bean class code embended in JSP page wont work

i am using Sun Java System Application Server.

i found that my bean class code that embended in JSP page wont work,
--------------------------------------------------------------------------
<HTML>
<jsp:declaration>
// this is a local "helper" bean for processing the HTML form
static public class localBean
{
private String value;
public String getValue() { return value;}
public void setValue(String s) { value = s; }
}
</jsp:declaration>
<jsp:useBean id="localBean" scope="application" class="localBean" >
<%-- Every time we create the bean, initialize the string --%>
<jsp:setProperty name="localBean" property="value" value="World" />
</jsp:useBean>
<%-- Whatever HTTP parameters we have,
try to set an analogous bean property --%>
<jsp:setProperty name="localBean" property="*" />
<HEAD><TITLE>HelloWorld w/ JavaBean</TITLE></HEAD>
<BODY>
<CENTER>
<P><H1>Hello
<jsp:getProperty name='localBean' property='value'/></H1></P>
<FORM method=post>
Enter a name to be greeted:
<INPUT TYPE="text" SIZE="32" NAME="value"
VALUE="<jsp:getProperty name='localBean' property='value'/>">
<BR>
<INPUT TYPE="submit" VALUE="Submit">
</FORM>
</CENTER>
</BODY>
</HTML>

i need to explicitly create a C:\Learning\JSP\WEB-INF\classes folder, extract out the embended bean code from JSP page, compile it to class file and put it in the previous folder that created explicitly. then only it will work.

may i know how can i keep continue to make the bean class code embended in JSP page work without explicitly create a class file?

thank you.

So, you're saying if you extract out the localbean declaration and compile to localbean.class it works?
The problem is that your class="localbean" attribute assumes your localbean is not defined in a package. However, when your JSP gets compiled it is put into a package as thought it had "package jsp_servlet.subdir.subdir.subdir;" - depending on the path to your JSP.

I affirm it. I should have been more clearly but that's why I said no.
