Can you post the code that caused this? It usually happens when you work on invalid entities (i.e. those without a primary key).

Session session = null;
Transaction trx = null;

InOutTypes inouttypes = new InOutTypes();

String name = null;


name = (String) this.txtDocType.getText();

try {
session = HibernateUtil.getSession();
trx = session.beginTransaction();

inouttypes.setName(name);

session.save(inouttypes);

trx.commit();
session.close();
} catch (Exception e) {
e.getMessage();
} finally {
if (trx != null) {
trx = null;
}
if (session != null) {
session.clear();
session.close();
session = null;
}
}

return null; //"AddedDocType";

This is the code for inserting value in InOutTypes persistent class.
There are only two fields.
1.inOutTypeId rimary Key
2.Name

So please solve my problem ASAP

<id name="inOutTypeId" type="int">
<column name="IN_OUT_TYPE_ID" />
<generator class="assigned" />
</id>
<property name="name" type="string">
<column name="NAME" length="100" not-null="true">
<comment></comment>
</column>
</property>

inOutTypeId is auto incremented field.

inOutTypeId is auto incremented field.

Not according to your mapping. You are using the assigned strategy, i.e. you need to assign the ID yourself. Try using native.

But we generate Persistent classes and hbm files by reverse engineering.

that why generator class of inoutTypeId is assigned.

we only use those hbm and orm.

but is it right way to change assigned to native?

I just check it but there is still problem.

If you are using an assigned id generation strategy you will need to assign an id. Simple as that. If you reverse engineering tool has given you something else I'd check the tools documentation, see if you need to do something to properly generate a different strategy.

Actually i get Exception after change to native.

an assertion failure occured (this may indicate a bug in Hibernate, but is more likely due to unsafe use of the session)

Check your DDL. Does the table have a primary key? Is it really autoincrement?

AssertionFailure? Can you show us the stacktrace?

Thanks a lot...

My problem is solved by changing aasigned to native generator class of inoutTypeId.


can you solve my another problem?

java.lang.ClassCastException: java.lang.String cannot be cast to java.lang.Integer

This is occured when there is a foreign key is in table which is add to the table using hibernate.


I already try as following...

Users user = new Users();

user.setUserId((Integer)this.dropDown1.getValue());

and by another way...

user.setUserId((Integer.parseInt)(this.dropDown1.getValue());

so can you solve my problem please....

What type of object does your collection hold? According to the error, it is a String, so this:

will not work.

This:

is not valid java so wont work either.

After changing generator class to native, i already had an |org.hibernate.AssertionFailure: InvocationTargetException|. So how can i fix it.

Thanks
