The Quartz integration is available as two components: the report manager and support for deployable reports. These components build on each other, so you can use the report manager alone or the report manager in conjunction with deployable reports.
If you use the report manager alone, this activates a report manager service integrated into the Geronimo environment. Other applications or components running in Geronimo can access this report manager by using a GBean reference. To configure and generate reports in this scenario, you'll just deal with the report manager.
The deployable reports plugin lets you deploy individual reports or groups of jobs as Geronimo deployment components. There is no difference to the Jasper XML template for a job, this just provides the packaging allowing you to create a JAR with the report templates and the report parameters such as the database connection pool to use (if any), default report criteria, whether to archive the report, and more. Then you can deploy, start, stop, and undeploy the reports using the standard Geronimo deployment tools.
