      <p>
        Before continuing, it is useful to spend a few moments on exception
        handling in DB with the 
        <span>java</span>.
    </p>
      <p>
        
        <span>Most</span>
        DB methods throw 
            
            <tt class="classname">DatabaseException</tt>
        in the event of a serious error. 
        
        
        <span>
            So your DB code must either catch this exception or declare it
            to be throwable. Be aware that <tt class="classname">DatabaseException</tt> extends 
            <tt class="classname">java.lang.Exception</tt>. For example:
        </span>
    </p>
      <a id="java_intro1"></a>
      <pre class="programlisting">import com.sleepycat.db.DatabaseException;

...
try 
{
    // DB and other code goes here
}
catch(DatabaseException e)
{
  // DB error handling goes here
} </pre>
      <p>
        You can obtain the DB error number for a
         
        <tt class="classname">DatabaseException</tt> 
        by using
        
        <span>
            <tt class="methodname">DatabaseException.getErrno()</tt>. 
            You can also obtain any error message associated with that error
            using <tt class="methodname">DatabaseException.getMessage()</tt>.
        </span>
    </p>
    </div>
    <div class="navfooter">
      <hr />
      <table width="100%" summary="Navigation footer">
