bill.cheng Apr 24, 2007 9:24 PMi deployed a project on jboss-4.2.when i started jboss,i encoutered a error.Below is the error. But i use JUnit for testing , all testcases run well.
My project includes two projects ,one is ejb project ,another is web project.I place ApplicationContext.xml and *.hbm.xml file on the root of ejb project. i added item of "contextConfigLocation" and "org.springframework.web.context.ContextLoaderList ener" to web.xml.
In test environment,I used a ClassPathXmlApplicationContext for obtaining a bean. TestCases run well.
Exception:

Java class:
I defined a Class like below for supporting generic type ?
import org.apache.commons.beanutils.PropertyUtils; import org.hibernate.Criteria; import org.hibernate.FlushMode; import org.hibernate.Query; import org.hibernate.criterion.CriteriaSpecification; import org.hibernate.criterion.MatchMode; import org.hibernate.criterion.Projection; import org.hibernate.criterion.Projections; import org.hibernate.criterion.Restrictions; import org.hibernate.impl.CriteriaImpl; import org.springframework.orm.ObjectRetrievalFailureException; import org.springframework.orm.hibernate3.support.HibernateDaoSupport; import org.springframework.util.Assert; import java.io.Serializable; import java.lang.reflect.InvocationTargetException; import java.util.ArrayList; import java.util.List; import java.util.regex.Matcher; import java.util.regex.Pattern; public class HibernateGenericDao extends HibernateDaoSupport { public <T> T get(Class<T> entityClass, Serializable id) { T o = (T) getHibernateTemplate().get(entityClass, id); if (o == null) throw new ObjectRetrievalFailureException(entityClass, id); return o; } ........
and defined another abstract class for some methods ,
import org.apache.log4j.Logger; import org.hibernate.Criteria; import com.gsww.util.GenericsUtils; import java.io.Serializable; import java.util.List; abstract public class HibernateAbstractDao<T> extends HibernateGenericDao { protected Logger log = Logger.getLogger(getClass().getName()); protected Class<T> entityClass; ......
public class PartnerAppDao extends HibernateAbstractDao<PartnerApp> { }
i deleted the hibernate.jar that jboss ships and added another hibernate.jar to jboss_home/server/default/lib. i guess it's not the problem of version .
Thank you very much!
