This plugin became obsolete by Apache Camel - Hippo Events Support. Please try to use that module instead.
Hippo Repository provides DaemonModule interface to allow developers to build a custom daemon module to interact with Repository.
Spring Daemon Module provides a DaemonModule implementation which creates a Spring Application Context. So, you can just use Spring Application Context configuration in classpath:org/onehippo/forge/springdaemon/SpringDaemonModule.xml for your job processings.
Therefore, instead of implementing Daemon Modules for each task, you can just put Spring's built-in scheduler bean configurations and your POJOs in the Spring Application Context configuration with this generic module.
Note: Sprign Daemon Module does not care any clustering issues by itself. So, if you need to run a daemon module for a scheduling job only in single cluster node, then you should configure the scheduler components properly. For example, you may choose Quartz scheduler component configuration with JDBC JobStore instead of copying & pasting the example shown in the examples.
The latest version of the Spring Daemon Module is 1.01.00.
