<P>
This information describes the DbException class and how it is
used by the various Berkeley DB classes.</p> <p>
Most methods in the Berkeley DB classes throw an exception when an
error occurs. A DbException object contains an informational
string, an errno, and a reference to the environment from which
the exception was thrown.</p> <p>
Some methods may return non-zero values without issuing an
exception. This occurs in situations that are not normally
considered an error, but when some informational status is
returned. For example, <A HREF="../../../com/sleepycat/db/Db.html#get(com.sleepycat.db.DbTxn, com.sleepycat.db.Dbt, com.sleepycat.db.Dbt, int)"><CODE>Db.get</CODE></A>
returns <a href="../../../../ref/program/errorret.html#DB_NOTFOUND">
Db.DB_NOTFOUND</a> when a requested key does not appear in the
database.</p>
