Testing Java Web Start - javaws, Fedora 17

Case 1: Google Chrome Browser or Firefox Browser without the icedtea-web plugin installed. In this case the .jnlp file is downloaded but not automatically run by the browser. For some reason Firefox is icedtea-web plugin friendly but Google Chrome is not. I don't know why that is. Go to http://docs.oracle.com/javase/tutorial/deployment/webstart/deploying.html.Click the "Launch Button" that is near the top of the page.This will cause the file "dynamictree-webstart.jnlp" to be downloaded to your machine.Type "javaws dynamictree-webstart".You should see this



Case 2: Firefox Browser with the icedtea-web plugin installed.  > rpm -qa | grep icedtea icedtea-web-1.3-1.fc17.x86_64

Open Firefox and go to the same link as above: http://docs.oracle.com/javase/tutorial/deployment/webstart/deploying.html.Click the "Launch Button" that is near the top of the page as before.This will again cause the file "dynamictree-webstart.jnlp" to be downloa…

alternatives --install gets stuck: failed to read link: No such file or directory

Alternatives utility gets stuck doing install. Fedora 17 x86_64.

Removing the /var/lib/alternatives/javaws file resolved the issue (for me).

# alternatives --install /usr/bin/javaws javaws /usr/java/jdk1.7.0_07/jre/bin/javaws  20000
failed to read link /usr/bin/javaws: No such file or directory

When updating Java this 

kbuildsyscoa4 KConfigIni Invalid Escape Sequence

Fedora 17 x86_64

After a recent update got a bunch of these in a terminal session.


kbuildsycoca4 running...
"KConfigIni: In file /home/me/.local/share/applications/wine/Programs/Spotify.desktop, line 4: " "Invalid escape sequence "\ "." 

Most of these warnings referred to .desktop files whose "Categories" line did not terminate with a ";".

OK fine. Those were easily fixed.

But the above message related to this line in my Spotify.desktop file,

Exec=env WINEPREFIX="/home/me/.wine" wine C:\\\\windows\\\\command\\\\start.exe /Unix /home/me/.wine/dosdevices/c:/users/me/Start\ Menu/Programs/Spotify.lnk

and it took some experimentation to resolve the issue. Adding an extra back slash solved the problem. (Added back slash in red).


Exec=env WINEPREFIX="/home/me/.wine" wine C:\\\\windows\\\\command\\\\start.exe /Unix /home/me/.wine/dosdevices/c:/users/me/Start\\ Menu/Programs/Spotify.lnk
