can´t find rsadapterspi.jar to use WSJdbcConnection
<p><strong>WSJdbcConnection</strong>, <strong>WSJdbcUtil</strong> these two showing errors in Web sphere 7 
but some systems working fine with same configuration some systems not working </p>

<pre><code>        EWFUtil util=new EWFUtil();
        connection=util.getConnection();

        oracleConnection = (OracleConnection)WSJdbcUtil.getNativeConnection((WSJdbcConnection) connection);
</code></pre>
