The directive <jsp:usebean> is misleading as these are not true Java beans, they
can be regular Java class objects. The JavaBean structure only needs to be
applied when using the set/get property directive.
The following is valid where MyObject is NOT a Java Bean.
<jsp:useBean id="MyObject" class="com.MyClass" scope="session"/>
<input type="text" name="username" value="<%=MyObject.getUsername()%>">
cheers,

Subject: Why use Java Beans?
I'm finding it difficult to fully grasp the benefit of using Java beans with
a MVC JSP/servlet architecture. I am more keen to use JSP taglibs and <%=
expressions %> to represent data in my pages. <jsp:usebean> was a mechanism
that was present in the JSP spec before taglibs were introduced in JSP 1.1.
Java Beans may have more necessity within servlets that being called
directly from within a JSP page.
Does anyone have any arguments for the usage of JavaBeans (as opposed to
regular objects in a servlet) in a web-based project?
Thanks,
Philip Weaver
