JSTL and Expression Language

JavaServer Pages Standard Tag Library (JSTL) is a custom tags collection that executes common functionalities in web applications, including iteration and selection, data formatting, XML manipulation and database access. JSTL allows JSP developers to focus on development specific necessities, instead of reinventing the wheel.

JSTL is composed of:

  • An expression language.
  • Standard actions libraries.
  • Validators (2 validators).

What is Expression Language (EL)?

Expression Language is a simple language based on ECMAScript (also known as JavaScript) and XPath. It provides expressions and identifiers and type conversion.

Expression Language makes easier the access to implicit objects, such as request / response servlet, scope variables and stored objects on JSP scope (page, request, session and application). EL reduces drastically the need of using JSP expressions and scriptlets, increasing web applications maintainability and extensibility.

Expressions

EL expressions are invoked with this syntax: ${expression}. Expressions consist of:

  • Identifiers.
  • Operators.

Apple Now Third-largest U.S. Music Retailer


Apple Inc.'s digital music store iTunes is now the third-largest music retailer in the United States with 10 percent market share, overtaking Amazon.com in the first quarter, according to a survey released on Friday.

The NPD Group report highlights the growing strength of digital music in the U.S. market as physical sales of compact discs continue to slide.

Apple's iTunes is third behind market leader Wal-Mart Stores Inc. with a 15.8 percent share, and Best Buy Co Inc. with a 13.8 percent share, according to the survey of 40,000 people aged 13 and older.

Both of those retailers mostly sell music in the CD format. Online store bestbuy.com has a 1.1 percent market share with sales of both CDs and digital music.

Amazon.com Inc. dropped to fourth with a 6.7 percent share. Its sales increased but not as fast as rivals.More>>

Apple's iPhone casts big shadow on cell industry

If the device—a melding of phone, Web browser and music and video player—is a hit, analysts say it will cut into market share of major phonemakers, including Schaumburg-based Motorola

As if struggling cell phone-maker Motorola Inc. doesn't have enough to worry about: Here comes the iPhone, heir to the mighty iPod, brainchild of tech golden boy Steve Jobs—and riding a tidal wave of hype to boot.

Due in U.S. stores Friday, the iPhone promises to stir up the mobile phone business. Apple Inc.'s first phone isn't expected to take much business from Schaumburg-based Motorola or anyone else in the short term, but it will change the industry landscape nonetheless, analysts say.

"It will not be a financial disrupter, but it will be a psychological disrupter, a research and development disrupter," said Roger Entner, senior vice president of IAG Research's communications sector. "That's because everybody will say [to competitors like Motorola], 'Why can't you do that?' " More>>

Desi Club Torrent - Feel At Home


BitTorrent is a protocol designed for transferring files.

It is peer-to-peer (p2p) in nature, as users connect to each other directly to send and receive portions of the file. However, there is a central server (called a tracker) which coordinates the action of all such peers. The tracker only manages connections, it does not have any knowledge of the contents of the files being distributed, and therefore a large number of users can be supported with relatively limited tracker bandwidth.

The key philosophy of BitTorrent is that users should upload (transmit outbound, also called seeding) at the same time they are downloading (receiving inbound, also called leeching). In this manner, network bandwidth is utilized as efficiently as possible. BitTorrent is designed to work better as the number of people interested in a certain file increases, in contrast to other file transfer protocols.

Read The Rules

GET A CLIENT In order to use BitTorrent you need to download a Bittorrent client This will allow you to grab the files described in the .torrent. There are many clients currently available that can be downloaded for free of the web. Here is some of them:

Read the FAQs
torrent
Usually this refers to the small metadata file you receive from the web server (the one that ends in .torrent.) Metadata here means that the file contains information about the data you want to download, not the data itself. This is what is sent to your computer when you click on a download link on a website. You can also save the torrent file to your local system, and then click on it to open the BitTorrent download. This is useful if you want to be able to re-open the torrent later on without having to find the link again.
In some uses, it can also refer to everything associated with a certain file available with BitTorrent. For example, someone might say "I downloaded that torrent" or "that server has a lot of good torrents", meaning there are lots of good files available via BitTorrent on that server. TRY IT HERE

Apple Launches iTunes Plus


today launched iTunes® Plus—DRM-free music tracks featuring high quality 256 kbps AAC encoding for audio quality virtually indistinguishable from the original recordings—for just $1.29 per song. iTunes Plus is launching with EMI’s digital catalog of outstanding recordings, including singles and albums from Coldplay, The Rolling Stones, Norah Jones, Frank Sinatra, Joss Stone, Pink Floyd, John Coltrane and more than a dozen of Paul McCartney’s classic albums available on iTunes for the first time.

iTunes will continue to offer its entire catalog, currently over five million songs, in the same versions as today—128 kbps AAC encoding with DRM—at the same price of 99 cents per song, alongside the higher quality iTunes Plus versions when available. In addition, iTunes customers can now easily upgrade their library of previously purchased EMI content to iTunes Plus tracks for just 30 cents a song and $3.00 for most albums.

