Hi,
I am a new user of hibernate. My problem is that I have got a POJO from some other guy and now I have to persist that so how should I do it?
I tried 2-3 ways but could not succeed and the challenge is that I can't make changes in that POJO so whatever I am to do is in hibernate mappings so please help me out for this.....

I tell you that I tried this way also

@org.hibernate.annotations.Type(
type="com.hs18.message.helper.enums.OrderStatus",
parameters = {
@Parameter(name="com.hs18.message.helper.enums.OrderStatus",value="toStatus"),
@Parameter(name="identifierMethod",value="status"),
@Parameter(name="valueOfMethod",value="value")
}
)

Here order status is my enum but when I go with this I get following exception when I try to load any object of that class in which I am using that enum:-

Hibernate: select orderstatu0_.EVENTORDERSTATUSRECORDRFNUM as EVENTORD1_0_0_, orderstatu0_.APPNAME as APPNAME0_0_, orderstatu0_.fromStatus as fromStatus0_0_, orderstatu0_.MODULENAME as MODULENAME0_0_, orderstatu0_.ORDERID as ORDERID0_0_, orderstatu0_.SUBORDERID as SUBORDERID0_0_, orderstatu0_.ORDERTIME as ORDERTIME0_0_, orderstatu0_.toStatus as toStatus0_0_ from EVENTORDERSTATUSRECORD orderstatu0_ where orderstatu0_.EVENTORDERSTATUSRECORDRFNUM=?

and when try to persist that Object from that class :-


Hibernate: insert into EVENTORDERSTATUSRECORD (APPNAME, fromStatus, MODULENAME, ORDERID, SUBORDERID, ORDERTIME, toStatus) values (?, ?, ?, ?, ?, ?, ?)

This is complete statcktrace ..........
Thanks in advance..........

Hi!

We use the enums in the same way and it works well.

Is your property marked with @Enumerated(STRING) ?

Best regards.

No......

My enum mapping doesn't start with this.....
My enum is like

OrderStatus{

DELIVERED(1,"delivered");
private int id; private String status;


private OrderStatus(id,status){
this.id = id;
this.status = status;
}

// some other code to retrieve value etc.
}


so I want to store that "id" value in DB means my object is :-

If user gets row from DB then he should get enum corresponding to that "id" stored in DB and when he goes to store that enum that particular enum id should be stored in DB.

This enum is being used in a POJO please have it in mind also..........

Ok. I see.

Then you should use the GenericEnumUserType described under http://community.jboss.org/wiki/Java5EnumUserType (Flexible solution - working version)

We use it the same way like you described it.



Best regards.
