1. Database settings and Insetion of data into SQL database.
2. Searching information from Database
3. Deleting informstion from database

Unlike JSP and PHP Servlet is also server side scripting language. Servlet is Java based, Here this post we are going to illustrate how to add, delete , update and Search data from a form interacting with SQL database.
For consideration we will need tomcat server installed running on the system by default at port 8080 and sql database running on the system.
STEP 1:
Create database in Microsoft sql Query analyser .
Create table with 4 fields viz StudentName , ID , Age and Branch.
->Keep ID as INT and set it as primary key
->keep StudentName as VARCHAR(100)
->keep age as INTEGER
->Keep Branch as VARCHAR(100)
STEP 2 :

JSP is widely used Java based server side scripting language . Here in this tutorial I am going to give you code which will post data from a html form. before you run through code ensure that the tomcat server is installed or you can download it directly from the official website also download and install Microsoft server 2000.Go to the database console and
1.Create database named "student1".
2.Create table with four fields NAME,ID,AGE and BRANCH , keep ID as primary key.
First we began with creating a html form. For consideration here we are going to create a form for entering student details such as NAME,ID,AGE and BRANCH....

The Animation program is Rolling Ball over a horizontal line . The ball start rolling at the start of the line and moves till the end of line length.The program is implemented using C++ MS Visual studio , MFC application.
PROGRAM:
void CAnimation1View::OnDraw(CDC* pDC)
{
CAnimation1Doc* pDoc = GetDocument();
ASSERT_VALID(pDoc);
// TODO: add draw code for native data here
POINT ball[2]={25,150,75,100};
pDC->Ellipse(ball[0].x,ball[0].y,ball[1].x,ball[1].y);
for(int i=0;i<600;i++)
{
pDC->FloodFill(50,50,RGB(100,100,100));

Basic Computer Animation Program using MS Visual Studio 6.0 with MFC application.Here in this program we make use of flood fill concept . The function is very simple indicating just coordinates which has to be displayed on the screen.
PROGRAM:
void CBouncingballView::OnDraw(CDC* pDC)
{
CBouncingballDoc* pDoc = GetDocument();
ASSERT_VALID(pDoc);
// TODO: add draw code for native data here
POINT ball[2]={25,150,75,100};
pDC->Ellipse(ball[0].x,ball[0].y,ball[1].x,ball[1].y);
for(int k=0;k<600;k++)
{
pDC->FloodFill(50,50,RGB(100,100,100));
pDC->MoveTo(10,150);
pDC->LineTo(600,150);

INTRODUCTION:
In the missionaries and cannibals problem(AI), three missionaries and three cannibals must cross a river using a boat which can carry at most two people, under the constraint that, for both banks, if there are missionaries present on the bank, they cannot be outnumbered by cannibals (if they were, the cannibals would eat the missionaries.) The boat cannot cross the river by itself with no people on board.The Program is implemented using C++ Programming language.
PROGRAM:
#include<iostream>
#include<list>
#include<stack>
using namespace std;
struct StateSTR
{
int Mlhs; //nr missionaries on LHS of river
int Clhs; //nr cannibals on LHS of river
