Any help will be appreciated for this issue

Here is the EntityManagerFactory I am trying to create

@Bean(name="emfJpaNeo4j")
public EntityManagerFactory emfJpaNeo4j() {
Map<String, Object> properties = new HashMap<String, Object>();
// pass the type
properties.put( Neo4jProperties.DATASTORE_PROVIDER, "neo4j_http" );
properties.put( Neo4jProperties.HOST, "localhost:7474" );
//properties.put( Neo4jProperties.DATABASE, "tutorial" );
properties.put( Neo4jProperties.DATABASE_PATH, "C:/neo4j/database/tutorial" );
properties.put( Neo4jProperties.USERNAME, "neo4j" );
properties.put( Neo4jProperties.PASSWORD, "demo2017" );

EntityManagerFactory emf = Persistence.createEntityManagerFactory( "60Capital-neo4j-ejbPU", properties );

return emf;
}

And persistent.xml
mysql works ok
