Reimplement JbpmThreadsServlet as a ServletContextListener ---------------------------------------------------------- Key: JBPM-742 URL: http://jira.jboss.com/jira/browse/JBPM-742 Project: JBoss jBPM Issue Type: Feature Request Components: Core Engine Affects Versions: jBPM 3.1.1 Reporter: Alejandro Guizar ServletContextListeners are a viable alternative to servlets for management of the jBPM scheduler/command threads. From the Servlet 2.4 spec, section 10.2: Servlet event listeners support event notifications for state changes in the ServletContext, HttpSession and ServletRequest objects. Servlet context listeners are used to **manage resources** or state held at a JVM level for the application. <<< Their intent definitely seems to match our purposes. Further below: There may be multiple listener classes listening to each event type. <<< We could have separate listeners for the scheduler and command executor so that applications may remove either of them in case the related service is not used. Section 10.2.2 provides an example. When the application starts up, the listener creates a connection to the database and stores it in the servlet context. Servlets access the connection from the context as needed. When the application shuts down, the listener closes the connection. Our listener could start the thread and store it in the servlet context, then stop it using the mechanisms provided by JBPM-741. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
