Should I configurate orientdb-server-config.xml or something else? This is the code what I use to connect

public static void openDataBase() { 
    ODatabaseDocumentTx db = new ODatabaseDocumentTx("plocal:/database/bugsac");
    db.open("admin", "admin");
    try {
        System.out.println(db.getName());
    } finally {
      db.close();
    }

The error occur here db.open("admin", "admin"); The connection goes without errors. Could you suppose what is the problem?

Answer 1

The error is clear:

java.lang.ClassNotFoundException: org.iq80.snappy.Snappy

Have you included snappy*.jar in your classpath?
