grammatic transaction control in Java SE applications that use Java Persistence. Declarative transaction demarcation, on the other hand, doesn t require extra coding; and by definition, it solves the problem of portability. Declarative transaction demarcation In your application, you declare (for example, with annotations on methods) when you wish to work inside a transaction. It s then the responsibility of the application deployer and the runtime environment to handle this concern. The standard container that provides declarative transaction services in Java is an EJB container, and the service is also called container-managed transactions (CMT). We ll again write EJB session beans to show how both Hibernate and Java Persistence can benefit from this service. Before you decide on a particular API, or for declarative transaction demarcation, let s explore these options step by step. First, we assume you re going to use native Hibernate in a plain Java SE application (a client/server web application, desktop application, or any two-tier system). After that, you ll refactor the code to run in a managed Java EE environment (and see how to avoid that refactoring in the first place). We also discuss Java Persistence along the way.

better scalability With server-side state management, each client that connects to the web server consumes memory on that server. If a website has hundreds (or thousands) of simultaneous users, the memory consumed by storing state management information can become a limiting factor. Pushing this burden to the clients removes that potential bottleneck and frees the server to use its resources to serve more requests. support for multiple web servers With client-side state management, you can distribute incoming requests across multiple web servers (or a web farm). In this scenario, each client provides all the information any web server needs to process a request. With server-side state management, if a client switches servers in the middle of the session, the new server does not necessarily have access to the client s state information (because it is stored on a different server). You can use multiple servers with server-side state management, but you need either intelligent load balancing (to always forward requests from a client to the same server) or centralized state management (where state is stored in a central database to which all web servers have access). better security Unless you digitally sign information stored on a client, users can change client-side state management information. Therefore, you should never use client-side state management to store confidential information such as passwords, access levels, or authentication status.
