Hi.

I cloned a project at github.com/mtaal/texo/tree/master/org.eclipse.emf.texo.example1.rcp and testing it.

1.
When I save objects using org.eclipse.emf.texo.example1.rcp.controller.Controller class,
database created and data persisted well.

2.
But when I access dao classes, following exception occured.

// Code
			MusicModelPackage.initialize();
			
			org.eclipse.emf.texo.example1.rcp.persistence.model.music.Album album2 = new org.eclipse.emf.texo.example1.rcp.persistence.model.music.Album();
			album2.setName("New Album");
			album2.setReleaseDate(new Date());
			
			final AlbumDao albumDao = DaoRegistry.getInstance().getDao(AlbumDao.class);
			albumDao.insert(album2);


// Exception

Hi Bakjwis,
I don't know the example1.rcp that well. But the error indicates that the texo dao layer can not find the entity manager
and does not have a name.

This wiki page provides some info on registering the entitymanagerfactory with Texo:
https://wiki.eclipse.org/Texo/EntityManagerHandling
