Hi Martin,
The table and column annotations are processed by
AnnotationPersistenceMappingParser.java and are then stored in the
MappingRepository. You can get the MappingRepository from
JDBCConfigurationImpl by calling getMappingRepositoryInstance().

ClassMapping mapping = (ClassMapping) ((JDBCConfiguration)conf)
.getMetaDataRepositoryInstance().getMetaData(entityClass,
getClass().getClassLoader(), true);
Table table = mapping.getTable().getName();
Column[] cols = mapping.getField(fieldName).getColumns();
Column col = cols[0];

overrides.
Hope this helps,
