Abstract

For browsing entity beans in a client-server environment using the Enterprise Java Beans (EJB) architecture a generic servlet is provided for receiving a service requests from a Web browser and for initiating an access to an entity bean directory to identify an entity bean home according to a bean name contained in the request. The identified entity bean home is asked for a specific entity bean instance using key information passed with the service request. The identified bean instance is introspected by using getBeanInfo( ) methods of the Java Bean Introspector. The information achieved by the introspection is used for retrieving entity bean properties from an EJB persistency store. On the basis of the retrieved information the generic servlet generates a response which provides a representation of the retrieved information. The generic servlet allows to avoid the development of customized servlets which comprise specific code for the browsing and editing of different entity bean classes.
