Error: No JDK found on PATH, Please correct the SetJavaHome directive or add the directive

If you have seen the following error while trying to execute Oracle SQL Developer:

Error: No JDK found on PATH
Please correct the SetJavaHome directive or add the directive
in /home/barenca/bin/sqldeveloper/sqldeveloper/bin/sqldeveloper.conf or
sqldeveloper-Linux.conf
to point to the JDK installation.

You just need to indicate the J2SDK path in the file sqldeveloper/bin/sqldeveloper.conf and that's it!.

Edit the file ./sqldeveloper/bin/sqldeveloper.conf and add the path of your j2sdk installation (in Linux/unix which java and then follow the symbolic links):

SetJavaHome /usr/lib/jvm/java-6-sun

And that's it!, enjoy it.

Sound Volume keys in IceWM (tested with Latitude D620)

Some days ago I took sometime and I installed Antix 8, not everything is according with the features I was waiting for, but It is OK.

One thing It was missing was the configuration for the Sound Volume keys, so this is what I did for enabling the keys on my Laptop.

Go to the Antix Control Center, click on Edit IceWM settings, click on keys tab and append the following to the file:

key "XF86AudioLowerVolume" amixer -q set Master playback 5-

key "XF86AudioRaiseVolume" amixer -q set Master playback 5+

key "XF86AudioMute" amixer sset Master toggle

Then save the file.

Now click on the statup tab and append the following lines:

xmodmap -e 'keycode 176 = XF86AudioRaiseVolume'

xmodmap -e 'keycode 174 = XF86AudioLowerVolume'

xmodmap -e 'keycode 160 = XF86AudioMute'

Then save the file.

Close the session and It's done!.
