evict does not work

Hi,

I'm trying to evict an object. It is an object (DirectoryEntry) that have some attributes (Descriptor).

I get this object from the DB and I want to evict it to add the descriptor and put the directory entry to the session scope. But I don't want that the descriptor is saved in the DB.

I am in a spring context web application.
Here is the code :

Code:

directoryEntry = (DirectoryEntry) this.dataAccessObject.findDirectoryEntryByInboxURL(inboxURL);
this.dataAccessObject.evict(directoryEntry);
directoryEntry.setDescriptor(new Descriptor());

When I do this, the descriptor is saved in the DB...

If you can help me...

Thank you...

Code:

session.evict(directoryEntry );

if(session.contains(directoryEntry)){
  System.out.println("you're saying this prints?");
}

Thank for your help.

I am in a spring context.
So here is my dataAccessObject class :

Code:

import org.springframework.orm.hibernate3.support.HibernateDaoSupport;

public class HibernateDataAccessObject extends HibernateDaoSupport;

And here is the evict method of this class :

Code:

   public void evict(Object o) throws CoreException {
      
      try {
         
         getHibernateTemplate().evict(o);
         
      } catch (DataAccessException e) {
         
         e.printStackTrace();
         
         CoreException ce = new CoreException();
         ce.setErrorCode(IDAOExceptionConstants.ERROR_CODE_GENERAL_FAILURE);
         ce.initCause(e);
         ce.setStackTrace(e.getStackTrace());

         throw ce;
      }
   }

When I do it, no exception appear...
