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="../api_java/db_get.html">Db.get</a> returns DB_NOTFOUND when a requested key does not appear in the database. </tt> <table width="100%"><tr><td><br></td><td align=right> <a href="../api_java/c_index.html"><img src="../images/api.gif" alt="API"></a><a href="../reftoc.html"><img src="../images/ref.gif" alt="Ref"></a> </td></tr></table> <p><font size=1><a href="http://www.sleepycat.com">Copyright Sleepycat Software</a></font> </body> </html>
