Desktop class

Hey
I am trying to print a document using the new java class Desktop class.
Desktop desktop = null;
if (Desktop.isDesktopSupported())
desktop= Desktop.getDesktop();
try {
desktop.print(new File(aFileFullPath));
catch (IOException e)
// TODO Auto-generated catch block
e.printStackTrace();
if(desktop.isSupported(Desktop.Action.PRINT))
System.out.println("print supported");
I get no exception running the code and also the "print supported" message is been displayed, but nothing happens, the file is not printed! I was trying also the command for open a file and the same result, no exceptions and no operation are been taken.
I was trying to run the Desktop example: http://download.oracle.com/javase/tutorial/uiswing/misc/desktop.html
But same result, the project is running but no operations are taken.
The only thing I found regarding this issue is Changing File Associations, but for example If I am trying to print or open a .DOC file under windows the system already associate the file with Microsoft Word application...
Thanks,Natalie

Smells like a bug to me. Check the bug database for similar bugs and if you do not find one, raise a new report. Use the DesktopDemo.java as the source for the report. There is nothing quite more definitive than Oracle's own demo. code!
BTW - I am guessing you edited your post? If so, you went about it the wrong way. If the 'back button' is used to edit a post, it results in 2 posts. Instead use the 'edit' link on the top right of the last message. Note that I would have replied sooner, but first I wanted to ensure the other post was deleted so people do not waste time replying to 2 threads. 0_o
Added to that, the reply was further delayed by me having to type that. ;)

Installer hanging on selecting Desktop Class

Morning,
I downloaded the 32 bit Windows 11.2.0.3 patchset from My Oracle Support early on in the week. When I try to install it on a Windows 7 machine, the installer hangs on the 'Installing Database' page after I select 'Desktop Class' and press the Next button.
I had earlier chosen to skip software updates and the create and install a starter database option.
Has anyone else experienced this, are there any log files created by the installer at this point that I can look at or can anyone help with a solution?

Thanks Srini,
I can confirm I have met all the pre-requirements and don't have spaces in the folders.
The machine being installed on is Windows 7 SP1

Desktop class problem

The code below does nothing. No file opened, no exception thrown, no output.
What can I do to discover the problem?
It does indeed execute the desktop.open(file) line.
Using JDK 1.16.0_81
File file = new File(pathAndFileString); // an existing text file
if (Desktop.isDesktopSupported()) {
     Desktop desktop = Desktop.getDesktop();
     if (desktop.isSupported(Desktop.Action.OPEN )) {
          try {
               desktop.open(file);
          } catch (IOException e1) {
               e1.printStackTrace();
     else {
          System.out.println("Desktop.Action.OPEN not supported");
else {
     System.out.println("Desktop not supported");
}

package desktopdemo;
import java.awt.Desktop;
import java.io.File;
import java.io.IOException;
public class MyDesktopDemo {
     public MyDesktopDemo() {
          // have tried .txt, .rtf, .pptx all with no effect
          String pathAndFileString = "C:\\my.pptx";
          File file = new File(pathAndFileString);
          if (Desktop.isDesktopSupported()) {
               Desktop desktop = Desktop.getDesktop();
               if (desktop.isSupported(Desktop.Action.OPEN )) {
                    try {
                         System.out.println("desktop.open(" + pathAndFileString + ")"); // gets here
                         desktop.open(file); // but nothing happens
                    } catch (IOException e1) {
                         e1.printStackTrace();
               else {
                    System.out.println("Desktop.Action.OPEN not supported");

Can't print using Desktop class

I found some code to print out a text file at this site:
http://www.java2s.com/Code/Java/CatalogJava.htm
import java.awt.Desktop;
import java.io.File;
import java.io.IOException;
public class print
public static void main(String[] a)
    try
      Desktop desktop = null;
      if (Desktop.isDesktopSupported())
        desktop = Desktop.getDesktop();
      File f = new File("C:\\a.txt");
      desktop.print(f);
    catch (IOException ioe)
      ioe.printStackTrace();
}but I get this run time message:
C:\java>javac print.java
C:\java>java print
java.io.IOException: Failed to print file:/C:/java/graphics.java. Error message:

What is wrong with the code?

