Error "Write operations are not allowed in read-only mode (FlushMode.NEVER/MANUAL)"

[Vinod Vinu]

iam getting the following error on my console of eclipse:-

    
org.springframework.dao.InvalidDataAccessApiUsageException: Write operations are not allowed in read-only mode (FlushMode.NEVER/MANUAL): Turn your Session into FlushMode.COMMIT/AUTO or remove 'readOnly' marker from transaction definition.

We are using setter bean injection (DI) of Spring.

Spring annotation defined in the service class is:-

    
@spring.bean
 *   id     = "pr.AddToDraftServiceReadOnly"
 *   parent = "BaseService"

What is the reason behind it ?



If i change the id defined above to ReadWrite then it works but i don't know its reason, why it is so?
Please explain me in detail why ?

thanks in advance

ReadOnly means that your code will only read in data, never try to write it. If you try to write it, it will fail, because you told it you were only going to do reads.

Setting your transaction to ReadOnly does some stuff to turn off Flushing for writes.
