Xbox 360

The Xbox 360 is the second video game console produced by Microsoft, and the successor to the Xbox. 

The Xbox 360 competes with Sony's PlayStation 3 and Nintendo's Wii as part of the seventh generation of video game consoles. 

As of January 2011, there are over 50 million Xbox 360 consoles worldwide.

The Xbox 360 was officially unveiled on MTV on May 12, 2005, with detailed launch and game information divulged later that month at the Electronic Entertainment Expo (E3). The console sold out completely upon release in all regions except in Japan.

Some major features of the Xbox 360 are its integrated Xbox Live service that allows players to compete online, download arcade games, game demos, trailers, TV shows, music and movies and its Windows Media Center multimedia capabilities. The Xbox 360 also offers region specific access to third-party media streaming services such as Netflix and ESPN in the US or Sky Player in the UK.

At their E3 presentation on June 14, 2010, Microsoft announced a redesigned Xbox 360 that would ship on the same day The redesigned console is slimmer than the previous Xbox 360 model and features integrated 802.11 b/g/n Wi-Fi, TOSLINK S/PDIF optical audio output, 5 USB 2.0 ports (compared to the 3 from older versions) and a special AUX port. 

Older models of the Xbox 360 have since been discontinued. The first new console to be released features a 250 GB hard drive, while a later, less expensive SKU features 4 GB internal storage.

With the announcement of the Xbox 360 S, Microsoft have said that they believe that the console is only mid-way through its life-cycle and will continue through 2015. In 2009, IGN named the Xbox 360 the sixth greatest video game console of all time, out of a field of 25

Enterprise JavaBeans

Enterprise JavaBeans (EJB) is a managed, server-side component architecture for modular construction of enterprise applications.

The EJB specification is one of several Java APIs in the Java EE specification. EJB is a server-side model that encapsulates the business logic of an application. The EJB specification was originally developed in 1997 by IBM and later adopted by Sun Microsystems (EJB 1.0 and 1.1) in 1999 and enhanced under the Java Community Process as JSR 19 (EJB 2.0), JSR 153 (EJB 2.1), JSR 220 (EJB 3.0) and JSR 318 (EJB 3.1).

The EJB specification intends to provide a standard way to implement the back-end 'business' code typically found in enterprise applications (as opposed to 'front-end' interface code). Such code was frequently found to address the same types of problems, and it was found that solutions to these problems are often repeatedly re-implemented by programmers. Enterprise JavaBeans were intended to handle such common concerns as persistence, transactional integrity, and security in a standard way, leaving programmers free to concentrate on the particular problem at hand.

Accordingly, the EJB specification details how an application server provides:

• Transaction processing
• Integration with the Persistence services offered by the Java Persistence API (JPA)
• Concurrency control
• Events using Java Message Service
• Naming and directory services (JNDI)
• Security (Java Cryptography Extension (JCE) and JAAS)
• Deployment of software components in an application server
• Remote procedure calls using RMI-IIOP.
• Exposing business methods as Web Services.

Additionally, the Enterprise JavaBean specification defines the roles played by the EJB container and the EJBs as well as how to deploy the EJBs in a container. Note that the current EJB specification does not detail anymore how an application server provides persistence (a task delegated to the JPA specification), but instead details how business logic can easily integrate with the persistence services offered by the application server.

Java Server Faces

JavaServer Faces (JSF) is a Java-based Web application framework intended to simplify development integration of web-based user interfaces.

JSF is a request-driven MVC web framework based on component driven UI design model, using XML files called view templates or Facelets views. Requests are processed by the FacesServlet, which loads the appropriate view template, builds a component tree, processes events, and renders the response (typically HTML) to the client. 

The state of UI components (and some other objects) is saved at the end of each request (called stateSaving (note: transient true)), and restored upon next creation of that view. Several types of state-saving are available, including Client-side and Server-side state saving.

 Out of the box, JSF 1.x uses JavaServer Pages (JSP) for its display technology, but can also accommodate other technologies (such as XUL and Facelets). JSF 2 uses Facelets by default for this purpose. Facelets is a more efficient, simple, and yet more powerful view description language (VDL).

SQL injection

SQL injection is a code injection technique that exploits a security vulnerability occurring in the database layer of an application.

The vulnerability is present when user input is either incorrectly filtered for string literal escape characters embedded in SQL statements or user input is not strongly typed and thereby unexpectedly executed.

It is an instance of a more general class of vulnerabilities that can occur whenever one programming or scripting language is embedded inside another. SQL injection attacks are also known as SQL insertion attacks.






This form of SQL injection occurs when user input is not filtered for escape characters and is then passed into an SQL statement. This results in the potential manipulation of the statements performed on the database by the end-user of the application.

The following line of code illustrates this vulnerability:

statement = "SELECT * FROM `users` WHERE `name` = '" + userName + "';"

This SQL code is designed to pull up the records of the specified username from its table of users. However, if the "userName" variable is crafted in a specific way by a malicious user, the SQL statement may do more than the code author intended. For example, setting the "userName" variable as

' or '1'='1

Or using comments to even block the rest of the query:

' or '1'='1';/*'

renders this SQL statement by the parent language:

SELECT * FROM `users` WHERE `name` = '' OR '1'='1';