I've got XP/SP2 here, so your mileage might vary.
When I looked I saw that .java files were configured to open with Notepad ie there was an "open" entry in the menu when you right clicked on them, and Notepad would start when you double clicked on them.
When I compiled and ran your program (changing the file name) this is what I saw:
    C:\>javac -cp . A.java
    C:\>java -cp . A\\    java.io.IOException: Failed to print file:/C:/A.java. Error message: The paramet\\    er is incorrect.

    C:\>Here's how I registered Notepad to print .java files: From Windows Explorer I choose "Tools" then "Folder Options". In the "File Type" tab I scrolled down to "JAVA" - the file types are listed alphabetically b extension - and then clicked the "Advanced" button. From there you are able to add a new action. Actions are the things that appear in the context menu when you right click an icon in Windows Explorer. In fact I added two actions: open and print.
For instance to print the application was
    C:\WINDOWS\System32\NOTEPAD.EXE /p %1
Use DDE was ticked, the application was set to NOTEPAD and the Topic was System. The open action was the same except that the application lacked the /p part. I added the open action before the print action.
(I should explain that I added both and choose the settings I did by looking at how TXT files were already set up in the "File Type" pane of the "Folder Options" dialog).
After closing and OKing everything, I ran the program again.
    C:\>java -cp . A
    C:\>This time the file printed OK.

How do I configure portal desktop to use my own custom tag in template?

I seem to have tried everything. I want to use a custom tag from a jar file on a template JSP. I keep getting error saying tag library not found. I have the tld in the meta-inf of the jar. I tried putting the jar in the desktop classes, the deployed WEB-INF lib directory for portal, in the web-src directory for the portal. I tried configuring the uri in the web.xml for the portal webapp. None of these have worked. Does someone know how to do this? If someone could help out that would be great. I tries the jar from a web application and it worked fine. I just need to get this working with Portal Server.
Thanks,
Frank

Thank you for the reply Alex. We are using the Dynamics AX 2012 R3 ISO for our installation. In the software requirement documentation for Dynamics AX it says that is able to run on Windows Server 2012 R2. I believe the prerequisites for Dynamics AX and
Dynamics CRM are different. We received a response from another forum that you can change the .NET version that Sharepoint 2010 uses through IIS in the application pool, but even after setting it to .NET v2.0, we still receive the error in the Dynamics log
that says it is not compatible with .NET v4.0. So I suppose the question is, where does the Dynamics AX 2012 R3 prerequisite checker look to see which version of .NET Sharepoint is using?
Thanks again for the reply!

Desktop.open() Problem

I recently put together an application that relied heavily on the Desktop.open( ) method and several other methods from the Desktop class. However, all of a sudden the Desktop.open() does not work. I believe I read some where that this was due to the ShellExecute function or dll or something like that.
However, since my app is targetted at the Windows platform I resorted to using windows Explorer to launch the system default applications for files using a the code below
public static void openFile(File file) {
try {
    Runtime runtime = Runtime.getRuntime();
    runtime.exec( "explorer.exe \"" + file.getAbsolutePath() + "\"" );
} catch(IOException) {
    ioe.printStackTrace();
    JOptionPane.showMessageDialog(null, "Could Not Open File Location: " + file.getAbsolutePath());
}The code works as expected, but my problem is that I am loosing cross-platform functionality.
Can any point my to solution to this Desktop.open( ) problem, or probably add the my list platform dependent launch procedures so at least the code works on Windows,Linux and Mac.
ICE

Thanks Andrew,
I've do a more simple example of the problem. I create two files on "\\fiuu\proyectosShared", one called "test.txt" and the other one called "te st.txt". I execute your exact source for the who paths whith these results:
File f = new File("//fiuu/proyectosShared/test.txt");
System.out.println(f + " exists: " + f.exists());
dt.open(f);
RESULT:
\\fiuu\proyectosShared\test.txt exists: true
(notepads opens the file)The second test does'nt work:
File f = new File("//fiuu/proyectosShared/te st.txt");
System.out.println(f + " exists: " + f.exists());
dt.open(f);
RESULT:
\\fiuu\proyectosShared\te st.txt exists: true
Exception in thread "main" java.io.IOException: Failed to open file:////fiuu/proyectosShared/te%20st.txt. Error message: El sistema no puede hallar la ruta especificada.
     at sun.awt.windows.WDesktopPeer.ShellExecute(WDesktopPeer.java:59)

