Summary: Desktop API is not supported on the current platform Classification: openSUSE Product: openSUSE 11.4 Version: Final Platform: i686 OS/Version: openSUSE 11.4 Status: NEW Severity: Normal Priority: P5 - None Component: Java AssignedTo: bnc-team-java@forge.provo.novell.com ReportedBy: johannes.mueller@troeber.com QAContact: qa@suse.de Found By: --- Blocker: ---
User-Agent: Mozilla/5.0 (X11; Linux i686; rv:2.0.0) Gecko/20100101 Firefox/4.0
We are trying to run a java applet in Firefox (4.0) or Konqueror, which should open a new window with desired information. The new window doesn't open and we get this error on the java console:
--------- UNCAUGHT EXCEPTION --------- 21.2.2011 13:49:18 java.lang.UnsupportedOperationException: Desktop API is not supported on the current platform at java.awt.Desktop.getDesktop(Desktop.java:126) at start.start.showTrackingPage(start.java:2895) at start.start.setSearchResults(start.java:3145) at tools.AS400_Connection.transmittData(AS400_Connection.java:283) at tools.AS400_Connection.run(AS400_Connection.java:241) at java.lang.Thread.run(Thread.java:662) --------------------------------------
Reproducible: Always
Steps to Reproduce: 1. Load java applet 2. Click on a detail position to run the tracking information
Expected Results: Should open a new window with redirect to the tracking provider. Works so far on OpenSuSE 11.2 and OpenSuSE 11.3. Also works on any Windows Systems (XP or 7). I guess its related to KDE 4.6.

--- Comment #2 from Johannes Müller johannes.mueller@troeber.com 2011-03-31 11:38:06 UTC --- Hi Michael,
we are using SUN Java 1.6.24, due to the applet doesn't work with openjdk.

--- Comment #3 from Michal Vyskocil mvyskocil@novell.com 2011-03-31 12:12:34 UTC --- As far I understood the underlying code (quite complicated due a lot of abstract classes and native glue) I suppose the desktop support in Java is done directly by dlopen of libgnome-2.so.0 and libgnomevfs-2.so. When dlopen calls fails, the safe HeadlessToolkit is instantiated. And is always returns false on isDesktopSupported (which btw have to be called before getDesktop ;-).
Can you post me the output of this program?
public class d {
public static void main(String[] args) {
System.out.println("awt.toolkit: " + System.getProperty("awt.toolkit")); //, "sun.awt.X11.XToolkit");
java.awt.Toolkit defaultToolkit = java.awt.Toolkit.getDefaultToolkit(); System.out.println(defaultToolkit);
if (defaultToolkit instanceof sun.awt.SunToolkit) { //return ((sun.awt.SunToolkit)defaultToolkit).isDesktopSupported(); System.out.println("Toolkit is instance of sun.awt.SunToolkit"); }
if (defaultToolkit instanceof sun.awt.HeadlessToolkit) { System.out.println("Toolkit is instance of sun.awt.HeadlessToolkit"); }
if (java.awt.Desktop.isDesktopSupported()) { System.out.println("Desktop is supported"); } }
}
and of course the output of
strace -f -eopen java d 2>&1 | grep libgnome
if I see if my assumptions are correct.

--- Comment #4 from Johannes Müller johannes.mueller@troeber.com 2011-03-31 12:25:48 UTC --- How do I compile/run that piece of code on openSuSE? I know that I can do it with javac on Windows.

--- Comment #5 from Johannes Müller johannes.mueller@troeber.com 2011-03-31 12:38:41 UTC --- Okay, just download the JDK and compiled your baby. Running the programm gave me:
java d
awt.toolkit: null sun.awt.X11.XToolkit@1551f60 Toolkit is instance of sun.awt.SunToolkit
output of "strace -f -eopen java d 2>&1 | grep libgnome":

--- Comment #6 from Johannes Müller johannes.mueller@troeber.com 2011-03-31 12:42:55 UTC --- And my problem is gone. I just installed: libgnome-2.32.0-4.1 And it works. Shouldn't that package be predepend, on the OpenSuSE 11.4 distro?
Thank you very much Michael!

--- Comment #7 from Michal Vyskocil mvyskocil@novell.com 2011-03-31 14:09:28 UTC --- It seems that Fedora KDE people already found this issue

I think before we will add Supplements into libgnome2 package (I'm sure it will disappear soon from major distributions), we should change the behavior - at least for openjdk, but Oracle devs might be involved as well.

--- Comment #8 from Michal Vyskocil mvyskocil@novell.com 2011-04-01 09:27:53 UTC --- I moved the discussion to icedtea mailinglist, so closing here as RESOLVED/UPSTREAM.
http://mail.openjdk.java.net/pipermail/distro-pkg-dev/2011-April/013376.html
BTW: case of Oracle JVM is not clear, maybe the solution from icedtea will be accepted, maybe not.
