libgeronimo-activation-1.1-spec-java binary package in Ubuntu Precise i386

 Apache Geronimo is an open source application server developed by the Apache
 Software Foundation and distributed under the Apache license. Geronimo is
 currently compatible with the Java Enterprise Edition (Java EE) 5.0
 specification.
 .
 The JavaBeans Activation Framework (JAF) extension to Java allows developers
 to determine the type of an arbitrary piece of data, to encapsulate access to
 it, to discover the operations available on it, and to instantiate the
 appropriate bean to perform said operation(s). For example, if a browser
 obtained a PNG image, JAF would help the browser to identify that stream of
 data as a PNG image, and the browser can instantiate an object to display that
 image.
 .
 Another DFSG free JAF implementation is available from the Glassfish project.
