IV. Creating a Web Client
The web client is divided into two pages. First
is “form.jsp” where a request form is sent to
the client; second is “WebClient.jsp” which is
called from the “form.jsp” page.
The source code for the “form.jsp” is given
below.
<html>
<head>
<title>Library</title>
</head>
<body bgcolor=”pink”>
<h1>Library</h1>
<hr>
<form action=”WebClient.jsp”
method=”POST”>
<p>Enter the Title:
<input type=”text” name=”t1"
size=”25"></p>
<br>
<p>Enter Author name: |
|
<input type=”text” name=”aut” size=”25">
</p>
<br>
<p>Enter Price:
<input type=”text” name=”price” size=”25">
</p>
<br>
<p>
<input type=”submit” value=”Submit”>
<input type=”reset” value=”Reset”>
</p>
</form>
</body>
</html>
The following statements given below in “WebClient.jsp” are used for locating the
business interface, creating an enterprise bean
instance, and invoking a business method.
InitialContext ic = new InitialContext();
BookCatalogInterface bci =
(BookCatalogInterface) ic.lookup(“book/
BookCatalogBean/remote”);
The full source code for the WebClient.jsp is
given below.
<%@ page contentType=”text/html;
charset=UTF-8" %>
<%@ page import=”entity.library.*,
javax.naming.*, java.util.*”%>
<%!
private BookCatalogInterface bci = null;
String s1,s2,s3;
Collection list;
public void jspInit() {
try {
InitialContext ic = new
InitialContext();
bci = (BookCatalogInterface)
ic.lookup(“book/BookCatalogBean/remote”);
System.out.println(“Loaded Bank Bean”);
} catch (Exception ex) {
System.out.println(“Error:”+
ex.getMessage());
}
}
public void jspDestroy() {
bci = null;
}
