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.

Sergey Brin - Google Founder


Sergey was born in Moscow, Russia, to a Jewish family, the son of a mathematician and economist. In 1979, when Sergey was six, his family emigrated to the United States. Brin attended grade school at Paint Branch Montessori School in Adelphi, Maryland, but he received further education at home; his father Michael Brin, a professor in the department of mathematics at the University of Maryland, nurtured his interest in mathematics and his family helped him retain his Russian language skills. In September 1990, after having attended Eleanor Roosevelt High School, Sergey enrolled in the University of Maryland, College Park to study Computer Science and Mathematics, where he received his Bachelors of Science in May 1993 with high honors. After graduating from Maryland, Sergey received a graduate fellowship from the National Science Foundation, which allowed him to study for his masters degree in Computer Science at Stanford University. Sergey received his masters degree in August 1995 ahead of schedule in the process of his Ph.D. studies. Although he is still enrolled in the Stanford doctoral program, Sergey has suspended his Ph.D. studies indefinitely while he is working at Google. Sergey also received an honorary MBA from the Instituto de Empresa.

Sunil Mittal

Sunil MittalEven in Lutyens' Delhi, there is no more exclusive address than Amrita Shergill Marg. And among the mansions that line this leafy road is one that stands apart from the rest.

Created as a colonial house, it was built from scratch by a virtually unknown architect, Sarabjeet Singh, complete with its high corniced ceilings, a quaint English library (that took two years to build) and large gardens dotted with lush palms.

Unlike many of its neighbours in that prestigious neighbourhood, it hasn't featured in any design journal yet. But it's one house Delhi can't stop talking about.

For 47-year-old Sunil Bharti Mittal, the Ludhiana boy who started out as a bicycle parts dealer and lived in New Delhi's upper middle class Azad Apartments, it has been a long journey to what is ostensibly the city's poshest, largest house.

As the country's undisputed telecom czar, he straddles a Rs 8,000-plus crore (Rs 80 billion-plus) empire which, like his house, he built from scratch.

But already Mittal is charting a new course. Not content with being telecom's tycoon, he is giving shape to a new thrust in non-telecom businesses. A decade from now, he reckons, telecom may no longer be the largest slice in the Bharti pie.

Over the next three months Mittal hopes to float an equity fund with a large corpus (the extent of which is still being decided, though Mittal says money is not a problem), that will be used to fund new businesses in emerging areas, to be run by others.

This last is important because it points to the direction -- and role -- Mittal is carving for himself.

As the group has limited management time and can't get into too many new businesses on its own, it will fund others instead. "We can invest anything up to 74 per cent, or only 26 per cent, function as an incubator for entrepreneurs with new ideas. . . the scope is endless."

This is different from what the group is doing now. For instance, it has a stake in the Bank of Punjab, "but it is a one-off deal and not structured," Mittal says.

For a man who intends to step down as executive chairman of Bharti Televentures -- his telecom empire -- when he turns 50 three years down the line, the push into new initiatives is hardly surprising.

Taking his cue from the Tata structure, the new Bharti structure envisages each business being run independently by a CEO with the board looking only at governance issues that cut across companies: group strategy, finance and HR, for instance.

Mittal sees himself sliding into a non-executive role by the time he's 49, so he has a year to mentor those occupying the new roles.

The new ventures? Mittal is taken with agriculture, and airport infrastructure (he's bid for the privatisation of Delhi airport). And to fund some of it, he's willing to sell part of his family equity in the telecom business, though he doesn't visualise himself as a minority stake holder.

But is that the only reason he is calling it quits? Or does he want to relax after a hectic life in business and join politics? He's not giving anything away yet, saying his life, in fact, has become more hectic.

He hardly gets to play golf, though he ensures that he keeps fit by jogging four times a week in Lodi Gardens, just a stone's throw away from home.

"I have the luxury of stepping down at 50," he says. "Others do it later on, some continue to run. After all, what is Mr Tata doing in his sixties? At one level you can say he is running every business, at another level you can say he is running nothing."

