олняю именованный запрос, используя jdbcTemplate.queryForList следующим образом:

List<Conversation> conversations = jdbcTemplate.queryForList(
            SELECT_ALL_CONVERSATIONS_SQL_FULL,
            new Object[] {userId, dateFrom, dateTo});

SQL-запрос:

private final String SELECT_ALL_CONVERSATIONS_SQL_FULL = 
    "select conversation.conversationID, conversation.room, " +
    "conversation.isExternal, conversation.startDate, " +
    "conversation.lastActivity, conversation.messageCount " +
    "from openfire.ofconversation conversation " +
    "WHERE conversation.conversationid IN " +
    "(SELECT conversation.conversationID " +
    "FROM openfire.ofconversation conversation, " +
    "openfire.ofconparticipant participant " +
    "WHERE conversation.conversationID = participant.conversationID " +
    "AND participant.bareJID LIKE ? " +
    "AND conversation.startDate between ? AND ?)";

Но при извлечении содержимого списка следующим образом:

for (Conversation conversation : conversations) {
builder.append(conversation.getId());
            builder.append(",");
            builder.append(conversation.getRoom());
            builder.append(",");
            builder.append(conversation.getIsExternal());
            builder.append(",");
            builder.append(conversation.getStartDate());            
            builder.append(",");            
            builder.append(conversation.getEndDate());
            builder.append(",");  
            builder.append(conversation.getMsgCount());
            out.write(builder.toString()); 
}

Я получаю ошибку:

java.util.LinkedHashMap cannot be cast to net.org.messagehistory.model.Conversation

Как мне преобразовать эту связанную карту в нужный объект?

Спасибо
