Yes, exactly.
But, I still have a problem. Here is my detail.....
I'm using Tomcat3.2.1 on WinNT4, with JDK1.3.
Under this path: <<tomcat_home>>\webapps\examples\jsp\happy, I have this
file,
*************************************
<!-- A JSP to test -->
<jsp:useBean id='happy' scope='page' class='Test' type='TestIF' />
<html>
<head>
<title>Test Bean</title>
</head>
<B>The result is: </B> <jsp:getProperty name="happy" property="happy"/>
<B>Test database: </B> <jsp:getProperty name="happy" property="database"/>
</html>
********************************
My interface is this:
//package examples;
import java.sql.*;
public interface TestIF {
public String getDatabase();
}
**************************
My Test class just implements the getDatabase method along with another
getter for happy. Without doing this interface business, I could get this to
run by having the; package examples; line in my Test.java. And, having this
section in my JSP, class='examples.Test'
But, if I try to comment out the package declaration in my classes and go
with class='Test' type=..... in my JSP, it gives me this error:
Root cause:
java.lang.ClassNotFoundException: Unable to load class Test
I have a configuration problem somewhere. Any ideas?
I'm only worried about getting this simple interface example to work, then
I'll look at my design, coding style, etc....

Subject: AW: Interfaces with JSP's
Yes, this is possible.
<jsp:useBean id="anyName" class="org.alexmeyer.AnyClass"
type="org.alexmeyer.AnyInterface" />
You can imagine this like:
AnyClass anyClass = (AnyInterface)new AnyClass();
Is this that what you mean???
