load hibernate.cfg.xml in existing java project

Question

I try to load hibernate.cfg.xml in a submodule (ssf/samples/customcontroller) of an existing project. For this project there exists a build.xml which builds and deploys the proj

Answer 1

See where hibernate.cfg.xml resides in the build folder (in which eclipse compiles classes).

If hibernate.cfg.xml in the root of the build folder

SessionFactory sessionFactory = new Configuration().configure().buildSessionFactory();

If hibernate.cfg.xml in the build_folder/some_path/some_other_path/hibernate.cfg.xml

SessionFactory sessionFactory = new Configuration()
    .configure("/some_path/some_other_path/hibernate.cfg.xml")
    .buildSessionFactory();

You can use path without the leading /, because of Hibernate deletes it anyway (it is even more correct way, but not clear, because of a path to a resource has the leading / usually)

SessionFactory sessionFactory = new Configuration()
    .configure("some_path/some_other_path/hibernate.cfg.xml")
    .buildSessionFactory();

This code shows how Hibernate tries to load hibernate.cfg.xml

public InputStream locateResourceStream(String name) {
        // first we try name as a URL
        try {
            log.tracef( "trying via [new URL(\"%s\")]", name );
            return new URL( name ).openStream();
        }
        catch (Exception ignore) {
        }

        try {
            log.tracef( "trying via [ClassLoader.getResourceAsStream(\"%s\")]", name );
            final InputStream stream = getAggregatedClassLoader().getResourceAsStream( name );
            if ( stream != null ) {
                return stream;
            }
        }
        catch (Exception ignore) {
        }

        final String stripped = name.startsWith( "/" ) ? name.substring( 1 ) : null;

        if ( stripped != null ) {
            try {
                log.tracef( "trying via [new URL(\"%s\")]", stripped );
                return new URL( stripped ).openStream();
            }
            catch (Exception ignore) {
            }

            try {
                log.tracef( "trying via [ClassLoader.getResourceAsStream(\"%s\")]", stripped );
                final InputStream stream = getAggregatedClassLoader().getResourceAsStream( stripped );
                if ( stream != null ) {
                    return stream;
                }
            }
            catch (Exception ignore) {
            }
        }

        return null;
    }
