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
|
||
<a class="xref" href="baseapi.html" title="Part II. Programming with the Base API">Programming with the Base API</a>.