     at DesktopTest.main(DesktopTest.java:14)
(translation of error message: System can't find specified path)I've also done some tests with Desktop.browse(file.toURI), and some others with no success.
Something curious: try to execute Runtime.getRuntime().exec("explorer " + f.getAbsolutePath) for a file that has thow white spaces on his name....
File f = new File("//fiuu/proyectosShared/te st.txt");//with two white spaces
System.out.println(f + " exists: " + f.exists());
Runtime.getRuntime().exec("explorer " + f.getAbsolutePath());
\\fiuu\proyectosShared\te st.txt exists: trueSystem says:

How to use java class in jsp page of JSPProvider?

Hello everybody.
I created simple JSPProvider channel with portal amconsole and named it "jspprov1". Then I created "jspprov"1 directory under "/ets/opt/SUNWps/desktop/sampleportal". I put "index.jsp" in it. And it worked until I add this line into "index.jsp": <% @page import="jspprov1package.aclass1" %>. Then I created directory "jspprov1package" under "/ets/opt/SUNWps/desktop/classes" and put "aclass1.class" into it and into "/ets/opt/SUNWps/desktop/classes" itself. I created "aclass1.class" on the other machine (with no installed portal) in j2sdk1.4.1_02: "javac aclass1.java". The text of this class is simple:
"package jspprov1package;
public class aclass1{
public int int_field = 10;
But the page still don't work. It writes on the portal desktop "ERROR: Content is not available".
Does anybody know why this happened?

Sorry, there were mistakes in jsp page and java files.
I maked the channel "show exceptions" and found them out.

Need Classes help......

Hi all,
i was wondering if anyone can help me out with my code.
i've got a class Desktop, and a class menu.
the class Desktop contains the following...
public class Desktop extends JFrame implements ActionListener{
protected JDesktopPane thedesktop;
protected JMenuBar jMenuBar1;
protected ..........and all elements declared here..
public Desktop(){
super("application");
menu mymenu = new menu(); //class will build the menubar
setJMenuBar(jMenuBar1); //adds menubar to jframe
bla bla.......
public static void main(String args[]){
Desktop app = new Desktop(); //call constructor
}the class menu is as follows
public class menu extends Desktop{
public menu() {
jmenubar1 = new JMenuBar();
//add all items to jmenubar1
//all menus etc are declared in desktop, and initalized here
// as this class extends desktop class
}in desktop, i want the class menu to build the jmenubar for me,
the i add the jmenubar with the line..setJMenuBar(jMenuBar1);
both classes compile with no errors, but will not run, stalls on the commandline.
can anyone see what i'm doing wrong ???
it's something to do with the second class extending Desktop, and calling that constructor.
is there a way around my problem ???
thank you so much
Paul

Why don't you try this another way
public class Desktop extends JFrame implements ActionListener{
         protected JDesktopPane thedesktop;
         private Menu myMenu;
      public Desktop(){
             super("application");
              myMenu = new Menu(); //class will build the menubar
              setJMenuBar(myMenu.getMenuBar() );// call to the method in class Menu that will return a menubar
public static void main(String args[]){
            Desktop app = new Desktop(); //call constructor
class Menu extends Desktop{
     JMenuBar menuBar;
public menu() {
        menuBar = new JMenuBar();
        // and all your stuff here
public JMenuBar getMenuBar(){
        return menuBar;
}

Dynamically Calling a built-in API Class

Ok...
Scenario:
I'd like to pick between an internal pdf viewer and an external using the java.awt.Desktop class.
Unfortunately, for development purposes, I need the code to compile on Java 1.5 (1.5 doesn't have java.awt.Desktop)
Eventually we'll move to 1.6, but until we do, the other contributors don't want to be bothered with commenting out the 1.6 code.
I figured I could dynamically load the class with:
Class.forName("java.awt.Desktop")or perhaps
Class.forName("java.awt.Desktop").newInstance()The Desktop class complains about modifiers "private".
I tried calling the Desktop.open method directly with:
Class.forName("java.awt.Desktop").getDeclaredMethod("open", new Class[]{java.io.File.class};).invoke(null, pdfFile);With no luck either.
I'm compiling on Java 1.6, with the hopes that the 1.5 compilers won't complain. Is this possible, or am I trying to do something outside the scope of Java?
-FBL

