This section discusses how to build an
|
|||
|
|
application using the DPL. The DPL is ideally
|
|||
|
|
suited for those applications that want a
|
|||
|
|
mechanism for storing and managing Java class
|
|||
|
|
objects in a JE database. Note that the DPL
|
|||
|
|
is best suited for applications that work with
|
|||
|
|
classes with a relatively static schema.
|
|||
|
|
</p>
|
|||
|
|
<p>
|
|||
|
|
The DPL requires Java 1.5.
|
|||
|
|
</p>
|
|||
|
|
<p>
|
|||
|
|
If you are porting an application
|
|||
|
|
from the Berkeley DB API, then you probably want
|
|||
|
|
to use the base API instead of the DPL. For
|
|||
|
|
information on using the base API, see
|
|||
|
|
