java - Hibernate @Embeddable class throws "SQLServerException: Invalid column name" for column that is not referenced -

i've been tearing hair out one. have class pulling object so:

public userdto getuser(string login) {     string jql = "select entity user entity  entity.abcuserid = :userid ";      query query = _entitymanager.createquery(jql)             .setparameter("userid", login);     try     {         object user = query.getsingleresult();         return ((user) user).extractobject();     }     catch(noresultexception e)     {         log.error(e.getmessage());         return null;     }  } 

with class it's pulling:

@entity @table(name="abc_user") public class user implements serializable,entityobject<userdto> {  private static final long   serialversionuid    = 1l;  private long id; private string abcuserid; private company company; private list<userpreference> userpreferences;  @id @generatedvalue public long getid() {     return id; }  public void setid(long id) {     this.id = id; }  @manytoone(fetch=fetchtype.lazy) @joincolumn(name="company_id", nullable=false) public company getcompany() {     return company; }  public void setcompany(company customer) {     this.company = customer; }  /**  * @return userpreference  */ @elementcollection(fetch=fetchtype.eager) @jointable(name="abc_user_preferences") @cascade(value={org.hibernate.annotations.cascadetype.all}) public list<userpreference> getuserpreferences() {     if(userpreferences == null)     {         userpreferences = new arraylist<userpreference>();     }     return userpreferences; }  /**  * @param userpreference userpreference set  */ public void setuserpreferences(list<userpreference> userpreferences) {     this.userpreferences = userpreferences; }  /**  * @return abcuserid  */ @column(name="abc_user_id", length=10, nullable=false) public string getabcuserid() {     return abcuserid; }  /**  * @param abcuserid abcuserid set  */ public void setabcuserid(string abcuserid) {     this.abcuserid = abcuserid; } 

which references embeddable object:

@embeddable public class userpreference implements serializable { private static final long   serialversionuid    = 1l;  private string prefkey; private string prefvalue;  public userpreference() {}  public userpreference(string key, string value) {     this.prefkey = key;     this.prefvalue = value; }  @column(nullable=false, length=255) public string getprefkey() {     return prefkey; } public void setprefkey(string key) {     this.prefkey = key; } @column(nullable=false, length=1048576) public string getprefvalue() {     return prefvalue; } public void setprefvalue(string value) {     this.prefvalue = value; } } 

so, long winded chunk of code out of way stuff censored, doesn't work. every time try pull user database, throws "sqlserverexception: invalid column name 'user_id'". user_id never referenced in project (i've checked), it's always abc_user. can watch object pulled in eclipse debugger, gets point of adding list of userpreferences , falls apart. if comment out userpreferences portion of user class, pulls (and breaks somewhere else uses them).

what missing?

see following portion of code

@column(name="abc_user_id", length=10, nullable=false) public string getabcuserid() {     return abcuserid; } 

check if table has column name 'abc_user_id'. then, try placing code before @jointable portion
