i am new in jsp.i am trying to use useBean in jsp to run a class named hi.
i am using apache tomcat as a web server.i placed the file hi.class as well as the file that i named it date.jsp which uses the hi class in the folder webapps
the code of date.jsp is:

JSP Syntax (Toggle Plain Text)

<%@ page import="java.util.*" %><%@ page import="java.lang.*" %><HTML><BODY><jsp:useBean id=“my” scope="request" class=“hi”><jsp:getProperty name="my" property="*"/></jsp:useBean><%my.print()%;></BODY></HTML><%@ page import="java.util.*" %>
<%@ page import="java.lang.*" %>
<HTML>
<BODY>
<jsp:useBean id=“my” scope="request" class=“hi”>
<jsp:getProperty name="my" property="*"/>
</jsp:useBean>
<%my.print()%;>
</BODY>
</HTML>

the code of hi.class is:

import java.lang.*;import java.util.*;public class hi{public static int print(){System.out.println("hi");return 1;}public static void main(String args[]){System.out.println(print());}}import java.lang.*;
import java.util.*;
public class hi{
public static int print()
{System.out.println("hi");
return 1;
}
public static void main(String args[])
{System.out.println(print());
}
}

i am getting this error when i run date.jsp in web browser:

Take a look at this:

<%my.print()%;>

The quote is in the wrong place. The idea is that you write java code inside the <% .. %>

Inside a JSP page:

<%
int a = 0;
a = my.print();
%>

<!-- This is not java. It is displayed at the page: -->
Result: <%= a %>

<!-- OR -->
Result: <%= my.print() %>
