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......

jQuery automatically maps HTML5 custom data attributes to data storage associated with the data() method. Here's an example:
<html>

Contrary to the DD-WRT router database , the Belkin F5D7231-4 v2000 cannot be flashed with TFTP . When I followed the TFTP procedures, I always got TTL=64 , never TTL=100 or TTL=128 , which is supposed to indicate that the router TFTPd is ready. I got network timeout when I tried to send the bin file anyway. The right way to flash the Belkin F5D7231-4 v2000 is to use the binary and Sercomm Utility provided by eko. Simply: Put the router in upgrade mode: unplug router, press reset button and keep it pressed while plugging in the power. Release it when lan leds turn off. Power and Connected led must blink . start the Sercomm Utility select the network interface connected to the router select...

The only explanation of why some Java EE API classes are stripped off methods implementations I can find is this JBos forum post: What's the cause of this exception: java.lang.ClassFormatError: Absent Code? which also provides some workarounds for these crippled API classes. The explanation offered was: When one compiles, they want to run as well. By the way, we have been promoting full set of Java EE APIs which can only be used for compilation - they are stripped off method details. That way, user can't take those artifacts and try to use it in runtime. Honestly, I don't see any logic in those statements. This is the only place any such explanation is offered. Yes only from this JBos forum post! There's no public...

I built a very basic JSF application and deployed to Tomcat 7.0.22, but it failed with this error:
Caused by: java.lang.ClassFormatError: Absent Code... That looks weird and I wasn't able to find a sensible explanation! So I copied the jsf-api-2.1.jar , which was downloaded from the java.net Maven repository by Maven, into a temp folder. And tested it with this simple program: public class ClassFormatErrorTest { public ... I also copied servlet-api.jar from Tomcat's lib folder to the temp folder. Sure enough it failed with the same error: C:\tmp>java -cp .;jsf-api-2.1.jar;servlet-api.jar ... But when I replaced the javax.faces.webapp.FacesServlet class with one I compiled from source, the error disappears! Conclusions: The jar file jsf-api-2.1.jar from java.net Maven repository is good for compilation only (cannot be used...

Copied verbatim from The GNU C Library Manual . When you have finished using a socket, you can simply close its file descriptor with close ; see Opening and Closing Files . If there is still data waiting to be transmitted over the connection, normally close tries to complete this transmission. You can control this behavior using the SO_LINGER socket option to specify a timeout period; see Socket Options . You can also shut down only reception or transmission on a connection by calling shutdown , which is declared in sys/socket.h . Function: int shutdown (int socket, int how) The shutdown function shuts down the connection of socket socket. The argument how specifies what action to perform: 0 - Stop receiving data for this socket....

Alfresco RESTful URLs provided by Web Scripts are extensively documented, but examples are hard to come by. This makes it hard to ramp up for beginners. Here are some examples I tested on 3.4.4 enterprise edition and 4.0a community edition, with the results documented. To list the available scripts:
http://localhost:8081/alfresco/service/index There's a Refresh Web Scripts button at the bottom of the page. If you add a Web Script, you need to click that button in order for the system to know about your addition. To get information about the root folder ( Company Home ): http://localhost:8081/alfresco/service/cmis/p To get information about the folder Data Dictionary : http://localhost:8081/alfresco/service/cmis/p/Data... To get information about the folder Data Dictionary/Space Templates : http://localhost:8081/alfresco/service/cmis/p/Data... You get the idea. To list the children...

From Alfresco wiki :
Script Files
Script files can be stored either on the ClassPath (for example, in alfresco/extension/myscripts ) or in a repository store. Scripts are generally stored in the default repository in the Company Home/Data Dictionary/Scripts location. Scripts in this location can be accessed directly by users via the Execute a script action . Scripts in any repository location can be accessed by any user via REST URL if they have the appropriate read permissions on the script document. Scripts on the ClassPath can be imported into other scripts but not executed directly in the web client.
