Tomcat 3.2.3 on Win2K - Attribute class has no value - Javabean problem
Ariel Shmorak
I have a web app called "myapp" under the "webapps" dir (I set it up
in server.xml). Under this, I have a "WEB-INF/classes/mybeans" Dir.
This is where my javabean, lineBean.class, resides.
The jsp page (test.jsp) resides in the "myapp" folder and looks like
this:
-------------------
<%@ page import="mybeans.*" %>
<html>
<head>
<title>Untitled Document</title>
<meta http-equiv="Content-Type" content="text/html;
charset=iso-8859-1">
</head>
<body bgcolor="#FFFFFF" text="#000000">
<jsp:useBean class"mybeans.lineBean" id="mybean" scope"page" />
<%= mybean.stars(20) %>
</body>
</html>
--------------------
lineBean.java looks like:
---------------------
package mybeans;
public class lineBean
{
public String stars(int x)
{
String text = "<br>";
for (int i = 0; i < x; i++)
text = text + "*";
return text + "<br>";
}
}
--------------------------
How does Tomcat know where I am storing my class files? Is the WEB-INF
correct?
My error I am getting is:
---------------------
Location: /myapp/test.jsp
Internal Servlet Error:

Any help would be much appreciated.

You forgot the "=" between class and mybeans.lineBean in your JSP page. You
also forgot one between scope and page. The line should read:
<jsp:useBean class="mybeans.lineBean" id="mybean" scope="page" />
I tried it on my system and everything works fine once those errors are
corrected. Hope this helps!!
