By default Firefox puts a dotted line box around the link or button label when you click them. Sometimes it's annoying and makes your sexy buttons look ugly. You can get rid of the dotted lines for links with outline:none in CSS, but that doesn't work for buttons.

For buttons you need " button::-moz-focus-inner { border: 0; } ":

This note lists some of the different behaviors I found using different JSF implementations. In the simple JSF facelet example, I used Sun's reference implementation version 2.0.0-RC:
<dependency> <groupId>javax.faces</gro... With this version, the DOCTYPE declaration is dropped when the page is rendered. It doesn't matter what DOCTYPE you declare in your templates, the facelet engine simply drops it. The problem with this is, your page is always displayed in quirks mode , despite your intentions to require standards compliant mode. The DOCTYPE problem is fixed in release 2.0.2-FCS . Change the dependency in pom.xml to: <dependency> <groupId>javax.faces</gro... and test again, you'll find that DOCTYPE is faithfully passed over to the browser (view source at browser). You can delete the DOCTYPE declaration in the xhtml template...

This is a simple example to demonstrate the templating power of JSF facelets. If you've used struts tiles before, you'll recognize the simplicity of templating with facelets. I've stripped out everything else except the pages themselves, just to put our focus on facelets. This is a Maven based project, and you need Tomcat (or any servlet container) to run the resulting webapp. To begin with this is the list of files:
./pom.xml ./src/main/webapp/home.xhtml ./src... I left faces-config.xml in there for completeness sake, it may not be needed. The Maven POM ( pom.xml ): <?xml version="1.0" encoding="UTF-8"?> <project... Web app configuration ( WEB-INF/web.xml ): <?xml version="1.0" encoding="UTF-8"?> <web-app... Empty WEB-INF/faces-config.xml : <?xml version="1.0" encoding="UTF-8"?> <!-- Thi... index.jsp is simply a redirect to home.jsf : <% response.sendRedirect("home.jsf"); %>...

Fedora/Redhat List current status (for httpd):
# chkconfig --list httpd Warning: this works only when one of /etc/rc runlevel .d/ K NN name or /etc/rc runlevel .d/ S NN name exists. It exports wrong status when both K and S scripts exist (in which case the status should be enabled). Enable sshd for run levels 2, 3, 5: # chkconfig --level 2,3,5 sshd on Disable sshd for run levels 2, 3, 5: # chkconfig --level 2,3,5 sshd off By default, the on and off options affect only runlevels 2, 3, 4, and 5.

An XML schema is a definition of XML files, in XML. It plays the same role as old-time DTDs. Overall, an XML schema file looks like this:
<schema attributeFormDefault = (qualified | u... The attribute meanings: targetNamespace : The name space targeted by the current schema definition. It can be any URI. id and version : For user convenience, the W3C spec defines no semantics for them. xml:lang : Natural language identifier defined by RFC 3306 . attributeFormDefault and elementFormDefault : Set default values for the form attribute for attribute and element declarations. blockDefault and finalDefault : Set default values for the block and final attributes for attribute and element declarations.

The PHP function array_unique removes duplicate values from arrays. It takes an optional parameter $sort_flags , which can be one of:
SORT_REGULAR : compare items normally (don't change types)
SORT_NUMERIC : compare items numerically
SORT_STRING : compare items as strings
SORT_LOCALE_STRING : compare items as strings, based on the current locale.
Example:
<?php
$a = array(
'1' => 'Apple',
...
Output:
array_unique results:
array(3) {
[1]=>
