What happens when i update a bean to fix a bug, and deploy it using hot deployment.
Can i keep the old instances of the bean running, while requests for new beans can get updated bean instances.
When you use the hot deployment feature (for updation of beans), the currently-loaded implementation classes for the EJB are immediately marked as unavailable in the server, and the EJB's classloader and associated classes are removed. WebLogic Server automatically propagates a RedeploymentException to all clients that were using the bean. At the same time, a new EJB classloader is created, which loads and maintains the revised EJB implementation classes.When clients next acquire a reference to the EJB, their EJB method calls use the updated EJB implementation classes.
