OpenBooks do not ask you to register or remember one more password.
|

You enter a name so that OpenBooks can refer you by name.

|
OpenBooks is a sample (and perhaps simple) web application to demonstrate
|
|
some of the new features of JPA 2.0 API. OpenBooks performs basic operations
|
|
such as <br>
|
|
<OL>
|
|
<LI>Search for Books using a form-base query</LI>
|
|
<LI>Place Purchase Orders for a set of Books</LI>
|
|
<LI>Show the status of pending Purchase Orders </LI>
|
|
<LI>Change the status of pending orders </LI>
|
|
</OL>
|
|
|
|
Each of these actions invokes a service that queries or transacts against a database.
|
|
This database interaction takes place via Java Persistence API (JPA).
|
|
OpenBooks is designed to work with <em>any</em> JPA 2.0 compliant provider.
|
|
Currently OpenBooks is deployed with <A HREF="http://openjpa.apache.org" target="_blank">
|
|
OpenJPA 2.0</A> as its JPA provider.
