Open files with java

Hi I'd like to know if there's a way that you can open a file that's been associated with your java app. I know how to read from a file and I know how to pass command line arguments but what I don't know is how to open my app with a file just by clicking it in my file browser. If needed i could settle for a Mac-specific and a Windows-specific method.

This is nothing to do with Java, and specific to the OS you're installing to. This question comes up quite regularly, from people who are under the impression it's the responsibility of their app to enforce the file association. It isn't. Your installation should ask users if they want the association made. Remember how annoying it is when something you've just installed takes over the file associations of another app, without asking? Don't do it, your users won't like it

Did you specify <all-permissions/> in your JNLP file? Did you sign your code? What error are you getting?

Opening files with servlet

Okay... I'm new to using servlets. Not so much to jsp, just to using servlets. I have one process on our site that is using servlets and I'm trying to mimic how that is using em but am having no luck.
I am trying to open files with a servlet. I have the class built and compiled, but mainly pulled it from Java World. I evenually will need to pass the servlet the filename and path I want open but in this example it has the file set. My problem is I want to send users to a jsp file where I check user authentication and call the servlet to open the doc, but I don't know how to call the servelet or what to send it. If someone could maybe walk me through this.
Here's my servlet:
package cmxx.fileServe;
import java.io.*;
import java.util.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class fileServe extends HttpServlet {
final static String CONTENT_TYPE_DOC = "application/msword";
final static String CONTENT_TYPE_HTML = "text/html";
final static String document = "/docs/form_41.doc";
public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException
doGet(request, response);
public void doGet (HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException
PrintWriter out;
out = response.getWriter();
HttpSession websession = request.getSession(true);
response.reset();
response.setDateHeader ("Expires", 0);
response.setDateHeader("max-age", 0);
try {
     response.setContentType(CONTENT_TYPE_DOC);
FileInputStream fileInputStream = new FileInputStream(document);
ServletOutputStream servletOutputStream = response.getOutputStream();
int bytesRead = 0;
byte byteArray[] = new byte[4096];
while((bytesRead = fileInputStream.read(byteArray)) != -1) {
     servletOutputStream.write(byteArray, 0, bytesRead);
servletOutputStream.flush();
servletOutputStream.close();
fileInputStream.close();
} catch(Exception ex) {
     throw new ServletException(ex.getMessage());
} /* end doget */
} /* end class */

I'm trying a new servlet. But am getting a few compile errors. Can someone help?

Thanks in advance.

Snow Leopard 10.6.2 CS4 InDesign can't open files with a "#" in file path

Snow Leopard 10.6.2 CS4 InDesign can't open files with a "#" in file path using any of these perfectly normal methods:
1. double-click file in the Finder (e.g in a Folder on your Mac or on your Mac desktop etc.)
2. select file and choose "File... Open" command-o in the Finder
3. drag file to the application icon in the Finder.
4. Select file in Bridge and double-click, choose File.. Open.. or Drag icon to InDesign icon in dock.
If you try to open an ID file named with a "#", you will get an error message "Missing required parameter 'from' for event 'open.'"
This happens to any InDesign file that has a "#" (pound sign, number sign, or hash) in the filename or in the file path (any parent folder).
To reproduce
Name an InDesign file Test#.idd Try to open it in the Finder or Bridge (as opposed to the "Open" dilaog of InDeisng itself).
"Solution"
The file WILL open using File... Open... command-o while in InDesign application.
Rename the file or folders that have a "#" (shift-3) in the filename.
Report to Adobe if it bugs you.
This does not occur in "plain" Leopard 10.5 nor Tiger 10.4
Untested in Panther or before and
Untested with CS3 and earlier in Snow Leaopard.
Anyone have those and want to try this... ?

In case this really bothers you: we've added a workaround for this into Soxy. If you enable the option, these documents will open fine on double-click.
You need Soxy 1.0.7 from:
http://www.rorohiko.com/soxy
Go to the 'Soxy' - 'Preferences' - 'Other' dialog window, and enable 'Open InDesign via Script'
(Irrelevant background info (it's all invisible to the user): the workaround works by special-casing how Soxy opens documents in InDesign: instead of using AppleScript, Soxy will use ExtendScript to instruct InDesign to open the document - which works fine).

This problem appears after opening 4 a 5 files, rebooting helps another 4 a 5 times and appears again.

I'd recommend reposting in the Boot Camp forum, that is where the Boot Camp and Windows gurus hang out.
Good luck.

Can´t open files with camera raw

Hi!
I use Adobe Photoshop CS3 and the option to open files with Camera Raw is disabled in Bridge and in PS.
Can anyone help?

While each situation can be different this has been discussed on several threads. Scan down the list or do a search. If you can't find the answer, post a note.

If you are unable to enter the passcode into your device, you will have to restore the device to circumvent that passcode.
Is the music purchased from iTunes? If it is you can contact iTunes support and ask them to allow you to re-download the music that you purchased from iTunes.
Also, do you sync the device regularly? When syncing an iPod Touch/iPhone a backup file is made. That backup file doesn't contain your music but it does contain your address book, application data, pictures, notes, etc. After restoring your device, you can try restoring from the last backup that was made of your device so you will not have to start over completely from scratch.
Hope this helps!

