Entity bean data survives crashes.

An entity bean represents non-persistent data.

It creates its own JAR file during deployment.

You get authentication code without having to write any.

When you want to be certain your application data persists between program invocations, even in the event of a crash.

If you need to initiate a database transaction.

To process transient data that can be re-created in the event of a crash.

To keep people who do not know how to program from accidentally changing important logic code

To make the user interface more interesting.

To simplify application deployment.

To prevent malicious programs from gaining access to sensitive information on your database server.

To make the application much easier to update, maintain, and manage.

XML imposes important limitations on the receiving program or tool.

The receiving program or tool can use the XML tagging information to determine how to best handle the incoming data.

XML tags offer an extra level of security

XML tags specify to the receiving program or tool exactly how to format and display the data.

The thin client.

Deployment descriptors.

The JAR file.

The bean's container

When you implement entity or session bean methods to use SQL commands you provide.

When the bean's container handles data storage and retrieval.

When the J2EE server is never shut down

When changes to database data are lost during a crash.

By thin clients.

By calls to the database.

By the J2EE server.

By the bean's container.

It's always going to be less expensive and more secure than local computing.

You can access your data from any computer in the world as long as you have an Internet connection.

Only a few small companies are investing in the technology, making it a risky venture.