Even on politics, he won't let the cat out of the bag yet. "I am not averse to politics," he says, "but neither am I enamoured of it. Whether my public life will meander into politics, I don't know."

What he does know is that he will play a larger role in public life (particularly primary education for the underprivileged, and public policy) through the Bharti Foundation -- the corpus for which will soon be hiked considerably: it has already spent over Rs 30 crore (Rs 300 million).

Among structures he is studying are those like Ford Foundation and the Rand Corporation to understand the nuances of institution building.

Clearly, the Bharti empire is going to look different with each passing year. While he's reluctant to share the percentage of revenues he expects from the non-telecom businesses, it's clear he's looking forward to some hands-on action.

"In 1996-97, I used to run Delhi's mobile business personally, though I had CEOs. Today, that has disappeared in a cloud of Airtel circles. I go to my Delhi office once in two-three years. Ten years down the line the telecom business will be what Delhi was 10 years ago." Mittal says it will be one of the many businesses that they would own.

His immediate priority is to get the succession plan rolling, and a key ingredient is to delegate more powers to those running the various businesses.

For instance, Mittal has two presidents for the telecom operation: mobiles and fixed line. All decisions on operations are taken at the president's office, while 25 per cent of strategy decisions are taken at the corporate office by Mittal and his two joint managing directors (including brother Rajan Mittal). Soon these powers too will be relinquished to the presidents.

Already the frequency of management council meetings headed by him are becoming infrequent: once in two weeks currently, and maybe once in four weeks as powers are delegated.

Regulatory and procurement decisions have been shifted from the corporate office to the two divisions. Mittal says once he relinquishes executive power, the presidents could move up to become managing directors running the business.

Structurally, he refers once again to the Tata operations. "Mr Ramudorai runs TCS independently, and Mr Muthuraman runs Tata Steel, but when it comes to a TCS IPO, it is Ratan Tata and Ishat Hussain (the finance director in Tata Sons) who walk the aisle."

Similarly, in Bharti, independent CEOs will run businesses and will relate to either of the joint MDs in the corporate office when it comes to key issues like financing, brand or group strategy.

For instance, says Mittal: "If any of them wants to raise resources, they will come to the corporate office as we have the skill sets to raise money at 5.5 per cent in the global market, which they don't have."

More importantly, given the structure of Bharti Televentures, he does not see his sons joining the company. What he does envision is consolidation of these two businesses into one in the immediate future -- to be run by a CEO.

But there are some attempts at consolidation even here -- for instance, the IT department has been combined, and attempts to consolidate distribution are being made with both companies cross-selling each other's products.

Others remain sceptical of what Mittal sees as his renunciation of control at Bharati Televentures. They see the company as a family and close associate run business.

"Who do you see at the helm of affairs apart from Sunil? It's only Rajan, or Akhil Gupta, who have been with him from the beginning. The limelight is still on them, so I don't see any cultural changes at all," says one observer.

And according to a senior member of the Cellular Operators Association of India who has worked with him for years, "He is too top heavy, so there is duplication of work and tensions, though that might be part of his management style. But I can't think of him really loosening control over his companies."

Whether he lets go or not, a telecom managment specialist says, "He is doing the right thing, he is de-risking his business portfolio, especially with the telecom business giving him good cash flows.

There is always a risk that a new innovation could throw your telecom business model out of gear, so it not that unusual for him to cash out partly from telecom and de-risk by investing in other businesses."

Of the two new businesses, the more ambitious gamble for Mittal will be his foray into agriculture. He says it has the potential of becoming a bigger business than telecom, but warns that it's a tough nut to crack, especially as the company has decided to sell fresh vegetables and not processed foods.

The learning curve is underway: the company wanted to send fresh grapes from Sangli, in Maharashtra, to Holland, but they were plagued by a pest attack and delay in shipping.

