Hello everybody,
I have two threads executing a findby.... method (from an entity bean) almost at the
same time in a STATELESS session bean but one of them is deleting a record in the
database. Thus, the other one complains with the following error:
javax.ejb.NoSuchObjectLocalException: Entity not found:
primaryKey=11e1813-fbd1ae2521-b88d8e8d57a53bc420279153d2e46f6f

org.jboss.ejb.plugins.SecurityInterceptor.invoke(SecurityInterceptor.java:117)
at org.jboss.ejb.plugins.LogInterceptor.invoke(LogInterceptor.java:191)
...
I have declared all my finder methods from the entity bean and the method that calls
these finders in the STATELESS session bean to be transaction type "Required" and NOT
read only.
I thought that if a method is not read-only then only one thread can execute at one
time (Transaction locking).
How can I accomplish that?
Thanks in advance,
jchang
By the way, I am using JBoss 3.2.1 and EJB 2.0
