Hi,
I am trying again the following code... some changes have beend done
from last.

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

<html>
<head>
<title>Reusing Java Beans</title>
</head>

<body>

<%@ page import="Beans.*" %>

..... the main change was here: class - type (I'm not sure what it is
but on the internet I found it like that)

<jsp:useBean id="Simple" scope="session" type="Beans.SimpleBean"/>
<jsp:setProperty name="Simple" property="message" value="aw ras"/>

Message:
<jsp:getProperty name="Simple" property="message"/>

</body>
</html>

package Beans;
import java.beans.*;

public class SimpleBean
{
private String message;

public SimpleBean()
{
} // end constructor

public String getMessage()
{
return (message);
} // end method getMessage

public void setMessage(String message)
{
this.message = message;
} // end method setMessage

} // end class SimpleBeans

The paths I am using are
for SimpleBean.java - \Tomcat
5.0\webapps\jsp-examples\WEB-INF\classes\cal\
for SimpleBean.class - \Tomcat
5.0\webapps\jsp-examples\WEB-INF\classes\cal\Beans\
for BeanTest.jsp - \Tomcat 5.0\webapps\jsp-examples\cal\

The error being reported now is the following

HTTP Status 500 -
