user.java:

@persistencecapable(table = "user_login") public class user_login {   @primarykey @column(name="user_id") private integer user_id=0; @column(name="user_profile_name") private string user_profile_name=null;  @column(name="user_email") private string user_email=null; @column(name="user_contact") private string user_contact=null; @column(name="user_name") private string user_name=null; @column(name="user_password") private string user_password=null; @column(name="user_role_id") private integer user_role_id=0; 

my dependencies are: datanucleus-core, datanucleus-rdbms, datanucleus-api-jdo, datanucleus-jdo-query, jdo-api

table recognition db failure. not sure persistence. please help!!
