About JOnAS

JOnAS provides support of J2EE 1.4 including EJB^TM 2.1, JTA^TM 1.0.1, JDBC 3.0, J2EE CA 1.5, JMX^TM 1.2, JNDI^TM 1.2.1, JMS^TM 1.1, JavaMail^TM 1.3, Servlet^TM 2.4, JSP^TM 2.0, JAAS^TM 1.0, JACC^TM 1.0, Web Services 1.1, JAX-RPC^TM 1.1, SAAJ^TM 1.2, JAXR^TM 1.0, J2EE Management 1.0, JAF^TM 1.0, JAXP^TM 1.2 specifications. JOnAS is architectured in terms of services. The main components of JOnAS are:

An Ear Service, for deploying J2EE applications packaged as EAR files,
EJB containers provided by a set of Java classes and a tool to generate interposition classes (JORM and MEDOR are used to provide Container Managed Persistence)
A Web Container Service, to run Servlet/JSP engines as a JOnAS service (currently Tomcat or Jetty)
A Transaction Manager, JOTM, providing JTA support and distributed transaction coordination
A JMS Service using JORAM (other JMS implementations are easily pluggable; for example, a service class for MQ Series is available)
A Database Manager providing JDBC support and connection pooling
A Security Service
A Server Management Service, based on a JMX model and providing a Struts based GUI
A Connector Resource Service for deploying J2EE CA-compliant Resource Adapters (connectors for JDBC and JMS/JORAM are provided, they may be used in replacement of the Database and JMS services)
A Mail Service providing application components with the necessary resources to send e-mails,
A "Web Services" service providing support of Web Services on top of Axis,
A Communication service providing support of RMI on top of several protocols simultaneously: jrmp, irmi, iiop; for jrmp and irmi, local call optimization is provided
A "Discovery" service for automatic domain members management
An "HA" service for dealing with Stateful Session Beans replication within clusters
The JOnAS product includes Hypersonic SQL. This lightweight database (hsqldb) provided through a JOnAS service (db) allows to run JOnAS examples and "non DB intensive" applications without further download and configuration.

A set of tools to develop, deploy and manage EJBs are also provided. JOnAS supports clustering architectures, providing load balancing and failover both at HTTP and RMI levels.
