Hello, So I can now make objects from XML, and use them as properties to beans I'm constructing as in this example:
<blueprint xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0"; xmlns:st="http://pizzaonline.demo.org/xmlns/menus-0.2"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";> <bean class="org.demo.pizzaonline.api.OrderInterface"> <property name="menuChoices"> <menu xmlns="http://pizzaonline.demo.org/xmlns/menus-0.2"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";> <meals> <meal name="Pizza Tonno" description="Tomato basis with tuna and cheese" price="9.5"/> <meal name="Pizza Quatro Fromagi" description="Four cheeses" price="8.5"/> </meals> </menu> </property> </bean> </blueprint> But is there a possibility to make the "menu" object a bean directly? I'd like to make the "<menu>" a service, that can be referenced to by other beans. But if I put the <menu> directly in a <service> or <bean> tag, the XML parsing fails. In the example given aboven, it seems I can build a wrapper around the objects build from XBean, but I wonder wether it's possible to do without the wrapper.
