Ok, I've installed and ran the example. | 15:17:10,241 INFO [STDOUT] **** ExampleValue empty Constructor | 15:17:10,242 INFO [STDOUT] **** ExampleValue.getMessage() | 15:17:15,314 INFO [STDOUT] **** EarExampleServlet.service() | 15:17:15,336 INFO [STDOUT] *** ExampleSessionBean.getValue() | 15:17:15,336 INFO [STDOUT] **** ExampleValue String Constructor | 15:17:15,337 INFO [STDOUT] **** ExampleValue String Constructor | 15:17:15,341 INFO [STDOUT] **** ExampleValue.getMessage() | Obviously, it did not work. The example's documentation clearly states that "UseJBossWebLoader" should be "true" for it to work. However, I've had various concurrency problems when using non-isolated class-loading (for example, HttpSessions from different clients get mixed-up). Is there a way to make this work using isolation?