“Our customers are very excited about the freedom and amazing sound quality of iTunes Plus,” said Steve Jobs, Apple’s CEO. “We expect more than half of the songs on iTunes will be offered in iTunes Plus versions by the end of this year.”

“This is a tremendous milestone for digital music,” said Eric Nicoli, CEO of EMI Group. “Consumers are going to love listening to higher quality iTunes Plus tracks from their favorite EMI artists with no usage restrictions.”

With the release of iTunes Plus, customers can now download tracks from their favorite EMI artists without limitations on the type of music player or number of computers that purchased songs can be played on. iTunes is also offering customers a simple, one-click option to easily upgrade their library of previously purchased EMI content to the iTunes Plus versions. EMI music videos are now also available in iTunes Plus versions with no change in price. iTunes Plus songs purchased from the iTunes Store will play on all iPods, Mac® or Windows computers, widescreen TVs with Apple TV™ and soon iPhones, as well as many other digital music players.

The iTunes Store features the world’s largest catalog with over five million songs, 350 television shows and over 500 movies. The iTunes Store has sold over 2.5 billion songs, 50 million TV shows and over two million movies, making it the world’s most popular online music, TV and movie store.

With Apple’s legendary ease of use, pioneering features such as integrated podcasting support, iMix playlist sharing, seamless integration with iPod® and the ability to turn previously purchased songs into completed albums at a reduced price, the iTunes Store is the best way for PC and Mac users to legally discover, purchase and download music and video online.

Apple ignited the personal computer revolution in the 1970s with the Apple II and reinvented the personal computer in the 1980s with the Macintosh. Today, Apple continues to lead the industry in innovation with its award-winning computers, OS X operating system and iLife and professional applications. Apple is also spearheading the digital media revolution with its iPod portable music and video players and iTunes online store, and will enter the mobile phone market this year with its revolutionary iPhone.

iPhone set to ring up strong results for Apple


NO CONSUMER device has stirred the worldwide interest to match Apple's iPhone, due to go on sale in the US on June 29.

Sony's PlayStation and Microsoft's Xbox 360 pale beside it. Even the phenomenally successful iPod did not gain celebrity status for at least a year after it was launched in October 2001.

To judge by the furore, iPhone is the most desired device on the planet, even though its $US500 ($A590) price tag is about five times more than average US mobile phone prices.

Even in Australia, which is not expected to see the iPhone on sale until late next year or early 2009, interest is keen.

A lot of iPod technology and design is in the iPhone, which may account for the fever of interest surrounding it because in the music-player market it is most desired, works well and is seen as a symbol of coolness.

The fact that Apple has not until now ventured into the highly competitive mobile phone market and, in that sense has no experience in this area, has no bearing on the issue; nor that Apple expects to sell only 10 million iPhones where Nokia, Ericsson and Motorola each probably will sell 300 million of their phones this year.

Expectations of success have galvanised US sharemarkets and Apple's stock is now at a high of $US127, having stacked on more than $US25 in the past month.

Gene Munster, of US analyst firm, Piper Jaffray, says Apple's share price could go to $US160 and that, with European sales beginning at the end of next year, the company will sell 45 million iPhones in 2009.

So what makes the iPhone so sexy?

It is a highly innovative touch-screen mobile phone, media player and wireless internet gadget using 802.11g technology, otherwise called wi-fi and available in thousands of areas all over the world.

Other phones have similar features, but none have quite the finesse of the iPhone. Even the touch-screen is different, and the device uses the Macintosh computer operating system.

It is beautiful to see and great fun to use. I have had one in my hand and made a call on it; to Steve Jobs, Apple's CEO (but he did not answer).

Munster estimates iPhone's price will halve in a year and then capture about 7 per cent of the North American handset market and about 3 per cent of the world mobile phone market.

Motorola's RAZR phone, one of the most popular of recent models, sold 65 million in 12 months after its launch in 2004.

Other analysts, including Jonathan Hoopes, of ThinkEquity Partners, points to the sales curve of the iPod. It sold 187,000 units in its first six months, from October 2001 to April 2002. It did nearly half a million in the next 12 months and 2.18 million the following year. Apple expects to ship 40 million iPhones in 2009.

