Covertir un CLOB a String (java oracle)

Os dejo este pedacito de código que convierte un CLOB de oracle a un String:

private String CLOBToString(CLOB cl) throws IOException, SQLException
{
if (cl == null)
return "";
StringBuffer strOut = new StringBuffer();
String aux;
BufferedReader br = new BufferedReader(cl.getCharacterStream());
while ((aux=br.readLine()) != null)
{
strOut.append(aux);
}
return strOut.toString();
}