Hey guys, this WORKS! Infact, the compiled Java 1.5 version flawlessly opens the application with our 1.6 clients!
I'm pretty impressed that java has this flexibility! Thanks all!
Here's my exact code. I had to remove a few nulls to supress warnings.
try {
        desktopCall("open", new File("C:\samplefile.pdf"));
catch (Exception e) {
        // Open w/ internal viewer
public static void desktopCall(String call, Object o) throws Exception {
     Class[] f = new Class[]{java.io.File.class};
     Object obj = Class.forName("java.awt.Desktop").getDeclaredMethod("getDesktop").invoke(null);
     Class.forName("java.awt.Desktop").getDeclaredMethod(call,f).invoke(obj,o);

Calling Desktop.open() on avi/mp3/wmv/etc (media) files.

Hello all,
I am using the Desktop class to open files on the desktop in my signed applet. This is working perfectly for ppt, pps, doc, xls, txt, jpg, pdf files. However, for some reason I am unable to launch any media-type files using this method. I get errors such as "java.io.IOException: Failed to open file:/C:/Users/Bryan/Desktop/4542-sun/Butterfly.wmv. Error message: No application is associated with the specified file for this operation."
However, there are indeed applications associated with these file types... namely Windows Media Player. Double-Clicking the file directly launches it in WMP as it should. I have been searching around high and low, and can't find much. Note the fact that it is trying to open a URI, starting with file:/. Originally it was just opening the location directly, but I tried using a URI instead to no avail.
This has happened on 3 separate computers now.
I have done a work around using Runtime.getRuntime().exec(). However, some of the filenames I am working with can possibly have asian and other UTF-8 characters. That causes a whole new issue, described in http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4947220. I have no idea how to begin using JNI to directly call ShellExecute or if that is even possible from a signed applet standpoint.
Does anyone have any idea how to fix the issue with Desktop.open() and media files?
Thanks

Ok I have searched and searched and found no reliable solution for either of the previous issues. Since this applet is run on a closed intranet, with no fear of malicious intent, I have gone for a different route.
try {
     desktop.open(new File(fileToOpen.toURI()));
} catch (Exception e) {
     window.call("launchFile", new Object[] { file.toString() });
}When the call to Desktop.open() fails, I catch the exception and call a javascript function launchFile(), defined below.
function launchFile(filename) {
        var o = new ActiveXObject("WScript.Shell");
        o.run(filename);
}Of course, this limits us to IE ... but it is a necessary evil until Sun fixes the bugs in Desktop.open() and Runtime.exec().
Hope this helps someone. Again, I still welcome other options.

Desktop.open() method doesn't work,

Hi,
I'm developing file explorer with JDK6.
But when I try to open file with native asscociation programs with java.awt.Desktop class, I found that's not work at all.
there is no response, exception and error. it just 'silent.'
I checked each line of code. File is exist, Desktop support Open action.
OS association with file is correct. I couldn't find any problem.
so I tested tutorial code 'DesktopDemo'. it worked well Browse() but not Open(). open() method isn't work. (It also silent)
How can I open file with native association?

Unfortunately the moderators of this forum have the tendency to close/lock old topics so we cannot add new information to a long running problem anymore after a while. They forgot to close this one so luckily I can still add some info here.
I would like to invite anyone wanting to read details on and discuss this issue to do so on my blog. The comments on that post will never be closed or locked.

Desktop.browse() won't show URI fragments on Windows

Hi. I'd like to use the Desktop API in my application when the user clicks on various 'help' buttons. My reference manual for the application is one large HTML file, and so if the user clicks on a 'help' button when he's in the 'configuration' menu, for example, I want to be able to do something like this:
desktop.browse (java.net.URI.create ("file:/c:/html/help.html#configuration"))... so his browser will go straight to the 'configuration' part of the HTML file, as per the "#configuration" fragment part of the URI.
Unfortunately I can't get Internet Explorer to work with URL fragments. If I use the above bit of code Explorer will start properly and display the html file ... but remain at the very top of the file.
Yet the code works fine under Linux (KDE runs up Konqueror and goes straight to the tagged 'configuration' section).
There are no errors, no exceptions thrown, and Internet Explorer does properly run and display the HTML file ... it simply stays at the very top of the file.
I also note that, in the address box (I'm probably using the wrong name for it - the text area where one can manually type in a URL in a browser) only the part of the URL without the fragment is listed ... even though the program calls desktop.browse() with the full URI including the "#configuration" fragment tail. It's as if something is stopping Explorer from 'noticing' or registering the fragment part of the URI.
Can anyone help?