Forrester Research analyst Charles Golvin expects Apple will continue to develop the iPhone, expanding its memory from 4 gigabyte and adding other technology, including, possibly, WiMAX that would improve wireless internet access.

The other sales-promoting aspect is that the iPhone incorporates what amounts to an iPod nano. Thus, if you add the cost of a mobile to the cost of an iPod, you get roughly the price of an iPhone, plus internet access.

Apple and Google - Partnership Next Week?


With Apple’s WorldWide Developer Conference (WWDC) on schedule for next week, this is the time for rumors to come flying. The latest one and highly-probable one: Apple and Google partnering up on updating Apple’s .Mac service.

Apple’s .Mac service provides consumers with one gigabyte of shared email/web storage that users can back their own documents up to and also host websites on. They also provide online calendar, synchronizing of bookmarks to multiple computers, and more, for $99/year. While this is all put on by Apple and seems like a good round-up features, Google, the search-engine giant, has most, if not all of these features for free and are in some cases better than what Apple currently provides. Google’s GMail service provides users with a continuously growing amount of storage space for their email, as well as Google PageBuilder to create your own site on, Google Calendar, and many other features that Apple provides.

Apple has been bashed for not updating these features to catch up with competitors, but that may change. Wired is reporting that Apple and Google may partner up with each other to update the .Mac service to make it more comparable to other solutions. In an interview with Eric Schmidt, CEO of Google and also an Apple board member, he believed that this was bound to happen. “We’re a perfect back end to the problems that they’re trying to solve. They have very good judgment on user interface and people. But they don’t have this supercomputer (that Google has), which is the data centers. What they have is a manufacturing business that’s doing quite well.”

This could be a hint to an upcoming re-release of the .Mac service. Also, when Steve Jobs, CEO of Apple, was asked at the D Conference last week, he said that they “will make up for lost time in the very near future” for their putting off .Mac upgrade. We will see how this all folds out on Monday, June 11 at the WWDC keynote speech.

Sun CEO spills Apple Leopard secret

Apple may have a jones for secrecy, but that doesn't mean it can keep its partners quiet.

On stage Wednesday in Washington, D.C., Sun Microsystems CEO Jonathan Schwartz revealed that his company's open source ZFS file system will replace Apple's long-used HFS+ in Mac OS X 10.5, a.k.a. "Leopard," when the new operating system ships this fall.

"This week, you'll see that Apple is announcing at their Worldwide Developers Conference that ZFS has become the file system in Mac OS X," said Schwartz.

ZFS (Zettabyte File System), designed by Sun for its Solaris OS but licensed as open source, is a 128-bit file storage system that features, among other things, "pooled storage," which means that users simply plug in additional drives to add space, without worrying about such traditional storage parameters as volumes or partitions.

"[ZFS] eliminates volume management, it has extremely high performance.... It permits the failure of disk drives," crowed Schwartz during a presentation focused on Sun's new blade servers. Apple's operating system currently relies on HFS+ (Hierarchical File System Plus), a 1998 extension of 1985's HFS.

ZFS was touted by many as a possible successor to HFS+ last summer, immediately after Apple's CEO Steve Jobs first showed off Time Machine, the new backup feature planned to debut in Leopard.

In the intervening months, however, the ZFS-Time Machine connections were downplayed or dismissed by most observers. Even today, after Schwartz talked up ZFS, bloggers seemed skeptical about the file system's place in Leopard.

"I'll stick to my prediction that Apple, as with HFS+, will put ZFS on OS X Server first before bringing it out later for the great unwashed," said Robin Harris on his StorageMojo blog.

Most objections centered around the short time between now and Leopard's October release, and the implications of such a major makeover. Others at Sun, however, seemed to confirm that ZFS would be the default file system.

"Jonathan noted that Apple will announce this week that the ZFS file system from OpenSolaris will become Apple's new default file system," said Marc Hamilton, Sun's director of technology for global education and research, on his company blog.

"So how does that help Sun? It is pretty simple: Now every Apple developer will know ZFS and how to use it on our SunFire x4500 storage server and other Sun products." A Sun spokeswoman would not confirm or deny that ZFS would be Mac OS X 10.5's default file system.

"I can't tell you anything more than what Jonathan [Schwartz] said today," she said.

Apple does not comment on unannounced products or product features. Schwartz may have unwittingly stolen some of Jobs' thunder for next week, since Apple watchers expect the Apple CEO to tout Leopard -- especially features previously not made public -- during his WWDC keynote next Monday.

Apples iPhone: Hype or Heavyweight?
