<h1>Description</h1>
<p>This manual page describes the DbException class and how it is used by
the various Berkeley DB classes.
<p>Most methods in the Berkeley DB classes throw an exception when an error occurs.
A DbException object contains an informational string and an errno. The
errno can be obtained using DbException.get_errno. Since DbException
inherits from java.lang.Exception, the string portion is available using
toString().
<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="../../db4-devel-4.1.25/api_java/db_get.html">Db.get</a>
returns DB_NOTFOUND when a requested key does not appear in the database.
