Hi,all:
i write a DAO in application, and i do a local junit test ,it seems ok.
public List<DesignElement> findByType(String type,PageModel pageModel)
{
PersistenceManager pm = PMF.get().getPersistenceManager();
Query q=pm.newQuery(DesignElement.class);
q.setFilter("type == typeparam");
q.declareParameters("String typeparam");
q.setRange(pageModel.getStartPos()-1, pageModel.getEndPos());
return (List<DesignElement>)q.execute(type);
}
but when i test it in local dev server,an empty List is return.However, i
check the page in the http://localhost:8080/_ah/admin,i can find some
DesignElement pojo on the list,if i just find all by this code:
public List<DesignElement> getAll()
{
PersistenceManager pm = PMF.get().getPersistenceManager();
Query q=pm.newQuery(DesignElement.class);
q.setRange(0,20);
return (List<DesignElement>) q.execute();
}
all the pojo can be returned.
so ,what's the problem?
by the way,i have a datastore-indexs.xml in the WEB-INF/ with
autoGenerate="true".
thanks for any help!!
