Hi,
I don't see the a field called cvgsAppenderProperties in the
com.server.dao.config.AppenderConfigDTO class. Are you sure you sent
the same code that you're having problems with?

Hello Patrick,
Please help us in resolving the below problem:
We are having 4 entity files that are inter-related and one dao file,
1. LoggerConfigDTO
2. LoggerAppenderMapppingDTO
3. AppenderConfigDTO
4. AppenderPropertyDTO
5. ConfigDAOImpl
The following are the relationships among the four entities :
1. LoggerConfigDTO
OneToMany relation with LoggerAppenderMappingDTO
2. LoggerAppenderMappingDTO
ManyToOne Relation with LoggerConfigDTO
ManyToOne relation with AppenderConfigDTO
3. AppenderConfigDTO
OneToMany Relation with LoggerAppenderMappingDTO
OneToMany Relation with AppenderPropertyDTO
4. AppenderPropertyDTO
ManyToOne Relation with AppenderConfigDTO
We have mapped all these relationships with annotations in the DTO files,
and compiled successfully
The following code snippet that 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.
