hibernate oracle identifier is too long ORA-00972

Question

Im stuck with this problem. The database schema is provided by someone else so I cant simply change names. I tried add everywhere proper annotations, maybe I'm missing something (obvious)?

Here is my full mapping (quite many classess), I'll ommit getter/setters.

The problem is when hibernate is trying to get all List<ControlRuleAttrib> controlRuleAttribs

Controle Rule

@Entity
@Table(name = "CONTROL_RULE")
public class ControlRule implements Serializable {
 @Id
 @GeneratedValue(strategy = GenerationType.IDENTITY)
 @Column(name = "CONTROL_RULE_ID")
 private Long id;
 @ManyToOne(fetch = FetchType.LAZY)
 @Cascade(CascadeType.ALL)
 @JoinColumn(name = "CONTROL_RULE_TYPE_ID")
 @ForeignKey(name = "CONTROL_RULE_TYPE_ID")
 private ControlRuleType controlRuleType;
 @Column(name = "JOB_NM")
 private String jobname;
 @Column(name = "LIBRARY_NM")
 private String libraryname;
 @Column(name = "TABLE_NM")
 private String tablename;
 @Column(name = "COLUMN_NM")
 private String columnname;

 @OneToMany(fetch = FetchType.LAZY)
 @Cascade(CascadeType.ALL)
 @JoinTable(name = "CONTROL_RULE_ATTRIB", joinColumns = {
  @JoinColumn(name = "CONTROL_RULE_ID", nullable = false, updatable = false)
 })
 private List < ControlRuleAttrib > controlRuleAttribs;
}

ControlRuleAttrib

@Table(name = "CONTROL_RULE_ATTRIB")
@Entity
public class ControlRuleAttrib {
 @EmbeddedId
 private ControlRuleAttribPK controlRuleAttribPK;

 @Column(name = "ATTRIBUTE_VALUE")
 private String attributeValue;
}

ControleRuleAttribPK Question here is, is it possible to somehow get Entity ControlRuleAttribType from ControlRuleAttrib? As you can see below ControlRuleAttribTypeId is the id of ControleRuleAttribType. I'd like to get whole object isteand of integer.

@Embeddable
public class ControlRuleAttribPK implements Serializable {
 @Column(name = "CONTROL_RULE_ID")
 private Long controlRuleId;

 @Column(name = "ATTRIBUTE_SEQ_NUM")
 private Integer attributeSeqNum;

 @Column(name = "CONTROL_RULE_ATTRIB_TYPE_ID")
 private Integer controlRuleAttribTypeId;
}

ControleRuleAttribType

@Entity
@Table(name = "CONTROL_RULE_ATTRIB_TYPE")
public class ControlRuleAttribType implements Serializable {
 @Id
 @GeneratedValue(strategy = GenerationType.IDENTITY)
 @Column(name = "CONTROL_RULE_ATTRIB_TYPE_ID")
 private Integer id;
 @Column(name = "CONTROL_RULE_ATTRIB_TYPE_NM")
 private String typename;
 @Column(name = "CONTROL_RULE_ATTRIB_TYPE_DESC")
 private String typedesc;

 @ManyToOne(fetch = FetchType.LAZY)
 @Cascade(CascadeType.ALL)
 @JoinColumn(name = "CONTROL_RULE_TYPE_ID")
 @ForeignKey(name = "CONTROL_RULE_TYPE_ID")
 private ControlRuleType controlruletype;
}

ControleRuleType

@Entity
@Table(name = "CONTROL_RULE_TYPE")
public class ControlRuleType implements Serializable {
 @Id
 @GeneratedValue(strategy = GenerationType.IDENTITY)
 @Column(name = "CONTROL_RULE_TYPE_ID")
 private Integer id;
 @Column(name = "CONTROL_RULE_TYPE_NM")
 private String typename;
 @Column(name = "CONTROL_RULE_TYPE_DESC")
 private String typedesc;
}

EDIT

Here is stacktrace:

https://gist.github.com/a30dd9ce534d96bb9a97

As you'll find out, it fails here:

at com.execon.controllers.main.MainPageController.getMainPage(MainPageController.java:33) [classes:]

and this is it:

List<ControlRule> list = SessionFactoryUtils.openSession(
    sessionFactory ).createQuery( "from ControlRule" ).list();
System.out.println( list );

every object which mapping I added, has toString() method declared like this:

@Override
public String toString()
{
    String s = "ControlRule{";
    s += "id=" + id.toString();
    s += ", controlRuleType=" + controlRuleType;
    s += ", jobname='" + jobname + '\'';
    s += ", libraryname='" + libraryname + '\'';
    s += ", tablename='" + tablename + '\'';
    s += ", columnname='" + columnname + '\'';
    s += ", controlRuleAttribs=" + controlRuleAttribs;
    s += '}';
    return s;
}

And hibernate request:

Help please :)

EDIT 2

Well after reading @Jens answer, I did some changes in the code. First I did as you wrote and it gave error:

org.hibernate.AnnotationException: A Foreign key refering com.execon.models.controlrules.ControlRuleAttrib from com.execon.models.controlrules.ControlRule has the wrong number of column. should be 3

I guess this is right, as I have composite primary key.

Then I tried it this way:

@OneToMany(fetch = FetchType.LAZY)
@Cascade(CascadeType.ALL)
@JoinTable(name = "CONTROL_RULE_ATTRIB",
        joinColumns = {
                @JoinColumn(name = "CONTROL_RULE_ID", nullable = false, updatable = false)
        },
        inverseJoinColumns = {
                @JoinColumn(name = "CONTROL_RULE_ID", nullable = false, updatable = false),
                @JoinColumn(name = "CONTROL_RULE_ATTRIB_TYPE_ID", nullable = false, updatable = false),
                @JoinColumn(name = "ATTRIBUTE_SEQ_NUM", nullable = false, updatable = false)
        })
private List<ControlRuleAttrib> controlRuleAttribs;

Quite close but it gives me the following exception:

Repeated column in mapping for collection..

So finally I removed

joinColumns = 
{
    @JoinColumn(name = "CONTROL_RULE_ID", nullable = false, updatable = false)
}

And everything compiled except that when I try to reach collection, Hibernate is doing following query:

https://gist.github.com/c88684392f0b7a62bea5

The last line, is controlrul0_.CONTROL_RULE_CONTROL_RULE_ID=? while it should be controlrul0_.CONTROL_RULE_ID=?.

Is there anyway I can make it work? :/

Solution

After struggling with this for last few hours I finally make it working within my project. The thing I did was this:

ControlRule

@OneToMany(fetch = FetchType.LAZY, mappedBy = "controlRuleAttribPK.controlRuleId")
@Cascade(CascadeType.ALL)
private List<ControlRuleAttrib> controlRuleAttribs;

Basically pointing that the collection should use controlRuleId from composite primary key. So far its working great!