In Punjab, the main challenge is how to ship fresh vegetables from a state where there are no ports or many cold chains. Then there are regulatory issues to be tackled. But for starters, the first model farm is being kicked off in Ludhiana in a few months.

Mittal will eventually look into retailing of the group's products by building a franchise chain. In fact, the initial programme was to set up a retail chain before he realised the need to set up the back end first, as fresh products were not available.

His other venture arises out of a passion for developing infrastructure for railways and airports. With no hope of the railways being privatised in the next few decades, he's reserved his attention for airports -- since he feels he missed the bus in two other industries that fascinate him.

"I like the airline business and the media business, but Naresh Goyal (Jet) and Subhash Chandra (Zee) started at the same time as us and built these businesses. Today they are entrenched, and it doesn't make sense for us to enter there," he says.

And so his hope of building world-class airports instead. Mittal reels out reasons why the airport project is close to his heart: it will need $1 billion in investment (and Bharti has proven expertise in putting together large infrastructure projects); over 50 million passengers will use the service (and Bharti understands customer care); and in Changi Airport Authority, Bharti has the best possible partnership.

But he is aware that it might not be a scaleable business, or at least not bigger than telecom. Says Mittal: "We expect revenues of $150 million that might quadruple, but it is not scaleable. In telecom, on the other hand, we are closing at Rs 8,000 crore (Rs 80 billion) and could well become Rs 20,000 in a few years. That is the difference.''

But nothing is final on the airport sector. Says an aviation watcher: "He has a 50:50 chance of getting Delhi. There are others in the race who have political clout and good credentials, so the going won't be easy unless he joins hands with them."

Whether he gets the airport project or not, there's no denying Mittal's networking skills. A few weeks ago he was in Cannes attending the GSM Association meet.

Says a senior telecom functionary who was with him: "Despite his hectic schedule, he spent four days and gave a a talk on the challenges to get to the next one billion mobile customers. He was the only Indian private sector telecom CEO who spent this kind of time on networking." That is a clear reflection of a winner.

Jeff Bezos - Founder and CEO, Amazon.com

Jeffrey P. Bezos was born in Albuquerque, New Mexico. His mother's ancestors were early settlers in Texas, and over the generations had acquired a 25,000 acre ranch at Cotulla. Jeffrey's maternal grandfather was a regional director of the Atomic Energy Commission in Albuquerque. He retired early to the ranch, where Jeffrey spent most summers of his youth, working with his grandfather at the enormously varied tasks essential to the operation. At an early age, he displayed a striking mechanical aptitude. Even as a toddler, he asserted himself by dismantling his crib with a screwdriver.

Jeffrey was born when his mother was still in her teens, and her marriage to his father lasted little more than a year. She remarried when Jeffrey was four. Jeffrey's stepfather, Mike Bezos, was born in Cuba; he escaped to the United States alone at age 15, and worked his way through the University of Albuquerque. When he married Jeffrey's mother, the family moved to Houston, and Mike Bezos became an engineer for Exxon.

Jeff Bezos Biography Photo
Jeffrey showed intense and varied scientific interests at an early age. He rigged an electric alarm to keep his younger siblings out of his room and converted his parents' garage into a laboratory for his science projects. The family moved to Miami, Florida, where Jeffrey attended high school. In high school, Jeffrey fell in love with computers and was valedictorian of his class. He entered Princeton University planning to study physics, but soon returned to his love of computers, and graduated with a degree in computer science and electrical engineering.

After graduation, Jeff Bezos found employment on Wall Street, where computer science was increasingly in demand to study market trends. His went to work at Fitel, a start-up company that was building a network to conduct international trade. He stayed in the finance realm with Bankers Trust, rising to a Vice Presidency.

At D. E. Shaw, a firm specializing in the application of computer science to the stock market, Bezos was hired as much for his overall talent as for any particular assignment. While working at Shaw, Jeff met his wife, Mackenzie, also a Princeton graduate. He rose quickly at Shaw, becoming a senior Vice President, and looked forward to a bright career in finance, when he made a discovery that changed his life, and the course of business history.

