Hi Martin,
Thank you for your fast reply.
Removing an object from cache using broker.removeFromCache(o) and making
a new load of the object creates a new JVM object that points to the same
database object, right? If this is true, my problem remains because other
objects would still reference the old JVM object. Is there a way to reload
the object data without having to create a new JVM object?
Let me explain with some code what I want to do:
transaction.begin();
Customer c=new Customer();
c.setName("customer");
transaction.lock(c,transaction.WRITE); //persist the new customer
transaction.commit();
//after some time someone changes Customer's name to "new customer"
directly in the database
transaction.begin();
Customer c=loadCustomer(); // loads the customer persisted before
from cache
Order o=new Order();
o.setCustomer(c);
cache.reloadObject(c); //reload object data from database
boolean referenceOk=(c==o.getCustomer()); // I wanted referenceOk to
be true
boolean dataReloaded="new customer".equals(c.getName()); //I wanted
dataReloaded to be true
transaction.commit();
Thank you very much for your help.
Sincerely,
Jair Jr
