Apache Geronimo 2.1.x implements JAX-RPC 1.1 and JAX-WS 2.0 specifications and therefore it supports the Web Services standards outlined in these specifications. For example, Geronimo supports SOAP 1.1, SOAP 1.2, WSDL 1.1, WSDL 2.0, WS-I Basic Profile 1.0, and WS-I Basic Profile 1.1.

Other Web Services standards such as WS-Security or WS-Addressing are currently not supported in Geronimo. The support for these (and other) standards will be added in the future releases.
