can't locate db4o database file

Question

Hello I'm coding a simple CRUDE application that runs perfectly using JSF and DB4O. I can add and list all the entities normally without errors. I've used this code to persist the entities

bd = Db4oEmbedded.openFile(configuration, "db.data");
        bd.store(client);
        bd.commit();

the problem is that I cant locate the db.data file. I,ve done a search in the whole PC and still cant find it. soo where DB4O store those entities, how is it possible?? thank you.

It must be in your project execution path. Usually db4o file name is called with extension yap. Better you can use relative path to the database file like

String dbPath = "c:/db/project.yap"; // better read from project resource
EmbeddedObjectContainer openFile = Db4oEmbedded.openFile(dbPath);