The Internet was originally created by the Defense Department to keep its computer networks connected during an emergency, such as natural catastrophe or enemy attack. Over the years, it was adopted by government and academic researchers to exchange data and messages. In 1994, there was still no Internet commerce to speak of. One day that spring, Jeffrey Bezos observed that Internet usage was increasing by 2300 percent a year. He saw an opportunity for a new sphere of commerce, and immediately began considering the possibilities.

In typically methodical fashion, Bezos reviewed the top 20 mail order businesses, and asked himself which could be conducted more efficiently over the Internet than by traditional means. Books were the commodity for which no comprehensive mail order catalogue existed, because any such catalogue would be too big to mail; perfect for the Internet, which could share a vast database with a virtually limitless number of people.

He flew to Los Angeles the very next day to attend the American Booksellers' Convention and learn everything he could about the book business. He found that the major book wholesalers had already compiled electronic lists of their inventory. All that was needed was a single location on the Internet, where the book-buying public could search the available stock and place orders directly. Bezos's employers weren't prepared to proceed with such a venture, and Bezos knew the only way to seize the opportunity was to go into business for himself. It would mean sacrificing a secure position in New York, but he and his wife, Mackenzie, decided to make the leap.

Jeff and Mackenize flew to Texas on Independence Day weekend and picked up a 1988 Chevy Blazer (a gift from Mike Bezos) to make the drive to Seattle, where they would have ready access to the book wholesaler Ingram, and to the pool of computer talent Jeff would need for his enterprise. Mackenzie drove while Jeff typed a business plan. The company would be called Amazon for the seemingly endless South American river with its numberless branches.

They set up shop in a two-bedroom house, with extension cords running to the garage. Jeff set up three Sun microstations on tables he'd made out of doors from Home Depot for less than $60 each. When the test site was up and running, Jeff asked 300 friends and acquaintances to test it. The code worked seamlessly across different computer platforms. On July 16, 1995, Bezos opened his site to the world, and told his 300 beta testers to spread the word. In 30 days, with no press, Amazon had sold books in all 50 states and 45 foreign countries. By September, it had sales of $20,000 a week. Bezos and his team continued improving the site, introducing such unheard-of features as one-click shopping, customer reviews, and e-mail order verification.

The business grew faster than Bezos or anyone else had ever imagined. When the company went public in 1997, skeptics wondered if an Internet-based start-up bookseller could maintain its position once traditional retail heavyweights like Barnes and Noble or Borders entered the Internet picture. Two years later, the market value of shares in Amazon qwas greater than that of its two biggest retail competitors combined, and Borders was striking a deal for Amazon to handle its Internet traffic.

From the beginning, Bezos sought to increase market share as quickly as possible, at the expense of profits. When he disclosed his intention to go from being "Earth's biggest bookstore" to "Earth's biggest anything store," skeptics thought Amazon was growing too big too fast, but a few analysts called it "one of the smartest strategies in business history."

Jeff had told his original investors there was a 70 percent chance they would lose their entire investment, but his parents signed on for $300,000, a substantial portion of their life savings. "We weren't betting on the Internet," his mother has said. "We were betting on Jeff." By the end of the decade, as six per cent owners of Amazon.com, they were billionaires. The stock has split three times, and to this day, about a third of the shares are held by members of the Bezos family.

Jeff Bezos Biography Photo
Through each round of expansion, Jeff Bezos continually emphasized the "Six Core Values: customer obsession, ownership, bias for action, frugality, high hiring bar and innovation." "Our vision," he said, "is the world's most customer-centric company. The place where people come to find and discover anything they might want to buy online." Amazon moved into music CDs, videos, toys, electronics and more. When the Internet's stock market bubble burst, Amazon re-structured, and while other dot.com start-ups evaporated, Amazon was posting profits.

