I’m getting this message when trying to use the findByExample of a DAO automatically created by Hibernate Tools. From what I readed this “FWK005 parse may not be called while parsing” thing could be caused because it’s not thread safe, but i have no clue on how to solve this

Any help would be apreciated

mrchocobo ,

Hibernate can’t find Acto.hbm.xml .Check if it is in correct package (in source folder) and that you have added this mapping in hibernate.cfg.xml

Well, of course that was the first thing I checked, sorry for not saying it. All mapping files are under the package es.ucm.audiovisuales.server and this is my configuration file, which also says the mapping resources are under es/uc3m/audiovisuales/server/

That’s why I think the fact it can’t read from the mapping file is not because it couldn’t find it, but because of something related, for some reason, with the SAXReader.

So I don’t have a clue on what is causing this. I bet it’s an stupid thing but it’s getting on my nerves 🙁

This is the HibernateSessionFactory:
```

import org.hibernate.cfg.Configuration;

/**
 * Configures and provides access to Hibernate sessions, tied to the current

     * as Hibernate uses #resourceAsStream style lookup for its configuration
     * file. The default classpath location of the hibernate config file is in
     * the default package. Use #setConfigFile() to update the location of the
     * configuration file for the current session.
     */
    private static String CONFIG_FILE_LOCATION = "/es/uc3m/audiovisuales/server/hibernate.cfg.xml";

    private static final ThreadLocal threadLocal = new ThreadLocal();

    private static Configuration configuration = new Configuration();

    private static org.hibernate.SessionFactory sessionFactory;

    private static String configFile = CONFIG_FILE_LOCATION;

    private HibernateSessionFactory() {
    }

    /**

        if (session == null || !session.isOpen()) {
            if (sessionFactory == null) {
                rebuildSessionFactory();
            }
            session = (sessionFactory != null) ? sessionFactory.openSession()
                    : null;
            threadLocal.set(session);
        }

        return session;
    }

    /**
     * Rebuild hibernate session factory
     *

    public static void rebuildSessionFactory() {
        try {
            configuration.configure(configFile);
            sessionFactory = configuration.buildSessionFactory();
        } catch (Exception e) {
            System.err.println("%%%% Error Creating SessionFactory %%%%");
            e.printStackTrace();
        }
    }

    /**

     *

     */
    public static void closeSession() throws HibernateException {
        Session session = (Session) threadLocal.get();
        threadLocal.set(null);

        if (session != null) {
            session.close();
        }
    }

    /**
     * return session factory
     * 
     */
    public static org.hibernate.SessionFactory getSessionFactory() {
        return sessionFactory;
    }

    /**

     * 
     * session factory will be rebuilded in the next call
     */
    public static void setConfigFile(String configFile) {
        HibernateSessionFactory.configFile = configFile;
        sessionFactory = null;
    }

    /**
     * return hibernate configuration
     * 
     */
    public static Configuration getConfiguration() {
        return configuration;
    }

}
```
Maybe it has something to do with using thread-local variables?
I don’t know, I’m just saying the first thing that come into my mind. I really don’t know hot to solve this, so any help would be greatly appreciated 🙁

OK, I found the reason. It was the comment at the beginning of the file:
<!–Mapping file autogenerated by MyEclipse – Hibernate Tools–>

The parser didn’t seem to like that one for some reason 😐

mrchocobo,

This is error from some strange parser.
I suppose that you have configured some specific parser.How you call your application ?

– standalone application in java/hibernate project (I suggest that always try this)
– in some application server (is yes, what apps server)
or
– hql editor

What is jdk, eclipse and MyEclipse version ?

I think that your problem isn’t comment.It can be some threading problem in application server.

Regards,
