Drag and Drop using jQuery JavaScript in HTML

Using jQuery you can create simple Drag & Drop features easily and manage them well. jQuery UI provides with a vast suite of APIs that can create a UI with Drag Drop functionality.
Steps :-

1. Create a HTML file which includes css, jquery & javascript libraries .

<!DOCTYPE html>
<html>
<head>
<meta charset=utf-8>
<title>Drag and drop</title>

<LINK REL=StyleSheet HREF="css/makecodeeasy.css" TYPE="text/css">
<link rel="stylesheet"
    href="http://code.jquery.com/ui/1.10.3/themes/smoothness/jquery-ui.css">
<script src="http://code.jquery.com/jquery-1.9.1.js"></script>
<script src="http://code.jquery.com/ui/1.10.3/jquery-ui.js"></script>

</head>
<body>

    <div>
        <fieldset id="shop" class="draggableContainer">
            <legend>Draggable component</legend>
            <img class="component" id="1" src="image/1.jpg"> 
            <img class="component" id="2" src="image/2.jpg"> 
            <img class="component" id="3" src="image/3.jpg"> 
            <img class="component" id="4" src="image/4.jpg">
        </fieldset>
    </div>

    <div>
        <fieldset>
            <legend>dropZone</legend>
            <div class="dropZone" id="dropZone"></div>
        </fieldset>
    </div>

    <script src="js/makecodeeasy.js"></script>

</body>
</html>

2. Create Javascript file (makecodeeasy.js)

var dropArea = document.querySelector('#dropZone');

var conponents = document.querySelectorAll('.component');
for ( var i = 0; i < conponents.length; i++) {
    conponents[i].setAttribute('draggable', 'true');
    conponents[i].addEventListener('dragstart', function(evnt) {
        evnt.dataTransfer.effectAllowed = 'copy';
        evnt.dataTransfer.setData('text', this.id);
        return false;
    }, false);
}

dropArea.addEventListener('dragover', function(evnt) {
    if (evnt.preventDefault)
        evnt.preventDefault();
    evnt.dataTransfer.dropEffect = 'copy';
    return false;
}, false);


dropArea.addEventListener('drop', function(evnt) {
    if (evnt.stopPropagation)
        evnt.stopPropagation();
    var id = evnt.dataTransfer.getData('text');
    var theitem = document.getElementById(id);

    if (theitem == null) {
        evnt.preventDefault();
        return;
    }
    var y = document.createElement('img');
    y.src = theitem.src;
    dropArea.appendChild(y);
    evnt.preventDefault(); // for Firefox
    return false;
}, false);

3. Create css file (makecodeeasy.css) 

body {
    padding: 40px;
}

.draggableContainer {
    border-radius: 6px;
}


.component {
    border: 3px solid white;
}

.component:hover {
    border: 3px solid red;
    cursor: move;
}

#dropArea {
    position: relative;
    height: 200px;
    width: 100%;
    float: left;
    border: 1px dotted #999;
}


.dropZone {
    width:100%;
    height:100px
}

4.  Demo

Virtual wall concept to protect pedestrians

 

Pedestrian/motor vehicle crashes are a serious problem throughout the world and the India has a particular problem with pedestrian deaths and injuries.
Almost two-thirds of the 1.2 million people killed annually in road traffic crashes worldwide are pedestrians.

The sequence of events in a car-pedestrian accident

Traffic accidents are among the major causes of death in India. Every year increased the pedestrian accidents at pedestrian crossing zone. And I thought that crossing zone is sharing space between pedestrian and driver. But drivers are never care which pedestrian’ safety in the real world. Even drivers are sometimes switching to pedestrian. And nowadays, urban sites got the problem that disturbance of traffic signal. We are surrounded such a crazy commercials and crowd environment near the road space.


That’s a one of reason that many drivers losing attention and difficulty of awareness into traffic signal. And, I’d like to make wall up on the car’ stop line at the moment. Virtual Wall, It’s really effective in driver awareness. Because Virtual Wall can get bigger image and better look.

the inventor of this concept is  Hanyoung  Lee, got  awarded for this  creation work. this can be implemented in all zones for a better safety of pedestrians the concept work like this : at the junctions some two poles are fixed and when the pedestrians crossing the road these poles produces some rays which are visible to naked eye looks like a wall infront of them so this will gives more safety for the pedestrians.

Two Datasource in Spring/Hiberate

We can create two datasource in a single spring/hibernate application.

