DAO and Entity Beans

[anandnatraj]

I am using a DAO Insert and trying to load the Remote Entity bean for the record which is just created under a single transaction as below

public MyEntity createSomeInfoMethod()
{
MyEntityHome entityHome = lookUp("MyEntity");
long id = SomeDAO.insertRecord(valueObject);
MyEntity mro = MyEntityHome.findByPrimaryKey(id);
return mro;
}

createSomeInfoMethod() is a stateless session method under a transaction control.
id is returned as the primaryKey of the record which is inserted using a DAO. (it is not null). But on the next line where I try to find the findByPrimaryKey I am getting following exception

javax.ejb.ObjectNotFoundException: No such entity!


MyEntityHome, MyEntity are the Home and Remote respectively for a CMP Bean. Am I missing anything basically? The HOME is looked up correctly. No issues in that.

Please help.

Hi,

there are some things you should keep in mind when you are doing things like this. ;-)

- Are you mixing user transactions with CMT?
- Is SomeDAO.insert() committing the data to the database?
- What are the CMT settings of the findByPrimaryKey() method?
- And what are the CMT settings of the createSomeInfoMethod()?

What I want to say is: Only if the DAO method has really committed the data, you are able to read them using an entity finder.

HTH,
