私はliferayを使用していますが、クラスとメソッドは次のとおりです。
EmployeeLocalServiceImpl.java
public class EmployeeLocalServiceImpl extends EmployeeLocalServiceBaseImpl {
/*
* NOTE FOR DEVELOPERS:
*
* Never reference this interface directly. Always use {@link com.mallyas.corpserver.emco.mis.service.EmployeeLocalServiceUtil} to access the employee local service.
*/
public List getEmployee() throws PortalException, SystemException, RemoteException {
return EmployeeFinderUtil.getEmployee();
}
...
}
EmployeeFinderImpl.java
public class EmployeeFinderImpl extends BasePersistenceImpl<Employee> implements EmployeeFinder {
// the name of the query
public static String GET_EMPLOYEE = "getemployee";
// the method which will be called from the ServiceImpl class
public List<Employee> getEmployee() throws SystemException {
Session session = null;
try {
// open a new hibernate session
session = openSession();
String fetchEmpsqlquery = CustomSQLUtil.get(GET_EMPLOYEE);
// create a SQLQuery object
SQLQuery empqueryObj = session.createSQLQuery(fetchEmpsqlquery);
// replace the "Book" in the query string with the fully qualified java class
// this has to be the hibernate table name
empqueryObj.addEntity("Employee", EmployeeImpl.class);
// Get query position instance
QueryPos qPos = QueryPos.getInstance(empqueryObj);
// fill in the "?" value of the custom query
// this is same like forming a prepared statement
//qPos.add(pattern);
// execute the query and return a list from the db
return (List<Employee>)empqueryObj.list();
/*
// use this block if you want to return the no. of rows (count)
int rows = 0;
Iterator<Long> itr = q.list().iterator();
if (itr.hasNext()) { Long count = itr.next();
if (count != null) { rows = count.intValue(); } }
return rows;
*/
} catch (Exception e) {
throw new SystemException(e);
} finally {
closeSession(session);
}
}
...
}
EmployeeFinder.java
@Transactional

public java.util.List<com.mallyas.corpserver.emco.mis.model.Employee> getEmployee()

このアプリケーションを実行すると、次のエラーが発生します。

何が間違っている可能性がありますか？上記の各クラスに@Transactionalを含めました。また、すべてのクラスから@Transactionalを削除しようとしましたが、それでも同じエラーが発生します。