I tried using URLs with the "Run" prompt in Windows XP SP2 with Firefox and Internet Explorer 7 and they work just fine if launched in the format:
iexplore http://code.google.com/apis/analytics/docs/gdata/gdataAppEngine.html#retrievingData
"C:\Program Files\Firefox\firefox.exe" http://code.google.com/apis/analytics/docs/gdata/gdataAppEngine.html#retrievingDataI haven't tried it with the Desktop class.
Note, I also tried using a "%23" in place of the "#" as a potential work-around, but it doesn't seem to work.
Edit:
I was able to reproduce the issue using the following sample html file:
<html>
Testing...
 
<h1><a name="1"/>Bookmark #1</h1>
 
<h1><a name="2"/>Bookmark #2</h1>
 
<h1><a name="3"/>Bookmark #3</h1>
 
<h1><a name="4"/>Bookmark #4</h1>
</html>In my tests, Internet Explorer DOES NOT automatically scroll to the page marker.
iexplore file:///C:/Documents%20and%20Settings/Administrator/Desktop/test.html#1Firefox DOES automatically scroll to the page marker.
"c:\Program Files\Firefox\firefox.exe" file:///C:/Documents%20and%20Settings/Administrator/Desktop/test.html#1Have you tried using a default browser other than Internet Explorer? In both cases, the "#" does not get stripped off.

11gR2 Installer - Desktop vs Server option

Hi all,
I am installing 11gR2 on SLES 11, and in the installer gui screen, there is Desktop and Server Install type option.
Can I install server type on desktop pc and vice versa desktop on server machine?
I am given a HP machine, and i dont know if it is a server or workstation desktop because it looks like server too.
How can i tell if a machine is a server or a workstation?
Thanks a lot,
Yxz

"If you are installing on a laptop or a desktop, then select the Desktop Class option; otherwise, select the Server Class option to install on a server. These options are available on the System Class screen.
There is no difference in the software that gets installed after you select any one option but the Desktop Class option installs a single instance database without the advanced configuration options."

Desktop API

Hi guys,
How can I check whether any given file type is supported, before actually opening it.
The open method opens the file straight away, and in case the file hasn't any associated application it raises an exception, but there is no what that I am aware of that lets me query the os to know if it "undestands" the file.
Thanks,
MeTitus

I looked at the source for the Desktop class before:
 private static void checkFileValidation(File file){
 if (file == null) throw new NullPointerException("File must not be null");
 if (!file.exists()) {
 throw new IllegalArgumentException("The file: "
 + file.getPath() + " doesn't exist.");
 file.canRead();
 private void checkActionSupport(Action actionType){
 if (!isSupported(actionType)) {
 throw new UnsupportedOperationException("The " + actionType.name()
 + " action is not supported on the current platform!");
 private void checkAWTPermission(){
 SecurityManager sm = System.getSecurityManager();
 if (sm != null) {
 sm.checkPermission(new AWTPermission(
 "showWindowWithoutWarningBanner"));
 public void open(File file) throws IOException {
 checkAWTPermission();
 checkExec();
 checkActionSupport(Action.OPEN);
 checkFileValidation(file);
 peer.open(file);
 private void checkExec() throws SecurityException {
 SecurityManager sm = System.getSecurityManager();
 if (sm != null) {
 sm.checkPermission(new FilePermission("<<ALL FILES>>",
 SecurityConstants.FILE_EXECUTE_ACTION));
 }But the method that actually opens the file is provided by the DesktopPeer.open() method which is implemented natively, so I really think that there is not way to get this done the way it was supposed to be, lets just hope they add some more usufull methods to the Desktop class.