In October 2002, the firm added clothing sales to its line-up, through partnerships with hundreds of retailers, including The Gap, Nordstrom, and Land's End. Amazon shares its expertise in customer service and online order fulfillment with other vendors through co-branded sites, such as those with Borders and Toys 'R Us, and through its Amazon Services subsidiary. In September, 2003, Amazon announced the formation of A9, a new venture aimed at developing a commercial search engine that focuses on e-commerce web sites. At the same time, Amazon launched an online sporting goods store, offering 3,000 different brand names. Amazon.com ended 2002 with annual sales over $3.9 billion, a figure analysts expect to grow by roughly 17 percent in 2003.

Today, Jeff Bezos and Mackenzie live north of Seattle and are increasingly concerned with philanthropic activities. "Giving away money takes as much attention as building a successful company," he has said.

Larry Ellison

Lawrence J. Ellison was born in the Bronx, New York. At nine months, he contracted pneumonia, and his unmarried 19 year-old mother gave him to her great aunt and uncle to raise. Lawrence was raised in a two-bedroom apartment on the South Side of Chicago. Until he was twelve years old he did not know that he was adopted. His great uncle and adoptive father had lost his real estate business in the Great Depression and made a modest living as an auditor for the public housing authority. As a boy, Larry Ellison showed an independent, rebellious streak and often clashed with his adoptive father. He showed a strong aptitude for math and science, and was named science student of the year at the University of Illinois. During the final exams in his second year, Ellison's adoptive mother die, and he dropped out of school. He enrolled at the University of Chicago the following fall, but dropped out after the first semester. his father was now convinced he would never make anything of himself, but Ellison had learned the rudiments of computer programming in Chicago and took this skill with him to Berkeley, California, arriving with just enough money for fast food and a few tanks of gas.

For the next eight years he bounced from job to job, working as a technician for Fireman's Fund, Wells Fargo bank and began working as a programmer with large databases at Ampex. At Ampex he built a large database for the CIA, code name: Oracle.

Larry Ellison Biography Photo
In 1977, Ellison and his former supervisor from Ampex, Robert Miner, founded Software Development Labs. They supported themselves by consulting for an assortment of corporate clients, when Ellison read a paper called "A Relational Model of Data for Large Shared Data Banks" by E. F Codd, describing a concept Codd had developed at IBM. IBM had seen no commercial potential in the concept of a Structured Query Language (SQL), but Ellison and his partner did. They created a database program compatible with both mainframe and desktop computer systems, renamed their company Oracle, and found their first customers for the database program, Wright Patterson Air Force Base and the CIA. In 1980, Oracle had only eight employees, and revenues were less than $1 million, but the following year, IBM itself adopted Oracle's SQL for its mainframe systems and for the next seven years, Oracle's sales doubled every year. The million dollar company was becoming a billion dollar company.

Oracle went public in 1986, raising $31.5 million with its initial public offering, but the firm's zealous young staff for the rapidly expanding firm habitually overstated revenues, and in 1990 the company posted its first losses. Oracle's market capitalization fell by 80 percent and the company appeared to be on the verge of bankruptcy. Ellison bit the bullet and replaced much of the original senior staff with more experienced managers. For the first time, he delegated the management side of the business to professionals, and channeled his own energies into product development. The newest version of the database program was a solid success and in only two years the company's stock had regained much of its previous value.

Even as Oracle's fortunes rose again, Ellison suffered a series of personal mishaps. Long an enthusiast of many sports and outdoor activities, in rapid succession Ellison suffered serious injuries while body surfing and mountain biking. Ellison survived major surgery, and continued to race his 78-foot yacht and practice aerobatics in his private jet.

Oracle's fortunes continued to rise throughout the 1990s. America's banks, airlines, automobile companies and retail giants all depend on Oracle's database programs. Oracle has benefited hugely from the growth of electronic commerce; its net profits increased by 76 percent in a single quarter of the year 2000. As the stocks of other high tech companies fluctuated wildly, Oracle held its value, and its largest shareholder, founder and CEO Larry Ellison, had come very close to a long-cherished goal, surpassing Microsoft's Bill Gates to become the richest man in the world.
