Hello,
I'm facing a curious problem, trying to expose Hibernate's statistics through JMX.
I updated jboss-service.xml to add the following:
| <mbean code="org.hibernate.jmx.StatisticsService"
|
name="jboss.monitoring:service=StatisticsService,name=xxxStatisticsService">
|
| <attribute name="StatisticsEnabled">true</attribute>
| <attribute
name="SessionFactoryJNDIName">persistence.units:ear=xxx.ear,jar=xxx.jar,unitName=xxx_pu</attribute>
|
| </mbean>
|
When JBoss AS starts, I receive the following error:
16:36:46,532 INFO [Server] Core system initialized
| 16:36:53,188 ERROR [StatisticsService] Error while accessing session factory with JNDI
name persistence.units:ear=xxx.ear,jar=xxx.jar,unitName=xxx_pu

Please note that this occur every time for this JNDI attribute, but not if I set a simple
value (i.e. a plain string with no special char).
However, once the server is started, I can access my MBean through the JMX console, set
the SessionFactoryJNDIName attribute with the same value, and then see updated Hibernate
statistics as I first expected. I double-checked this value, which seems to be the real
JNDI name for my Hibernate SessionFactory.
I guess this is a JBoss AS issue, but how can I solve this, or work around this?
