But, the same case arrises here, as in defining number of beans. How will be the number of beans be pre-defined??

There's some stuff over on jguru that might be helpful. Also, I'm trying to write documentation for the struts user's guide for this, so I'd appreciate your comments on how (un)clear the following is (apologies for the formatting, my mail client sucks): <section name="4.2.3 Map-backed ActionForms" href="map_action_form_classes"> <p>The DynaActionForm classes offer the ability to create ActionForm beans at initialization time, based on a list of properties enumerated in the struts configuration file. However, many HTML forms are generated dynamically at request-time. Their ActionForm beans' properties are not all known ahead of time, so we need a new approach.</p> <p>Struts allows you to make one (or more) of your ActionForm's properties ' values a Map instead of a traditional atomic object. You can then store your form's dynamic fields' data in that Map. Here is an example of a map-backed ActionForm class:</p> <pre> <![CDATA[ public FooForm extends ActionForm { private final Map values = new HashMap(); public void setValue(String key, Object value) { values.put(key, value); } public Object getValue(String key) { return values.get(key); } } ]]> </pre> <p>In its corresponding JSP page, you can access objects stored in the values map using a special notation: <i>mapname(keyname)</i>. The parantheses in the bean property name serve to indicate that the bean property named <i>mapname</i> should be a Map, and that struts should look at the value stored with the key <i>keyname</i> in that Map to find the "real" property for <i>mapname(keyname)</i>.</p> <p>Here is a simple example:</p> <pre> <![CDATA[ <html:text property="value(foo)"/> ]]> </pre> <p>This will call the getValue() method on FooForm with a key value of "foo" to find the property value. To create a form with dynamic field names, you might do something like this:</p> <pre> <![CDATA[ <% for (int i=0; i<10; i++) { String name = "value(foo-" + i + ")"; <html:text property="<%=name%>"/><br/> %> ]]> </pre> </section> Hope it helps, thanks in advance for any comments. - donald -- To unsubscribe, e-mail: <mailto:[EMAIL PROTECTED]> For additional commands, e-mail: <mailto:[EMAIL PROTECTED]> -- To unsubscribe, e-mail: <mailto:[EMAIL PROTECTED]> For additional commands, e-mail: <mailto:[EMAIL PROTECTED]> -- To unsubscribe, e-mail: <mailto:[EMAIL PROTECTED]> For additional commands, e-mail: <mailto:[EMAIL PROTECTED]>
