ODatabaseException: Database instance is not set in current thread

Question

I am new in OrientDB and use orientdb-community-1.7.4 version. I have two projects. Project A is used for manipulation with orientdb database (CRUD operation etc). Project B is a maven project (Liferay portlet) which includes Project A as a dependency.

In project B I create new Edge object, which is persisted in database. Then I want to get this object from database:

ApplicationContext appC = new ClassPathXmlApplicationContext("ApplicationContext.xml");
OrientDatabaseConnectionManager connMan = (OrientDatabaseConnectionManager) appC.getBean("orientConnectionManager");
OrientGraph graph = connMan.getGraph();
Edge edge = graph.getEdge("#37:20");

But I get this error. When I tried to get Edge object in Project A, I didn't get this error.

    /**

     */

    public class OrientDatabaseConnectionManager {
        private OrientGraphFactory factory;

        public OrientDatabaseConnectionManager(String path, String name, String pass) {
            factory = new OrientGraphFactory(path, name, pass).setupPool(1,10);
        }

        /**
         * Method returns graph instance from the factory's pool.
         * @return 
         */

        public OrientGraph getGraph(){
            return factory.getTx();
        } 

    }

Answer 1

I think this is a bug in orientdb, because when I tried it on 32-bit Windows 7, it works, but on OS X I get this error.

This solution works also on OSX.
