Master,

Disciple, ;-)

Can you show us the light? As I posted before I never used beans. But
after seeing some comments here. I feel as something is missing to me. I
want to do Java Beans. I use jEdit to work. :-)

I suspect that you might be confusing plain Java Beans and Enterprise Java Beans (EJBs).

I'm talking about the former here. This is a bean:

public class Customer {
private Long id;
private String name;
private Address address;

public Long getId() { return id; }
public void setId(Long id) { this.id = id; }
public String getName() { return name; }
public void setName(String name) { this.name = name; }
public Address getAddress() { return address; }
public void setAddress(Address address) { this.address = address; }
}

If you have this kind of object, you can:

- easily persist it via Hibernate (or any other O/R mapping tool) to one or more relational tables

- easily access its attributes from the flow:

var cust = new Customer();
cust.name = 'Acme Inc.';
log.debug("Customer name = " + cust.name);

- easily bind it to a form:

var form = new Form(formId, cust);

- easily refer to its attributes, using XPath syntax, in the form descriptor:

<xf:textbox ref="/name">

- easily retrieve its attributes in the view (XSP) using XPath syntax:

<jpath:value-of select="cust/name"/>

If I were lazier, I'd  even use XDoclet to generate the Hibernate
mapping files from javadoc comments in the source.

This is interesting too. How it works?

Using Hibernate, you have to declare how your objects map to relational tables in a "mapping document" (XML file). With XDoclet, you get to automatically generate your mapping files from Javadoc-like comments in the source. I haven't uesd it yet, so I cannot tell you more about this.
