[jboss-user] [JBossCache] - statistics not refreshing

[jzmmek2k2]

We are currently integrate jboss-cache in our project and it works really good. But the only thing not working is the statistic-mbeans (neither in jmx-console nor in jconsole). The only attribute which refreshes is the time elapsed since starting/reset.

This is our environment:

- Linux
- JBossCache-1.4.0.SP1
- Sun JDK 1.5
- jboss-4.0.4.GA-ejb3

And this is out configuration (this is very similar to 'local-service.xml'):

  | 
  |     </mbean>

In our tests have simply get/put some java.lang.String objects in the cache:




We have used both ways (jndi & programmatic) to embedd the cache in jboss, but without any difference.

...
  | Object x = cache.getObject(Fqn.fromString("/a1"));
  | cache.putObject(Fqn.fromString("/a1"), "hello world");
  | x = cache.getObject(Fqn.fromString("/a1"));
  | ...
  | 


It would be really great if someone can help me, because we cannot do any production-planning without any statistics.
