Glassfish

GlassFish is an open-source application server project started by Sun Microsystems for the Java EE platform and now sponsored by Oracle Corporation. GlassFish supports all Java EE API specifications (by definition since it is the Java EE Reference implementation), such as JDBC, RMI, e-mail, JMS, web services and XML, and defines how to coordinate them. Java EE also features some specifications unique to Java EE for components.
