|
||
<p>There are several additional types of exceptions thrown in the Berkeley DB 3.0
|
||
Java API.</p>
|
||
<p>DbMemoryException and DbDeadlockException can be caught independently of
|
||
DbException if you want to do special handling for these kinds of errors.
|
||
Since they are subclassed from DbException, a try block that catches
|
||
DbException will catch these also, so code is not required to change.
|
||
The catch clause for these new exceptions should appear before the catch
|
||
clause for DbException.</p>
|
||
<p>You will need to add a catch clause for java.io.FileNotFoundException,
|
||
since that can be thrown by Db.open and DbEnv.open.</p>
|
||
<p>There are a number of smaller changes to the API that bring the C, C++
|
||
and Java APIs much closer in terms of functionality and usage. Please
|
||
refer to the pages for upgrading C applications for further details.</p>
