your system administrator software install software on Unix and NT so that you can see a directory on the Unix machine from your NT machine, and just copy the file there
- use FTP to put the file on the Unix machine
