"message": "could not execute statement; nested exception is org.hibernate.exception.GenericJDBCException: could not execute statement",

whenever I try to add something into my table documents using the userId as a parameter I get this error message in postman using this "localhost:9293/SpringMVC/servlet/documents/add?userId=2"
could not execute statement; nested exception is org.hibernate.exception.GenericJDBCException: could not execute statement

Please note that user_id must be the foreign key in your document table if it is the different field, then use that one.

JPA mapping table could not delete

I have entity Account, Role, AccountRole.

}
To create account with role is OK.
There is a problem in update.
I want to delete the existing Role and only add the changed Role when the Role of the Account is changed. However, existing data is not deleted from the AccoutRole table.
How can I solve the problem?

A couple of ideas:
Thought 1: Try using cascade
Yes, JPA 2.0 should handle this with orphanRemoval = true, but let's just see if that works. I think that it is not because you aren't creating an orphan here. The mapping is still "valid" from a relational perspective.
#OneToMany(mappedBy = "account", cascade = CascadeType.ALL) // or CascadeType.REMOVE
private List<AccountRole> accountRoles = new ArrayList<>();
Thought 2: Try setting the account roles to an empty hashmap instead first:
account.setAccountRoles(new HashMap<AccountRole>());
account.getAccountRoles().add(accountRole);;

Declaring class is not found in the inheritance state hierarchy: UserAccount

I'm using servlets with JPA+Hibernate). I don't understand the error, unless I've tried other solutions suggested in this forum. In fact, I don't want to store the UserAccount class as an entity; but I just want to declare it in the Utilisateur class (the Ids of the Utilisateur class are declared in the useraccount class).
My code :

#Column(name = "particularRules")
private boolean particularRules;
public Utilisateur(UserAccount pAccount, Civility pCivility,
Address pAddress, Contact pContact, List<String>
pSessions,

this.userAccount = pAccount;
this.civility = pCivility;

this.contact = pContact;
this.sessions = pSessions;

You must use an Embedded Primary Key.
See the answer to this question here in Stackoverflow How to create and handle composite primary key in JPA.
Best regards!

It may occur when Embedded Primary Key contains #EmbeddedId. Sub-composite key should be annotated with #Embedded instead.

OneToOne ids generated error

i have this error nested exception is org.hibernate.id.IdentifierGenerationException: ids for this class must be manually assigned before calling save(): app.Spring.domain.UserDetails.
I now have this user table and in profile i want to edit this UserDetails.
i was trying with GeneratedValue but this doing random id that not associate with user_id also checked generator but this method also dont work.There is so many options so i am lost now.Can someone show some method to mapp this two entities?

I don't know how to do this with annotations but you might try to manually assign the (hopefully then already present) id fetched from user in the UserDetails entity in the #PrePresist annotated method.

Hibernate Spring Webflow One to Many Duplicate Primary Key

ive been working on this for a while and can't seem to figure it out except that at some point it was working as was intended. I have two objects, a User which can be associatted with multiple addresses. Saving a new user and address together works just fine, but when i try to add a new address to an existing User i get an error about duplicate primary keys for User table. I guess it has something to do with the configuration in hibernate trying both unidirectional and bidirectional.
Below are any relevant files. Thanks of your help!
