In this example I'll add a parameter to a facelets template. The example contains three tabs, each tab points to a different page. The tab control is shared among all pages, therefore, it is put in the template.
Starting from the simple facelet example , make these additions:
Create a new template WEB-INF/templates/tabs.xhtml :
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Stric...
Add a page for the about tab ( about.xhtml ):
<?xml version="1.0" encoding="UTF-8"?>
<ui:comp...
Add a page for the news tab ( news.xhtml ):
<?xml version="1.0" encoding="UTF-8"?>
<ui:comp...
Add a page for the partner tab ( partner.xhtml ):
<?xml version="1.0" encoding="UTF-8"?>
<ui:comp...
Build and re-deploy the application. Launch the browser and load page http://localhost:8080/facelet-demo/about.jsf .

The PHP function file_get_contents reads the entire contents of a file into a string, while the function file reads a file into an array.
file_get_contents('filename') is equivalent to implode('', file('filename')) :
<?php
// reads entire file into array, one elem...

The String.format() method provides versatile formatting capabilities. This tutorial tries to present these capabilities in a accessible manner. The format string A format string can contain zero, one, or more format specifiers . The general form of a format specifier is:
%[argument_index$] [flags] [width] [.precision]co... where things in square brackets are optional, and conversion is a character indicating the conversion to be applied to the corresponding variable value. The only required characters in the format specifier is the percent sign % and the conversion character. A simple example: public static void simpleFormat() { System.out... The Argument index The argument index is specified by a number, terminated by the dollar sign $ . The same argument may be repeated multiple times in a format string. Unindexed...

If Command Extensions are enabled (which is enabled by default), then there are several dynamic environment variables that can be expanded but which don't show up in the list of variables displayed by SET . These variable values are computed dynamically each time the value of the variable is expanded (but see example below). If the user explicitly defines a variable with one of these names, then that definition will override the dynamic one described below: %CD% - expands to the current directory string. %DATE% - expands to current date using same format as DATE command. %TIME% - expands to current time using same format as TIME command. %RANDOM% - expands to a random decimal number between 0 and 32767. %ERRORLEVEL% - expands to the...

Presumably this should change the log level for the console appender (STDOUT) to DEBUG. However, this change alone does not work. It should be used in combination with the system property jboss.server.log.threshold .
Either add -Djboss.server.log.threshold=DEBUG to JAVA_OPTS in bin\run.conf.bat :
rem # JVM memory allocation pool parameters - modi...
or set it from the command line:
bin\run -Djboss.server.log.threshold=DEBUG

It seems that the key to aligning a checkbox with its label lies in the line-height property of the label. This simple HTML snippet aligns well:
<!DOCTYPE HTML> <html> <head> <style typ... which is rendered like this: Change the font size of the label to 12px throws off the alignment: label.checkbox { font-size: 12px; di... In case 1, the height of the checkbox is 13px with 3px top and bottom margin, for a total of 19px , which is exactly the height of the label div. As can be seen from Firebug : Checkbox layout Label layout In case 2, the height of the label div shrinks to 15px , while the height of the checkbox remains the same: Checkbox layout Label layout And...
