Hello,
I'am having trouble trying to find out what i am doing wrong, i
have a class user and a class role and a user has a collection of
roles, this kind of schema is working for other classes with the
same kind of relationship but not for this one.
OJB is trying to insert a null value in the column of the foreign
key id, but the role is in the collection of roles of the user
instance.
I'am using latest CVS OJB, my two classes are :
public class User implements INamable {
/**
* @ojb.field primarykey="true"
*/
private String id;
* /**
* @ojb.collection
element-class-ref="org.jys.clepsydra.data.users.Role"
* foreignkey="userId" auto-delete="true"
*/ private List<Role> roles = new
Vector<Role>();
*
/**
* @ojb.field
*/
private String url;
public User(String name) {
this.name = name;
}
public User() {
super();
}
/**
* @return Returns the roles.
*/
public List<Role> getRoles() {
return roles;
}
/**
* @param role
* @throws DataIntegrityException
*/
public void addRole(final Role role) throws
DataIntegrityException {
if (findRole(role.getDocumentBase()) != null) {
throw new DataIntegrityException(this + " already has a
role for " + role.getDocumentBase());
}
roles.add(role);
}
}
and
public abstract class Role implements IDataObject {
/**
* @ojb.field primarykey="true"
*/
private String id;
/**
* @ojb.reference foreignkey="documentBaseId" auto-update="none"
auto-delete="none"
*/
private DocumentBase documentBase;
public Role(DocumentBase base) {
super();
this.documentBase = base;
}
public Role() {
super();
}
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public DocumentBase getDocumentBase() {
return documentBase;
}
public boolean equals(Object object) {
if (object instanceof Role) {
return this.id.equals(((IDataObject) object).getId());
}
return false;
}
public String toString() {
return this.getClass() + " " + this.getDocumentBase();
}
}
and what i am trying to do is
Role admin = new Admin(getCurrentBase());
DataHelper.generateId(admin);
User t = getTestUser();
t.addRole(admin);
DataHelper.store(t);
If u have any clue about... Thank you.
