As It seems your entity Country has not been enhanced by the enhancer. If you are using Intellij Idea there is an option in the project's properties dialog which specifies which packages to be enhanced.

You can get more information about enhancement from http://db.apache.org/jdo/enhancement.html

I have a Entity class Country.


The very first time when i am running my app this is not created in datastore.
So my code:
try{
 String query = "select from " + BloodDonorCountryList.class.getName() +
          " where  countryName == \"" + country.toLowerCase() + "\"";
log.info <http://log.info>("Query is:" + query);
List<BloodDonorCountryList> countryList = (List<BloodDonorCountryList>) pm.newQuery(query).execute();
log.info <http://log.info>("returning: :::::::::::::::::::::::::");
          if(countryList.isEmpty())
 return null;
          return countryList;
}catch(Exception e){
log.severe("Method: addBloodDonorCountry");
log.severe(e.getClass().getName() + " " + e.getMessage());
throw new CommandExecuteException("Problem while querying country list.");
}


throws exception saying:
EVERE: javax.jdo.JDOUserException Persistent class "Class vik.sakshum.Country does not seem to have been enhanced. You may want to rerun the enhancer and check for errors in the output." has no table in the database, but the operation requires it. Please check the specification of the MetaData for this class.

So how to avoid this exception? Or in other words how to detect if this is the case.

Thankx and Regards
