我正在使用Glassfish 4.1.1在Netbeans 8.0.1中创建一个使用Neo4j作为图形数据库的企业应用程序。我尝试使用JDBC驱动程序连接到JSF Managed Bean中的Neo4j：
public void neo4jCall() throws SQLException, ClassNotFoundException {
Class.forName("org.neo4j.jdbc.Driver");
Connection conn = DriverManager.getConnection("jdbc:neo4j://localhost:7474","neo4j","***");
try(Statement stmt = conn.createStatement()){
stmt.executeQuery("CREATE (n:Person { name : 'Lucas', title : 'Employee'})");
}
}
当我运行企业应用程序时，我获得以下异常：
