Software reverse engineering involves reversing a program's machine code (the string of 0s and 1s that are sent to the logic processor) back into the source code that it was written in, using program language statements.
Software reverse engineering is done to retrieve the source code of a program because the source code was lost, to study how the program performs certain operations, to improve the performance of a program, to fix a bug (correct an error in the program when the source code is not available), to identify malicious content in a program such as a virus or to adapt a program written for use with one microprocessor for use with another. Reverse engineering for the purpose of copying or duplicating programs may constitute a copyright violation. In some cases, the licensed use of software specifically prohibits reverse engineering.

Acessing Printer using jsp page
Those who like or need to access Printer from there jsp page.they have to setup Printer.Next from there jsp page they have to put the following code for the button implementation.

Functional Programming Vs Procedural Programming
Functional Programming
Functional programming should not be confused with procedural programming. Neither is it like object oriented programming. It is something different. Not radically so, since the concepts that we will be exploring are familiar programming concepts, just expressed in a different way. The philosophy behind how these concepts are applied to solving problems is also a little different.
Functional programming is all about expressions. In fact another way to describe Functional Programming might be to term it expression oriented programming since in Functional Programming everything reduces to an expression. You should recall that an expression is a collection of operations and variables that results in a single value. Thus x == 8 is a Boolean expression. 3 + (9-Y) is an arithmetic expression. And "Hello".uppercase() is a string expression. The latter is also a function call (Or more strictly a method call) on the string object "Hello" and, as we shall see, functions are very important in Functional Programming.
Programming language :- Python
Procedural Programming
A list of instructions telling a computer, step-by-step, what to do, usually having a linear order of execution from the first statement to the second and so forth with occasional loops and branches.
A procedural program is composed of one or more units or modules--either user coded or provided in a code library; each module is composed of one or more procedures, also called a function, routine, subroutine, or method, depending on programming language.
Programming language :- C

I started my job on the 15 of February 2006.Last four year i was work on the Tradecard project.It's supply chain management system.In my latter part of the job,Sabre came to and join venture with TradeCard Inc and formed a new organizaion called TradeCard Services Pvt Ltd.
There fore In 2008 Dec I have to resign Sabre and rejoin to TradeCard Services Pvt Ltd.
with my first job i have learn lot of things.With the j2EE technologies I have put my foundation.That is in 2007 May I have pass the Sun Certified Java Programmer Exam.during these period I have work with jsp,servlet,and hibrenate technologies.Also I was fortunate to work with MVC architecture.

Flow Chart Diagram
A flow chart is a graphical or symbolic representation of a process. Each step in the process is represented by a different symbol and contains a short description of the process step. The flow chart symbols are linked together with arrows showing the process flow direction.
Your can refer the above table for the Flow chart Diagram's Symbol.
