Deleting a persistant object not resulting exception but not deleting the data from database table

[baluji <ja...@gmail.com>]

   hi,


    I am trying delete a detached instance resulting 

    Caused by: java.lang.IllegalArgumentException: Removing a detached
instance

    I am making the object persistant by using the method

    emailerScheduler= this.findById(emailScheduler.getId());

    validating whether the object is persistant by using the following
method that returns true.

  
    getJpaTemplate().contains(emailerScheduler);


    and then removing the object 

   getJpaTemplate().remove(emailerScheduler);    

    this does not result any exception.But it does not result deletion of
the data from database.

   any help will be  appreciated.

Thanks

Balu

Balu,

Your description isn't very clear, your "making the object persistant"
using findById?!  and your remove() results in an
"IllegalArgumentException: Removing a detached instance" or "does not
result any exception" ?

If you ARE trying to do em.remove() on a detached entity, what may work
(I have not tried it) is to use a
getJpaTemplate().remove(getJpaTemplate().getReference(EmailerSchedulerEn
tity.class, emailerScheduler.getId())) kind of approach.

Regards.
