Hi ,
Here is the example program that uses bean.
<html>
<head>
<title>greetings</title>
</head>
<body>
<jsp:useBean id="mydata" scope="application" class="data.empdata" />
<b>Data</b><p>
<%! String name=""; %>
<%! int id=0; %>
<% name = request.getParameter("name");
id = Integer.parseInt(request.getParameter("id"));
%>
<% mydata.setdata(id,name); %>
<p><a href = "emphome.htm"> HOME </a></p>
</body>
</html>
You have to use jsp:useBean directive in order to work with beans.
in the above example empdata is a bean that is loaded in data directory.
you can call bean functions using its id. see in above example
mydata.setdata()

Subject: JSP population using bean
Hello All,
I am having difficulties with populating a bean referenced within a JSP.
Basically I am trying to set a property of a bean from the input of a simple
HTML form. The following comes from 'hellobean.jsp'
<%@ import = "HelloBean" %>
<BEAN NAME="hello" TYPE="HelloBean"
INTROSPECT="yes" CREATE="yes" SCOPE="request">
</BEAN>
<HTML>
<HEAD><TITLE>Hello</TITLE></HEAD>
<BODY>
<H1>
Hello, <%= hello.getName() %>
</H1>
</BODY>
</HTML>
Here is the source code for the bean;
public class HelloBean {
private String name = "World";
public void setName(String name) {
this.name = name;
}
public String getName() {
return name;
}
}
This JSP page comes from an example from a book and conforms to 0.9x
release. I am using JavaWebServer 2.0, JSWDK 1.0.1 ( which is based on
the 1.0 release of JSP I believe ) and JDK 1.2.2. I can't find any reference
to
the <bean>...</bean> tags and I am wondering if they are deprecated from
an earlier version of JSP.
Whenever I enter the URL "localhost:8080/hellobean?name=fred" the server
cannot successfully create the servlet based on the JSP file. I have placed
the bean source file in the 'classes' directory of the webserver.
Any ideas? Example JSP would be much appreciated.
Thanks and regards,
AT
