JSP Java Code to Post Data to SQL database using Tomcat Server

Posted by TechBlogger on 7:45 PM

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 following is the code for form . Just name it addstud.jsp . After submit button is pressed then the details are forwarded to addstudinfo.jsp which connects to the database and enters the data into mysql database.

addstud.jsp

<%@page session="true"import="java.io.*"%>
<html>
<body bgcolor="#d0d0d0">
<br></br>
<br></br>
<br></br>
<h2><center>enter stuent details</center></h2>

</td></tr>
<tr><td>
<b>id:</b>
<input type="text"name="id"/>
<br/>
<br/>
</td></tr>
<tr><td>
<b>age:</b>
<input type="text"name="age"/>
<br/>
<br/>
</td></tr>
<tr><td>
<b>branch:</b>
<input type="text"name="branch"/>
<br/>
<br/>
</td></tr>
</table>
<center>
<input type="submit"value="submit"/>
<input type="reset"value="reset"/>
<input type="button"value="delete"/>

</body>
</html>

Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
con=DriverManager.getConnection("jdbc:odbc:student1","username","password");
try
{
String s1=request.getParameter("name");
String s2=request.getParameter("id");
String s3=request.getParameter("age");
String s4=request.getParameter("branch");
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
con=DriverManager.getConnection("jdbc:odbc:student1","sa","sa");
stmt=con.createStatement(); //opening a connection
stmt.executeUpdate("insert into studentinfo(name1,id1,age,branch)values('"+s1+"','"+s2+"','"+s3+"','"+s4+"')");
%>
//inserting into database

data enterd successfully...........
<%
stmt.close();//close conncetion
stmt=null;
}
finally
{
if(con!=null)
{
con.close();
}
}

Keep both the files in the tomcat server and then run it from the browser on port 8000 (or as configured on the system)

Rolling ball Computer Animation Program using C++ VB 6.0

Posted by TechBlogger on 10:26 AM

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));
		pDC->Ellipse(ball[0].x++,ball[0].y,ball[1].x++,ball[1].y);
		pDC->MoveTo(10,150);
	pDC->LineTo(600,150);

Implementing Missionaries and cannibals problem in C++ Program code

Posted by TechBlogger on 9:47 AM

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.)

Implementing Symmetric Key Encryption technique Using C++ program

Posted by TechBlogger on 11:47 PM

INTRODUCTION:

Symmetric Key encryption technique uses only one key to encrypt/decrypt a message. This program is implemented in C++ .

PROGRAM:

#include<iostream.h>
#include<stdio.h>
#include<string.h>
#include<stdlib.h>
int main()
{ 
 int key1,key2;
 char s,wish;
 int choice;
 printf("\nExpt No.3 \tSYMMETRIC ENCRYPTION AND DECRYPTION\t18/02/2013");
 do {
 cout<<"\n1:Sender side\n2:Receiver side\n3:exit(0)";
 cout<<"\nEnter your choice:";
 cin>>choice;
 
 printf("\nAt Sender side:");
 printf("\nEnter the key:");
 scanf("%d",&key1);

 printf("\nAt Receiver side:");
 printf("\nEnter the key:");
 scanf("%d",&key2);
 printf("\nEnter the message:");
  s=getchar();
 
 if(key1==key2)
 {
  printf("\nKeys Match..you can proceed communication");

 }
 else
 {
  printf("\nKeys do not match...connection lost.....");
  exit(0);
 }
 switch(choice)
 {
 case 1:
 

  //  printf("\nEncrypted text is: ");
    while(s!='\n')
    {
     if(s==' ')
      putchar(s);
     else
     {
      putchar(s+key1);
     }
     s=getchar();
    }
    putchar(s);
    break;
    case 2:
     
     while(s!='\n')
     {
      if(s==' ')
       putchar(s);
      else{
       putchar(s-key2);
      }
      s=getchar();
     }
     putchar(s);
     break;
    default:
     exit(0);
 }
    printf("\nDo you want to continue communnication:?(y or Y)");
    scanf("%c",&wish);
    } while(wish=='y'||wish=='Y');
  return 0;
}
