Java beans and JSP Example Atoms
JavaBeans Example: Atoms.java, Atoms.jsp, Atoms.class, Atoms.html

 1. The steps 

1. Create new directory : newBeans under:
C:\Program Files\Apache Software Foundation\Tomcat 6.0\
webapps\examples\WEB-INF\classes\
directory. And then a new one under newBeans: 
newBeans\AtomBeans

2. Place the Java program Atoms in it :
C:\Program Files\Apache Software Foundation\Tomcat 6.0\
webapps\examples\WEB-INF\classes\newBeans\AtomBeans\Atoms.java
The Java program Atoms.java will have the following package:
package newBeans.AtomBeans; (subdirectories after \classes\)

3. Create a subdirectory (or subdirectories) under 
\webapps\ like this:
C:\Program Files\Apache Software Foundation\Tomcat 6.0\
webapps\examples\NewWork\BeansAtoms\
\examples\ already exist; NewWork\BeansAtoms\  is created. 

4. Place the JSP program Atoms.jsp in it as follows:
C:\Program Files\Apache Software Foundation\Tomcat 6.0\
webapps\examples\NewWork\BeansAtoms\Atoms.jsp

5. Rum the program Atoms.jsp by browsing:
http://localhost/examples/NewWork/BeansAtoms/Atoms.jsp



 2. The bean program Java:Atoms.java

package newBeans.AtomBeans;

public class Atoms implements java.io.Serializable {

private static final long serialVersionUID = 1L;

//Fields = properties
private String element = null;
private int charge = 0;
private int shell = 0;

// Constructor	
public Atoms() {}

// Methods: Setter
public void setelement(String element) {
this.element = element;
}

public void setcharge(int charge) {
this.charge = charge;
}

public void setshell(int shell) {
this.shell = shell;
}

// Method: Getter
public String getelement() {
return this.element;
}

public int getcharge() {
return this.charge;
}

public int getshell() {
return this.shell;
}

}


 3. Atoms.jsp 


<html>
<head>
<title> The atoms bean JSP Page</title>
</head>
<body>

<%@ page language="java" import="
newBeans.AtomBeans.Atoms"%> 
<%@ page contentType="text/html" %>


<%-- Create the JavaBean: of ID = Bohr --%>
<jsp:useBean id = "Bohr" scope="request"  class = 
"newBeans.AtomBeans.Atoms">
<jsp:setProperty name = "Bohr" property = 
"element" value = "Hydrogen" />
<jsp:setProperty name = "Bohr" property = 
"charge" value="1" />
<jsp:setProperty name = "Bohr" property = 
"shell" value="1" /> 
</jsp:useBean>

<p>
Retrieve the properties from JavaBean and display 
their values :<br>
The charge and the shell of the element 
<jsp:getProperty name="Bohr" property = "element"/> 
are respectively:
<jsp:getProperty name="Bohr" property = "charge"/> 
and 
<jsp:getProperty name="Bohr" property = "shell"/>. 
<br>

</p>
</body>
</html>


 4.The result 	

The result under: http://localhost/examples/NewWork/BeansAtoms/Atoms.jsp 
is:

Retrieve the properties from JavaBean and display their values :
The charge and the shell of the element Hydrogen are respectively: 1 and 1.
