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; } ":

By default, tomcat uses an enhanced java.util.logging implementation called JULI, which can be configured at two different levels: Globally, with the ${catalina.base}/conf/logging.properties file. Per web application, with WEB-INF/classes/logging.properties . The configuration file is a normal Java properties file: Logging handlers are specified with the handlers property.
handlers = 1catalina.org.apache.juli.FileHandler, ... The root logger can define its set of handlers using the .handlers property. .handlers = 1catalina.org.apache.juli.FileHandler,... A prefix may be added to handler names. The prefix starts with a digit and ends with a dot ( . ), for example: # 1catalina. is a prefix 1catalina.org.apache.j... System property replacement is performed for property values which contain ${systemPropertyName} . Each handler can have its own specific properties: 3manager.org.apache.juli.FileHandler.level = FINE ... Loggers can define their own...

Resource files under the src/main/resources directory are copied verbatim to the target/classes directory during build. But resources can be filtered by turning on filtering in pom.xml :
<build> <resources> <resource> ... When filtering is turned on, constructs like ${...} are replaced with actual values if they are defined. For example, create a file test.properties : project.stage=${project.stage} The build command " mvn package " simply copies test.properties to target/classes/ . But if you build with: mvn -Dproject.stage=dev package the contents of target/classes/test.properties becomes: project.stage=dev Sometimes you want different resource definitions for different environments, e.g., dev vs. prod. You can achieve that by defining profiles in pom.xml : <profiles> <profile> <id>dev</id> ... In the above, dev is the default profile, prod is defined but not active unless...

Maven repositories are a central part of the Maven build system. Maven resolves dependencies through repositories. There are two types of repositories: local and remote . The local repository stores local build artifacts (when you do mvn install ) and caches artifacts from remote repositories. It is usually located on the local file system at $USER_HOME/.m2/repository . Remote repositories are located on the network and accessed by URLs ( http:// or file:// etc). The central Maven repository is: repo1.maven.org . The Java EE repositories are located at: http://download.java.net/maven/2/ and http://download.java.net/maven/1/ . Remote repositories can also be set up on the company intranet within a company's firewall. The central repository is automatically configured after installation. You can add additional repositories in settings.xml , for example:
<?xml version="1.0" encoding="UTF-8"?> <setting......

By Java documentation , java.endorsed.dirs is used to provide an Endorsed Standards Override Mechanism . Which means, a user can provide newer versions of certain packages than those provided by the JDK. If there are newer implementations of these packages in the directories specified by java.endorsed.dirs , those implementations will be loaded instead of the default ones that come with the JDK. The packages that can be overriden this way are grouped into Endorsed Standards APIs and Standalone Technologies , and are listed in the Java documentation . Roughly speaking the Endorsed Standards APIs include: javax.rmi.CORBA various org.omg.* packages org.w3c.dom various org.xml.sax.* packages Standalone Technologies include: Java API for XML Processing (JAXP), version 1.4 Java Architecture for XML Binding (JAXB), version 2.0 Java API for...
