what is the difference between div and span tags

DIV TAG:

Following are the characteristics:

As the name indicates, the div tag defines a ‘division’ in a web page.
div is a block-element; its default display value is “block”.
div tag is commonly used while creating Css based layouts in html.
by default, a line-break is placed before and after this element.

SPAN TAG:

Following are the characteristics:

span tag makes no visual difference in the page, unless customised with style attribute.
span is an in-line element.
span is commonly used to stylize texts. The in-line feature makes it easy to use custom styles without changing the layout.
No line-breaks by default, but this can be achieved if we change its in-line nature by specifying in the style attribute to ‘display:block;’

Scalable Vector Graphics.

SVG stands for Scalable Vector Graphics.

SVG defines vector-based graphics in XML format.

Create a Simple Java Web Application Using Servlet, JSP and JDBC

Brower web app servlet

request >----------------------------------- insert,update,

response<----------------------------------- delete,select.......

..query

| forward

jsp page show

Frist You create a table in oracle ,mysql,Sql sver

create table USER_ACCOUNT

(

USER_NAME VARCHAR2(30) not null primary key,

GENDER    VARCHAR2(1) not null,

PASSWORD  VARCHAR2(30) not null

);

create table PRODUCT

(

CODE  VARCHAR2(20) not null primary key,



NAME  VARCHAR2(128) not null,

PRICE FLOAT not null

) ;
















insert into user_account (USER_NAME, GENDER, PASSWORD)





values ('prabal', 'M', 'niit@123');






insert into user_account (USER_NAME, GENDER, PASSWORD)

values ('akash', 'M', 'niit@123');










insert into user_account (USER_NAME, GENDER, PASSWORD)

insert into product (CODE, NAME, PRICE)

values ('P001', 'Java Core', 100);



insert into product (CODE, NAME, PRICE)

values ('P002', 'C program', 90);







insert into product (CODE, NAME, PRICE)





values ('P003', 'Devops', 9000);







Then Go to Eclipse and open Dynamic project

And add index.html









 then write a index.html


<html>

  <head>

     <meta charset="UTF-8">

     <title>Simple Web Application</title>

  </head>

  

  <body>

some-jdbc-drivers.zip (MySQL + SQL Server + Oracle)



)into the WEB-INF/lib:

       this.code = code;

   }



   public String getName() {

       return name;

   }



   public void setName(String name) {

       this.name = name;

   }



   public float getPrice() {

       return price;

   }



   public void setPrice(float price) {

       this.price = price;

   }



}





then create a package For connection




and add class for oracle





import java.sql.Connection;

import java.sql.DriverManager;

import java.sql.SQLException;



public class OracleConnUtils {



  public static Connection getOracleConnection()

          throws ClassNotFoundException, SQLException {

      

      // Note: Change the connection parameters accordingly.

      String hostName = "localhost";

      String sid = "db11g";

      String userName = "system";

      String password = "oracle";



      return getOracleConnection(hostName, sid, userName, password);

  }



  public static Connection getOracleConnection(String hostName, String sid,

          String userName, String password) throws ClassNotFoundException,

          SQLException {



            

      Class.forName("oracle.jdbc.driver.OracleDriver");





      // URL Connection for Oracle

      // Example: jdbc:oracle:thin:@localhost:1521:db11g

      String connectionURL = "jdbc:oracle:thin:@" + hostName + ":1521:" + sid;



      Connection conn = DriverManager.getConnection(connectionURL, userName,

              password);

      return conn;

  }

}





Add a class ConnectionUtils 






import java.sql.Connection;

import java.sql.SQLException;



public class ConnectionUtils {



   public static Connection getConnection()

             throws ClassNotFoundException, SQLException {

      

       // Here I using Oracle Database.

       return OracleConnUtils.getOracleConnection();

     }

    

   public static void closeQuietly(Connection conn) {

       try {

           conn.close();

       } catch (Exception e) {

       }

   }



   public static void rollbackQuietly(Connection conn) {

       try {

           conn.rollback();

       } catch (Exception e) {

       }

   }
