Hi!
Everytime I use a read-only pattern(get*) on my EntityBean, the pessimistic locking stops working (for other methods also)! It behaves just like optimistic locking. I experimented for a few days, I read the forums and the JBoss 4.0 Book, there is nothing on this behaviour.
some of the xdoclet tags (the ones that count):
| /**
| * Autogenerated EJB implementation class for SystemKontoEB
| *
| *
| *
| * @ejb.bean
| * generate = "true"
| * name = "SystemKontoEB"
| * type = "CMP"
| * cmp-version = "2.x"
| * view-type = "local"
| * local-jndi-name = "ejb/SystemKontoEB"
| * reentrant = "true"
| *
| * @jboss.container-configuration
| * name = "Standard CMP 2.x EntityBean Pessimistic"
| *
| * @jboss.cache-invalidation
| * value = "true"
| *
| * @jboss.cache-invalidation-config
| * invalidation-group-name = "SystemKontoEBGroup"
| *
| * @jboss.tuned-updates
| *
| * @jboss.entity-command
| * name = "no-select-before-insert"
| *
| * @jboss.read-ahead
| * strategy = "on-load"
| * page-size = "20"
| *
| * @ejb.util
| * generate = "physical"
| *
| * @ejb.transaction
| * type = "Required"
| *
| * @ejb.persistence
| * table-name = "SYSTEMKONTO"
| *
| * @jboss.method-attributes
| * pattern = "get*"
| * read-only = "true"
| */
|
"Standard CMP 2.x EntityBean Pessimistic" is the same as "Standard CMP 2.x EntityBean" only with the modifications below. I use my own invalidation methods, if you wonder why i do this.
| <locking-policy>org.jboss.ejb.plugins.lock.QueuedPessimisticEJBLock</locking-policy>
|
Any ideas why the read-only method tag (get*) would interfere with the pessimistic locking of other methods which don't match the get* pattern?
