Hi,
 
We are having 4 entity files that are inter-related, The following code snippet uses entity files
 
1. public List<LoggerConfig> getLoggerConfigList() throws DaoException {
2.        logger.debug("getLoggerConfigList");
3.        OpenJPAEntityManager session = null;
4.        List<LoggerConfig> configList = new ArrayList<LoggerConfig>();
5        try {
6            session = ServiceLocator.getOpenJPASession("host");
7            OpenJPAQuery query = session.createNativeQuery("select * from  LOGGER_CONFIG where HOST_ID is null",LoggerConfigDTO.class);
8            List<LoggerConfigDTO> configDTOs =query.getResultList();
9            for (LoggerConfigDTO configDTO : configDTOs) {
10                //debug("getLoggerConfigList " + configDTO.toString());
11                configList.add(configDTO.toLoggerConfig());
12            }
13        } catch (Exception e) {
14            throw DaoException.getDaoException(e, logger);
15        } finally {
16            if (session != null && session.isOpen()) {
17                session.close();
18            }
19        }
20        return configList;
21    }
 
and while retriving the data in the above code at line number 8 throws the following exception.
Please find the Entity files as an attachement to this mail and following is the stack trace that
is getting displayed on the console. Please help us in resolving this issue.
