Id like to keep hibernate objects and mapping documents in a seperate directory from the class thats calling them. My application works fine and then I move all the .hbm.xml and hibernate classes to their own directory, change the .cfg.xml files to update this move and change the mapping files to reflect it as well and yet hibernate is still looking in the old directory (edu.asu.SFAO.Actions) rather than the new one (edu.asu.SFAO.Daos). A search through my entire project reveals that nowhere else is anything hardcoded with edu.asu.SFAO.Actions.Affiliate so its got to be coming from hibernate. What gives? Is there a way around keeping everything in the same directory?

There is no problem with mapping files being in different directories from the classes. That is how we have things set up. Just remember that if your cfg file has resource="X.hbm.xml" that it's going to look the file up as a resource, meaning it must be found relative to your classpath.

If you can't figure it out, post your files.

So all my hibernate classes and mapping files were in my Actions directory earlier and everything worked. I just created a directory under SFAO and called it Daos and put them all in there and then changed both of these files to point to Daos rather than Actions. However now I get that exception and its still looking for affiliate under Actions. What am I missing?

Oops, heres the other cfg file, the one that actually maps the Affiliate object

Ok, I'm guessing your classes are still in the Actions directory, and you just wanted to move your mapping files to the Daos directory. So what you probably have is a java class edu.asu.SFAO.Actions.Affiliate, and a mapping file that says
They need to match up. Change your mapping file back (Actions instead of Daos):

No, Id like to, and have, moved both.

Ah, sorry, I misunderstood your post.

Looks like you are somehow passing edu.asu.SFAO.Actions.Affiliate class to the Session.get() method (from the stack trace: at edu.asu.SFAO.Actions.GenerateMainAction.authExecute(GenerateMainAction.java:44) ). Maybe it's a rebuild problem? You've got classes in the old Actions package still hanging around?

Post your code if you still can't figure it out.

Exactly, except the odd thing is Im not passing that. Ive done a search through the entire project for that string and it doesnt exist. heres the code anyway. Heres the calling class

/*
* GenerateMainAction.java
*
* Created on September 01, 2004, 9:19 AM
*
* Struts default action which sets up the DAOs and Form and inserts tehm into
* the session
*/

package edu.asu.SFAO.Actions;

import javax.servlet.http.*;

import edu.asu.SFAO.Forms.*;

public ActionForward authExecute(ActionMapping mapping,

HttpServletRequest request,
HttpServletResponse response)
{

HttpSession session = request.getSession();
ServletContext context = servlet.getServletContext();
StudentForm sform = new StudentForm();
Affiliate affiliate;
Student student;
//use the asurite to get the affiliateid from the affiliate hibernate object, pass it
//to the student hibernate object to recieve a student object
org.hibernate.Session sess1 = HibernateUtil1.currentSession();
try
{
affiliate = (Affiliate) sess1.get(Affiliate.class,(String)session.getAttribute("asuriteid"));
student = (Student) sess1.get(Student.class,affiliate.getAffiliate());
}catch (Throwable ex)
{
//if the access failed log the error and add it the action errors before
//cleaning up and returning failure
HibernateUtil1.closeSession();
session.setAttribute("student", sform);
log.error("Affiliate access failed.", ex);
return (mapping.findForward("globalerror"));
}
HibernateUtil1.closeSession();
//if we got this far we have our student so set their name and asuid into the session form
sform.setAffilLastName(student.getAffilLastName());
sform.setAffilFirstName(student.getAffilFirstName());
sform.setAffilMiddleName(student.getAffilMiddleName());
sform.setAsuId(student.getAsuId());

session.setAttribute("student", sform);
return (mapping.findForward("success"));

}
}



Thanks for the help thus far, btw.

Its the Affiliate.class , isnt it. .. damnit. I guess I never understood that declaration, just took it from the hibernate docs. How would I specify the new location?

check your import for Affiliate:



I guarantee it's importing from Actions. You have a .class file for Affiliate in your Actions directory that you need to delete. That's why I suggested it might be a rebuild problem.

If you import Affiliate explicitly or do a clean rebuild, the problem will go away.

Yeah I got it, I just needed to explicitly declare asu.edu.SFAO.Daos.Affiliate

Stupid mistake, guess I just needed someone to bounce it off of. Thanks for the help
