- OSGi based services architecture - JOnAS is a set of OSGi bundles, technical services are OSGi services
- Modularity and extensibility - the new server architecture makes it easy to replace a service implementation or to add a new service
- Dynamic configuration - services can be started, stopped, reconfigured at runtime

- Easy and dynamic clustering with CMI V2
- multi-protocols support (RMI/JRMP, RMI/IRMI and RMI/IIOP)
- POJO load-balancing algorithms
- dynamic cluster parameters for large scale deployment: hot deployment of the cluster logic, update from jonasAdmin console
- common solution proxies based for EJB2/EJB3
- Management - JMX based, advanced web console, featured for configuration, deployment, monitoring of servers, domains and clusters