There are following steps required to implement this:-

Create JNDI Datasource while using Tomcat :- 

1. Resource entry in server.xml under <GlobalNamingResources> for both datasources
   You can find server.xml in following path in Tomcat folder :-
    c://Tomcat/conf/server.xml

<globalnamingresources>
    <resource name="jdbc/first"  driverclassname="com.microsoft.sqlserver.jdbc.SQLServerDriver" maxwait="5000" password="makecodeeasy" type="javax.sql.DataSource" url="jdbc:sqlserver://localhost:1433;DatabaseName=DataTest" username="makecodeeasy" validationquery="select 1">
    </resource>

 <resource name="jdbc/second"  driverclassname="com.microsoft.sqlserver.jdbc.SQLServerDriver" maxwait="5000" password="123" type="javax.sql.DataSource" url="jdbc:sqlserver://192.182.21.66:1433;DatabaseName=Second" username="sa" validationquery="select 1">
    </resource>
 </globalnamingresources>

Note :- Database used here in MS Sql server 2008. You can use any database. You need to change driverClassname, url, username and password according to  database.
2. Do the entry in web.xml for both resources
   You can find web.xml in WEB-INF folder of your application

<resource-ref>
  <description>DB Connection Pooling</description> 
  <res-ref-name>java:comp/env/jdbc/first</res-ref-name> 
  <res-type>javax.sql.DataSource</res-type> 
  <res-auth>Container</res-auth> 
  <res-sharing-scope>Shareable</res-sharing-scope> 
</resource-ref>


<resource-ref>
  <description>DB Connection Pooling</description> 
  <res-ref-name>java:comp/env/jdbc/second</res-ref-name> 
  <res-type>javax.sql.DataSource</res-type> 
  <res-auth>Container</res-auth> 
  <res-sharing-scope>Shareable</res-sharing-scope> 
</resource-ref>

3. Use datasource in applicationContext or spring context file

<bean id="firstDataSource" class="org.springframework.jndi.JndiObjectFactoryBean">
  <property name="jndiName" value="java:comp/env/jdbc/first" /> 
  <property name="resourceRef" value="true" /> 
</bean>

<bean id="secondDataSource" class="org.springframework.jndi.JndiObjectFactoryBean">
  <property name="jndiName" value="java:comp/env/jdbc/second" /> 
  <property name="resourceRef" value="true" /> 
</bean> 

4. Create two session factory for using two datasource.
   

   <bean id="firstSessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean" p:dataSource-ref="firstDataSource" p:configLocation="${hib.config}" p:packagesToScan="com.org.xyz.domain">
   </bean>

   <bean id="secondSessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean" p:dataSource-ref="secondDataSource" p:configLocation="${hib.config}" p:packagesToScan="com.org.abc.domain">
   </bean>

   
   
5. Now these session factories can be used in Hibernate application.
   

JNDI Datasource in spring

There are two sources of database connections - either a  DataSource or a  DriverManager.

JNDI
The Java Naming and Directory Interface (JNDI) is part of the Java platform, providing applications based on Java technology with a unified interface to multiple naming and directory services. You can build powerful and portable directory-enabled applications using this industry standard.

Create JNDI Datasource while using Tomcat :- 

1. Resource entry in server.xml under <GlobalNamingResources>
   You can find server.xml in following path in Tomcat folder :-
    c://Tomcat/conf/server.xml

<globalnamingresources>
    <resource name="jdbc/test"  driverclassname="com.microsoft.sqlserver.jdbc.SQLServerDriver" maxwait="5000" password="makecodeeasy" type="javax.sql.DataSource" url="jdbc:sqlserver://localhost:1433;DatabaseName=DataTest" username="makecodeeasy" validationquery="select 1">
    </resource>
</globalnamingresources>

Note :- Database used here in MS Sql server 2008. You can use any database. You need to change driverClassname, url, username and password according to  database.
2. Do the entry in web.xml
   You can find web.xml in WEB-INF folder of your application

<resource-ref>
  <description>DB Connection Pooling</description> 
  <res-ref-name>java:comp/env/jdbc/test</res-ref-name> 
  <res-type>javax.sql.DataSource</res-type> 
  <res-auth>Container</res-auth> 
  <res-sharing-scope>Shareable</res-sharing-scope> 
</resource-ref>

3. Use datasource in applicationContext or spring context file

<bean id="dataSource" class="org.springframework.jndi.JndiObjectFactoryBean">
  <property name="jndiName" value="java:comp/env/jdbc/test" /> 
  <property name="resourceRef" value="true" /> 
</bean>

4. Your Datasource is ready to use. It can also be used in hibernate.
