My hibernate configuration file was alright, the libs were in place (hibernate3.jar ,hibernate-annotations.jar) and so was the desired mapping path present...
mapping resource="com/bmb/model/BlogFeed.hbm.xml"
I was importing the proper classes for the annotationsimport javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
But the compiler continued to shout :
15:13:48,959 DEBUG BlogFeedDAO:62 - getting BlogFeed instance with id: 1
Entity retrieval failed.15:13:48,961 ERROR BlogFeedDAO:68 - get failed
org.hibernate.MappingException: Unknown entity: BlogFeed.class
Finally after hours, I realized the mistake and changed the code from orange to green...
public BlogFeed findById( java.lang.Integer id) {
log.debug("getting BlogFeed instance with id: " + id);
try {
//error BlogFeed instance = (BlogFeed) getSession().get("BlogFeed", id);
BlogFeed instance = (BlogFeed) getSession().get(BlogFeed.class, id);
return instance;
} catch (RuntimeException re) {
log.error("get failed", re);
throw re;
}
}
Having this -
Object org.hibernate.Session.get(Class arg0, Serializable arg1) throws HibernateException, forces the compiler to fetch the class (you can also specify the fully qualified class name).
