I have some JAX-RS resources and they call inject @EJB‘s methods.

And those methods can throw for Optimistic Lock timeout.

What type of exception(s) should I catch for retrying.

javax.persistence.OptimisticLockException?

javax.ejb.EJBException?


class MyResource {

    @GET
    public Response doSomething() {
        for (int i = 0; i < 3; i++) {    
            try {
                myEJB.doSomething();
                break;
            } catch (????) {
                // I just want to know the exact type of Exception
                // for lock wait timeout
            }
        }
    }

    @EJB
    private MyEJB myEJB;
}

Here comes the stack trace.

Lock Wait Timeout, it is a Pessimistic Locking. Make supported lock modes ares :

PESSIMISTIC_READ – which represents a shared lock.
PESSIMISTIC_WRITE – which represents an exclusive lock.

LockTimeoutException is thrown when

An EntityManager instance try to do PESSIMISTIC_READ lock, another EntityManager holds PESSIMISTIC_WRITE lock.
An EntityManager instance try to do PESSIMISTIC_WRITE lock, another EntityManager holds PESSIMISTIC_WRITE lock or PESSIMISTIC_READ lock.

You can configure timeout milliseconds with javax.persistence.lock.timeout in persistence.xml.

<properties>
   <property name="javax.persistence.lock.timeout" value="1000"/>
</properties>

For more reference Locking in JPA

I am not sure you need to catch OptimisticLockException or not. But it is sure you will get OptimisticLockException if your entity used @Version annotation.
