freenx arrow keys don't work

After reading tons, having no clue, flailing around, on both client and server I did System, Preferences, Keyboard, Layouts, "Evdev-managed keyboard" or similar, and then in the nx session, on the server, I did System, Preference, Keyboard shortcuts, Desktop, Take a screenshot. It was "Print", I pressed "Ctrl+PrtSc", it changed to "Ctrl+Print", and now ALL the nav keys work fine.

JavaFX on ubuntu linux

JavaFX gets a lot of bad rap, but this is mainly due to the difficulty of getting Java plugin working properly on firefox. Once the java firefox plugin is installed properly JavaFX works well. The load time is quick as well. It can be a Flash competitor if only the java browser plugin installation was easier.

I prefer downloading the JDK directly from SUN instead of using apt-get. Once the JDK is installed, all thats needed is to create a symlink.

I install my jdk in /usr/local/jdk

ln -s /usr/local/jdk/jre/plugin/i386/ns7/libjavaplugin_oji.so /usr/lib/firefox/plugins

Restart firefox and

redirect http to https with grails

use a grails filter:
class SecurityFilters {
def filters = {
https(controller: '*', action: '*') {
before = {
if (!request.secure) {
String url = request.requestURL.toString()
String prefix = "http://"
String suffix = ".dispatch"

int startIndex = prefix.size()
def endIndex = url.indexOf(suffix) - 1
def grails = url.indexOf("/grails/")

String body = url[startIndex..grails - 1] + url[grails + 7..endIndex]
String secureHttp = "https://$body"
redirect(url: secureHttp)
return false
}
}
}

empty subject (no subject) in email with grails mail plugin

When sending email using the grails mail plugin, the email subject always ends up empty with (no subject)

this is a known problem. see the link
http://www.nabble.com/Grails-mail-plugin-0.5-:-subject-and-body-always-empty-td20008519.html

The problem happens if you have groovyws-all-0.4.jar in your lib directory. groovyws-all.jar also has javax.mail.* classes packed in there. The fix is as simple unjaring, remove the javax.mail package and rejar it.

hope someone finds this helpful... spent a good half day researching this
