i'm not able solve new exception when deploy war tomcat 8 (using mvn tomcat:run-war command).

here pasted exception:

can please give me advice solve issue?

thanks.

you can't use mappedby on both sides of association.

it incorrect

/** user token. */ @onetoone(mappedby = "user") private token token;   @onetoone(mappedby = "token") private user user; 

firstly, should decide persistent owner of association ( table have foreign key). example, if user have foreign key column fk_token token identifier

@entity @table(schema = "mistergift", name = "users") public class user {      /** user token. */     @onetoone     @joincolumn(name = "fk_token")     private token token;  }  @entity @table(schema = "mistergift", name = "user_token") public class token {      @onetoone(mappedby = "token", fetch = fetchtype.lazy)     private user user;  } 

if token have foreign key column fk_user user identifier

@entity @table(schema = "mistergift", name = "users") public class user {      /** user token. */     @onetoone(mappedby = "user")     private token token;  }  @entity @table(schema = "mistergift", name = "user_token") public class token {      @onetoone(fetch = fetchtype.lazy)     @joincolumn(name = "fk_user")     private user user;  } 

updated

the exception rised @ line onetoonesecondpass.dosecondpass(map) because of othersideproperty == null. hibernate try find token.user property among persistent classes known him , fail. hibernate doesn't consider token persistent. reasons can be

1. token doesn't have @entity annotation.

2. token not mapped in hibernate.cfg.xml.

3. incorrect scanning of packages persistents, @magik reported.

hibernate, has unclear and, may be, incorrect error message issue.
