Hi,
I am trying to run my first simple bean and I am using the following
code

**** BeanTest.jsp ****
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

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

<body>

<jsp:useBean id="test" class="Beans.SimpleBean"/>
<jsp:setProperty name="test" property="message" value="aw ras"/>

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

</body>
</html>

**** SimpleBean.java ****
package Beans;

public class SimpleBean
{
private String message = "No message specified";

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

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

I have placed the two files in the same location, compiled the Simple
Bean, which generated the folder Beans with SimpleBean.class in it.
Then I opened my browser and tried to run the BeanTest.jsp.... and
gave me the following errors.

HTTP Status 500 -

Where did U put the classes?

they should go under /yourwebapp/WEB-INF/classes ...

or /yourwebapp/WEB-INF/lib (if on jar)