How to use parameter file with java

Is it possible to use a parameter file with Java, and is there any class/method to make it easy to call and use these parameter from a text file, other than scanning the whole text file manually as we can do normally with visual basic/c++, so we can call the program with the parameter file, like java testing c:\\testing.ini

If I understand you correctly, you may be looking for a properties file. This is basically a text file that contains pairs of strings in the form:
parameter1=value1
parameter2=value2
parameter3=value3
...etc.
and the values are retrieved using the java.util.Properties class - see:
http://java.sun.com/j2se/1.3/docs/api/java/util/Properties.html
Sample use://Call chis method once, to load the props file.
//props file is called "demo.properties", and is
//in a directory that is included in the classpath
    private void loadMyProperties() throws Exception
     InputStream stream = getResourceAsStream("/demo.properties");
     if(stream == null)
         throw new Exception("stream is null!");
     demoProperties = new Properties();
     demoProperties.load(stream);
     stream.close();
// Then you can retrieve properties in your code using:
String param3 = demoProperties.getProperty("parameter3");
//...etc

Developer: How can I let people open files with my program?

Hello Everyone,
I just finished my program for the Mac, and decided to make it an application.
I used Platypus to make my program into an application. Unfortunately when I try to open a file with my program (control + click on file + open with -> other), my application is grayed out and I can't select it. I see it there along with the other applications but I can't select it like I can Mail or TextEdit.
I read somewhere I had to use XCode to let people open files with my program but I have never used XCode and I have no idea how to do that. Any help would be appreciated.
Thanks,
Nick

You've posted in the wrong forum. This is the OS X Leopard Installation and Setup forum. You need to post your problem in the Developers forum. Also, since Platypus is not an Apple product, you should visit it's developers forum for assistance. The Apple Discussions is intended to assist users with problems and questions about Apple products only.
To use XCode Tools you need to install it from the Optional Installs folder on your OS X Installer Disc One. It comes with documentation. More assistance can be found at developer.apple.com.

Can't create log file with java.util.logging

Hi,
I have created a class to create a log file with java.util.logging
This class works correctly as standalone (without jdev/weblogic)
import java.io.IOException;
import java.text.DateFormat;
import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.logging.*;
public class LogDemo
     private static final Logger logger = Logger.getLogger( "Logging" );
     public static void main( String[] args ) throws IOException
         Date date = new Date();
         DateFormat dateFormat = new SimpleDateFormat("yyyyMMdd");
         String dateStr = dateFormat.format(date);
         String logFileName = dateStr + "SEC" + ".log";
         Handler fh;
         try
           fh = new FileHandler(logFileName);
           //fh.setFormatter(new XMLFormatter());
           fh.setFormatter(new SimpleFormatter());
           logger.addHandler(fh);
           logger.setLevel(Level.ALL);
           logger.log(Level.INFO, "Initialization log");
           // force a bug
           ((Object)null).toString();
         catch (IOException e)
              logger.log( Level.WARNING, e.getMessage(), e );
         catch (Exception e)
              logger.log( Level.WARNING, "Exception", e);
}But when I use this class...
import java.io.File;
import java.io.IOException;
import java.text.DateFormat;
import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.logging.FileHandler;
import java.util.logging.Handler;
import java.util.logging.Level;
import java.util.logging.Logger;
import java.util.logging.XMLFormatter;
public class TraceUtils
public static Logger logger = Logger.getLogger("log");
public static void initLogger(String ApplicationName) {
    Date date = new Date();
    DateFormat dateFormat = new SimpleDateFormat("yyyyMMdd");
    String dateStr = dateFormat.format(date);
    String logFileName = dateStr + ApplicationName + ".log";
    Handler fh;
    try
      fh = new FileHandler(logFileName);
      fh.setFormatter(new XMLFormatter());
      logger.addHandler(fh);
      logger.setLevel(Level.ALL);
      logger.log(Level.INFO, "Initialization log");
    catch (IOException e)
      System.out.println(e.getMessage());
}and I call it in a backingBean, I have the message in console but the log file is not created.
TraceUtils.initLogger("SEC");why?
Thanks for your help.

I have uncommented this line in logging.properties and it works.
# To also add the FileHandler, use the following line instead.
handlers= java.util.logging.FileHandler, java.util.logging.ConsoleHandlerBut I have another problem:
jdev ignore the parameters of the FileHandler method .
And it creates a general log file with anothers log files created each time I call the method logp.
So I play with these parameters
fh = new FileHandler(logFileName,true);
fh = new FileHandler(logFileName,0,1,true);
fh = new FileHandler(logFileName,10000000,1,true);without succes.
I want only one log file, how to do that?

[Flex mobile] Open file with a Filebrowser

Hi everyone,
i want to be able to open files with a file browser in my app, but the browse dialog which is opened by the File.browse() method only displays / opens music or image files. Furthermore im not even able to change the Dialog header when running my project on android:
dir.browseForOpen("Please select a file");
this doesn't work on android, neither does the next code-block:...
var dir:File=new File(File.userDirectory.url+ "/geoforms");
var filter:FileFilter=new FileFilter("Documents","*.txt");
dir.browseForOpen("Please select a file",[filter]);
So what do i have to do, to be able to show a decent file select dialog ?

Nobody any idea?
i tried it like its described in this article:
Declaring file type associations
http://livedocs.adobe.com/flex/3/html/help.html?content=File_formats_1.html
but i can't get it running for my mobile project. The type associations works fine in my desktop air application but it doesn't work in my mobile app. Is this type associations stuff supposed to be working on mobile devices / android?
