Signficant changes, from the official release notes:
Geronimo applications, server features, and integrated products can be distributed as Geronimo plugins. Plugins are easy to install, automatically download any dependencies, and do not require server restarts. Using the plugin infrastructure, applications or modules can be copied from one Geronimo installation to another (from developer to developer, test to production, etc.). - Deployment plans have been updated, ConfigId has been replaced by a more complete ModuleId structure. Previous releases of Geronimo will require modifications, refer to the Geronimo documentation for further details.
- Tools and commands have been also updated to reflect the ConfigID -> ModuleId change as well as geronimo-config-1.1.xsd -> geronimo-module-1.1.xsd schemas.
- More functionality has been included in the Administrative Console (http://localhost:8080/console/). Memory utilization graphics, more Thread Pools, remote HTTPd configuration wizard and plugins are some of these new features.
- All the applications (except for those deployed via Hot Deployment) are stored in the
/repository directory. Previous config-store has been removed. Enhanced SMTP support. Keystore configuration. Geronimo also supports in-place deployments. This means an archive or a directory can be deployed without being copied into the Geronimo directory structure. Little-G is an alternative distribution offered in Geronimo 1.1. This new distribution has a reduced footprint. It comes with either Tomcat or Jetty as WebContainer options.
